Answer:
The variation of the proportion of water
Explanation:
Forming oxygen by bubbling fluorine through water.
Single displacement is the type of chemical reaction
<h3>
Answer:</h3>
54 g
<h3>
Explanation:</h3>
- The reaction between carbon and oxygen gas is given by the equation;
C(s) + O₂(g) → CO₂(g)
We are given;
18 g of Carbon
72 g of Carbon dioxide
- We need to calculate the amount of oxygen needed for the reaction.
- From the law of conservation of mass in chemical equation, the mass of the reactants is equal to the mass of the product.
Therefore;
Mass of Oxygen gas + mass of the carbon = Mass of carbon dioxide
Therefore;
Mass of Oxygen gas = mass of carbon dioxide - mass of carbon
= 72 g - 18 g
= 54 g
Therefore, the mass of Oxygen needed would be 54 g
The average kinetic energy of a gas when the particles of the gas collide against each other at a constant temperature and volume will not changes.
<h3>What is average kinetic energy?</h3>
The product of half the mass of each gas molecule with the square of root mean square speed is the average kinetic energy of the molecules.
And this average kinetic energy is deirectly proportional to the absolute temperature of the system but in the given question temperature and volume of the gas is constant. So that there is no change in average kinetic energy of molecules when they collide.
Hence no change in the average kinetic energy of a gas takes place.
