What about it do you want answered
The water cycle does not ensure that we have water. We must HAVE water to cause water cycle.
Evaporation, then condensation, and finally precipitation.
This would happen in order.
Hope this helps!
Answer:
Percent Composition of Compounds
The percent composition (by mass) of a compound can be calculated by dividing the mass of each element by the total mass of the compound.
LEARNING OBJECTIVES
Translate between a molecular formula of a compound and its percent composition by mass
- The atomic composition of chemical compounds can be described in a variety of ways, including molecular formulas and percent composition.
- The percent composition of a compound is calculated with the molecular formula: divide the mass of each element found in one mole of the compound by the total molar mass of the compound.
- The percent composition of a compound can be measured experimentally, and these values can be used to determine the empirical formula of a compound.
- percent by mass: The fraction, by weight, of one element of a compound.
- The atomic composition of chemical compounds can be described using a variety of notations including molecular, empirical, and structural formulas. Another convenient way to describe atomic composition is to examine the percent composition of a compound by mass.
- Percent Composition by Mass
Percent composition is calculated from a molecular formula by dividing the mass of a single element in one mole of a compound by the mass of one mole of the entire compound. This value is presented as a percentage.

Heat can travel from one place to another in three ways: Conduction, Convection and Radiation.
Equilibrium concentration of SO3=1.7M
Equilibrium concentration of SO2=0.070 M
Equilibrium concentration of NO2=1.3 M
Equilibrium constant is given as=10.8
The equilibrium reaction is given as:
SO2(g)+NI2(g)⇌NO(g) +SO3(g)
Keq= ([NO][SO3])/([SO2][NO2])
To calculate concentration of NO rearranging the above equation will give:
NO=Keq*[SO2][NO2]/[SO3]
NO=(10.8*0.070*1.3)/1.7
= 0.578M
So concentration of NO will be 0.578M
