Answer: D) They share electrons

Explanation: Nonmetals under goes a bond called covalent bond. The chemical bond that requires the sharing of electron pairs is known as covalent bond. This bond is of three types namely; polar covalent, non polar covalent, and coordinate covalent.

It's is very difficult for an electron to be removed from nonmetals, that is, they exhibit high ionization energy.

So because of this characteristics, when two nonmetals bond, they share electrons instead of transferring electron.

How to balance lead and silver acetate yields lead (||) acetate and silver

arsen [322]

The given elements put into an equation using their symbols are as follows:
Pb + $AgC_{2}H_{3}O_{2}$ = $Pb(II){(C_{2}H_{3}O_{2})_2}$ + Ag

Since there are 2 Pb on the right side of the equation, you would change the coefficient of Pb on the left side to 2:
2Pb + $AgC_{2}H_{3}O_{2}$ = $Pb(II){(C_{2}H_{3}O_{2})_2}$ + Ag

Since there are 2 Acetate on the right side of the equation, you would change the coefficient of Silver Acetate on the left side to 2:
2Pb + $2AgC_{2}H_{3}O_{2}$ = $Pb(II){(C_{2}H_{3}O_{2})_2}$ + Ag

Now there are 2 Silver on the left side, so you change the coefficient of Silver on the right side to 2:
2Pb + $2AgC_{2}H_{3}O_{2}$ = $Pb(II){(C_{2}H_{3}O_{2})_2}$ + 2Ag

That is your final equation

The coefficients are 2 + 2 = 1 + 2

How many moles of sulfuric acid (H2SO4) are present in 500.0 mL of 0.15 M H2SO4 solution?

galben [10]

Answer:

Number of moles = 0.075 mol

Explanation:

Volume = 500.0 mL = 0.5 (Converting to L by dividing by 1000)

Molarity = 0.15 M

Number of moles = ?

The relationship between the quantities is given as;

Molarity = Number of moles / Volume

Number of moles = Molarity * Volume

Number of moles = 0.15 * 0.5

Number of moles = 0.075 mol

Look at this data and calculate the mean, median, mode, and range.

CaHeK987 [17]

Answer:

the median is 14 the range is 15 the mode is 14 and the mean is 12.7

Explanation:

for the median you put all numbers is order but least to greatest and figure out the middle number for range you take the smallest and the biggest number and subtract them for mode you use the most repeated number and for the mean you add all the numbers and divide by the total of numbers I hope this helped

Explain ways that organisms interact in helpful and harmful ways.

I am Lyosha [343]

Organisms are living things. Us humans are also living things, so we are helpful and harmful to other organisms. For example: we can help another human being with something, or we can help a plant/tree grow if we water it. In return, they also help us by providing us with oxygen. however, we can also be harmful to each other and the environment, for example: we can't hurt each other, or plant or animals by killing them or we can hurt insects by stepping on them. Therefore, organisms are helpful and harmful to each other.
