How can we freeze water in the classroom

guajiro [1.7K]

You have many different ways possible. If you have a freezer in the classroom you could do that. If you made it really cold in the room and stopped all air flow in the room so it stayed cold you would be able to freeze it.

Make sure to thank me

Place the following molecular ions in order from smallest to largest bond order: <img src="https://tex.z-dn.net/?f=C_2%5E%7B2%2B

podryga [215]

Answer:

The correct answer is option 1 "F(2-) "less than" C2(2+) "less than" O(2-) "less than" N(2-)".

Explanation:

Bond order is a term used in chemistry to identify the number of electrons involved in making the bonding between two or more atoms in a molecule. Bond order is equal to half the difference between the number of bonds in the atoms minus the number of antibonds. Therefore, the correct order of bond order from smallest to largest is as follows:

1. F(2-): equals to 0.5 (it has 8 bonds and 7 antibonds)

2. C2(2+): equals to 1 (it has 4 bonds and 2 antibonds)

3. O(2-): equals to 2 (it has 8 bonds and 4 antibonds)

4. N(2-): equals to 2.5 (it has 8 bonds and 3 antibonds)

Aluminum has a specific heat of 897 j/kg c. methanol has a specific heat of 2450 j/kg c.

Vikki [24]

Answer:

$\sf \: correct \: answer \: would \: be \: methanol!$

Explanation:

Specific Heat: The specific Heat of any material is the heat absorbed or evolved by the material to raise or fall it's temperature by 1°C per unit mass of the material.

The heat absorbed or evolved (Q) is directly proportional to the mass of substance(m) and rise or fall of temp(∆T)

The general formula for specific heat is,

$\sf \: \: \: \: \: s = \frac{Q}{m\Delta T}$

Where

s is specific heat,
Q is the Heat absorbed or evolved
m is mass of substance
& ∆T is change is temperature

Now coming to your question,

The specific heat of Aluminium is 897 J/kg °C

The specific heat of Aluminium is 897 J/kg °C& specific heat of methanol is 2450 J/kg ° C

The definition states that, if the specific heat would be more, more amount of heat will be required for per unit change in temperature.

The specific heat of Aluminium is 897 J/kg °C which means for one kilogram aluminium, 897 Joule energy is required to change it's temperature by 1°C & Similarly for one kilogram methanol 2450 joule energy is required.

Hence, the correct answer would be methanol!

Provide a general comparison of the empty space in a solid with that in a liquid as well as

bogdanovich [222]

Assuming that the space within the solid or liquid is vacuum, it is not matter because there is no mass inside. However, there is a volume. The volume inside a solid would have regular straight sides because atoms of a solid is compactly arranged. For liquids, the space could be irregular curves and paths because the atoms in a liquid are free-flowing.
