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

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?

Answers

Answer:

9.46 g/mL

Explanation:

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/mL

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.

Question - If a student is 175 cm tall, how tall is the student in meters?

Answers

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.
