Answer:
A large quantity
Explanation:
A large quantity will take much longer to melt compared to a small quantity of the same matter.
The rate of melt of a substance is particularly a function of the nature of the substance and the amount of energy supplied to it.
If we assume that we are dealing with different quantities of the same substance, then the one that has more mass will melt faster because less energy would be required to change its state.
A large quantity of matter will take more time to melt.
Answer:
Cm = Cn/n = 0.1/2 = 0.05 (M)
n = 0.05*2= 0.1 mol
m H2SO4= 0.1*98= 9.8 g
m dd H2SO4= 9.8/ 0.98 =10 g
V= 10/ 1.84 = 5.435 ml
Explanation:
Answer:
7p
Explanation:
principal quantum number is 7
n=7( principle shell)
angular momentum quantum number gives sub shell
l = 1 means it is p orbital
so answer is 7p orbital
