Answer:
No it is not a physics because in this there is about classification of element so it is in chemistry that's why it is not physics.
Answer:
8.58 g/cm3
Explanation:
density = mass / volume
be attention that the question gives u the length of
one side of the cube so u should calculate the volume
of the cube using your information of math .
1st we calculate the volume of the cube :
V of cube = a 3= axaxa
= 0.250 x0.250 x0.250
= 0.0156 cm3
2nd step
density = mass/volume
= 0.134/ 0.0156 = 8.58 g/cm3
The solution that will have the lowest freezing point is 5.0 SODIUM CHLORIDE.
Adding solute to solvents usually result in the depression of the freezing point. The higher the quantity of the solute that is added, the lower the freezing point of the solution.
Answer:
5.Hey Order of reaction is :-
Y>Z>X
6.Phosphorus is soft, waxy and reactive. It reacts with moist air and gives out light. It ignites spontaneously at about 350C and that's why it is stored under kerosene to prevent its reaction in the atmosphere.
it can be also stored in sealed bottles..
