1 answer:

3 0

1. Which of the following is not true of a covalent compound?
It is made of only nonmetals.

2. What type of compound is almost always found as a solid?

Ionic compound is almost always found as a solid because they have very tightly bound structures.

3. Which of the following is not a characteristic of an ionic compound?

It is formed when atoms share electrons.

4. Covalent compounds are formed when
a nonmetal bonds with a nonmetal.

5. What is the relationship between a compound and the elements it is made from?

The compound may have properties that are very different from those of the elements.

what can we tell about an unknown substance based on its properties. Its science btw, i couldnt find the science subject

dsp73

Answer:

Measuring its density and comparing your result to a list of known densities, or other properties that give you useful info

Explanation:

You can use observations about substances to form a hypothesis about the substance by comparing it to others. Ex: if something is magnetic it must be made of one or more of the elements iron, cobalt, or nickel.

How do I draw energy level diagrams?

finlep [7]

Energy levels inside an atom are the specific energies that electrons can have when energy occupies specific orbitals. Electrons can be excited to higher energy levels by absorbing energy from the surroundings, an equivalent light is emitted when an electron returns from a high energy state to a lower one. Representation of this diagrammatic is known as the energy level diagram.

The heat required to change 1 gram of a solid at its normal melting point to a liquid at the same temperature is called the heat

Darya [45]

Answer:

Heat of fusion

Explanation:

The heat required to change 1 gram of a solid at its normal melting point to a liquid at the same temperature is called the heat of fusion.

The formula for the heat of fusion is given by :

$\Delta H=n\Delta H_{fus}$

Where

n is no of moles

$\Delta H_{fus}$ is molar heat of the substance

Hence, the correct answer is heat of fusion

Which of these electron transitions correspond to absorption of energy and which to emission?

Keith_Richards [23]

The electron transitions representing absorption of energy are:

(a) n = 2 to n = 4

(d) n = 3 to n = 4

and those which represents emissions of energy are:

(b) n = 3 to n = 1

An electron emits energy when it jumps from a higher energy level to a lower energy level transitions.

An electron absorbs energy to jump from a lower energy level to a higher energy level transitions.

(a) n = 2 to n = 4

Here, the initial level (2) is lower than the final level (4).

Hence energy is absorbed.

(b) n = 3 to n = 1

Here, the initial level (3) is higher than the final level (1).

Hence energy is released.

Here, the initial level (5) is higher than the final level (2).

Hence energy is released.

(d) n = 3 to n = 4

Here, the initial level (3) is lower than the final level (4).

Hence energy is absorbed.

The question is incomplete. Find the complete question here:

Which of these electron transitions correspond to absorption of energy and which to emission?

(a) n = 2 to n = 4

(b) n = 3 to n = 1

(d) n = 3 to n = 4
