The answer would be: Igneous Rocks
Answer:
A is correct...B and C wrong I believe
Explanation:
So basically the reason A should be correct is because all enzymes do is provide alternative mechanisms for reaction to proceed and in that alternative mechanism the activation energy is lowered allowing the reactions to progress at greater speeds.
So A makes sense because The aerodynamic shape of a car, like an enzyme, does not supply energy to the car, but it can make it easier for the car to move (basically like an enzyme the car's shape is allowing the car to move faster... enzymes are not consumed in a reaction; they simply help it to occur.)
B is not correct because enzymes do not provide energy for reaction to occur. All they provide is an alternate mechanism where the activation energy is lowered so the reactions can occur at greater rate.
C is not correct because some reactions can occur without enzymes its just that they will occur at a much slower speed.
Hope this helps! I think this should be correct plz double check with your friends.
I think it’s law conservation of mass.
So 200g(NH3)-47g(N2)=153g(H2)
H2+N2—->NH3
There is 6 non - bonding pairs.
Let me show you one easy method to do this.
o22-, oxygen valence electron = 6 here we have two so total 12, and -2 that means we add electrons so it’s all equal to 14 right.
whenever need to find lone pair, subtract the number you get with the lowest multiple of 8.
here we total 14 valence electron right so lowest multiple of 8 would be 8.
so 14 - 8 = 6 and that is our answer.
Let me know if you have Problem with chemistry.
A nucleotide is composed of a phosphate group, sugar, and nitrogen base. DNA is made of 2 strands of nucleotides linked together by covalent bonds between the phosphate and sugar of each nucleotide. The strands of nucleotides are linked together by hydrogen bonds creating DNA. Hope this helps and sorry if I made a mistake.
