Ka for weak acids is ---> Ka= (X)²/ (initial- X)
initial= 0.0400 M
to find X, you can find the H concentration using pH
[H+]= 10^-pH
[H+]= 10^-1.80= 0.016 which is X
ka = (0.016)²/ (0.0400 - 0.016) = 0.011
Based on their percent concentration, the 5% sugar solution contains more water.
<h3>What is the concertation of a solution?</h3>
The concentration of a solution is the amount of solute dissolved or present in a given volume of solution.
Concentration of solutions can be expressed as either:
- molar concentration
- mass concentration
- percentage concentration
The concentration of the sugar solutions are given as percent concentration.
The 5% sugar solution contains 5% sugar and 95% water
The 10% sugar solution contains 10% sugar and 90% water.
Therefore, the 5% sugar solution contains more water.

Answer: 2LiBr(aq) + F2(g) —> 2LiF + Br2
explanation: Br and F are both nonmetals. Nonmetals should only replace other nonmetals in a single replacement reaction.
interstellar cloud of dust, hydrogen, helium and other ionized gases.
Answer:
Anaphase
Explanation:
Two separate classes of movements occur during anaphase. During the first part of anaphase, the kinetochore microtubules shorten, and the chromosomes move toward the spindle poles. During the second part of anaphase, the spindle poles separate as the non-kinetochore microtubules move past each other.
