Explanation:
1 literThe total of water is equal to 1000.0 g of water
we need to find the molality of a solution containing 10.0 g of dissolved in Na₂S0₄1000.0 g of water
1. For that find the molar mass
Na: 2 x 22.99= 45.98
S: 32.07
O: 4 x 16= 64
The total molar mass is 142.05
We have to find the number of moles, y
To find the number of moles divide 10.0g by 142.05 g/mol.
So the number of moles is 0.0704 moles.
For the molarity, you need the number of moles divided by the volume. So, 0.0704 mol/1 L.
The molarity would end up being 0.0704 M
The molality of a solution containing 10.0 g of Na2SO4 dissolved in 1000.0 g of water is 0.0704 Mliter
Well, there is kinetic energy when the object is in motion. But it will stop eventually because that energy is converted into thermal energy, or heat.
The volume of the marble is 2.3 cube units.
From the question given above, the following data were obtained:
The volume of the marble can be obtained as follow:
V = L × W × H
V = 1.32 × 1.32 × 1.32
V = 2.3 cube units
Thus, the volume of the marble is 2.3 cube units.

Answer:
C boron, germanium, arsenic, silicon
I believe your answer should be C because the heat would move from the soup to the spoon.
