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.

3.75 is the correct answer to your question mate
Answer: At the bottom if their is answer chocies then D
Explanation: Hope this helps ;)
The force is 5100 N which is accelerating a Ford Mustang. The mass of the car is 1700 kg.
<h3>What is force?</h3>
A force is an influence that can alter an object's motion. A force can modify the velocity of a mass item. Force is calculated in Newton.
In physics, mass is a quantitative measure of inertia, which is a fundamental property of all matter. Mass is measured in kilograms and grams.
The force is given as 5100 N
The acceleration is 3 m/s
The mass is to be calculated
F = ma
m = F / a
m = 5100 / 3
m = 1700 kg
Therefore, the mass of the car is 1700 kg.
