How many reactants does the following equation have h2o → h2 + o2
a)1
b)2
c)3

Answer;

A) 1 (one)

Explanation;Reactants are elements and/or compounds that are changed into other substances called products.The reactants are what you start with and the products are the result. In the chemical reaction equation the reactants are on the left and the products are on the right.In this case; H2O is the only reactant, while H2 and O2 are the products.

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
