The answer to this question would be: 3.125%
Half-life is the time needed for a radioactive molecule to decay half of its mass. In this case, the strontium-89 is already gone past 5 half lives. Then, the percentage of the mass left after 5 half-lives should be:
100%*(1/2^5)= 100%/32=3..125%
Light moves in a straight line except at surfaces between different transparent materials, where its path bends.
Answer:
Sodium is more reactive than sulfur.
Valency of Sodium is 1.
Valency of Sulfur is 2.
(Valency is the number of electrons in the outermost orbit of an atom which can be taken, given out or shared by an atom.)
Answer is: adenosine triphosphate.
ATP is made of three components: the triphosphate (P), the sugar ribose and a nitrogenous base (adenine).
ATP is short for adenosine triphosphate
Adenosine triphosphate converts to either the adenosine diphosphate (ADP) or adenosine monophosphate (AMP), in this process energy is released.
Answer:
C. Decrease the concentration of hydrogen gas
Explanation:
<u><em>Decreasing the concentration of hydrogen gas</em></u><em> would cause the equilibrium to shift to the right.</em>
According to Le Chatelier's principle, when a reaction is in equilibrium and one of the constraints affecting reactions is varied, the equilibrium will shift so as to annul the effects of the change.
Decreasing the concentration of dihydrogen sulfide will cause the equilibrium to shift to the left because as reactants are removed, more of the reactants would be formed.
Increasing the pressure of the system will also cause the equilibrium to shift to the left because the total number of moles of reactants is less than that of products. Hence, more of reactants would be formed with increased pressure.
Increasing the concentration of carbon disulfide will cause the equilibrium to shift to the left because as more of the products are added into the reaction, more of the reactants will begin to form.
<u>The only reason for the equilibrium to shift to the right causing more of the products to be formed is decreasing the concentration of hydrogen gas which happens to be one of the products. As more of the products are removed from the reaction, the equilibrium will shift to ensure that more products are formed.</u>
The correct option is C.
