Answer:
moles Fe₂O₃ = 0.938 mole
Explanation:
Convert given data to moles, solve in terms of moles by reaction ratios in balanced equation. After obtaining answer in moles, convert to needed dimension. In this case, no conversions are needed.
4Fe + 3O₂ => 2Fe₂O₃
105g/56g·mol⁻¹
= 1.875 mol Fe => => => => => => 2/4(1.875 mol Fe₂O₃) = 0.938 mol Fe₂O₃
Answer:
1. mixture
2. Homogenous
Explanation:
Copper II chloride is a compound because it consists of elements that are chemically combined together. When a solute in this case, copper II chloride is mixed with water- a solvent, the result is a homogenous mixture.
Homogenous substances are formed when a solute and a solvent combine, resulting in a mixture with uniform properties. Mixtures can be separated using relevant separation techniques.
<h3><u>Answer;</u></h3>
El Nino
<h3><u>Explanation</u>;</h3>
- El Nino is a weather pattern that begins as a result in an increase in the water temperature at the surface of the Pacific ocean that produces a warm current.
- It is a climate pattern that describes the unusual warming of surface waters in the eastern tropical Pacific Ocean.
- It has an impact on ocean temperatures, the speed and strength of ocean currents together with the health of coastal fisheries. Its events occur irregularly at two- to seven-year intervals.
Answer:
5 m/s 2
Explanation:
if the car moved from 00 to 1-5 then to 2_10 you can know that it is going up in velocity but 5 a second so 5 m a second. hope this helps
