If pH is less than seven (pH<7), solution is acidic.
If pH is equal seven (pH = 7), solution is neutral.
If pH is greater than seven (pH > 7), solution is basic.
Some examples:
1) Acidic - gastric juices pH 1, lemon juice pH 2.2, tomato juice pH 4.
2) Neutral - salt solution pH 7.
3) Alkaline - baking soda pH 9, bleach pH 13.
pH is a numeric scale used to specify the acidity or basicity of an aqueous solution.
<h3>Sulfate takes two Copper atoms and gains negative valence charge,whereas the Copper gains a positive valence charge.The Sulfate is bonded in covalent bonds of polarity, Oxygen having the higher electronegativity, and therefore pulling the electrons closer to it's nucleus than to Sulfur's nucleus.</h3>
Answer: A
Explanation:
Hydrolysis reactions break down not only feldspars but many other silicate minerals as well, amphiboles, pyroxenes, micas, and olivines.
Mutation affect a species ability to survive and reproduce. Mutations can expand the life span of a species by keeping them hidden from predators which would also increase reproduction. If exposed to other wildlife, those numbers could decrease.
Answer:
4.89 mol
Explanation:
Step 1: Write the balanced equation
This is a double displacement reaction.
3 CaSO₄ + 2 AIP ⇒ Ca₃P₂ + AI₂(SO₄)₃
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of CaSO₄ to AlP is 3:2.
Step 3: Calculate the moles of AlP needed to react with 7.33 moles of CaSO₄
We will use the previously established molar ratio.
7.33 mol CaSO₄ × 2 mol AlP/3 mol CaSO₄ = 4.89 mol AlP
