14.7 is the right answer plus 86
Answer:
A.
The moon's gravitational pull on Earth causes water to bulge on two sides of the Earth.
Answer:
Explanation:
Group one elements are alkali metals. All alkali metal have one valance electron. They loses their one valance electron and from cation with charge of +1.
Charges on group one.
Hydrogen = +1
Lithium = +1
Sodium = +1
Potassium = +1
Rubidium = +1
Cesium = +1
Francium = +1
Group two elements are alkaline earth metals. All alkaline earth metal have two valance electron. They loses their two valance electron and from cation with charge of +2.
Charges on group two.
Beryllium = +2
Magnesium = +2
Calcium = +2
Strontium = +2
Barium= +2
Radium = +2
Group 13 elements are boron family. All elements have three valance electrons. They loses their three valance electron and from cation with charge of +3.
Charges on group 13.
Boron = +3
Aluminium = +3
Gallium = +3
Indium = +3
Thallium= +3
Group 13 elements are also shows +1 charge by losing one valance electron.
Answer:
There are 1.8 moles of aluminum.
Explanation:
To solve this problem we need to convert moles of pyrophillite (Al₂Si₄O₁₀(OH)) into moles of aluminum (Al):
- In one mol of Al₂Si₄O₁₀(OH) there are two moles of Al.
With the above information in mind we can now <u>do the conversion</u>:
- 0.900 moles Al₂Si₄O₁₀(OH) *
= 1.8 mol Al
Thus the answer is that there are 1.8 moles of aluminum.
the answer for your question is B. Electromagnetic. because electric charge is the physical property that causes it to experience force when it is placed in a electromagnetic field the electric charge is carried by subatomic particles which causes the movement of the magnetic force
