Matter is predominantly know to exist in three states-
-Solid
-Liquid
-Gas
The three states can be interconverted at appropriate temperature and pressure conditions. Each state exhibits unique properties which are influenced by the intermolecular forces that hold the atoms together in these states.
Ans: Thus, Every time matter changes from a liquid to a gas, the matter also experiences a change in the <u>state (or phase)</u>
I would say B.HS(aq)+NiSO4(aq)
The balanced reaction is: 2Mo+3O2>2MoO3
The volume of H₃PO₄ : 13.33 ml
<h3>Further explanation</h3>
Given
0.003 M Phosphoric acid-H₃PO₄
40 ml of 0.00150 M Calcium hydroxide-Ca(OH)₂
Required
Volume of H₃PO₄
Solution
Acid-base titration formula
Ma. Va. na = Mb. Vb. nb
Ma, Mb = acid base concentration
Va, Vb = acid base volume
na, nb = acid base valence (amount of H⁺/OH⁻)
H₃PO₄⇒3H⁺ + PO₄³⁻ ⇒ 3 H⁺ = valence = 3
Ca(OH)₂⇒Ca²⁺ + 2OH⁻⇒ 2 OH⁻ = valence = 2
Input the value :
a = H₃PO₄, b = Ca(OH)₂
0.003 x Va x 3 = 0.0015 x 40 x 2
Va = 13.33 ml
Answer:
Rn
Explanation:
Rn is the symbol for radon with the atomic number of 86
