the answer is B. 2
because there is 2 iron on the right side so you need another two on the left side to balance it out
Answer:
chemical
Explanation:
The trapped carbon dioxide makes the dough rise, and the alcohol evaporates during the baking process. This is an irreversible chemical change, because by consuming the sugar, the yeast has created new substances
I think it’s A for the first one and C for the second one
Answer: Formation of hydrogen iodide will occur.
Explanation:
When molecule of hydrogen gas 
and molecule of iodine gas 
collide with proper orientation and with sufficient amount of energy. This collision of the two different molecules of gases will result in the formation of hydrogen iodide.
The balanced chemical equation of the reaction will written as:
Answer:
A. m and n are independent from the molar coefficients of the reactants in the balanced chemical equation.
B. m and n must be determined by experiment.
Explanation:
rate = k[H2O2]^m × [I-]^n
The Order of Reaction refers to the power dependence of the rate on the concentration of each reactant.
Either the differential rate law or the integrated rate law can be used to determine the reaction order of reactants from experimental data.
