First find the answer to the equation
3 • 3/4 = 9/4
Reduce the fraction to a mixed number
9/4 = 2 1/4
Now determine which 2 whole numbers it is between
2 1/4 lies between 2 and 3
Answer:
3.5
Step-by-step explanation:
Answer:
Oceans and the Sun.
Step-by-step explanation:
Lakes and the sun is also a good answer, but the question is asking which interact the <em>most</em>, which is the ocean and sun.
We can also rule out the moon since it has nothing to do with the water cycle, so the last two options are also wrong.
The answer is B.
in the original equation, CH4 + O2 → CO2 + H2O, there are:
REACTANTS: 2 carbon, 4 hydrogen, 2 oxygen
PRODUCTS: 2 carbon, 2 hydrogen and 1 oxygen.
If we change the equation to this,
CH4 + 2O2 → CO2 + 2H2O, then there are now:
REACTANTS: 2 carbon, 4 hydrogen, 4 oxygen
PRODUCTS: 2 carbon, 4 hydrogen, 4 oxygen
and thus the equation is balanced
