The answer should be C
The reason for this is because:
There are 2 "I" on the right side of the equation but only 1 on the left. This means you need to add a 2 on the "KI" to get two "I".
But now there are 2 "K" on the left side and only 1 on the right, meaning you need to add a 2 to the "KCL". This makes it balanced
It’s diagram because hydrogen has one proton and you’re not talking about ions so it needs another electron to stable itself
Answer:
The pH of the solution is 1.66
Explanation:
Step 1: Data given
Number of moles HCl = 0.022 moles
Molar mass of HCl = 36.46 g/mol
Step 2: Calculate molarity of HCl
Molarity HCl = moles HCl / volume
Molarity HCl = 0.022 moles / 1 L = 0.022 M
[HCl] = [H+] = 0.022 M
Step 3: Calculate pH
pH = -log [H+]
pH = -log(0.022)
pH = 1.66
The pH of the solution is 1.66
Answer:
Explanation:
1. Particles are very far apart. <u>(Gas)</u>
2. Particles are moving quickly. (<u>Liquid</u>, <u>Gas)</u>
3. Particles can flow past each other. (<u>Liquid</u>)
4. Particles are very close together. (<u>Solid</u>)
Gas particles are very far apart from each other and move quickly. Liquid particles can flow past each other and can move quickly. Solid particles are tightly packed together.
