Answer:
D) The sun is a burning ball of gas, and the moon revolves around a planet.
Explanation:
Unlike what Jack has written in his table, the sun is comprised of 92% gas and has no definable rocky layer or even dust. The moon revolves specifically around the Earth.
Answer:
it does not show the actual number of atoms in that molecule
610grams that is the maxium because if you do 100+500+10 which is 610
Answer:
The coefficient of KClO₃ is 2.
Explanation:
Chemical equation:
KClO₃ → KCl + O₂
Balance chemical equation:
2KClO₃ → 2KCl + 3O₂
The balanced chemical equation must have equal number of atoms in both side of equation.
In given chemical reaction without balancing, there are two oxygen atoms on right side while on the left side three atoms are present. So we multiply it with the coefficient two to balance the atoms of oxygen. The number of potassium atoms and chlorine atoms on left side becomes two by adding coefficient two, that's why we also add two with KCl on right side to balance the equation.
<span>The water alone can perform chemical weathering with the aid of other chemicals which usually form acids that breaks the internal composition of the material. Hot & cold climates usually cause the flaking the outer layers of a rock (thermal expansion) but it belongs to physical weathering.
However, Physical and chemical weathering work together to disintegrate the rock more easier.
I can't specify a climate well because chemical weathering doesn't involve climate too much.
