Answer:reaction, or reactants becoming products: A + B →. C + D reactants products ... CaCl2 has two Cl's because Ca is +2 charged so we need two –1 ... Due to the Law of Conservation, the number of atoms (and the mass) of each ... This is a balanced equation – same number of H and O atoms on both sides of the arrow.

Answer:

This equation is not balanced because your mass of the products is not equal to the mass of the reactants. So the correct option is no because the law of conservation of mass is not being followed. The hydrogen and chlorine atoms have different numbers of atoms in the reactants and products.

Explanation:

This is because on your reactant you have 2 Hydrogen atoms while on your product side you have four because the coefficient of 2 and the H2 multiply and make four in total. Also, on the reactant side, you have 2 chlorine and on the product side, you have 4 chlorine atoms.

A simple way to look at this would by doing this:

Equation: 2Zn + 2HCl ----- 2H2 + 2ZnCl2

So on the reactant side, you have 2 zinc atoms, 2 hydrogen atoms and 2 chlorine atoms while on the product side, you have 4 hydrogen atoms, 2 zinc atoms and 4 chlorine atoms.

Hope that helps!!

Ann [662]

Answer: Young children

Explanation: Resistance to food borne illnesses develops through exposure to small amounts of food borne pathogens. The longer the exposure, the greater the buildup of immunity. Young children are more likely to succumb to food borne illnesses due to lack of exposure to pathogens, and resultant lack of resistance to them.
