In my point of view, the simple thing to do here is just to exchange the 3+ and the 2- and you will get:
Al2(CO3)3
The logic behind this is that when you have 2 Al^3+, it makes an overall charge of 6+. Additionally, when you have 3 CO^2-, it also makes an overall charge of 6- (because 3 X 2 = 6). Therefore, 6+ and 6- "cancelled" out, and you will have a neutral charge compound.
I hope you understand
Answer:
0.051
Explanation:
Let's consider the following reaction.
2 SO₂(g) + O₂(g) ⇄ 2 SO₃(g)
We can compute the pressures using an ICE chart.
2 SO₂(g) + O₂(g) ⇄ 2 SO₃(g)
I 3.3 0.79 0
C -2x -x +2x
E 3.3-2x 0.79-x 2x
The partial pressure of sulfur trioxide gas is 0.47 atm. Then,
2x = 0.47
x = 0.24
The pressures at equilibrium are:
pSO₂ = 3.3-2x = 3.3-2(0.24) = 2.82 atm
pO₂ = 0.79-x = 0.79-0.24 = 0.55 atm
pSO₃ = 0.47 atm
The pressure equilibrium constant (Kp) is:
Kp = pSO₃² / pSO₂² × pO₂
Kp = 0.47² / 2.82² × 0.55
Kp = 0.051
Answer:
<h3>Step 1: </h3>
To relate the volume and molarity of a solution at two different concentrations, the expression used is :
M₁V₁ = M₂V₂
<h3>
step 2:</h3>
(2M) V₁ = (0.15M)(250ML)
V₁ = 18.75
step 3:

Answer:
10.5!!!!!!!!!!!!!!!!!!!!!!
Because food is made of proteins carbs lipids let s look at proteins polymers of aminoacids aminoacids are bound by covalent bonds they share electrons to for, those proteins so in order to understand food we have to understand the compounds at all levels .
