Chemistry
1 answer:
lukranit [14]2 years ago
4 0

Answer:

It cant

Explanation:

It can not tell because the size of a human and an object to 2 different sizes. Therefor since they are 2 different sizes they can handle different amounts of temperature.

. The dissolving process is exothermic when the energy
Serhud [2]

Answer:

A

Explanation:

The dissolving process depends on the interaction between solute and solvent (solvation) and the breaking up of the intermolecular bond between solutes. The former is exothermic in nature, while the later is endothermic. Energy is released when solute-solvent particles interact. When this energy exceeds the energy required to break intermolecular bonds between the solute particles, dissolution is exothermic.

cylinder contains 250 g of Helium at 200 K. The external pressure is constant at 1 atm. The temperature of the surroundings is l
brilliants [131]

Answer:

The system gains 126100 J

Explanation:

The heat can be calculated by the equation:

Q = nxCxΔT, where Q is the heat, C is the heat capacity,n is the number of moles and ΔT is the variation of temperature (final - initial). The number of moles is the mass divided by the molar mass, so:

n = 250/4 = 62.5 mol.

The system must be in thermal equilibrium with the surroundings, so if the temperature of the surroundings decreased 97 K, the temperature of the system increased by 97 K, so ΔT = 97 K

Q = 62.5x20.8x97

Q = 126100 J

How many atoms are in 73.9g of potassium oxide
denis-greek [22]

Answer: 4.69(10)^{23} atoms

Explanation:

Firstly, we have to find the Molecular mass of potassium oxide (K_{2}0):

K atomic mass: 39 u

O atomic mass: 16 u

K_{2}O molecular mass: 39(2) g/mol+16g/mol=94 g/mol

This means that in 1 mole of K_{2}O there are 94 g and we need to find how many moles there are in 73.9 g K_{2}O:

1 mole of K_{2}O-----94 g of K_{2}O

X-----73.9 g of K_{2}O

X=\frac{(73.9 g)(1 mole)}{94 g}

X=0.78 mole This is the quantity of moles in 73.9 g of potassium oxide

Now we can calculate the number of atoms in 73.9 g of potassium oxide by the following relation:

N_{atoms}=(X)(N_{A})

Where:

N_{atoms} is the number of atoms in 73.9g of potassium oxide

N_{A}=6.0221(10)^{23}/mol is the Avogadro's number, which is determined by the number of particles (or atoms) in a mole.

Then:

N_{atoms}=(0.78 mole)(6.0221(10)^{23}/mol)

N_{atoms}=4.69(10)^{23} atoms This is the quantity of atoms in 73.9g of potassium oxide

Is salt water a mixture or a solution?
Westkost [7]
Salt water is a solution.
A solution is defined as a mixture where one of the substances dissolves in the other (salt dissolves in water)
You can check this by Googling"difference between mixture and solution", where the first thing that comes up are the words that "an example of a solution is salt water".
