Answer:red, orange, yellow, green, blue, indigo and violet.

Explanation:

Answer:

C

Explanation:

The solution that will reach dynamic equilibrium is a saturated solution. The correct option is C.

A chemical solution in which the solute concentration is less than its equilibrium solubility is known as an unsaturated solution.

The solvent dissolves the entire solute.

When a solute (typically a solid) is mixed with a solvent (commonly a liquid), two reactions take place at the same time.

Thus, the correct option is C, the saturated solution.

Answer:

alpha < beta < gamma.

Explanation:

Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.

An electromagnetic spectrum refers to a range of frequency and wavelength that an electromagnetic wave is distributed or extends. The electromagnetic spectrum comprises of gamma rays, visible light, ultraviolet radiation, x-rays, radio waves, and infrared radiation.

Generally, all radioactive elements are capable of emitting radiation. The three (3) types of nuclear radiation from least damaging to most damaging are; alpha, beta and gamma.

This ultimately implies that, alpha particles have the least damaging (penetrative) ability followed by beta particles and lastly, gamma rays.

Given: F = 6 J, a = 3 m

To find: What is  the mass of the apple?

Formula: [tex]m=\frac{2KE}{v^2}[/tex]

Solution: Newtons are derived units, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared.

M = F ÷ a

F = 6 kg ÷ 3 m/s2

F = 2 N

PE = mgh 6 J= (3m) (9.8 m/s2²) (__m) m= 0.20 Kg

Answer:

The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.

Answer:

A positive acceleration means and increase

A negative acceleration is a decrease

a zero acceleration is a constant movement so its not increasing or decreasing just constant

Explanation:

What is a positive acceleration ?

If the velocity of an object increases with time, its acceleration is positive.

What is a zero acceleration ?

Zero acceleration is an acceleration, just with zero magnitude. Motion with constant velocity is just a special case of motion with uniform acceleration.

What is a negative acceleration ?

A negative acceleration means you will subtract from the current value of the velocity, and a positive acceleration means you will add to the current value of the velocity. ... And if the acceleration points in the opposite direction of the velocity, the object will be slowing down.

If 36g of Al react with 34L of Oz, 0.667 moles of Al2O3 are produced. The correct option is b, 0.667 moles

The mole is a SI unit of measurement that is used to calculate the quantity of any substance.

[tex]\rm 4Al +3O_2 -- > 2Al_2O_3[/tex]

Step1- calculate the moles of aluminum

The mass of Al is 36 g

The molar mass of Al is 27

[tex]\rm Number\;of \;moles= \dfrac{mass}{molar\;mass}\\\rm Number\;of \;moles\;of\;Al = \dfrac{36}{27} = 1.33\;mol[/tex]

Step2- calculate the moles of oxygen

The mass of O₂ is 34 L

[tex]\rm 1 L = \dfrac{1}{22.4 }[/tex]

[tex]\rm Number\;of \;moles\;O_2= \dfrac{34}{22.4} = 1.51[/tex]

The limiting reagent is 1.33 MOL. By the rule of stoichiometry, four moles of Al produced 2 moles of Al.

[tex]\rm \dfrac{1.33}{2} = 0.665 \;moles[/tex]

Thus, the correct option is b. 0.667 moles.

Answer:

The new volume is 1.993 L

Explanation:

The gas laws are a set of chemical and physical laws that allow determining the behavior of gases in a closed system. The parameters evaluated in these laws are pressure, volume, temperature and moles.

Boyle's law says that the volume occupied by a certain gaseous mass at constant temperature is inversely proportional to the pressure. This law is expressed mathematically as:

P*V=k

Gay-Lussac's law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions with the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature. This law indicates mathematically that the quotient between pressure and temperature is constant:

[tex]\frac{P}{T}=k[/tex]

Finally, Charles's law indicates that as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases. In summary, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:

[tex]\frac{V}{T}=k[/tex]

Combined law equation is the combination of three gas laws called Boyle's, Charlie's and Gay-Lusac's law:

[tex]\frac{P*V}{T}=k[/tex]

Analyzing an initial state 1 and a final state 2, it is satisfied:

[tex]\frac{P1*V1}{T1}=\frac{P2*V2}{T2}[/tex]

In this case:

Replacing:

[tex]\frac{500 kPa*3 L}{323 K}=\frac{240 kPa*V2}{103 K}[/tex]

Solving:

[tex]V2=\frac{103 K}{240 kPa} *\frac{500 kPa*3 L}{323 K}[/tex]

V2=1.993 L

The new volume is 1.993 L

In simple terms it is when two chemicals bond with each other

Explanation:

For more detailed explanation here's your answer:-

Explanation:

An element is define as a substance which contains only those atoms which have same number of protons. Basically, an element contains atoms of one type only.

