Answer:
Empirical formula of 81.8 carbon and 18.2 hydrogen
Steps
- Find the empirical formula of a compound that has 81.8% of Carbon (C), 18.2% of Hydrogen (H).
- Divide by fractional component of each mole value: C=1.5354936431103, H=4.0709872862205Round to closest whole numbers: C=2, H=4
<h3> Combine to get the empirical formula: C2H4</h3>
Carbon dioxide + water → glucose + oxygen + water
Answer: Stressors

it can deplete aquifers include changes in precipitation and snowmelt patterns
Ammonia is NH3, meaning there are three bonds. All three bonds are between nitrogen and hydrogen, one each per hydrogen atom. If dissolved in water, they can also be called ammonium hydroxide. (NH4OH)
The new combination is called a mixture.
In mixtures, since the substances are not chemically combined together, they still remain their own physical and chemical properties, and can be separated by simple physical methods such as filtration or distillation.
On the other hand, if the two or more substances are combined where they get new properties, the new combination will be called a compound. They cannot be separated by physical methods, but chemical methods such as heating or electrolysis.
