Answer:
11.84 moles
Explanation:
We first balance the chemical equation
Both number of elements in the reactant side is equal to elements on the product side thus this equation is already balanced
Using mole ratio to find moles of 
1 mole of CoCl2 reacts with 1 mole of F2 to produce 1 mole of CoF2 and ! mole of Cl2
Mole CoCl2 = Mole CoF2 = 11.84 moles
Answer:
Cream butter and sugar. Beat in eggnog, baking soda and nutmeg. Gradually add flour and mix well. Cover and chill 1 hour. On a lightly floured surface, roll out half of the dough to 1/8-in. thickness. Using floured 3-1/2-in. cookie cutters, cut into desired shapes; place on ungreased baking sheets. Repeat with remaining dough.
Explanation:
eggnog crumble cookies they are so good
We can use the heat equation,
Q = mcΔT
where Q is the amount of energy transferred (J), m is the mass of the substance (kg), c is the specific heat (J g⁻¹ °C⁻¹) and ΔT is the temperature difference (°C).
Q = 11.2 kJ = 11200 J
m = <span>145 g
</span>c = ?
ΔT = (67 - 22) °C = 45 °C
By applying the formula,
11200 J = 145 g x c x 45 °C
c = 1.72 J g⁻¹ °C⁻¹
Hence, specific heat of benzene is 1.72 J g⁻¹ °C⁻¹.
