Answer:Pressure of NH3 increases at the rate of 160torr/hr
Explanation:
According to the equation below
N2H4 (g) + H2 (g) ==> 2 NH3 (g)
It shows that 1mol of N2H4 will gives 2mol of NH3
Therefore, if the partial pressure rate of N2H4 is 80torr/hr, the partial pressure of NH3 increases by 2×80=160torr/hr
They have a positive charge.
Reaction type : Double-Replacement reactions
<h3>Further explanation</h3>
Given
Reaction
MgCl2 +
Li2CO3 →
MgCO3 +
LiCl
Required
Balanced equation
Reaction type
Solution
Balanced equation
Li2CO3 (s) + MgCl2 (aq) → MgCO3 (s) + 2 LiCl (aq)
Double-Replacement reactions. Happens if there is an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product
To predict whether this reaction can occur or not is one of them, the precipitation reaction.
MgCO3 is a precipitation compound
