The correct answer is potential energy.

Potential energy is when an object can store energy as the result of its position.

Gravitational potential energy is the energy stored between an object and the Earth.

Elastic potential energy is the energy stored in objects that are compressed or stretched.

Chemical potential energy is the energy stored in the bonds between atoms.

Zn + 2 HCl ZnCl2 + H2

son4ous [18]

Answer:

0.153 moles of hydrogen.

B) Multiply 10 grams of Zn x (1 mol Zn/65.39 g)

Explanation:

Given data:

Mass of zinc = 10 g

Moles of hydrogen = ?

Solution:

Chemical equation:

Zn + 2HCl → ZnCl₂ + H₂

Number of moles of zinc:

Number of moles of zinc = mass/ molar mass

Number of moles of zinc = 10 g/ 65.4 g/mol

Number of moles of zinc = 0.153 mol

Now we will multiply the moles of Zn with hydrogen:

Zn : H₂

1 : 1

0.153 : 0.153

5.0 L vessel holds 3.0 mol n2, 2.0 mol f2, and 1.0 mol h2 at 273 K. What is the partial pressure of fluorine?

xz_007 [3.2K]

Answer:- 8.97 atm.

Solution:- Moles of each gas, volume of the vessel and temperature are given. So, we could easily use the partial pressure of each gas using ideal gas law equation.

PV = nRT

P is the pressure, V is the volume, n is the moles of the gas, R is universal gas constant and T is kelvin temperature.

The equation is rearranged for the pressure as:

$P=\frac{nRT}{V}$

To calculate the partial pressure of fluorine we will use its moles.

n = 2.0 mol

V = 5.0 L

T = 273 K

R = 0.0821 $\frac{atm.L}{mol.K}$

P = ?

Let's plug in the values and calculate the partial pressure of fluorine.

$P=\frac{2.0mol*0.0821\frac{atm.L}{mol.K}*273K}{5.0L}$

P = 8.97 atm

So, the partial pressure of fluorine gas is 8.97 atm.
