Grams of Chromium(III) nitrate produced : 268.95 g
<h3>Further explanation</h3>
Given
0.85 moles of Lead(IV) nitrate
Required
grams of Chromium(III) nitrate
Solution
Reaction
Balanced equation :
<em>2Cr₂ + 3Pb(NO₃)₄ ⇒ 4Cr(NO₃)₃ + 3Pb </em>
From the equation, mol ratio of Pb(NO₃)₄ : Cr(NO₃)₃ = 3 : 4, so mol Cr(NO₃)₃
mol Cr(NO₃)₃ =
Mass of Chromium(III) nitrate (MW=238.0108 g/mol) :
mass = mol x MW
mass = 1.13 x 238.0108
mass = 268.95 g
Answer:
All the above
Explanation:
A. Electrical current conduction
Aqueous solutions of both strong and weak acids will conduct an electric current. Weak acids are poorer conductors because they produce fewer ions.
B. Reaction with magnesium
Both strong and weak acids will react with magnesium, although weak acids will react more slowly.
C. pH paper test
Both strong and weak acids will give a colour with pH test paper, although the colours will probably be different.
D. Litmus paper test
Both strong and weak acids will turn blue litmus red.
Newton's third law of motion states that for every action force, there is an equal and opposite reaction force so that means that the wall is pushing you with the same amount of force that you put on it.
