One mole of a substance is defined by Avogadro as consisting of 6.022 x 1023 atoms. This is Avogadro's number. To calculate the number of atoms in two moles of sodium, use dimensional analysis. 2.0 moles Na x 6.022⋅1023g1mol=1.20⋅1024 atoms of Na

In a coffee-cup calorimeter, 100.0 g of H2O and 100.0 mL of 1M HCl are mixed. The HCl had an initial temperature of 44.6 C and t

Hatshy [7]

Answer:

Exothermic reaction for the HCl, endothermic reaction for the water

$2803.28\ \text{J}$

Explanation:

Heat was lost by HCl as its temperature lowered, so it was an exothermic reaction for the HCL.

Heat was gained by water as its temperature increased, so it was an endothermic reaction for the water.

m = Mass of water = 100 g

c = Specific heat of water = $4184\ \text{J/kg}^{\circ}\text{C}$

$\Delta T$ = Change in temperature of water = $(31.3-24.6)^{\circ}\text{C}$

Heat is given by

$Q=mc\Delta T\\ =0.1\times 4184\times (31.3-24.6)\\ =2803.28\ \text{J}$

Heat gained by water is $2803.28\ \text{J}$ .

steposvetlana [31]

Answer:

The system will change its concentration to shift to a new equilibrium position.

Explanation:

For example in the Haber Process

N2 + 3H2 ⇄ 2NH3

If the pressure is increased the process will move to the right - to have more NH3 and less of the nitrogen and hydrogen.
