Answer:

Reactants and products

Explanation:

The reaction can be writen inthis way

6H_{2}O + 6CO_{2}⇒C_{6}H_{12}O_{6} + 6O_{2}

Here we can notice that water and carbon dioxide are combined, so they are the reactants and produce glucose and oxygen that are the products.

An oxide of P contains 50% by mass of P. Its Relative molecular mass is 64. The molecular formula of the oxide is (P=32; O=16)
anygoal [31]

Answer:

B) PO2

Explanation:

first solve empirical formula

50%of P and 50%of O

  • divide each by molecular mass

P. O

50/32. 50/16

1.5. 3.0

  • divide both by the smallest

1.5/1.5. 3.0/1.5

1. :. 2

Empirical formula=PO2

Molecular formula=PO2

(PO2)n= 64

(32+(16×2)=64

(32+32)n=64

64n=64

n= 1

If 6.96 mol of C 5 H 12 reacts with excess O 2 , how many moles of CO 2 will be produced by the following combustion reaction? C
kati45 [8]

Answer:

34.8 moles of CO₂ are produced

Explanation:

This is the reaction:

1C₅H₁₂ + 8O₂  →  6H₂O  +  5CO₂

Ratio is 1:5. We make a rule of three

1 mol of pentane can produce 5 moles of CO₂

Then, 6.96 moles of pentane may produce (6.96 .5) / 1 = 34.8 moles

Why do magnesium and oxygen need to be heated for a reaction to occur?​
Alexxandr [17]

Because flame provides a source of heat so that the magnesium metal atoms can overcome their activation energy. Activation energy is the minimum energy required in order for a chemical reaction to proceed. When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide.
