Answer:
43.76 g = 0.04376 Kg
Explanation:
The equation of the reaction is given as;
H2 + Cl2 --> 2HCl
From the equation;
1 mol of Cl2 produces 2 mol of HCl
Converting to mass;
Mass = Number of mol * Molar mass
Cl2;
Mass = 1 mol * 70.906 g/mol = 70.906 g
HCl;
Mass = 2 mol * 36.458 g/mol = 72.916 g
This means;
70.906 g of Cl2 produces 72.916 g of HCl
x g of Cl2 would produce 45g of HCl
70.906 = 72.916
x = 45
x = 45 * 70.906 / 72.916
x = 43.76g
Answer:
It would take less time, because having a lower temperature of latent heat means that at a lower temperature it merges, therefore the closer it will be to the temperature of solification which is 0 degrees Celsius or Celsius ... It is then that it would solidify in less time than water
Explanation:
By acting and having all the same properties as water except for latent heat, it considers that the solidification temperature is 0 degrees Celsius like water.
We are given with
Cobalt phosphate - CoPO4
We are asked for the net ionic equation for the phosphate dissolving in H3O+
The net ionic equation is
CoPO4 (s) + H3O+ (aq) -----> HPO42- (aq) + Co3+ (aq) + H2O *(l)
Answer:
+3
Explanation:
Chlorine is anion with a -1 charge. But they are three chlorine atoms.
-1 * 3 = -3
So they have a -3 charge.
So to balance the compound, the nickel has to be a cation with a +3 charge.
-3 + 3 = 0
Furthermore, a chemical bond always has a 0 charge. Remember that.
Hope it helped! Rate my answer a 5 star if correct.
