Determine the formula unit for the compound formed when each pairs of ions interact.

maksim [4K]

The formula unit of compounds formed depends on the valency of the combining ions.

The formula unit is the smallest unit of an ionic substance that gives us a picture of the ratio in which ions are combined in the ionic compound.

Usually, the formula unit is written based on the valency of the ions.

For the ions listed;

Li+ and 02- forms Li2O

Mg2+ and S2- forms MgS

A13+ and CI- forms AlCl3

Na+ and N3- forms Na3N

alisha [4.7K]

The scientific instruments used to heat water to 85 degree Celsius has been graduated cylinder, beaker, thermometer, and hot plate. Thus, option B is correct.

Scientific equipments have been defined as the instruments and glassware that has been used in the scientific study and experimentation.

<h3>Equipments for heating the water</h3>

The water has been heated to the temperature of 85 degrees Celsius. The temperature has to be monitored thus, a thermometer has been used.

The water has been measured to be 1 L, thus the graduated cylinder, and beaker has been used for the measurement and heating of water.

The heat has been provided to the beaker by placing it on a hot plate.

Thus, the scientific instruments used to heat water to 85 degree Celsius has been graduated cylinder, beaker, thermometer, and hot plate. Thus, option B is correct.

If acid precipitation rain changes the ph of a pond from 7.0 to 5.0, the level of hydrogen ion has changed by a factor of ______

Karolina [17]

When pH=7, [H⁺] =10⁻⁷.
When pH=5, [H⁺]=10⁻⁵.

10⁻⁵/10⁻⁷ =10²=100
The level of hydrogen ions increased by factor 100.

A sample of gas has a pressure of 742 torr. What is the pressure in atmospheres?

ycow [4]

Answer:742 torr= approximately 0.976 atm

Explanation:

Since we know that one atm= 760 torr, we can compute the following calculation:

(742 torr/1)*(1atm/760torr)=0.976316 atm

Remember sig figs (3) to round it to 0.976 atm

$\frac{742 torr}{1}$ * $\frac{1 atm}{760 torr}$ =0.976316=0.976 atm

(torr cancels out and we're left with atm)

Hope this helps :)
