Answer:

okay so lets say i drop a ball that weighs 2 pounds off a building and a ball that ways 1 pound off the building at the same time the lighter ball would hit the ground first because its lighter and so they heavier it is the slower it drops the lighter it is the faster it drops

Mutations that neither benefit nor harm the organism have effect on the organism's survival.
nalin [4]

No mutations that neither benefit nor harm the organism has no effect on the organism's survival.

Explanation:

The neutral mutations do not cause any effect on the organism they occur. They are called silent point mutations because they do not code for the amino acid change in the proteins.

They have no effect on the organism's survival neither beneficial nor harmful effect.

The neutral mutations do not affect the process of Natural selection.

Which of the following statements about elements in their compounds is false?
soldier1979 [14.2K]

Answer:

<h3>answer is A some second row elements may have 7 or fewer valance electron</h3>

Explanation:

<h3>because as we know second row elements are from Li up to Ne; their atomic number is from 3 - 10 and when we work their electron configuration only the inert gas neon have 8 valance electrons ; the others have 7,6,5,4,3,2,1 from F up to Li respectively so the statement is true </h3><h3>other alternatives like b it is not true because there is one element only having 8 valance electrons so it is not true</h3><h3>D and C are not true because outer most shell cannot occupey more than 8 electrons because of that those elements cannot have more than 8 valance electrons</h3>

How many total moles of ions are released when each of the following dissolves in water?
geniusboy [140]

The answer is 3 mol of ions

<h3>What is the purpose of nickel bromide?</h3>

The inorganic compounds having the chemical formula NiBr2(H2O)x are known as nickel(II) bromide. For the anhydrous substance, x can be 0; for the three known hydrate forms, x can be 2, 3, or 6. The anhydrous substance is a yellow-brown solid that dissolves in water to form a blue-green hexahydrate.

The structure of nickel bromides changes depending on the degree of hydration. The nickel(II) ion has an octahedral molecular geometry in all of these circumstances. Similar formations are seen in nickel bromide aqueous solutions.

Determine the theoretical yield of P2O5, when 3.07 g of P reacts with 6.09 g of oxygen in the following chemical equation 4 P+5O
icang [17]

Answer:

7.03g

Explanation:

4P + 5O2 → 2P2O5

Let us convert the mass given to mole. This can be achieved by doing the following:

Molar Mass of O2 = 16x2 = 32g/mol

Mass of O2 = 6.09g

Number of mole = Mass /Molar Mass

Number of mole of O2 = 6.09/32 = 0.19mol

Molar Mass of P = 31g/mol

Mass of P = 3.07g

Number of mole of P = 3.07/31 = 0.099mol

Let us determine the limiting reactant and the excess reactant

From the equation,

4moles of P required 5moles of O2.

Therefore, 0.099mol of P will require = (0.099 x 5)/4 = 0.12mol

From the above illustration, we see clearly that not all the O2 reacted as the number of mole of O2 obtained from the question is 0.19mol. This means that O2 is the excess reactant and P is the limiting reactant.

Note: the limiting reactant is always used to obtain the yield of any reaction.

Now we can obtain the theoretical yield of P2O5 as follows:

4P + 5O2 → 2P2O5

Molar Mass of P = 31g/mol

Mass of P from the equation = 4x31 = 124g

Molar Mass of P2O5 = (31x2) + (16x5) = 62 + 80 = 142g/mol

Mass of P2O5 from the equation = 2 x 142 = 284g

From the equation,

124g of P produced 284g of P2O5.

Therefore, 3.07g of P will produce = (3.07x284)/124 = 7.03g of P2O5.

Therefore, the theoretical yield of P2O5 is 7.03g
