Crust

Core

Explanation:

For any terrestrial planet, the crust would be the coolest layer and the core would be the hottest layer.

Terrestrial planets or the inner planets made up rocky balls. They have layers that are differentiated.

Typically, they are made up of crust, mantle and the core.

The crust is the outermost layer.

The mantle is the middle layer and core is the inner most layer.

These planets are Mercury, Venus, Earth and Mars.

The outermost layer is usually the coldest part.

The innermost layer is the hottest part which is the core

How is molarity affected if some solution splashes out of the flask during titration?
Annette [7]
<span>If you used more water, the molarity would go down since molarity is moles/liter, and the opposite if you used more water. 

If the acid absorbed water, the molarity would go down because the absorbed moisture will skew the weight of the acid up. 

That would make the molarity go down since there would have been unreacted acid in the spilled liquid.</span>

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Copper has two naturally occurring isotopes, 63Cu (isotopic mass 62.9296 amu) and 65Cu (isotopic mass 64.9278 amu). If copper ha
Semenov [28]

Answer:

Percentage of first isotope = 69.152 %

Percentage of second isotope =  30.848 %

Explanation:

The formula for the calculation of the average atomic mass is:

Average\ atomic\ mass=(\frac {\%\ of\ the\ first\ isotope}{100}\times {Mass\ of\ the\ first\ isotope})+(\frac {\%\ of\ the\ second\ isotope}{100}\times {Mass\ of\ the\ second\ isotope})

Given that:

For first isotope:

Let % = x %

Mass = 62.9296 amu

For second isotope:

% = 100 - x  %  (Since, there are only two isotopes)

Mass = 64.9278 amu

Average mass = 63.546 amu

Thus,  

63.546=\frac {x}{100}\times {62.9296}+\frac {(100-x)}{100}\times {64.9278}

Solving,

1.9982 x = 138.18

Thus,

<u>Percentage of first isotope = x = 69.152 %</u>

<u>Percentage of second isotope = 100 - x % = 30.848 %</u>
