Answer:
A. the ration is 2 to 3, 2Al + 3H2SO4 has the same balance as 18Al + 3H2SO4
2/3 = 18/27
B. Doesn't need an explanation other than the work you did to balance it.
The structure of tofacitinib with explicit carbon and hydrogen is the first attached picture.
The number of carbon atoms in tofacitinib are 16.
The molecular formula of tofacitinib is .
The structure of tofacitinib with all the filled hydrogen atoms is the second attached picture.
Four Consecutive terms are written as a-3, a-1, a+1,a+3. So
Sum of Terms : 4a=28
a=7
So the terms are 4,6,8,10
Verification : 4^2+6^2+8^2+10^2
= 216
The number of neutrons=Atomic mass-atomic number
no of neutrons=20-10
no of neutrons=10
<h3>
Answer:</h3>
The products of the reaction are; AgCl and NaNO₃
<h3>
Explanation:</h3>
In this question we need to know what is a double displacement reaction;
- A double displacement is a type of replacement reaction in which salts or ionic compounds exchange cations and anions to form new compounds as the products.
- In this case, the complete double replacement reaction is;
AgNO₃(aq) + NaCl(aq) → AgCl(s) + NaNO₃(aq)
- The reaction is also a precipitation reaction as it forms a precipitate as one of the products that is silver chloride (AgCl).
- Therefore, the products of the reaction are; AgCl and NaNO₃
