Answer: During an El Nino year, weakening winds along the equator lead to warming water surface temperatures that lead to further weakening of the winds
Answer : The specific heat (J/g-K) of this substance is, 0.780 J/g.K
Explanation :
Molar heat capacity : It is defined as the amount of heat absorbed by one mole of a substance to raise its temperature by one degree Celsius.
1 mole of substance releases heat = 92.1 J/K
As we are given, molar mass of unknown substance is, 118 g/mol that means, the mass of 1 mole of substance is, 118 g.
As, 118 g of substance releases heat = 92.1 J/K
So, 1 g of substance releases heat = 
Thus, the specific heat (J/g-K) of this substance is, 0.780 J/g.K
Answer:
4.25% is the final concentration of phosphoric acid.
Explanation:
Initial concentration of phosphoric acid = 
Initial volume of phosphoric acid = 
Final concentration of phosphoric acid = 
Final volume of phosphoric acid = 
( 1L = 1000 mL)



4.25% is the final concentration of phosphoric acid.
A simple solution is basically two substances<span> that are evenly mixed together. One of them is called the solute and the other is the solvent. A solute is the substance to be dissolved (sugar). The solvent is the one doing the dissolving (water).</span>
Answer:
B) Ethanol must act as a competitive inhibitor for the alcohol dehydrogenase and therefore slows the formation of formaldehyde.
Explanation:
An<em> inhibitor</em> is a substance that binds to an enzime and prevents it to react with a substrate. In this case, the inhibitor is ethanol, binding to the enzime (alcohol dehydrogenase) <u>and preventing it to react with methanol and thus from it form the toxic formaldehyde</u>.
A competitive inhibitor has a similar structure to the substrate, that is why it binds to the same active site. In this case, ethanol has a similar structure to methanol, which is why the answer is B and not A.
