All alkalis are bases but not all bases are alkalis. True or False?
Answers
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

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
Answers
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.

Why do scientists create proxies?
Answers
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."

a volume of 200.0 mL. What is the density of Rion?
Answers
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]
