How do you do this
yaroslaw [1]

Answer:

The volume of basketball is  7216.5 cm³.

Explanation:

Given data:

Radius of ball = 12 cm

Volume of ball = ?

Solution:

We will apply the volume formula of sphere.

V = 4/3 ×π×r³

we know that,

π = 22/7

r = 12 cm

Now we will put the values in formula.

V = 4/3 × 3.14 × (12 cm)³

V =  4/3 × 3.14 ×1728 cm³

V = 7216.5  cm³

Thus, the volume of basketball is  7216.5  cm³.

How many moles of methane are produced when 85.1 moles of carbon dioxide gas react with excess hydrogen gas?
tino4ka555 [31]

Taking into account the reaction stoichiometry, 340.0 moles  of methane are produced when 85.1 moles of carbon dioxide gas react with excess hydrogen gas

<h3>Reaction stoichiometry</h3>

In first place, the balanced reaction is:

CO₂ + 4 H₄  → CH₄ + 2 H₂O

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

  • CO₂: 1 mole
  • H₄: 4 moles  
  • CH₄: 1 mole
  • H₂O: 2 moles

<h3>Moles of CH₄ formed</h3>

The following rule of three can be applied: if by reaction stoichiometry 1 mole of CO₂ form 4 moles of CH₄, 85.1 moles of CO₂ form how many moles of CH₄?

moles of CH_{4} =\frac{85.1 moles of CO_{2}x4 moles of CH_{4} }{1 moles of CO_{2}}

<u><em>moles of CH₄= 340.4 moles</em></u>

Then, 340.0 moles  of methane are produced when 85.1 moles of carbon dioxide gas react with excess hydrogen gas
