K₂CrO₄(aq) + Ba(NO₃)₂(aq) = BaCrO₄(s) + 2KNO₃(aq)
2K⁺ + CrO₄²⁻ + Ba²⁺ + 2NO₃⁻ = BaCrO₄ + 2K⁺ + 2NO₃⁻
spectator ions: K⁺, NO₃⁻
Answer:
Mercury
Explanation:
mercury, and it's the only metal that normally exists on Earth as a liquid.
Answer:
A product in science is a substance that is formed when two or more chemicals react.
Explanation:
When a chemical reaction takes place, a new substance is often created from the atoms or molecules of the original substances. There are often multiple products formed in a reaction.
Answer: -
Fission creates large amounts of radioactive waste.
Explanation: -
During nuclear fission, by products are formed. These by products are radioactive in nature. They give radiation. These radiation causes a lot of harm to humans including cancer and mutations.
Thus, Fission creates large amounts of radioactive waste.
Answer:
1 and 3 only
Explanation:
When a reaction is equilibrium, its forward reaction and reverse reaction are happening at the same rate. For a reaction to have a forward reaction and reverse reaction, the reaction must be reversible. Therefore, statement #2 is incorrect. Now, since the forward reaction and reverse reaction are moving at the same rate, the rate at which products are being converted to reactants is equal to the rate at which reactants are being converted to products. This means the concentrations of the reactants and products stay constant. That means statement #3 is correct. For equilibrium to happen, the system must be closed though. If a system is closed, that means no hydrogen, iodine, or hydrogen iodide can escape the system. Therefore, statement #1 is also incorrect.
