True or false when heat is added to atoms the molecules vibrate much more slowly
Answer:
false
Explanation:
The particles are held together too strongly to allow movement from place to place but the particles do vibrate about their position in the structure. With an increase in temperature, the particles gain kinetic energy and vibrate faster and more strongly

The thermochemical equation for the formation of ammonia (NH3) is shown below. How much energy (kcal) is released when 6.0
mol of H2 reacts?
(Note - when the direction of energy flow is indicated, e.g. "released", the negative sign is not used in the answer.
3 H2(g) + N2(g) →2 NH3(g) triangleH = - 11 kcal
In the formation of NH₃, -22 kcal are released when 6.0 moles of H₂ react.
Let's consider the thermochemical equation for the formation of ammonia.
3 H₂(g) + N₂(g) → 2 NH₃(g) ΔH = - 11 kcal
As we can see, 11 kcal are released when 3 moles of H₂ react. The heat released when 6.0 moles of H₂ react is:
[tex]6.0molH_2 \times \frac{(-11kcal)}{3molH_2} = -22kcal[/tex]
In the formation of NH₃, -22 kcal are released when 6.0 moles of H₂ react.

Explanation:
All alkalis are bases but not all bases are alkalis. True or False?
Answer:
A substance that neutralizes an acid is generally called a base and the basic substances that are soluble in water and alkali and the properties of alkalis are due to these hydroxide ions(OH−). ... - Thus, conclusively it can be said that all alkalis are bases but all bases are not alkali.
Answer:
This is false
Explanation:
it is actually the opposite, all bases don't dissolve in water, but alkali is a base that does dissolve in water. So, alkalis are bases, but not all bases are alkalis

You have been handed a 1892.6g sample of Rion and determine that it has
a volume of 200.0 mL. What is the density of Rion?
Answer:
9.46 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 1892.6 g
volume = 200 mL
We have
[tex]density = \frac{1892.6}{200} \\ = 9.463[/tex]
We have the final answer as
9.46 g/mLHope this helps you

Why do scientists create proxies?
Answer:
Proxies enable scientists to recreate climate conditions in different parts of history.
Explanation:
Proxies are characteristics of the weather in a certain period of time that have been preserved for different weather measurements like temperature, humidity, wind direction, and amounts of precipitation. The reason scientists create proxies because it "enables them to recreate climate conditions from different parts of time to have a better understanding on what weather was like during that time period."

Use metric and U.S. conversion factors to solve the problem.
Question - If a student is 175 cm tall, how tall is the student in meters?
Explanation:
100cm = 1m
1cm=1/100 m
175cm = 175/100 m = 1.75m.
hope this helps you.
If a student is 175 cm tall, then according to the metric system the same student is 1.75 m tall.
What is a Metric system?A metric system may be defined as a type of system that significantly weighs and measures the mass and distance respectively in which the meter is the unit of length and the kilogram is the unit of weight.
A metric system is a standard system of measurement which utilizes the meter, liter, and gram as base units of length for distance, capacity for volume, weight for mass, etc.
According to the question, the height of a student in cm = 175 cm.
Then, from the general conversion rule,
1 meter = 100 cm.
1 cm = 1/100 meter.
175 cm. = 175/100 = 1.75 meters.
Therefore, if a student is 175 cm tall, then according to the metric system the same student is 1.75 m tall.
