Answer:
You just have to take the periodic table of the elements, take the element that interests you. Then, you look at the formula of the element, at the top left you find the number of neutrons and protons and at the bottom left you find the number of protons. Then you just have to make the number from the top left minus the number from the bottom left.
Explanation:
4 covalent bonds can be made in one silica atom
The equilibrium constant could be found using the relationship Kaq = [H^+] [HCOO-]/HCOOH
<h3>What is the equilibrium constant?</h3>
The equilibrium constant is a value that shows us the extent to which reactants are converted into products. We know that a very high value of the equilibrium constant implies that the reactants are mostly converted into products.
Now we have the equation of the reaction as; HCOOH(aq)⇌H^+(aq) + 〖HCOO〗^- (aq). The equilibrium constant ca now be written in terms of Kaq.
Thus the equilibrium constant is;
Kaq = [H^+] [HCOO-]/HCOOH

Answer is: mass fo ammonium chloride is 93.625 grams.
V(NH₄Cl) = 5 L.
c(NH₄Cl) = 0.35 M.
n(NH₄Cl) = V(NH₄Cl) · c(NH₄Cl).
n(NH₄Cl) = 5 L · 0.35 mol/L.
n(NH₄Cl) = 1.75 mol.
M(NH₄Cl) = 14 + 1·4 + 35.5 · g/mol = 53.5 g/mol.
m(NH₄Cl) = n(NH₄Cl) · M(NH₄Cl).
m(NH₄Cl) = 1.75 mol · 53.5 g/mol.
m(NH₄Cl) = 93.625 g.
Answer:
Explanation:
Here, we want to get another name for the theoretical value
The theoretical value is simply the value that has been accepted as true
Thus, we can call the theoretical value the true value
