What is the charge on the phosphorus atom in the polyatomic ion: PO4-3

Chemistry
1 answer:
oee [108]3 years ago
3 0

+5

Explanation:

  The given radical is                 PO₄³⁻

To solve this problem, we need to understand what oxidation number entails.

The extent of the oxidation of each atom is expressed by the oxidation number.

Here are some rules for assigning them:

  • Elements in an uncombined state or elements that combines with one another, their oxidation number is zero.
  • The charge on an ion is its oxidation number
  • In an neutral compound, algebraic sum of all the oxidation numbers of all atoms is zero.
  • In a radical, the algebraic sum of all the oxidation numbers of the ions is equal to the charge on them.

Oxygen is known to have an oxidation number of -2;

                       

                          PO₄³⁻

 P + 4(-2) = -3

 P -8 = -3

  P = -3 + 8 = +5

The charge on phosphorus is +5

29. What is E for a system which has the following two steps:
jasenka [17]

Answer:

Zero

Explanation:

Recall that;

E = q + w

Where;

q = heat, w = work done

When heat is absorbed by the system q is positive

When heat is evolved by the system q is negative

When the system does work, w is negative

When work is done on the system w is positive

Step 1

ΔE1= 60 KJ + 40 KJ = 100KJ

Step 2

ΔE2= (-30 KJ) + (-70 KJ) = (-100) KJ

ΔE1 + ΔE2= 100KJ + (-100) KJ = 0KJ

Answer: A substitution is a mutation that exchanges one base for another (i.e., a change in a single "chemical letter" such as switching an A to a G). Such a substitution could: change a codon to one that encodes a different amino acid and cause a small change in the protein produced.

Explanation: I know this is correct just trust me and please mark me as brainiest.
