ah, 40.3 grams - 16 grams = 24.3 grams, not 24 grams

I can not help with the others, do not see the pictures.

To solve the first question, you can use stoichiometry and the Law of Conservation of Mass. Here's how:

1) Write and balance the chemical equation for the reaction:
2 Mg + O₂ → 2 MgO

2) Calculate the molar masses of each substance:
Mg = 24.31 g/mol
O = 16.00 g/mol

3) Convert the given masses to moles:
Mg = 16.0 g / 24.31 g/mol ≈ 0.658 mol
O₂ = 40.3 g / 32.00 g/mol ≈ 1.259 mol

4) Use the mole ratio from the balanced equation to determine the moles of magnesium reacting:
From the balanced equation, 2 moles of Mg reacts with 1 mole of O₂.
So, 1.259 mol O₂ × (2 mol Mg / 1 mol O₂) = 2.518 mol Mg

5) Convert the moles of magnesium to grams:
Mass of Mg = moles of Mg × molar mass of Mg
Mass of Mg = 2.518 mol × 24.31 g/mol ≈ 61.26 g

Therefore, approximately 61.26 grams of magnesium will react with 16.0 grams of oxygen to produce 40.3 grams of magnesium oxide.

For the second question, the chemical equation that shows no atoms were lost during a chemical reaction is:
2H + 2F → 4HF

This equation demonstrates that the number of atoms of each element is balanced on both sides of the equation.

Regarding the third question, if the red arrows indicate the movement of carbon, it is likely representing the process of decay. Decay is the natural process of decomposition of organic matter, such as dead plants and animals, where carbon is released back into the environment.

Lastly, there is no given option for adding another image of combustion in the provided question.
