How are ions formed?

Chemistry
1 answer:
stepan [7]4 years ago
3 0

Hey there!

Your answer is c. by the transfer of one or more electrons from one atom to another.

Ions can be positive or negative. Positive ions are called cations, and negative ions are called anions.

Electrons are transferred because two atoms have a large difference of electronegativity and the electrons are shared so unequally that the electrons are completely transferred from one atom to another, forming ions.

Hope this helps!

How can forgery be used in crime
Tems11 [23]

Some bad people will tend to forge dollar bills and make fake bills, giving them to cashiers and asking for it to be split into a different amount of bills so they are given real cash and wont be caught or they will buy things, return them and be given back real money and get away with it. This is obviously a crime because it's fake.

Use the following balanced reaction to solve:
Naily [24]

Answer:  60.7 g of PH_3 will be formed.

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given volume}}{\text{Molar volume}}    

\text{Moles of} H_2=\frac{60L}{22.4L}=2.68moles

The balanced chemical reaction is

P_4(s)+6H_2(g)\rightarrow 4PH_3(g)

H_2 is the limiting reagent as it limits the formation of product and P_4 is the excess reagent.

According to stoichiometry :

6 moles of H_2 produce = 4 moles of PH_3

Thus 2.68 moles of H_2 will produce=\frac{4}{6}\times 2.68=1.79moles  of PH_3

Mass of PH_3=moles\times {\text {Molar mass}}=1.79moles\times 33.9g/mol=60.7g

Thus 60.7 g of PH_3 will be formed by reactiong 60 L of hydrogen gas with an excess of P_4

Assuming that a chemical reaction doubles in rate for each 10° temperature increase, by what factor would the rate increase if t
12345 [234]

Answer:

It'll be increased by a factor of 16...

Explanation:

After 10 C = Doubles

After 20 C = 4 Times

After 30 C = 8 Times

After 40 C = 16 Times

(The rate of reaction doubles as per 10 C rise in temperature as calculated)

WILL MARK BRAINLIEST<br> How many electrons can be held in the energy level n = 4?
anyanavicka [17]

Answer:

32

Explanation:

Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.
