Answer:
lower layer
Explanation:
Usually to identify halide ions in solution you use silver nitrate which readly react with Cl⁻, Br⁻ and I⁻ ions to form silver halide salts with different colors depending on the ion present in the solution.
Now, because the silver halide salts are insoluble in water and have a density higher that the water they will stay in the lower part of the test tube.
Answer:
New pressure is 5.40 atm
Explanation:
When T° and moles remain constant, we should use these relation to determine pressure, or also volume
P₁ . V₁ = P₂ . V₂
1.80 atm . 3L = P₂ . 1L
(1.80 atm . 3L ) / 1L = P₂
5.40 atm = P₂
It should be noted that when Brian first sorted out his thoughts, the first thing that he thought would happen next is that he would probably be rescued that day.
It should be noted that in Chapter 5 of Hatchet, Brian wakes up in the forest and then, he realized that he was desperately thirsty.
When Brian first sorted out his thoughts, he figured this was the first day after the crash and that he would probably be rescued that day. He believed that he was going to wither up and die if he doesn't get anything that he'll drink.

Answer:
CaC2 + 2H20 ⇋Ca(OH)2 + C2H2
Explanation:
CaC2 + A H20 ---> Ca(OH)2 + A C2H2
This is calcium carbide reacting with water to produce calcium hydroxide and ethyne commonly called acetylene.
Let's now balance the equation.
CaC2 + 2H20 ⇋Ca(OH)2 + C2H2
Given are:
1) CuSO4 + BaCl2 ---> BaSO4 + CuCl2
2) <span>Pb(NO3)2 + 2NaCl ---> PbCl2 + 2NaNO3
3) </span><span>N2 + 3H2---> 2NH3
4)</span><span>K2SO4 + BaCl2---> BaSO4 + 2KCl
Among the 4 reactions above, the only oxidation - reduction reaction is number 3:
N2 + 3H2 ----> 2NH3
since the oxidation numbers of N and H decreased and increased, respectively making the reaction RedOx. </span>
