Answer:
Every chemical equation follows to the law of conservation of mass, which states that matter cannot be created or destroyed. When you have an equal number of atoms of an element is present on both sides of a chemical equation, the equation is balanced therefore it is following the law of conservation of mass.
Explanation:
<span>0.72 mL of solution will have 180 mg of amoxicillin.
For this problem, you need to calculate the equivalent ratio of volume as to the ratio of amoxicillin. So
180/500 = X/2.0
Multiply both sides by 2
2 * 180/500 = X
360/500 = X
18/25 = X
0.72 = X
So you need 0.72 mL of solution to get 180 mg of the drug.</span>
Adding carbon to iron to make steel does make it stronger and tougher, up to a point. Then it will get stronger but less tough (ie like cast iron). Carbonstrengthens iron by distorting its crystal latice. This distortion is similar in effect to work hardening.
increases iron’s conductivity.
Answer: 
Explanation:Bond energy of H-H is 436.4 kJ/mole
Bond energy of C-H is 414 kJ/mol
Bond energy of C=C is 620 kJ/mol
Bond energy of C≡C is 835 kJ/mol
= {1B.E(C≡C)+2B.E(C-H) +1B.E(H-H)} - {1B.E(C=C)+4B.E(C-H)}
3s it is what it says sorry if this is wrong but I just did a qu like this and that's what it was
