Answer:
Electromagnetism is the study of the electromagnetic force, one of the four fundamental forces of nature. It includes the electric force, which pushes all charged particles, and the magnetic force, which only pushes moving charges.It is used in many electrical appliances to generate desired magnetic fields. It is even used in a electric generator to produce magnetic fields for electromagnetic induction to occur.
Explanation:
tell me if this helped, ill try and explain better
Answer: 0.123 M
Explanation:
According to the neutralization law:
where,
= molarity of 
solution = ?
= volume of solution = 15.00 ml
= molarity of 
solution = 0.100 M
= volume of solution = 18.44 ml
= valency of = 1
= valency of = 1
Therefore, the concentration of the unknown HBr solution is 0.123 M
Following are the pair of elements that result in an ionic compound
Option A and B
<u>Explanation:</u>
- Ionic compounds are defined as the compound that consists of ions held by two atoms of differently charged ions.
- These compounds have a positive charge of ions called cations and a negatively charged element is anions.
- In the above options, we shall say that the atoms such as Ca and K both result in cations as they release an electron to become a positive ion.
- Also, Cl and S both result in anions as they attract more electron to form negative ions.
- These positive and negative ion together results in an ionic compound.
Answer:
Explanation:
7.706 g of CO₂ will contain 12 x 7.706 / 44 g of C
= 2.1 g of C .
This will be contained in 3.256 g of isopentyl acetate
3.156 g of H₂O will contain 2 x 3.156 / 18 g of H
= .351 g of H
This will be contained in 3.256 g of isopentyl acetate
Rest will be oxygen
amount of oxygen in 3.256 g of isopentyl acetate
= 3.256 - ( 2.1 + .351 )
= .805 g
ratio of C , H , O in isopentyl acetate
= 2.1 g : .351 g : .805 g
2.1 / 12 : .351 / 1 : 0.805 / 16 ratio of moles
= .175 : .351 : .05 ratio of moles
= 3.5 : 7.02: 1
= 7 : 14 : 2
empirical formula of isopentyl acetate
= C₇ H₁₄ O₂ .
Answer:- 
Explanations:- It's a double replacement reaction where a precipitate of silver(I)bromide is formed. A dpuble replacement reaction in general looks as AB + CD \rightarrow AD + CB
To balance the equation we need to multiply gold compounds on both sides by 2 and the balanced equation is..
