It evaporates as the CO2 transitions from solid to gas form.
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.
Metals are placed in one spot,the nonmetals are placed in another spot,And lastly the metalloids are seperated
The answer is: C) MgO + H2O.
Balanced chemical reaction: MgO + H₂O → Mg(OH)₂.
Synthesis reaction is a type of reaction in which multiple reactants combine to form a single product.
In this chemical reaction magnesium oxide and water react anf form magnesium hydroxide.
Other examples are not synthesis reactions.
Answer:
2.83 × 10²² molecules.
Explanation:
Using the formula below to calculate the number of moles of Naphthalene:
mole = mass/molar mass
Where;
mass = 6.00g
Molar mass = 128.18 g/mol
mole = 6/128.18
mole = 0.047mol
To calculate the number of molecules of naphthalene in the mothballs, we multiply the number of moles (n) by Avagadro's number i.e.
number of molecule = n × 6.02 × 10^23
number of molecules = 0.047 × 6.02 × 10^23
= 0.283 × 10²³
= 2.83 × 10²² molecules.
