62.3018 g/mol is the molar mass
Answer:
1) P4O10 + 6H20 → 4H3PO4
2) 1.25 moles of P4O10
3) 7.5 moles of water
Explanation:
1. Write the balanced equation for this reaction
P4O10 + 6H20 → 4H3PO4
2) Determine the number of moles of P4O10 required to produce 5.00 moles of phosphoric acid.
For 1 mole P4O10 consumed, we need 6 moles of water to produce 4 moles of H3PO4
If we get 5.00 moles of H3PO4, we'll have 5/4 = 1.25 moles of P4O10 consumed.
3) Determine the number of moles of water required to produce 5.00 moles of phosphoric acid
For 1 mole P4O10 consumed, we need 6 moles of water to produce 4 moles of H3PO4
If we have 5.00 moles of H3PO4, we'll get (6/4)*5 = 7.5 moles of water consumed.
Answer:
5.50 mil KCI * 2 mol KCIO3 / 2 mil KCI
I don’t know the answer, but my teacher gave me the steps to solve it...
Explanation:
To get a result with the best degree of precision, the
number of significant figures should be equal to the smallest number of
significant figures of the given numbers. In this case, the smallest is 3 as
given by the number 9.03 mL.
Therefore density is:
<span>11.50 g / 9.03 mL = 1.27 g/mL</span>
The three-dimensional arrangement of the atoms of the molecule is molecular geometry. The molecule of sulphur dioxide is not linear in geometry. Thus, option D is correct.
<h3>What is linear geometry?</h3>
Linear geometry is a type of molecular geometry that portrays the straight molecules that have a bond at 180 degrees and includes the central atom bonded to another two atoms through single or double bonds.
Carbon dioxide exhibits linear geometry as central carbon has sp hybridization and bonded to oxygen making them linear. Similarly, beryllium in beryllium fluoride and mercury in mercuric chloride are arranged linearly with their other two atoms.
Therefore, option D. sulphur dioxide does not have linear pair geometry but rather is a bent structure.
