Answer:
The product expected is 10CO2 + 4H2O
Answer: 
Explanation:
Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.
A more reactive element is one which can easily lose or gain electrons as compared to the other element.
As Magnesium is more reactive than tin, it can easily displace tin from its salt solution
and form magnesium chloride and tin in elemental form.
The balanced chemical equation is:

Answer: KI, LiBr, MgS,GaN
Explanation:
Ionic sizes are the deciding factor in lattice energy. The smaller the ion, the higher the lattice energy. Since K+> Li+ and I- is larger than Br-, LiBr will have a higher lattice energy. The size of the sulphide ion is much smaller than the nitride ion but the Gallium is much smaller due to lanthanide contraction hence the answer.
Answer: students are the dependent variable and the cartoon are the independent variable
Explanation: because the cartoon are being the same ever and the opinion of the students is what changes
