Option B is correct. Phosphates are formed when phosphorus reacts with Oxygen
A phosphate group is formed from the bonding of four oxygen atoms to a phosphorous atom. The chemical reaction is as shown:
P + O₄ -> PO₄
P is the symbol of phosphorus
O is the symbol of oxygen
When both elements combine, they form phosphates.
Hence we can conclude that Phosphates are formed when phosphorus reacts with Oxygen

Which one of the following is an incorrect orbital notation?
B. 4f
C. 2d
D. 3s
E. 2p
(no 'A')
The answer option which is an incorrect orbital notation is: C. 2d.
A sublevel refers to an energy level that is typically associated with the valence electrons found outside an atomic nucleus.
In Chemistry, there are four (4) main types of sublevel and these includes:
s orbital (sublevel): 3sp orbital (sublevel): 2pd orbital (sublevel): 3df orbital (sublevel): 4fHowever, it is impossible for any atom of a chemical element to have a 2d orbital because electrons are generally located in the s and p orbitals (sublevels) in the second energy level.

Use the equation Moles = Mass/Mołar Mass (Mr) to calculate the following: To make 3 moles of
Sodium (Na), how much mass do I need to weigh out?
A: 699g
B: 6.9g
C: 69g
D: 96g
Answer:
c
Explanation:
Molar mass of Na=23g/mol
amount of mole(n)=3
mass=?
therefore,n=m/M
3mol=m/23g/mol
m=23g/mol ×3mol
m=69g.

Volume of 8.625 g of sulphur di oxide at RTP in cm3
Answer:
The volume of 8.625 g of sulphur dioxide at RTP is approximately 3,230.84 cm³
Explanation:
The question requires the determination of the volume occupied by the gas based on the molar volume of a gas at STP
The given parameters of the sulphur dioxide, SO₂, gas are;
The mass of the given SO₂ gas = 8.625 g
The molar mass of SO₂ = 64.07 g/mol
The number of moles, 'n', in the given sample of SO₂ gas = Mass of SO₂/(Molar Mass of SO₂)
∴ The number of moles of SO₂ in the gas sample = 8.625 g/(64.07 g/mol) ≈ 0.134618386 moles
The molar volume of a gas at RTP is approximately 24 dm³/mole
24 dm³ = 24,000 cm³
∴ The molar volume of a gas at RTP is approximately 24,000 cm³/mole
The volume occupied by a gas at RTP = (The number of moles of the gas) × (The Molar Volume of a gas at RTP)
∴ The volume occupied by the 8.625 g of SO₂ gas at RTP = 0.134618386 moles × 24,000 cm³/mole ≈ 3,230.84 cm³
The volume occupied by the 8.625 g of SO₂ gas at RTP ≈ 3,230.84 cm³.

If 20 hits equal 1 web 1 futz equal 2 geese 10 webs equal to 1 futz How many gits are equal to 5gews?
Answer:
500 hits
Explanation:
If 20 hits equal 1 web 1 futz equal 2 geese 10 webs equal to 1 futz How many hits are equal to 5 geese?
Solution:
Given that:
20 hits = 1 web, 1 futz = 2 geese; 10 webs = 1 futz
10 webs = 1 futz; hence:
1 web = 1 web * 1 futz / 10 webs = 0.1 futz
1 web = 0.1 futz
1 futz = 2 geese; hence:
0.1 futz = 0.1 futz * 2 geese / 1 futz
0.1 futz = 0.2 geese
Therefore, 1 web = 0.1 futz = 0.2 geese
1 web = 0.2 geese
This means that 20 hits = 1 web = 0.2 geese
20 hits = 0.2 geese
5 geese = 5 geese * 20 hits / 0.2 geese
5 geese = 500 hits
