PH + pOH = 14
pH = 14 - pOH
pH = 14 - 8.7
pH = 5,3
This solution is <u>acidic</u>.
If pH<7 - acidic
If pH=7 - neutral
If pH>7 - basic
Answer:
An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. 17.5 “Temperature and Reaction Rate”).
Explanation:
Answer:I’m not 100% sure but I think it’s the first answer.
Explanation:
The pressure would increase as the molecules are pushing out word more and more, leading to more space being taken and more pressure. But then again, I’m not sure. I’m just a freshman with below average grades.
Answer: Fluorine
Explanation: Fluorine has an oxidation state of -1, meaning it gains 1 electron in chemical bonds, forming a negative ion. Magnesium has an oxidation state of +2, nitrogen has -3, and lithium has an oxidation state of +1.
Answer:
[MA4B2]2+
Explanation:
Octahedral species are species that has a coordination number of of six. This means that six ligands are attached to the central metal atom/ion.
For any octahedral specie to exhibit geometrical or cis-trans isomerism, it must have the formula EX2Y4 as in [MA4B2]2+, hence the answer above.
