Answer:

Ozone is good in the stratosphere because it absorbs all of the most energetic ultraviolet radiation (UV-C), most of the UV-B radiation and some of the least energetic UV radiation (UV-A). Ozone is “bad” in the troposphere because it is harmful to breathe and is the primary component of smog in summer.

Answer:

3.636 grams of sodium bicarbonate is required.

Explanation:

Using ideal gas equation:

PV = nRT

where,

P = Pressure of gas = 753.5 mmHg = 0.9914 atm

( $1 atm = 760 mmHg$ )

V = Volume of gas = 1.08 L

n = number of moles of gas = ?

R = Gas constant = 0.0821 L.atm/mol.K

T = Temperature of gas = 24.5 °C= 297.65 K

Putting values in above equation, we get:

$(0.9914 atm)\times 1.08 L=n\times (0.0821L.atm/mol.K)\times 297.65K\\\\n=0.0438 mole$

Percentage recovery of carbon dioxide gas = 49.4%

Actual moles of carbon dioxide formed: 49.4% of 0.0438 mole

$\frac{49.4}{100}\times 0.0438 mol=0.02164 mol$

$2NaHCO_3\righarrow Na_2CO_3+H_2O+CO_2$

According to reaction ,1 mol is obtained from 2 moles of sodium bicarbonate.

Then 0.02164 moles f carbon dioxide will be obtained from:

$\frac{2}{1}\times 0.02164 mol=0.04328 mol$

Mass of 0.04328 moles pf sodium bicarbonate:

0.04328 mol × 84 g/mol = 3.636 g

3.636 grams of sodium bicarbonate is required.

Describe the particles of a solid, liquid, and gas. For each, be sure to tell how far apart they are and how fast or slowly they

Art [367]

Answer:

Solid

A solid is a state of matter where the particles are tightly packed together, they are very close together

They vibrate, they move very slowly

Liquid

A liquid has free-flowing particles, but they may not leave the container
They move at medium speed

Gas

A gas moves very freely, they leave the container, and they may not be captured in its entirety
It moves very fast because it is heated

Hope this helps :)

What is the mass in grams of 2.0 moles of NO2

mote1985 [20]

Use your periodic table to get 1 mol. Look up the atomic masses. I'll round the numbers since every periodic table is different.

N = 14
O2 = 2 *16
Total = 30 grams / mol

Therefore 2 mols = twice as much = 60 grams.
