Answer 1

The question is incomplete, the complete question is:

A curium-245 nucleus is hit with a neutron and changes as shown by the equation. Complete the equation by filling in the missing parts.

[tex]_{96}^{245}\textrm{Cm}+_0^1\textrm{n}\rightarrow _{42}^{103}\textrm{Mo}+_{r}^{q}\textrm{p}+3_0^1\textrm{n}[/tex]

Answer: The complete equation formed is [tex]_{96}^{245}\textrm{Cm}+_0^1\textrm{n}\rightarrow _{42}^{103}\textrm{Mo}+_{54}^{140}\textrm{Xe}+3_0^1\textrm{n}[/tex]

Explanation:

The general representation of an isotope is given as:

[rex]_Z^A\textrm{X}[/tex]

where,

A is the mass number, Z is the atomic number and X is the symbol of the element

In a nuclear reaction, total atomic number and total mass number on either side of the reaction remains the same

For the given chemical reaction:

[tex]_{96}^{245}\textrm{Cm}+_0^1\textrm{n}\rightarrow _{42}^{103}\textrm{Mo}+_{r}^{q}\textrm{p}+3_0^1\textrm{n}[/tex]

On the reactant side:

Total atomic number = [96 + 0] = 96

Total mass number = [245 + 1] = 246

On the product side:

Total atomic number = [42 + r + 0] = 42 + r

Total mass number = [103 + q + 3] = 106 + q

Calculating for 'r' and 'q', we get:

[tex]96= 42 + r\\\\r=96-42=54[/tex]

[tex]246 = 106+q\\\\q=246-106=140[/tex]

Thus, the missing isotope is [tex]_{54}^{140}\textrm{Xe}[/tex]

Hence, the complete equation formed is [tex]_{96}^{245}\textrm{Cm}+_0^1\textrm{n}\rightarrow _{42}^{103}\textrm{Mo}+_{54}^{140}\textrm{Xe}+3_0^1\textrm{n}[/tex]

how many moles of H2 are required to make 10 moles of water?​

Answers

Explanation:

10 moles h20 is required

10 moles of H₂ are required to make 10 moles of H₂O.

What is Stoichiometry ?

Stoichiometry is an important concept which helps us use the balanced chemical equation to measures the amount of reactants and products.

What is Balanced Chemical equation ?

A balanced chemical equation is chemical equation that has equal number of atoms on both sides of arrow that is reactant and product.

First we have to write the Balanced chemical equation

2H₂ + O₂ → 2H₂O

To produce 2 moles of water, 2 moles of hydrogen are required to produce 10 moles of water.

So,

[tex]\frac{2\ \text{moles of}\ H_2}{2\ \text{moles of}\ H_2O}[/tex] × 10 moles of H₂O

= 10 moles of hydrogen are required.

Thus, from above conclusion we can say that 10 moles of H₂ are required to make 10 moles of H₂O.

Natural gas is mined along with crude oil in many oil wells. It has the advantage of being a cheap fossil fuels which is easily obtainable.

Generally, natural gas is the cleanest of all the fossil fuels. This means that it is the fossil fuel that least contributes to environmental pollution.

On the other hand; natural gas produces some amount of sulphur as it is burnt and mercury as particulate matter. These substances are quite dangerous to health.

Answers

Answer:

Explanation:

Copper (II) substances burn to produce bluish-green flames.

Flame test for copper (II)

The copper (II) present in the wood will make the flame produce a bluish-green color.

This is because copper (II) compounds are known to produce flame colors that range from blue to bluish-green when tested in the laboratory.

This is because the electrons in the atoms of copper lose energy and drop to lower energy, releasing the lost energy as light in the process.

Let's start by figuring out the amount in miles. From there, we can easily find the equivalent mass. Which equation do we need to find out how many moles of NH4Cl would there be in 500 mL of a 0.300 M solution of it?

A. n=C x V
B. C=V x n
C. C=n x V
D. n=C / V

Answers

Answer:

A. n= C x V

Explanation:

Molarity of a solution is the molar concentration of that solution. It can be calculated using the formula:

M = n/V

Where;

M = molarity (M)

n = number of moles (n)

V = volume (mL)

To calculate the number of moles from a given molarity value and volume, we say:

n = M × V

For this case of NH4Cl;

V = 500mL = 500/1000 = 0.5L

M = 0.300 M

n = 0.300 × 0.5

n = 0.15moles

Answer: n=CxV

How many moles of oxygen gas are consumed in the production of 5.00 g of iron(III) oxide from metallic iron? 4Fe(s)+3O2(g)→2Fe2O3(g) _____ mole(s) O2

Answers

Answer:

0.0469 mol of 02.

Explanation:

The balanced equation of this reaction is given as follows:

4Fe(s) + 3O2(g) → 2Fe2O3(s)

According to this equation, 3 moles of oxygen gas (O2) is consumed to produce 2 moles of iron(III) oxide (Fe2O3).

Using the formula, mole = mass/molar mass to convert mass of Fe2O3 to mole

Molar mass of Fe2O3 = 56(2) + 16(3)

= 112 + 48

= 160g/mol

mole = 5.00 g ÷ 160g/mol

mole = 0.03125mol of Fe2O3

Since 3 moles of oxygen gas (O2) is consumed to produce 2 moles of iron(III) oxide (Fe2O3).

0.03125mol of Fe2O3 will be produced when (0.03125 × 3/2) mol of oxygen gas is consumed.

0.03125 × 3/2

0.03125 × 1.5

= 0.0469 mol of 02.

Process name of water vapor to ice

Answer:

Deposition

this is the process of a substance changing its state from gas to solid. Solid to gas is known as sublimation

Please mark brainliest

Water is a liquid and its solid form is known as ice. When the water converts from the liquid phase (that is, water) to the solid phase (that is, ice), the process is known as freezing.
Water freezes at 0 degrees Celsius at standard atmospheric pressure, while it is present as liquid water between a temperature of 0 degrees Celsius and 100 degrees Celsius. Heat is lost to the surroundings as the water freezes. The ethalapy of fusion of water or heat of fusion of water is 6 kJ/mol. That is, for freezing 1 mole of water at 0 degrees Celsius, 6 kJ of heat is lost to the surroundings or is given out. Thus, freezing is an exothermic process.
Note that freezing refers to the phase change from liquid to solid and does not involve any change in the temperature of water.
