The excess reactant in the combustion of 211 g of methane in an open atmosphere is oxygen, O₂

<h3>What is a combustion reaction? </h3>

A combustion reaction is a reaction in which a substance burns in air (oxygen) to produce carbon dioxide and water.

<h3>Combustion of methane </h3>

Methane combust in air (oxygen) to produce carbon dioxide and water according to the following equation:

CH₄ + 2O₂ —> CO₂ + 2H₂O

From the question given above, we were told that 211 g of methane combust in an open atmosphere. This simply means that the amount of oxygen will be very high.

Therefore, we can conclude that oxygen will be the excess reactant since the reaction is carried out in an open atmosphere.

Magnolia company’s high and low level of activity last year was 60,000 units of product produced in april and 20,000 units produ

nlexa [21]

The total maintenance cost for a month in which production is expected to be 45,000 units is; TMC = $80,000

<h3>What is the Total Maintenance Cost?</h3>

The computation of the fixed cost and the variable cost per hour by using high low method is shown as follows;

Variable cost per hour = (High Machine maintenance costs - low Machine maintenance costs) ÷ (High activity level - low activity level)

Plugging in the relevant values gives;

Variable cost per hour = ($104,000 - $40,000) ÷ (60,000 units - 20,000 units)

Variable cost per hour = $1.6

The variable cost = High activity level × per unit variable cost

Variable cost = 60,000 units × 1.6

Variable Cost = $96,000

Fixed cost = Total cost - variable cost

Fixed Cost = $104,000 - $96,000

Fixed Cost = $8,000

For 45,000 units, total maintenance cost is;

Total Maintenance Cost = Number of units × per unit variable cost + Fixed cost

TMC = (45,000 units × $1.6) + $8,000

TMC = $80,000
