HCl + NaOH --> NaCl + H2O.
In layman terms, salt and water are the products of this chemical reaction.
From,
RAM=element×its relative abudance/total abudance
=((107×13)+(12×109))/25
The answer is=107.96
There are 1.078 x 10²³ molecules
<h3>Further explanation</h3>
Given
4 dm³ = 4 L Nitrogen gas
Required
Number of molecules
Solution
Assumptions on STP (1 atm, 273 K), 1 mol gas = 22.4 L, so for 4 L :
mol = 4 : 22.4
mol = 0.179
1 mol = 6.02 x 10²³ particles(molecules, atoms)
For 0.179 :
= 0.179 x 6.02 x 10²³
= 1.078 x 10²³
Answer:
Chromatography is used to separate mixtures of substances into their components.They all have a stationary phase (a solid, or a liquid supported on a solid)
Explanation:
it's where the things stay still until the mobile phase moves through and takes the components
