1) Conservation of Matter states that the reactants have to equal the products.

2) Products and reactants in a balanced chemical reaction have the same number of atoms of each element.

3) Three (3) atoms of carbon would need to be represented.

Explanation:Number of atoms on the left and on the right side of the balanced chemical reaction is the same, for example: Mg + 2HCl → H₂ + MgCl₂. There are two hydrogen atoms, two chlorine atoms and one magnesium atom on both side of chemical reaction.

i'm pretty sure it is letter c.) car

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
