Answer : The concentration of solution is, 0.45 M
Solution :
The given balanced reaction is,
The moles ratio of and is, 1 : 1 that means 1 mole of HCl neutralizes by the 1 mole of ammonia.
According to the neutralization law,
where,
= molarity or concentration of solution = ?
= volume of solution = 25 ml
= molarity of concentration HCl solution = 0.25 M
= volume of HCl solution = 45 ml
Now put all the given values in the above law, we get the concentration of solution.
Therefore, the concentration of solution is, 0.45 M

is available in excess?
Given 97.0 g of propane (C3H8), about 6.6 moles of CO2 will be produced according to the balanced chemical equation for the combustion of propane.
The question asks how many moles of CO2 will be produced from 97.0 g of C3H8, assuming O2 is available in excess.
The balanced chemical equation for the combustion of propane (C3H8) is C3H8 + 5O2 → 3CO2 + 4H2O. This tells us that one mole of propane produces three moles of CO2.
First, we need to find the moles of propane. The molar mass of propane is approximately 44.09 g/mole. So, 97.0 g of propane corresponds to approximately 2.2 moles. Therefore, 2.2 moles of propane produce 2.2 * 3 = 6.6 moles of CO2.

Answer:
K < Fe < Br < Kr
Explanation:
Given chemical elements;
Potassium
Iron
Bromine
Krypton
Problem; arrange in order of increasing electronegativity
Solution:
The electronegativity of an element measures the relative tendency with which the atoms of the element attracts valence electrons in the chemical bond.
To solve this problem, we are going to use values of electronegativity from the Pauling's electronegativity table of elements;
For;
Potassium = 0.8
Iron = 1.83
Bromine = 2.8
Krypton = 3.0
So;
K < Fe < Br < Kr
