Answer:
See below
Explanation:
propane mole weight = 44 gm / mole
100 gm / 44 gm / mole = 2.27 moles
From the equation, 5 times as many moles of OXYGEN (O2)are required
= 11.36 moles of oxygen
at <u>STP</u> this is 254.55 liters of O2 (because 22.4 L = one mole) and
Using oxygen as 21 percent of air means that
.21 x = 254.55 = x = <u>1212.12 liters of air required </u>
The answer is package c because each cd would cost $1.87, which is the lowest price
Answer:

Explanation:
Hello,
In this case, the molecular chemical reaction is written as:

In such a way, considering the net ionic notation and the solid yielded copper (I) bromide, we write:

Whereas ammonium and sulfate ions are spectator ions, therefore the net ionic equation is:

Regards.
Redox is a chemical reaction in which the oxidation states of atoms are changed. Any such reaction involves both a reduction process and a complementary oxidation process, two key concepts involved with electron transfer processes.
