Answer:

The motion of the water molecules increase as heat is added.

Explanation:

Hello!

In this case, in general terms, one can know that molecules and heat have a relationship by which one affects the other, more specifically, the heat affects how the molecules behave. In such a way, as the heat added to a system increases its internal energy, one can notice that energy speeds up the molecules because they acquire such energy and the motion starts being increased, it means, the molecules start moving or vibrating faster than before of that heat addition. This is due to the increase of the internal energy, which based on the first law of thermodynamics is related with the velocity of the molecules.

Best regards!

A certain substance X has a normal freezing point of −3.1°C and a molal freezing point depression constant =Kf·6.23°C·kgmol−1. C
muminat

Answer:

Freezing T° of solution =  - 7.35 °C

Explanation:

This is about the freezing point depression, a colligative property which depends on solute.

The formula is: Freezing T° pure solvent - Freezing T° solution = m . Kf . i

Freezing T° of pure solvent is -3.1°C

At this case, i = 1. As an organic compound the urea does not ionize.

We determine the molality (mol/kg of solvent)

We convert mass to moles:

12.3 g . 1mol / 60.06 g = 0.205 moles

0.205 mol / 0.3 kg = 0.682 mol/kg

We replace data in the formula:

-3.1°C - Freezing T° of solution  = 0.682 mol/kg . 6.23 kg°C/mol . 1

Freezing T° of solution = 0.682 mol/kg . 6.23 kg°C/mol . 1 + 3.1°C

Freezing T° of solution =  - 7.35 °C

Are two atoms of the same element identical??​
Neko [114]
No. Although two such atoms are essentially chemically identical (they will chemically react in the same way), they are not completely identical.

HELP ASAP!!! WILL GIVE BRAINLIEST! THESE FOUR QUESTIONS PLEASE!
Vesna [10]

1. 12.992 L

2. 2.42 moles

3. 275.52 L

4. 567.844 g

<h3>Further explanation</h3>

Given

moles and volume at STP

Required

mass, volume and moles

Solution

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.

1. 0.58 moles ammonia :

Volume = 0.58 moles x 22.4 L = 12.992 L

2. 77.5 grams of O₂ :

Moles = 77.5 grams x (1 mol/32 grams) = 2.42

3. 12.3 mole of Bromine gas :

Volume = 12.3 mole   x (22.4 L/1 mole) = 275.52 L

4. 4.8 moles iron(II)chloride :

Mass = 4.48 moles x molar mass ( 126,751 g/mol) = 567.844 g
