I believe the mass of the product will be 400 grams. This is because according to the law of conservation of mass, mass is neither created nor destroyed . In a closed system, the mass of reactants is equal to mass of products. Therefore, since the total mass of the reactants is 400 grams then the mass of the products will still be 400 grams
OR
200
The best and most correct answer among the choices provided by your question is the fourth choice which is "<span>Heat moves through conduction, convection, and radiation."
</span>Heat transfer<span> is the exchange of thermal energy between physical systems. The rate of </span>heat transfer<span> is dependent on the temperatures of the systems and the properties of the intervening medium through which the</span>heat<span> is </span>transferred<span>. The three fundamental modes of </span>heat transfer<span> are conduction, convection and radiation.</span>

Hello my friend,
No. of valence electron determine the reaction between elements.
hope it helps☺☺
Answer:
C₇ H₁₆ + 11O₂ → 7CO₂ + 8H₂O
Explanation:
Given equation
C₇ H₁₆ + O₂ → CO₂ + H₂O
To solve this problem,
We use a mathematical approach to balance the equation:
aC₇ H₁₆ + bO₂ → cCO₂ + dH₂O
Conserving C; 7a = c
H ; 16a = 2d
O: 2b = 2c + d
Let a = 1
c = 7
d = 8
b = 11
Now insert the parameters and solve;
C₇ H₁₆ + 11O₂ → 7CO₂ + 8H₂O
