Answer:
The mass of 4.5 moles of Cu(NO3)2 is 843.55g
Explanation:
Mass = moles x Molar mass
Mass = 4.50(187.55)
= 843.97g
As i am reading the question, I notice they give two concentrations (M), one volume (L), and they are asking for another volume. this is a hint that you need to use the following formula
C1V1 = C2V2 (note: C stands for concentration)
C1= 2.9 M
V1= ?
C2= 1.1 M
V2= 2.3 L
now let's plug in the numbers
( 2.9 x V1)= (1.1 X 2.3)
V1= 0.87 Liters

See explanation
Explanation:
When sodamide reacts with methanol, the following equilibrium is set up;
CH3OH(aq) + NH2-(aq) ⇄ CH3O-(aq) + NH3(aq)
In the reaction, the sodamide acts as a base that abstracts a proton from methanol to yield the conjugate base of methanol which is the methoxide ion.
The forward reaction is favoured at equilibrium.
Answer:
blood travels to the pulmonary arteries
Explanation:
This is called the pulmonary circulation. From your pulmonic valve, blood travels to the pulmonary arteries and eventually to tiny capillary vessels in the lungs.
