An N∨2 Molecule shares 3 pairs of electrons and forms a triple bond. Each N atom contributes 3 electrons making three pairs of electrons.
Answer:
a) 
b) 
Explanation:
Hello!
In this case, for this acid-base reaction which also known as a neutralization because sulfuric acid is neutralized with sodium hydroxide, we can write the undergoing chemical reaction as shown below:
However, it needs to be balanced as two sodium atoms are yielded:
Next, since there is a 1:2 mole ratio between the acid and the base, at the equivalence point, at which the moles of acid and base are consumed, we write:
Which can also be written in terms of the given volumes and concentration of the base:
In such a way, we solve for the concentration of sulfuric acid as shown below:
Best regards!
Answer: maybe mixing with an acid? They are all very similar
Explanation:
Maybe because the different acids have different atoms and molecules
Like terms in algebra are terms that have the same variables and power. Constants contain only numbers, we call them constants because their values don't change. Coefficients are the numbers in front of the variable ex: 5y in that expression 5 is the coefficient. So in the expression 2+3a+9a there is one constant which is 2 the likes terms are 3a and 9a because they have the same variable. And the coefficients are 3 and 9 because they are in front of the variable.
Answer: Penicillin G (also called benzylpenicillin) was discovered by accident in 1928. Alexander Fleming, a Scottish physician-scientist was growing a type of bacteria called Staphylococcus Aureus on an uncovered petri dish when it became contaminated with mold spores.
