A large amount of heat comes out as E= m c^2
Answer:
0.03
Explanation:
22.8 g Ba(OH)2 (1 mol Ba (OH)2/ 171.34 g) = 0.133 mol Ba (OH)2
77.2 g H2O (1 mol H2O/18 g) = 4.29 mol H2O
X= molar fraction= mol Ba(OH)2/ mol total
X= 0.133/ (0.133+4.29) = 0.03
Depends on where the object is. On earth, moon , or somewhere without any other mass (theoretically). I think you mean how much does weigh on earth. So, the average gravitational acceleration on earth is : 9.83 m/s^2 To find out how much an object weighs, this is the formula : G=m.g where m is mass of the object g is the gravitational acceleration and G is weight. So, G = 10.9,83 = 98,3 N is the answer.
Answer:
will be not soluble in water
Explanation:
LiOH is a strong base. Hence it gets completely dissociated in aqueous solution.
is a strong electrolyte. Hence it gets completely dissociated in aqueous solution.
is a strong electrolyte. Hence it gets completely dissociated in aqueous solution.
is a strong electrolyte. Hence it gets completely dissociated in aqueous solution.
is a sparingly soluble salt. Hence it is not dissociated and hence dissolved in water. This is due to the fact that both 
and 
ions are similar in size. Hence crystal structure of is quite stable. Hence is reluctant to undergo any dissociation in aqueous solution.
