8) 21.504 liters of gas

9) 122.5 g

10) 6.022*10^23

Explanation:

8)

1 mole= 22.4 liters

to calculate the volume of gas of 0.960 moles of CH4

22.4*0.960/1

= 21.504 liters of gas  

9)

2.0 mole*18.02 g/ 1 mole

=122.5 g

10)

2.0 l * 1 mole/22.4 l

6.022*10^23

Look at the following enthalpy diagram. Select all that apply.
Drupady [299]

Answer:

Option 2 and 4 are correct

Explanation:

The reactants in the attached image have more enthalpy and hence less stability as they are more reactive. Thus, Product is more stable than the reactants.

This is an addition reaction in which two reactants add up to form the product.

Very less activation energy is required as the reactants themselves are unstable, possess high energy and hence are very reactive.

Reactants have more energy than the products.

Which substance most likely has the strongest intermolecular forces?
serious [3.7K]

Answer: -

Acetic acid

Explanation: -

The intermolecular force of attraction depends on the strength or extent of Hydrogen bonding present in a substance.

Benzene and chloroform does not have hydrogen bonding being non polar molecule.

Water has hydrogen bonding being polar.

However acetic acid being most polar has the maximum hydrogen bonding.

Thus acetic acid has the strongest intermolecular forces of attraction.

A sample of gas has an initial pressure of 1.5 atm, an initial volume of 3.0 L, and an initial temperature of 293K. If the final
Nataliya [291]

Answer:

1.9 L

Explanation:

Step 1: Given data

  • Initial pressure (P₁): 1.5 atm
  • Initial volume (V₁): 3.0 L
  • Initial temperature (T₁): 293 K
  • Final pressure (P₂): 2.5 atm
  • Final volume (V₂): ?
  • Final temperature (T₂): 303 K

Step 2: Calculate the final volume of the gas

If we assume ideal behavior, we can calculate the final volume of the gas using the combined gas law.

P₁ × V₁ / T₁ = P₂ × V₂ / T₂

V₂ = P₁ × V₁ × T₂ / T₁ × P₂

V₂ = 1.5 atm × 3.0 L × 303 K / 293 K × 2.5 atm = 1.9 L

The pressure on a 200-milliliter sample of CO2(g) at
motikmotik

Answer:

A) 100 mL

Explanation:

At constant temperature and number of moles, Using Boyle's law  

{P_1}\times {V_1}={P_2}\times {V_2}

Given ,  

V₁ = 200 mL

V₂ = ?

P₁ = 60 kPa

P₂ = 120 kPa

Using above equation as:

{P_1}\times {V_1}={P_2}\times {V_2}

{60\ kPa}\times {200\ mL}={120\ kPa}\times {V_2}

{V_2}=\frac{{60}\times {200}}{120}\ mL

{V_2}=100\ mL
