Answer:
See below
Explanation:
A chemist preforms the following: Neutralizing nitric acid (HNO3) with soda ash (Na2CO3). This reaction will then create sodium nitrate and carbonic acid, which will then decompose into water (H20)
Boyle’s Law I’m pretty sure
First of all, you have to write a balance equation for the reaction. The balanced equation for the reaction is:
CaCO3 + 2CH3COOH = [CH3COO]2Ca +CO2 + H20
Next, find the mass of the shell.
For an average egg, the mass is 0.05 * 50 = 2.5 g.
To convert this mass to moles, we have: 2.5/100 = 0.025 Moles. This is the mole of calcium carbonate.
To calculate the mole of ethanolic acid, we have: 50 * 0.001 * 2 = 0.1. This value is for 2 molecules, therefore for one molecule, we have: 0.1/2 = 0.05.
From the equation of reaction, one mole of calcium carbonate is required to neutralize two moles of ethanolic acid.
Thus, 0.05/0.025 = 2. This imply that two complete egg shells will be needed to neutralize 50cm of ethanolic acid.
Answer:
Repulsion Forces create the bent triatomic shape of a water molecule.
Matter is anything that has mass and takes up space.
Hope this helps!! (:
