Answer:
v = 37.9 ml
Explanation:
Given data:
Mass of compound = 1.56 kg
Density = 41.2 g/ml
Volume of compound = ?
Solution:
First of all we will convert the mass into g.
1.56 ×1000 = 1560 g
Formula:
D=m/v
D= density
m=mass
V=volume
v = m/d
v = 1560 g / 41.2 g/ml
v = 37.9 ml
Answer:
Br
Explanation:
because bromine is more reactive as reactivity increases on moving from left to right in p-block. hope this make sense :)
Answer: 131 g of bromine is required.
Explanation:
The balanced equation will be :

To calculate the moles, we use the equation:
moles of
According to stoichiometry :
2 moles of
require = 3 moles of
Thus 0.544 moles of
require=
of
Mass of
Thus 131 g of bromine is required.
Ni = Nickel
SO4 = Sulphate
2 and 3 in the sub-script are the charges.
So , its name is NICKEL SULPHATE
