Answer:

Combustion

Explanation:

The reaction type is a combustion reaction;

Ethanol + oxygen gas → carbon dioxide + water

Now;

Ethanol is the fuel and oxygen gas rapidly combines with it to form carbon dioxide and water.

This process releases heat energy from chemical bonds.
Most hydrocarbons burn in excess air or oxygen to give carbon dioxide and water.

If ine mole of pennies were divided amung 250 million peoplein

Airida [17]

Answer:

$2.4088\times 10^{13}$ dollars each person will receive.

Explanation:

Number of people in which 1 mole of pennies is distributed = 250 million =

$1 million = 10^6$

250 million = $2.5\times 10^8$ persons

Number of pennies in 1 mole = $6.022\times 10^{23}$

Pennies per person:

$\frac{6.022\times 10^{23} pennies}{2.5\times 10^8 persons}=2.4088\times 10^{15} pennies/person$

1 penny = 0.01 $

$2.4088\times 10^{15} pennies/person=2.4088\times 10^{15}\times 0.01 \$/person=2.4088\times 10^{13} \$/person$

$2.4088\times 10^{13}$ dollars each person will receive.

Carbon monoxide (CO) reacts with hydrogen (H2) to form methane (CH4) and water (H2O).

Artemon [7]

Answer:

5.9x10^-2 M

Explanation:

Step 1:

Data obtained from the question. This includes the following:

Concentration of CO, [CO] = 0.30 M

Concentration of H2, [H2] = 0.10 M

Concentration of H2O, [H2O] = 0.020 M

Equilibrium constant, K = 3.90

Concentration of CH4, [CH4] =..?

Step 2:

The balanced equation for the reaction. This is given below:

CO(g) + 3H2(g) <=> CH4(g) + H2O(g)

Step 3:

Determination of the concentration of CH4.

The expression for equilibrium constant of the above equation is given below:

K = [CH4] [H2O] / [CO] [H2]^3

3.9 = [CH4] x 0.02/ 0.3 x (0.1)^3

Cross multiply to express in linear form

[CH4] x 0.02= 3.9 x 0.3 x (0.1)^3

Divide both side by 0.02

[CH4] = 3.9 x 0.3 x (0.1)^3 /0.02

[CH4] = 5.9x10^-2 M

Therefore, the equilibrium concentration of CH4 is 5.9x10^-2 M
