Answer:
False
Explanation:
The correnct chain is labeled Maize, Goat, Man.
Explanation:
Equation of reaction:
CO + 2H₂ ⇒ CH₃OH + energy
a. An increase in pressure:
A change in pressure affects only equilibrium involving a gas or gases. Le Chatelier's principle can be used to predict the direction of displacement.
An increase in pressure on an equilibrium system will shift the position of equilibrium to the side having smaller volume and vice-versa
CO + 2H₂ ⇒ CH₃OH + energy
3 moles 1 moles
An increase in pressure will favor the forward reaction to be favored.
b. Addition of H₂:
An in concentration of a specie favors the direction that uses up that specie and lowers its concentration.
Addition of hydrogen gas increases the concentration of amount of substances reacting.
To annul the effect of the reactant, more the product is given. The equilibrium shifts in the forward direction.

0.32 moles
You just do 14/ 44.01 (the atomic mass of carbon + oxygen's atomic massX2)
Answer:
1.552 moles
Explanation:
First, we'll begin by writing a balanced equation for the reaction showing how C8H18 is burn in air to produce CO2.
This is illustrated below:
2C8H18 + 25O2 -> 16CO2 + 18H2O
Next, let us calculate the number of mole of C8H18 present in 22.1g of C8H18. This is illustrated below:
Molar Mass of C8H18 = (12x8) + (18x1) = 96 + 18 = 114g/mol
Mass of C8H18 = 22.1g
Mole of C8H18 =..?
Number of mole = Mass /Molar Mass
Mole of C8H18 = 22.1/144
Mole of C8H18 = 0.194 mole
From the balanced equation above,
2 moles of C8H18 produced 16 moles of CO2.
Therefore, 0.194 mole of C8H18 will produce = (0.194x16)/2 = 1.552 moles of CO2.
Therefore, 1.552 moles of CO2 are emitted into the atmosphere when 22.1 g C8H18 is burned
It would weigh more: the more mass an object has the more weight is added
