Answer:

0.312 moles of H2O

Explanation:

no. of moles of ch4= mass ÷ molar mass

=2.5 ÷ 16.04

=0.156 moles of ch4

According to balanced chemical equation

CH4 : H2O

1 mole : 2 moles

0.156 moles : x moles

by cross multiplication

x= (0.156x2) ÷ 1

= 0.312 moles of H2O

What is the mass of solid NH4Cl formed when 75.5g of NH3 is mixed with an equal mass of HCl? What is the volume of the gas remai

taurus [48]

Answer:The volume of the remaining gas that is ammonia is 23.85 L.

Explanation:

$NH_3(g)+HCl(g)\rightarrow NH_4Cl(s)$

Moles of $NH_3=\frac{\text{mass of} NH_3}{\text{Molar mass of}NH_3}=\frac{75.5 g}{17.03 g/mol}=4.43 mole$

Moles of HCl of gas = $\frac{\text{mass of} HCl}{\text{Molar mass of}HCl}=\frac{75.5 g}{36.5 g/mol}=2.06 mol$

According to reaction 1 mole of HCl reacts with 1 mol of $NH_3$ then 2.06 moles of HCl will react with = 2.06 moles of $NH_3$

Moles left of ammonia left = 4.43 - 2.06 = 2.36 moles

Volume of the gas will be given by Ideal gas equation: PV=nRT

Pressure = 752 mmHg = 752 × 0.0031 atm = 2.33 atm

R = 0.08026 L atm/K mol

V = ? , n = number of moles of ammonia

Temperature = 14 °C = 14 + 273 K = 287 K(0°C = 273K)

$V=\frac{2.36 mol\times 0.08206 L atm/K mol\times 287 K}{2.33 atm}=23.85 L$

The volume of the remaining gas that is ammonia is 23.85 L.

As the mass of an object increases, what happens to the gravitational force created by that object?

alexandr1967 [171]

Answer:

the gravitational force is proportional to the mass of both interacting objects, bigger objects will attract each other with a greater gravitational force. So the mass of either object increases, the force of gravitational attraction between them also increases.
