Answer:

About 30-35%

Explanation:

Glaciers are defined as the large moving blocks of ice that are formed by the gathering and solidification of snow on the high elevated mountains. The poles and near-polar region are suitable locations for the formation of glaciers as the high latitude areas experience a very cold type of climate.

During the last glaciation or ice age, the maximum portion of the earth that was occupied with glaciers was about 30-35% of the total landmass.  

At present, glaciers cover only 10% of the earth's total landmass that includes the glaciers, large ice caps, and the extensive sheets of ice that are present in Antarctica as well as Greenland.

The solubility of lead(ii) chloride is 0.45 g/100 ml of solution. what is the ksp of pbcl2? 4.9 × 10-2 1.7 × 10-5 8.5 × 10-6 4.2
Artyom0805 [142]
Answer:
1.7 * 10^-5

Explanation:
1- get the number of moles of PbCl2:
number of moles = mass / molar mass
number of moles = 0.45 / 278.1 = 1.618 * 10^-3 moles

2- get the concentration of Pb2+:
molarity = number of moles of solute / volume of solution in liters
molarity = (1.618 * 10^-3) / (0.1) = 0.0162 M

3- getting concentration of Cl-:
<span>PbCl2(s) <==> Pb2+(aq) + 2Cl-(aq) 
</span>We can note that:
For a certain amount of Pb2+ formed, twice this amount of Cl- is formed.
This means that:
for 0.0162 M of Pb2+, 2*0.0168 = 0.0324 M of Cl- is formed

4- getting Ksp:
Ksp = [Pb2+][Cl-]²
Ksp = (0.0162)*(0.0324)²
Ksp = 1.7 * 10^-5

Hope this helps :)

If a neutral atom has 24 electrons and 26 neutrons how many protons does it have?​
Salsk061 [2.6K]

Answer:

24

Explanation:

The number of protons in the atom of the neutral element will also be 24.

Protons are the positively charged particles in an atom.

Electrons are the negatively charged particles

Neutrons do not carry any charges at all

Now, in a neutral atom, the charge is balanced and the number of protons and electrons are the same in the atom.

So, since we have been given that the atom has 24 electrons, the number of protons will be 24.
