Answer:sugar
Explanation:it is a homogeneous mixture
Density = mass/ volume
mass= 9.6 g
Volume of the object = 13.2-10.0 =3.2 ml=3.2 cm³
1ml =1 cm³
D=9.6g/3.2 cm³ = 3.0 g/cm³

Answer:
A balanced chemical equation must always include coefficients on every reactant and product.
Explanation:
<u>A balanced chemical equation does not need to include coefficients on every reactant and product.</u>
For example, below is a balanced chemical equation in which the reactants and the products have no coefficients whatsoever:
NaOH(aq) + HCl (aq) -----> NaCl (s) + H2O (l)
<em>Of course, a properly written chemical equation must include the states of matter of all the substances in the reaction and the number of atoms of each element must balance both in the reactant and product sides of the equation. Generally, a balanced chemical equation must obey the law of conservation of matter which opines that matter can neither be created nor destroyed but can only be converted from one form to another. </em>
Hence, that a balanced chemical equation must always include coefficients on every reactant and product is not true.
