4.550 g of Na2SO4 are added to 0.350 L of water. To this solution, 0.085 L of water were added. What is the new concentration of the solution?
Answers
Answer:
0.0736 M or 10.4 g/L
Explanation:
First we convert 4.550 g of Na₂SO₄ into moles, using the molar mass of Na₂SO₄:
4.550 g ÷ 142.04 g/mol = 0.0320 molThen we calculate the final volume of the solution:
Final Volume = 0.350 L + 0.085 LFinal Volume = 0.435 LNow we can proceed to calculate the concentration -in molarity- of the solution:
Molarity = moles / liters0.0320 mol / 0.435 L = 0.0736 MIn g/L the concentration would be:
4.550 g / 0.435 L = 10.4 g/LThe form in which the chemical energy is stored in cells during photosynthesis

the pressure of a 250.0 mL volume of gas under 4.0 atm of pressure is decreased to 1.0 atm at constant tempture what is a new volume
Answers
Answer:
1000 mLExplanation:
The new volume can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we're finding the new volume
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
We have
[tex]V_2 = \frac{250 \times 4}{1} = 1000 \\ [/tex]
We have the final answer as
1000 mLHope this helps you
Which statement is correct?
Natural processes happen spontaneously when they decrease the entropy of a system because entropy increase is counteracted by the flow of enthalpy from high temperatures to low temperatures.
Among solids, liquids, and gases, solids generally have the highest entropy because solid particles are the least mobile, and entropy is inversely related to mobility of particles.
Any change that increases the number of particles in a system increases entropy because it increases the randomness and disorder of the system.
Dissolving table salt (NaCl) in water leads to a decrease in entropy because salt particles, which are numerous individual crystals in solid form, become a homogenous solution in water.

Answer:

Explanation:
Imagine dropping a glass pitcher on a hard surface. The pitcher breaks into numerous shards. If the shards were collected and dropped again, they would tend to break into smaller shards; they would not reassemble themselves into a pitcher. In the universe, there is a tendency for order to be replaced with disorder. This tendency is related to a concept called entropy. The formal definition of entropy is a measure of the degree of randomness and disorder in a system.
How many atoms does NH4Br have
Answers
Answer:
6
Explanation:
bromine has 1, hydrogen has 4 and nitrogen has 1 therefore equaling 6
The number of atoms in NH₄Br is six.
What is an atom?An atom is a particle of matter that uniquely defines a chemical element. An atom consists of a central nucleus that is surrounded by one or more negatively charged electrons. The nucleus is positively charged and contains one or more relatively heavy particles known as protons and neutrons.
Atoms are the basic building blocks of matter. Anything that takes up space and anything with mass is made up of atoms.
In the given formula, there is one N atom, four H atoms and one Br atom making a total of six atoms.
Therefore, the number of atoms in NH₄Br is six.

Write two paragraphs about what would happen if your whole body was put in a low pressure environment ?
Answers
Answer:
Reduced air pressure also has a serious effect on the human body. Reduced air pressure means that there is less oxygen available to the body. For lungs to inflate, the air pressure in your lungs has to be less than the air outside the lungs. This is because air moves from high-pressure areas to low-pressure areas.

Explanation:
The relationship between the temperature and the volume of a gas at a constant pressure can be described using Charles' law:
V₁*T₂ = V₂*T₁That means that the temperature and the volume of a gas are directly proportional: The higher the temperature, the higher the pressure. If one of those factors is increased twofold, the other one will be increased twofold as well.

What is the molarity of a solution with 0.5 moles of potassium fluoride dissolved to make 50 mL of solution?
A.0.1 mol/L
B.10 mol/L
C.1.72 mol/L
D.1450 mol/L
Answers
Answer: B
Explanation: molarity = concentration c= n/V = 0.5 mol/ 0.05 l = 10 mol/l
The molarity of a solution is the number of moles of its solute divided by volume in liters. The molarity of the 50 ml solution containing 0.5 moles of potassium fluoride is 10 M or 10 molar.
What is molarity ?Molarity is a common term used to express the concentration of a solution. It is the ratio of number of moles of solute particles to the volume of solution in liters. Hence, its unit is mol/L or molar.
The molarity of a solution is a colligative quantity as well as temperature dependent.
Given,
no.of moles of potassium fluoride salt in water = 0.5 moles.
volume of solution = 50 ml
1 L = 1000 ml
then 50 ml = 0.05 L.
Molarity = no.of moles of solute/ volume of solution in L
M = 0.5 moles/ 0.05 L
= 10 M.
Therefore, the molarity of the given solution is 10 molar.

What is the freezing point, in °C, of a solution made with 1.31 mol of CHCl₃ in 530.0 g of CCl₄?
Answers
Answer:
-96.6°C
Explanation:
Given:
moles CHCl3 = 1.31 molmass CCl4 = 530.0 gmass CCl4 = 530.0 g * (1 kg / 1000)
mass CCl4 = 0.5300 kg
First calculate the molality (m) of the solute, which is the moles of solute divided by the kg of solvent ([tex]\frac{moles}{kg}[/tex]):
molality CHCl3 = (mass moles CHCl3) / (mass CCl4 in kg)
molality CHCl3 = (1.31 mol) / (0.5300 kg)
molality CHCl3 = 2.471698m
Decrease in freezing point of solvent = (Kf) * (molality of solute)
Decrease in freezing point of CCl4 = (Kf) * (molality CHCl3)
Decrease in freezing point of CCl4 = (29.8°C/m) * (2.47m)
Decrease in freezing point of CCl4 = 73.6566°C
Then use the molality of the solute to calculate the change in freezing point and subtract the change from the original freezing point.
Freezing point of solution =
(freezing point of pure solvent) - (Decrease in freezing point)
Freezing point of solution = (-22.9°C) - (73.66°C)
Freezing point of solution = -96.6°C
