Moles of Sulfuric acid needed to react completely : 3.2
<h3>Further explanation</h3>
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction (balanced)
<em>H₂SO₄ (aq) + 2 LiOH (aq) ⇒ Li₂SO₄ (aq) + 2 H₂O (l)</em>
moles of LiOH = 6.4
From equation, mol ratio of H₂SO₄ : LiOH = 1 : 2, so mol H₂SO₄ :
Answer:
Nitrogen
It has the least number of protons in the group hence making it smaller
Explanation:
According to periodic table, electronegativity increases across the period and decreases down the group.
Electronegativity is the tendency of an element to accept electrons towards itself.
In this group of elements, nitrogen has the highest electronegativity because it has the least number of protons in the group. Increase in the number of protons decreases an elements electro negative value.
The least electronegative element in that group is Antimony (Sb).
Electronegativity increases across the period and decreases down the group while electropositivity decreases across the period and increases down the group.
Hi my dear friend,
The statement that explain how ATP and its phosphate groups are related to energy used in plant process is that ADP gains a phosphate to create ATP, which stores energy for making sugars. These packets of energy in the form of ATP are then broken down to release energy and use that energy in synthesis of glucose.
~Thank you
<u>Given:</u>
Volume of HCl = 150 ml
Molarity of HCl = 0.10 M
<u>To determine:</u>
The # moles of HCl
<u>Explanation:</u>
The molarity of a solution is the number of moles of a solute dissolved in a given volume
In this case:
Molarity of HCl = moles of HCl/volume of the solution
moles of HCl = Molarity * volume = 0.10 moles.L-1 * 0.150 L = 0.015 moles
Ans: A)
Moles of HCl is 0.015