For example, a piece of sodium metal will contain only atoms of sodium.

An element can never be divided further into simpler substances. So, in the given figure box 1 is containing atoms of only blue color is an element.

A compound is a substance formed by the chemical combination of two or more different atoms present in a fixed ratio.    

For example, [tex]MgCl_{2}[/tex] is a compound which contains atoms of Mg and Cl in a 1:2 ratio.

The box containing pink and yellow balls in not a compound because here atoms are not chemically combined to each other but they are just present as individual atoms in same box. Hence, this is not a compound.

Therefore, when one or more elements are in a fixed ratio joined together they form a compound.

Answer:

Both roots are imaginary roots.

Explanation:

Consider these things:

If we try to solve x²+1 = 0, notice that we aren't able to solve the equation in Real Number system because there are no negative outputs for quadratic function.

Remember that quadratic function has range greater or equal to the max-min value.

x-axis plane represents the solutions of that equation. If a graph intersects x-axis plane then it has a solution.

While a graph that doesn't have any intersects on x-plane, it means that the equation for that graph doesn't have real solutions but imaginary solutions.

As you may notice some of parabola graph has one intersect, two intersects or none. One intersect is one solution to the equation — Two intersects are two solutions of the equation and lastly, no intersects mean that no real solutions and remain only imaginary solution.

Answer:

If you hace 4 moles of CaCl₂, you can make 8 moles of HCl.

Explanation:

The balanced equation is

CaCl₂ + 2 H₂O → Ca(OH)₂ + 2 HCl

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction) , the following amounts of each compound participate in the reaction:

Then you can apply the following rule of three: if by stoichiometry 1 mole of CaCl₂ forms 2 moles of HCl, 4 moles of CaCl₂ form how many moles of HCl?

[tex]moles of HCl=\frac{4 moles of CaCl_{2}*2 moles of HCl }{1mole of CaCl_{2}}[/tex]

moles of HCl= 8

If you hace 4 moles of CaCl₂, you can make 8 moles of HCl.

Answer: The heat energy absorbed by glass window is 84420 J.

Explanation:

Given: Mass = 15 kg (1 kg = 1000 g) = 15000 g

Initial temperature = [tex]20^{o}C[/tex]

Final temperature = [tex]26.7^{o}C[/tex]

Specific heat capacity = [tex]0.840 J/g^{o}C[/tex]

Formula used is as follows.

[tex]q = m \times C \times (T_{2} - T_{1})[/tex]

where,

q = heat energy

m = mass of substance

C = specific heat capacity

[tex]T_{1}[/tex] = initial temperature

[tex]T_{2}[/tex] = final temperature

Substitute the values into above formula as follows.

[tex]q = m \times C \times (T_{2} - T_{1})\\ q = 15000 g \times 0.840 J/g^{o}C \times (26.7 - 20)^{o}C\\q = 84420 J[/tex]

Thus, we can conclude that the heat energy absorbed by glass window is 84420 J.

Answer:

C is the answer I believe.

Recall that the determining factors for spontaneity of a reaction are the enthalpy and entropy changes that occur for the system. The free energy change of a reaction is a mathematical combination of the enthalpy change and the entropy change.

When both cases are satisfied, i.e. if the change in enthalpy is negative and the change in entropy is positive, the reaction is said to be spontaneous, and thus, enthalpy and entropy are the two driving thermodynamic forces of chemical reactions.

Combustion reactions, such as this fire, are spontaneous reactions. Once the reaction begins, it continues on its own until one of the reactants (fuel or oxygen) is gone. A nonspontaneous reaction is a reaction that does not favor the formation of products at the given set of conditions.

A spontaneous reaction is a reaction that favors the formation of products at the conditions under which the reaction is occurring. ... The entropy of the system increases during a combustion reaction. The combination of energy decrease and entropy increase dictates that combustion reactions are spontaneous reactions.
