Explanation:

The rate of reaction is expressed as decrease in concentration of reactant or increase in product per unit time. It is also defined as the increase of concentration of the product per second.

Answer:

Explanation:

Reaction rate, in chemistry, the speed at which a chemical reaction proceeds. ... It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.

Answer:

10.0g of solute before reaching saturation

Explanation:

A saturated solution is the solution that contains the maximum amount of solute that can be dissolved. In the problem, you can have

50.0g of solute / 500.0g Solvent

Now, in 800.0g solvent you can dissolve:

800.0g Solvent * (50.0g solute / 500.0g Solvent) = 80.0g of solute can be added

As you dissolve initially 70.0g of solute. You can add:

80.0g - 70.0g =

Answer:

The correct answer is - 4 m/s

Explanation:

Given:

time = 20 sec

velocity= 80 m/s

Accelaration = ?

Solution:

formula for the accelaration can be drive from the for

vi = vf + ( a.t)

0 m/s (rest) = 80 m/s + (a.20s.-1)

a.20.-1= -80,

we check if this is true;

0 m/s= 80 + -80 = 0 so its true.

so a.20.-1= -80,

a= 80/20 ,

Thus, the correct answers a = 4 m/s

Answer:

By pass surgery.

Explanation:

Kayla is suffering with blocked artery. The doctors have tried to open up her blocked artery with injecting the stunt by angioplasty process. The treatment had been unsuccessful and she is still complaining chest pain. The next move of the doctors would be by pass surgery which will open up the blocked artery. There are many risks involved in this surgery. The patient may get into coma due to excess bleeding or she may die if her blood pressure shoots up during surgery.

Answer: The total mass of reactants and products is the same during a chemical reaction.

Explanation:

the total mass of reactants is equal to the total mass of products.

Answer:

m = 43.87 grams

Explanation:

Given that,

Number of moles, n = 1.29 moles

The molar mass of H₂O₂ is, M = 34.0147 g/mol

We know that,

[tex]n=\dfrac{m}{M}[/tex]

Where

m is mass of H₂O₂

So,

[tex]m=n\times M\\\\m=1.29\times 34.0147 \\\\m=43.87\ g[/tex]

So, there are 43.87 grams of H₂O₂.

Answer:

[tex]n_{NaOH}=7.0molNaOH[/tex]

Explanation:

Hello there!

In this case, according to the given information about this problem, we first consider the given chemical reaction:

2Na + 2H2O --> 2NaOH + H2

Whereas there is 2:2 mole ratio of NaOH to Na; thus, we calculate the required theoretical yield of NaOH in moles as shown below:

[tex]n_{NaOH}=7.0molNa*\frac{2molNaOH}{2molNa} \\\\n_{NaOH}=7.0molNaOH[/tex]

Answer:

I believe the answer is A (changes in air temperature  result in differences in air pressure which causes wind). Hope this helps

Explanation:

The voltage is the potential difference between the two ends of the conductor. The factor that does not affect the voltage produced in a voltaic cell is pressure. The correct option is B.

A voltaic cell uses a chemical reaction to convert electrochemical energy to electrical energy. It consists of cathode and ions which flow through the cathode and anode.

The pressure has nothing to do with the Electrochemical devices.

The factor does not influence the voltage produced in a voltaic cell is pressure. The correct option is B.

Answer: There are 3.2 moles of gas if you have a volume of 38.0 L under a pressure of 1430 mmHg at standard temperature.

Explanation:

Given: Volume = 38.0 L

Pressure = 1430 mm Hg (1 mm Hg = 0.00131579 atm) = 1.9 atm

Temperature = 273.15 K

Using ideal gas equation, the moles of gas will be calculated as follows.

[tex]PV = nRT\\[/tex]

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T =temperature

Substitute the values into above formula as follows.

[tex]PV = nRT\\1.9 atm \times 38.0 L = n \times 0.0821 L atm/mol K \times 273.15 K\\n = \frac{1.9 atm \times 38.0 L}{0.0821 L atm/mol K \times 273.15 K}\\= 3.2 mol[/tex]

Thus, we can conclude that there are 3.2 moles of gas if you have a volume of 38.0 L under a pressure of 1430 mmHg at standard temperature.

During photosynthesis, plants incorporate atmospheric pressure into more complex energy-storage molecules that increase the mass of the plants. Plants need sunlight for this process because plants transform light energy into chemical energy stored in the molecules.

It is the process by which plants , algae and some bacteria uses water from the carbon dioxide, air and soil and in this process food is prepared in the presence of chlorophyll and sunlight. In this process light energy converted to chemical energy.

Thus, we can say that During photosynthesis, plants incorporate atmospheric pressure into more complex energy-storage molecules that increase the mass of the plants. Plants need sunlight for this process because plants transform light energy into chemical energy stored in the molecules.

Answer:

0.10 % w/w

Explanation:

The percent by mass (%w/w) is defined as one hundred times the ratio between the mass of solute (In this case aspirin, 0.05g) and the mass of solution (Mass solute + mass of water = 0.05g + 50g = 50.05g). The percent by mass is:

0.05g Aspirin / 50.05g * 100 =

0.10 % w/w

Answer:

0.97

Explanation:

Let R₁ represent the rate of diffusion of NO.

Let R₂ represent the rate of diffusion of CO.

Molar mass of NO (M₁) = 14 + 16 = 30 g/mol

Molar mass of CO (M₂) = 12 + 16 = 28 g/mol

Thus, the rate of NO to CO can be obtained as follow:

R₁ /R₂ = √(M₂/M₁)

R₁ /R₂ = √(28/30)

R₁ /R₂ = √(28/30)

R₁ /R₂ = 0.97

R₁ : R₂ = 0.97

NO : CO = 0.97

Therefore, the rate of diffusion of NO to CO is 0.97
