Answer:
Word equation: <u>Potassium chlorate → Potassium chloride + Oxygen</u>
Chemical equation: <u>KClO₃ → KCl + O₂</u>
Explanation:
<em>This is decomposition reaction so there will only be one reactant, which is potassium chlorate.</em>
The chemical equation will be:
KClO₃ → KCl + O₂
The balanced equation would be:
2KClO₃ → 2KCl + 3O₂
The word equation will be:
Potassium chlorate → Potassium chloride + Oxygen
Answer:copper(II) sulfate, CuSO4> 2-pentanol, C5H11OH> methane, CH4>propane, C3H8.
Explanation:
Solubility depends on the ability of solute to interact effectively with a solvent. If water is the solvent, it interacts effectively with ionic substances. copper II sulphate is ionic and will be the most soluble in water, 2-pentanol, will interact effectively with water via hydrogen bonding. Between methane and propane, methane will interact better with water since it has a shorter alkyl chain than propane
Answer:
a) 64.27%
b) 58%
c) ethanol is the limiting reactant
d) ethanol is the limiting reactant
Explanation:
We have to note that the expected yield is the theoretical yield while the actual mass or amount of product formed is the actual yield.
a) theoretical yield=68.3g
Actual yield= 43.9 g
Percentage yield= 43.9/68.3 ×100
Percentage yield= 64.27%
b) theoretical yield= 0.0722 moles
Actual yield = 0.0419
Percentage yield= 0.0419/0.0722 × 100
Percentage yield= 58%
c) note that the limiting reactant yields the least number of moles of product
Ethanol will be the limiting reactant since it is not present in excess.
d) from the reaction equation;
1 mole of acetic acid produces 1 mole of ethyl acetate
0.58 moles of ethanol produces 0.58 moles of ethyl acetate
1 mole of acetic acid yields 1 mole of ethyl acetate
Hence 0.82 moles of acetic acid yields 0.82 moles of ethyl acetate
Hence ethanol is the limiting reactant.
It differs because it shows different volume of information and it gives a different point of indicanton of numbers.
Answer:
The zebra mussel is found in freshwater lakes and rivers of the Balkans, Poland, and the former Soviet Union. It was first found in the United States in Lake St. Claire, off of the eastern shore of the state of Michigan.
Biologists think the zebra mussel was picked up in a freshwater European port in the ballast water of a ship, and was later released into the water on the Canadian side of Lake St. Clair. The zebra mussel was not intentionally transported into its new ecosystem.
The zebra mussel is small, free-swimming, and easily spread by water currents, and can attach to almost any hard surface.
The zebra mussel affects an ecosystem's food web both positively and negatively. The positive effects include serving as a food source to many native fish, birds, and other animals. The negative effects include interfering with other organisms' feeding, growth, movement, respiration, and reproduction.
