Answer:
This is false.
Explanation:
Stars are made of very hot gas. This gas is mostly hydrogen and helium, which are the two lightest elements. ... Most stars have small amounts of heavier elements like carbon, nitrogen, oxygen and iron, which were created by stars that existed before them.
The heat inside the Tupperware causes an increase in pressure and when enough pressure builds, the atoms need somewhere to go and the seal at the top is easiest to break, so the top blows off.<span />
At first, the population of predators would spike and increase quickly, but then over time, gradually decrease.
(This is because at first there's more food, so the predators population increases. But overtime it begins to level out and the predators' population catches up with the prey, and in result, doesn't continue increasing.)
Answer to this question is b
<span>The balanced equation for ammonia (NH3) is 3H2 + N2 ď 2NH3. This equation starts from H2 + N2 ď NH3. We have 1 N and 3 H on the right side (the product side) of the equation, so we multiply each by 2 to get 2 N and 6 H. We do this so that we don’t have an odd number of H atoms. We then balance the left side (the reactant side) of the equation with the right side, N is already balanced, but we have to multiply H by 3 to get 6 H atoms (to match the right side of the equation.</span>
