Answer: Option (b) is the correct answer.
Explanation:
The given data is as follows.
M
M
As expression for
will be as follows.
![K_{sp} = [Ca^{2+}][C_{2}O^{2-}_{4}]](https://tex.z-dn.net/?f=K_%7Bsp%7D%20%3D%20%5BCa%5E%7B2%2B%7D%5D%5BC_%7B2%7DO%5E%7B2-%7D_%7B4%7D%5D)
= 
And, expression for ionic product will be as follows.
Q = ![[Ca^{2+}][C_{2}O^{2-}_{4}]](https://tex.z-dn.net/?f=%5BCa%5E%7B2%2B%7D%5D%5BC_%7B2%7DO%5E%7B2-%7D_%7B4%7D%5D)
= 
=
Since, it is shown here that ionic product is less that solubility product. Hence, no precipitate will form.
Thus, we can conclude that nothing will happen since Ksp > Q for all possible precipitants.
Answer:
The most accurate way to determine an object's volume, especially in the case of an irregularly shaped object, is to immerse it in water and measure the amount of water it displaces. A graduated cylinder large enough to hold both the object and enough water to fully immerse it is the best tool for this job.

[RxN - Balanced] CH₄ + 2O₂ → CO₂ + 2H₂O
[Given] 2 mol CH₄
[Solve] x g O₂
<u>Step 2: Identify Conversions</u>
[RxN] 1 mol CH₄ → 2 mol O₂
[PT] Molar Mass of O - 16.00 g/mol
Molar Mass of O₂ - 2(16.00) = 32.00 g/mol
<u>Step 3: Stoichiometry</u>
- Set up conversion:

- Multiply/Divide:

<u>Step 4: Check</u>
<em>Follow sig fig rules and round. We are given 1 sig fig.</em>
128 g O₂ ≈ 100 g O₂
Answer:
2k+2hcl---2kcl+h2
Explanation:
because we have to balance it and in order to balance it we have to make it in equal form
