Calcium Hydroxide (Ca(OH)2) reacts with the Carbon Dioxide (CO2) present in the Air to form Calcium Carbonate (CaCO3) and Water (H2O).
The equation looks something like this -->
Ca(OH)2 + CO2 = CaCO3 + H2O
Answer: 64.1 ml of concentrated is taken and (250-64.4)= 185.6 ml f water is added to make 250.00 mL of 3.00 M HCl .
Explanation:
Given : 36 g of is dissolved in 100 g of solution.
Density of solution = 1.18 g/ml
Thus volume of solution =
where,
n= moles of solute
= volume of solution
According to the dilution law,
where,
= molarity of stock solution = 11.7M
= volume of stock solution = V ml
= molarity of diluted solution = 3.00 M
= volume of diluted solution = 250.0 ml
Thus 64.1 ml of stock is taken and (250-64.4)= 185.6 ml of water is added to make 250.00 mL of 3.00 M HCl .
<span>4.200 calories. The formula is rise in heat (H) = the specific heat capacity (c) * rise in heat in degrees Fahrenheit (T) and volume of liquid (m) . H= cTm. Water, the typical comparison, has a specific heat capacity of 1. So to raise the Fahrenheit temperature of 105 grams of water 40 degrees, you multiply 105 * 40 * 1 = 4,200.</span>
