Answer:
No
Explanation:
The equation does not obey the law of conservation of mass by not accounting to the total number of Chlorine in the products.
Law of conservation of mass states that in ordinary chemical reactions, matter can neither be created nor destroyed but can be converted from one form to another.
The equation presented was
CuCl₂ + Na₂S → CuS + NaCl
1. The total number of copper in the reactant is equal to number of Cu in product
2. Numbe of Chlorine in the reactant is 2 while in the product is just 1. Not accounted for.
3. Number of sodium on the reactant is not equal to number of sodium on the product I.e 2 on the reactant and just 1 on the product.
4. Number of sulfur on the reactant is equal to number of sodium on the product.
Correct chemical equation
CuCl₂ + Na₂S → CuS + 2NaCl
Answer:
I think the answer is Hydro sphere
Explanation:
Earth includes four components
Atmosphere
Biosphere
Hydro sphere
Geosphere
Here Hydro sphere is the goal of question
Best Answer: producers use nutrients in the soil > consumers eat the producers, obtaining the energy and nutrients that the plant took > the consumer dies and is decomposed by a decomposer (usually decomposing bacteria), which replaces the nutrients back into the soil > producers use the nutrients in the soil.
now put that into your own words; if you cant, try drawing pictures to help you :) that might help you revise too, but remember to add info underneath, otherwise you might not understand it when you come back to it later
The crude oil is heated in a process of fractional distillation (note: you can research this online if you require more detail) and this process causes different hydrocarbons to condense at different heights up the distillation column. They will therefore run down the side of the column and into different areas depending on their boiling point.
