Answer:

Please check attachment

Explanation:

Here in this question question, we are concerned with writing the Lewis structure for the given molecule.

The Lewis structure is simply using dots to represent electrons which are not involved in the bonding.

That is, we shall be using dots to represent the non-bonding pairs of electrons around the atoms which are central.

Answer:

Endothermic

Explanation:

The temperature of the water decreased.

The water lost heat.

The heat must have gone into getting the KNO₃ into solution.

So, the dissolving of KNO₃ in water is endothermic.

You believe you have cracked a secret code that uses elemental symbols to spell words. The code uses numbers to designate the el

Stells [14]

Explanation:

Atomic numbers for neutral atoms are the same as the number of electrons. The number of electrons are used in writing the subshell notation where we can see the highest princpal quantum number(n).

In order to solve this problem, a good knowledge of the periodic table and shell notation is required.

For example;

Given a number 5;

We know the number is made of both the atomic number of the element and the highest quantum number.

It is easier for us to know the highest quantum number from the shell notation:

shell notation 1s²2s²2p¹

highest principal quantum number is 2

We are left with atomic number 5-2, which is 3

The element is therefore Li.

_______ is the amount of heat necessary to raise the temperature of 1 gram of a substance by 1 degree Kelvin. A. A calorie B. En

Maksim231197 [3]

<h2>The required option d) "specific heat" is correct.</h2>

Explanation:

To raise the temperature of any substance or material of certain mass to respective temperature it requires some amount of heat.
Specific heat is the amount of heat necessary to raise the temperature of the substance of 1 gram to 1 Kelvin.
It is the amount of heat which is required to raise the temperature per unit mass to per unit temperature.
Thus, the required "option d) specific heat" is correct.

Identify three additional ways scientists learn about the Earth's interior.

anygoal [31]

The Equator is an imaginary line around the middle of the Earth. It is halfway between the North and South Poles, and divides the Earth into the Northern and Southern Hemispheres. The Equator is the line of 0 degrees latitude. Each parallel measures one degree north or south of the Equator, with 90 degrees north of the Equator and 90 degrees south of the Equator. The latitude of the North Pole is 90 degrees N, and the latitude of the South Pole is 90 degrees S hope this helps
