Answer:
the volume of CHCI3 = 7.87 ml
the volume of CHBr3 = 12.13 ml
Explanation:
From the given information:
We all know that 1 g/cm^3 = 1 g/ml
The density of boron = 2.34 g/ml
The Volume of the liquid mixture = 20 ml
Recall that:
Density = mass/volume
Mass = Density × Volume
Mass = 2.34 g/ml × 20 ml
Mass = 46.8 g
Suppose the volume of CHCI3 be Y and the Volume of CHBr3 be 20 - Y
Then :
Y (1.492) + 20-Y(2.890) = 46.8
1.492Y + 57.8 - 2.890Y = 46.8
- 1.398 Y = -11
Y = -11/ - 1.398
Y = 7.87 ml
Therefore, the volume of CHCI3 7.87 ml
the volume of CHBr3 = 20 - Y
= 20 - 7.87
= 12.13 ml
Answer:
=10 joules
when multiplying with newtons ( the unit of force)
by a perimeter, it will becone joules, but the specific amount depends on how many newtons and metres there are
Answer:
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.

Hopes this helps and plz mark me brainliest!
A chemical change alters the chemical makeup of a substance. So, wood burning would be a chemical change. The others just alter the physical makeup of the substance.
Answer:
Volume will decreased by decreasing the amount of gas.
Explanation:
The amount of gas and volume are directly related to each other. By decreasing the amount of gas volume will decrease by keeping the temperature and pressure constant.
Mathematical expression:
V ∝ n
V = Kn
we put the K by removing the sign of proportionality.
K = proportionality constant
n = amount of gas
V = volume of gas
The volume- amount relation is called Avogadro law.
By increasing the amount of gas volume will also goes to increase.
