a student wants to remove the salt from a mixture of sand and salt in order to get only person he adds water to the mixture why it's the step help

Answers

You would add water to the mixture to dissolve the salt. When the salt is dissolved, you have your sand alone.
Water dissolves the salt and pour out the water let it evaporate and you have separate salt and water

The dry solute has a mass of 0.086 g. 0.113 g of water evaporated while heating. What is the concentration in G solute / mL solvent at 30.1 C? Remember: 1 g = 1 ml for waterA. 0.88
B. 0.0860
C. 0.113
D. 0.761

Answers

The dry solute has a mass of 0.086 g. 0.113 g of water evaporated while heating, the concentration in G solute / mL solvent at 30.1 C is 0.88.

To find the concentration in g solute / mL solvent, we first need to find the mass of the solvent left after evaporation:

Mass of water before evaporation = 0.113 g

Mass of water after evaporation = 0.113 g - 0.086 g = 0.027 g

Since 1 g of water has a volume of 1 mL, the volume of water after evaporation is also 0.027 mL.

Next, we need to convert the temperature to Kelvin:

T = 30.1 + 273.15 = 303.25 K

We can now use the formula:

concentration = (mass of solute / mass of solvent) / (1 - (mass of water evaporated / mass of solvent))

Plugging in the values we get:

concentration = (0.086 g / (0.027 g)) / (1 - (0.113 g / (0.086 g + 0.027 g)))

concentration = 0.88 g/mL

Therefore, the answer is A. 0.88.

Topic 1 Homework Homework – Due in 13 hours T2HW Question 16 - Challenge Homework – Unanswered The distance from San Francisco to Los Angeles is approximately 385 miles. You and your friends decide to cycle from San Francisco to Los Angeles. If the distance between the cities is about 385 miles and your doctor tells you that you need to drink 1 L of water for every 1 km that you cycle, how many Lof water will each cyclist need to drink on the journey? Enter your answer as a number using 3 significant figures without units. Do not enter the word "liters" as part of your answer. 1609 m = 1.0 mi Numeric Answer Unanswered

Answers

Answer:

Each cyclist will need to drink 619 l

Explanation:

Hi there!!

First, let´s convert the miles to kilometers:

If 1.0 mi = 1609 m, then 385 mi will be:

385 mi · (1609 m/ 1.0 mi) ·  (1 km/ 1000 m) = 619 km

Now, if each cyclist need to drink one liter water per kilometer ( I think that´s a lot of water!), for the entire journey each cyclist will need to drink:

619 km · 1 l/km = 619 l

Then, each cyclist will need to drink 619 l.

When an electron moves up to higher energy levels, the atom Choose... a photon of light whereas the atom Choose... a photon of light when an electron drops to a lower energy level. The photons emitted from an atom appear as

Answers

Answer:

Explanation:

When an electron moves from a lower energy level to a higher energy level, energy is absorbed by the atom. When an electron moves from a higher to a lower energy level, energy is released and photon is emitted.

this emitted photon is depicted as a small wave-packet being expelled by the atom in a well-defined direction.
