Answer:
75 ml of 0.1M base neutralizes 25 ml of 0.1M acid, which means the acid has 0.3 moles/L of H ion
but that means each molecule of the acid has 3 times as many H ions aH ions in a molecule of NaOH
which means the formula for the acid must be H3A and
the value of x in
HxA is 3
Explanation:
75ml of a solutipn of 0.1moL l-1 NaOH neutralises 25ml of a solution of an acid. The formula of the acid is HxA and the concentration of the acid is 0.1mol l-1. What is the value of x?
the concentration of both the and the base are the same at 0.1M
the base...NaOH has 0.1 moles/L of OH ion
75 ml of 0.1M base neutralizes 25 ml of 0.1M acid, which means the acid has 0.3 moles/L of H ion
but that means each molecule of the acid has 3 times as many H ions aH ions in a molecule of NaOH
which means the formula for the acid must be H3A and the value of x in
HxA is 3
Explanation:
It's a triple bond for nitrogen,double bond for oxygen(just saying)
Answer:
Option A,+4
Explanation:
Oxidation state of any element is the sum of oxidation of all elements =0
Here we need to find oxidation no of carbon and consider oxidation no of carbon as X and oxidation number of oxygen is -2
Then X+2(-2)=0 (since 2 oxygen atoms are there in CO2 )
X-4=0
X=+4
I really cant show any work but it's 0.00043045
Answer:plz brainly me;)
Your answer is "A" Conductors
Nonmetals include common gasses that are found in the atmosphere, such as nitrogen and oxygen, as well as sulfur (S) and carbon too. Nonmetals are usually not good conductors of heat and electricity.
