Answer:
more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.
D should be the answer since there are tons of moons in our solor systtem
Ion is an atom or molecule with a net electric charge due to loss or gain of one or more electrons.
Answer:
111.68 g
Explanation:
Given data:
Mass of HgS needed = ?
Mass of CaS produced = 26.0 g
Solution:
Chemical equation;
4HgS + 4CaO → 4Hg + 3CaS + CaSO₄
Number of moles of CaS:
Number of moles = mass/molar mass
Number of moles = 26 g/ 72.143 g/mol
Number of moles = 0.36 mol
Now we will compare the moles of HgS with CaS.
CaS : HgS
3 : 4
0.36 : 4/3×0.36 = 0.48 mol
Mass of HgS:
Mass = number of moles × molar mass
Mass = 0.48 mol × 232.66 g/mol
Mass = 111.68 g
Answer:
96.3%
Explanation:
Data obtained from the question include:
Theoretical yield = 54g
Actual yield = 52g
Percentage yield =..?
The percentage yield can be obtain as follow:
Percentage yield = Actual yield /Theoretical yield x 100
Percentage yield = 52/54 x 100
Percentage yield = 96.3%
Therefore, the percentage yield of the reaction is 96.3%
