Answer:
Sediment build up or the movement of water can transfer fossils to different places other than its original place.
<span>Blood.
Luminol is a chemical that comes in a spray. When it is mixed with another chemical called an oxidizing agent it produces a compound that gives off a blue glow temporarily.
Blood contains an oxidizing agent, so if luminol is sprayed on blood it glows blue for about 30 seconds.</span>
At the point when a response achieves a condition of concoction balance under a specific arrangement of conditions, no further changes in the groupings of reactants and items happen. On the off chance that a change is made in the conditions under which the framework is at harmony, substance change will happen so as to build up another balance. The components that can impact harmony are an adjustment in focus, change in weight (or volume), and change in temperature.
I think it might be C because we don't have too much room to dispose of these things with no harm to people
<u>Answer:</u> The volume of hydrogen gas required for the given amount of ethylene gas is 113 L
<u>Explanation:</u>
At STP:
1 mole of a gas occupies 22.4 L of volume
We are given:
Volume of ethylene = 113 L
For the given chemical equation:
By Stoichiometry of the reaction:
of ethylene reacts with of hydrogen gas
So, 113 L of ethylene gas will react with = 
of hydrogen gas
Hence, the volume of hydrogen gas required for the given amount of ethylene gas is 113 L
