The three steps involve;
Step 1: Separation/expansion of the solute particles
Step 2: Separation/expansion of the solvent particles
Step 3; Combining the solute and solvent particles
The first two steps are usually endothermic. Step 3, nonetheless, can be either exothermic or endothermic and is significant in determining whether the dissolving process will be endothermic or exothermic.
Answer:
0.01504 mol/dm3
Explanation:
Calcium Hydroxide - Ca(OH)2
Hydrochloric acid - HCl
The reaction between both is given as;
2HCl + Ca(OH)2 --> CaCl2 + 2H2O
2 : 1
The relationship between the concentration and volume is given as;
CaVa / CbVb = na / nb
where a = acid (HCl) and b = base Ca(OH)2
Inserting the values;
0.04 * 18.8 / (Cb * 25) = 2 / 1
0.752 / 25Cb = 2
Cb = 0.752 / 50 = 0.01504
Answer:
Your notation is a bit confusing, let me write it more clearly.
Explanation:
( Temperature in °F − 32) × 5/9 = Temperature in °C
Explanation:
The gas that would behave least ideally is CO
Answer: 14.0 moles of carbon.
Explanation: Using the Avogadro's number,
6.02 x 10^23 atoms -----> 1 mole of carbon .
8.43 x 10^24 atoms ----> 8.43 x 10^24/ 6.02 x 10^23 = 14.0moles of carbon.
