The mass of A needed in a mixture : 15.625 g
<h3>Further explanation</h3>
Given
A mixture of A and B
Ratio A : B = 1 : 8
mass b = 125 g
Required
The mass of A
Solution
Proust states <em>the Comparative Law</em> that compounds are formed from elements with the same Mass Comparison so that compounds have a constant composition of elements
Mass of A (from the mass of B):
= 1/8 x 125 g
= 15.625 g
They are changes in bonding energy between the molecules. ... Immediately after the molecular bonds in the ice are broken the molecules are moving (vibrating) at the same average speed as before, so their average kinetic energy remains the same, and, thus, their Kelvin temperature remains the same."
The ways in which ammonia can be identified is mentioned in below pointers.
<h3>What is Ammonia ?</h3>
Ammonia is a compound of nitrogen and hydrogen with the formula NH3.
A stable binary hydride, and the simplest pnictogen hydride.
Ammonia is a colourless gas with a distinct pungent smell.
Biologically, it is a common nitrogenous waste,
Three ways in which ammonia gas can be identified is:
- It has a sharp characteristic odor.
- When a glass rod dipped in HCl is brought in contact with the gas white color fumes of ammonium chloride are formed.
- It turns moist red litmus blue, moist turmeric paper brown, and phenolphthalein solution pink.
