From the graph given , energy of reactant = 0

b )

energy of product = -15 kJ

c )

ΔH = energy of product - energy of reactant

= -15 - 0 = - 15 kJ

ΔH is negative so reaction is exothermic .

d ) Activation energy = 25 - 0 = 25 kJ .

1. The mass of 6.45 x 1022 atoms C

Fed [463]

Answer:

$\large \boxed{\text{1.29 g}}$

Explanation:

We must convert atoms of C to moles of C and then to grams of C.

1. Convert atoms to moles

$\text{Moles of C} = 6.45 \times10^{22}\text{ atoms C} \times \dfrac{\text{1 mol C}}{6.022 \times\ 10^{23} \text{ atoms C}} = \text{0.1071 mol C}$

2. Convert moles to grams

$\text{Mass of C} = \text{0.1071 mol C} \times \dfrac{\text{12.01 g C}}{\text{1 mol C}} = \text{1.29 g C}\\\text{The mass of C is $\large \boxed{\textbf{1.29 g}}$}$
