Explanation:

34.2g of C12H22O11 is dissolved in 180g of H20.

Molar mass of sucrose = 342g/mol

Moles of sucrose = 342 / 34.2 = 10 mol.

Molar mass of water = 18g/mol

Moles of water = 180 / 18 = 10 mol.

For hydrogen atoms, there are 22 * 10 in sucrose and 2 * 10 in water, which gives a total of 240.

For oxygen atoms, there are 11 * 10 in sucrose and 1 * 10 in water, which gives a total of 120.

Which of the reactions are exothermic?
Nutka1998 [239]

Answer:

Reaction A, B, E and F are exothermic reactions.

Explanation:

Exothermic reactions are defined as the reactions in which energy of reactants is more than the energy of the products. In these reactions, energy is released by the system.

The total enthalpy of the reaction (\Delta H) comes out to be negative.

Endothermic reactions are defined as the reactions in which energy of products is more than the energy of the reactants. In these reactions, energy is absorbed by the system.

The total enthalpy of the reaction (\Delta H) comes out to be positive.

So, from the given option reaction which are exothermic are with negative value (\Delta H) that enthalpy of reaction and those are:

1) 2Mg(s) + O_2( g )\rightarrow 2MgO (s),ΔH = -1203 kJ/mol

2)NH_3 (g) + HCl (g)\rightarrow NH_4Cl (s),ΔH =-176 kJ/mol

3) C(graphite) + O_2 (g)\rightarrow CO_2 (g),ΔH = -393.5 kJ/mol

4) CH_4 (g) + 2O2 (g)\rightarrow CO_2 (g) + 2H_2O (l),ΔH =-891 kJ/mol

How do I do scientific notation
lina2011 [118]
1. First, move the decimal place until you have a number between 1 and 10. If you keep moving the decimal point to the right in 0.0000073 you will get 7.3.
2. Next, count how many places you moved the decimal point.
