WHAT MASS OF WATER WILL BE PRODUCED FROM 2.70 MOLES OF CA(OH)2 REACTING WITH HCI
Keith_Richards [23]

<u>Answer:</u> The mass of water produced in the reaction is 97.2 grams

<u>Explanation:</u>

We are given:

Moles of calcium hydroxide = 2.70 moles

The chemical equation for the reaction of calcium hydroxide and HCl follows:

Ca(OH)_2+HCl\rightarrow CaCl_2+2H_2O

By Stoichiometry of the reaction:

1 mole of calcium hydroxide produces 2 moles of water

So, 2.70 moles of calcium hydroxide will produce = \frac{2}{1}\times 2.70=5.40mol of HCl

To calculate mass for given number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Molar mass of water = 18 g/mol

Moles of water = 5.40 moles

Putting values in above equation, we get:

5.40mol=\frac{\text{Mass of water}}{18g/mol}\\\\\text{Mass of water}=(5.40mol\times 18g/mol)=97.2g

Hence, the mass of water produced in the reaction is 97.2 grams

If water is present during the grignard formation, what possible byproduct may form?
Zanzabum

Important of Grignard Reagent :

Grignard reactions are main due to their capacity to form carbon-carbon bonds. Grignard reagents are powerful bases and will react with protic compounds which makes them exceptionally valuable implement for organic synthesis.

Grignard reagents react fastly with acidic hydrogen atoms in molecules such as alcohols and water. When a Grignard reagent reacts with water, a proton return back halogen, and the product is an alkane. The Grignard reagent therefore provides a trace for transforming a haloalkane to an alkane in two steps.

When reacted with water,

RMgX + H2O -------> R-H + MgOH X

R ---- Alkyl Group

X --- Halogen

Which statement best describes the effect of color on energy absorption and reflection? 1. Light colors reflect more and absorb
fredd [130]
The statement which best described the effect of color on energy absorption and reflection is this: LIGHT COLORS REFLECT MORE AND ABSORB LESS THAN DARK COLORS. Black color absorbs all incident radiations while white color reflects all incident radiations; all other colors fall in the midst of these two colors.
