Chemistry
1 answer:
Delvig [45]3 years ago
7 0

Answer:

Carbon moves from the atmosphere to the land, ocean, and life through biological, chemical, geological and physical processes in a cycle called the carbon cycle. Because some carbon gases are greenhouse gases, changes in the carbon cycle that put more carbon in the atmosphere also warm Earth’s climate.

Magnesium oxide is an ionic compound with a very high melting point and which requires a large amount of energy for melting.

<h3>What are ionic compounds?</h3>

Ionic compounds are compounds which are formed between oppositely charged ions which are held together by electrostatic forces of attraction between the oppositely charged ions.

Ionic compounds are formed when metal atoms donate electrons to non-metals atoms to form ions.

Magnesium oxide is an ionic compound.

The nature of bonding is ionic bonding.

It has a crystalline lattice structure.

The forces of attraction is electrostatic forces of attraction.

It has a high melting point of 2,852 °C, and thus requires a large amount of energy go melting to occur.

Therefore, magnesium oxide is an ionic compound which requires a large amount of energy for melting.

The solubility of co in water at 0c and 1 atm co pressure is 0. 0354 mg of co in 1 ml of water. Calculate the moalrity of aqueso
Dmitriy789 [7]

From all the calculations that were carried out, the concentration of 2atm is 0.0026 M.

<h3>What is molarity?</h3>

The term molarity is defined as the number of moles divided by the volume of the solution. Using the formula; C = kp where

  • C = concentration
  • k = constant
  • p = pressure

C =  0. 0354 * 10^-3 g/28 g/mol × 1000/1 L

C = 0.0013 M

k = C/p = 0.0013 M/1 atm

k = 0.0013 Matm-1

Now;

C =  0.0013 Matm-1 *  2 atm

C= 0.0026 M

How many grams of Lead(II) nitrate are present in 150.0 mL of an Lead(II) nitrate solution that is 0.07268 M?
Lana71 [14]
Hey...
Use the molarity formula
M=moles/L and then convert to grams

0.07268*0.15=moles
<span>0.010902 mol
</span>Pb(NO3)2
1 mole=331.22g
0.010902 moles=

3.61 g
