NaC2H3O2 is called sodium acetate (CH3COONa)
2CH3COONa(aq) + Pb(NO3)2(aq) -> 2NaNO3(aq) + (CH3COO)2Pb (aq)
The reaction will not occur because no products will be precipitated, like one of the reactants is in solid form
Answer:
There are 255, 85 grams of Strontium in 2,92 moles.
Explanation:
We perform a simple rule of three to calculate the number of grams, knowing that one mole of Sr weights 87, 62 grams:
1 mol Sr---------87, 62 grams
2,92 mol Sr-----x=(2,92 mol Sr x-87, 62 grams)/1 mol Sr= 255,8504 grams
Answer: The specific heat of the unknown metal is 
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q = Heat absorbed=
Joules
m= mass of substance = 86.8 g
c = specific heat capacity = ?
Initial temperature of the water =
Final temperature of the water =
Change in temperature ,
Putting in the values, we get:


The specific heat of the unknown metal is 
Answer:
MgCl2 = 24 + 2(35.5)
= 95
mass of substance = mol × molar mass
= 0.119 × 95
= 11.305 g
