Answer: It will decrease.
Explanation:
If you had an equal birth and death rate, the population would theoretically stay the same, but since you have more deaths and less births, the population will decrease.
A student tested a 0.1 M aqueous solution and made the
following observations conducts electricity, turns blue litmus to red and reacts
with Zn(s) to produce gas bubbles. The compound that could be the solute in
this solution is HBr. The answer is number 3.
Answer: 7
Explanation:
50 ml 0.125 M KOH = (50 * 0.125) = 6.25 ml 1 M KOH
similarly 50 ml 0.125 M HCl = 6.25 ml 1 M HCl
so KOH will fully neutralize the HCl so the pH of the medium will be 7
H+ + OH- = H2O
so Kw = [H=][OH-]
= [H+]^2 = 10-14
SO [H+] = 10-7
pH = -log [H+]
pH = -log[10-7]
pH = 7
Answer:
Therefore, the value of K_{p} is 2 \times 10^{9} and value of \Delta G^{o} is -53.2 kJ/mol.
Explanation:
The given question is incomplete. The complete question is :
What is the coefficient of 
when the following equation is properly balanced with the smallest set of whole numbers? 
Answer: The coefficient of is 3
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The balanced chemical reaction is:
The coefficient of is 3
