Density is not a chemical property. It is a physical property.Electromotive force, Flammability and pH are chemical properties.
Answer:
15.4 mol CO₂
Explanation:
5.12 mol C₃H₈ × (3 mol CO₂ / mol C₃H₈) ≈ 15.4 mol CO₂
Answer:
The reactants are MgF₂ and Be.
This is a single displacement reaction.
Explanation:
Chemical reactions are written like this:
reactant + reactant => product + product
There may be more or less reactants and products on each side, separated by + the plus sign. The reactants are on the left and the products are on the right.
In the equation BeF₂ + Mg => MgF₂ + Be, <u>the products (on the right side) are MgF₂ and Be</u>.
Since the total reactants are equal to the total products, every element that you see on the left must also appear on the right. On the left, the question gave you the elements "Be", "F" and "Mg". On the right, "Be" was missing, so it must be the missing product.
This is a <u>single displacement reaction</u> because one element that was in a pair was replaced by another.
All single displacement reactions look like this:
AB + C = AC + B An element that was paired up switched places with another element that was not paired up.
In this reaction, "Be" was displaced. It started the reaction paired up with "F", but it was replaced by "Mg".
Answer:
A
Explanation:
The pesticides and chemicals in are food could get us seriously sick and cause food poisoning. We are hurting our water by dumping sewage water into lakes and rivers did you ever think that someday a river or a lake will mix in with the ocean.
Answer:
no, food is not a fuel because it just give energy to do many activities but it will not provide any fuel only the dead and decaying material which berries under the soil then after a long years it becomes fossil fuel
