Answer:
The sun.
Explanation:
It is closer to Earth, therefore bigger to us, and not just a small point of light.
Answer:
Number of neutrons and stability
Explanation:
An isotope of an element is basically the same element but with different number of neutrons. For example here, boron can exist in the forms of boron-10 and boron-11, and so the latter would have one more neutron than the former one.
Adding an extra neutron may or may not disrupt the strong force that much, and so the half-life and stability of the new isotope can be slightly different than its most stable one.
Answer:
138.39 g/mol
Explanation:
Formula mass is a synonym for molar mass, which is the sum of all the masses of the elements. These can be found on a periodic table.
Because this is hydrated, the formula needs to include H2O.
MgSO4 + H2O
Mg + S + 4O + 2H + O
24.31 + 32.07 + (4*16) + (2*1.008) + 16 = about <u>138.39</u>
Answer:
temperature 3000 km below the surface of earth is varied, it's harder to know the actual temperature, it can be found around 3,000 - 3,500 degrees Celsius
It would be Violet because it has the shortest wave length, while red has the longest wave length so it comes out the least of the colors.
