Answer:

The answer to your question is a balanced equation

Explanation:

Chemical formulas are extremely useful in chemistry and these formulas follow the law of proportions but not the law of conservation of matter.

Coefficients indicate that an equation is balanced if these numbers are in proportion but it is not the answer.

Balanced equation is a feature of the law of conservation of matter.

Subscripts are necessary for chemical reactions but they are not a feature of the law of conservation of matter.

What are the spectator ions in this equation?

dangina [55]

The given question is incomplete. The complete question is :

What is the net ionic equation for the following reaction?

$H_2CrO_4+Ba(OH)_2$

Answer : The spectator ions are $Ba^{2+}$ and $CrO_4^{2-}$

Explanation:

Neutralization is a chemical reaction in which an acid and a base reacts to form salt and water.

Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.

The given chemical equation is:

$2H^+(aq)+CrO_4^{2-}(aq)+Ba^{2+}(aq)+2OH^-(aq)\rightarrow Ba^{2+}(aq)++CrO_4^{2-}(aq)+H_2O(l)$

The ions which are present on both the sides of the equation are barium and chromate ions. and hence are not involved in net ionic equation.

Hence, the net ionic equation is $H^++OH^-\rightarrow H_2O$

Which best describes the effect of jj Thomson discovery

beks73 [17]

JJ Thomson discovered electrons using the cathode ray. Electrons are negatively charged particles that orbit around the nucleus of an atom. Finding out that there was a negative charge to balance out the positive charge. This later helped develop Hund's Rule and the Pauli Exclusion Principle.

A sodium bromide solution is added to a beaker containing aqueous chlorine. What would happen?

Darya [45]

Answer:

See detailed explanation.

Explanation:

Hello!

In this case, for the described chemical reaction, we can proceed as follows:

A) For the complete chemical reaction we note down every reacted and produced species as well as the proper balancing process:

$2NaBr(aq)+Cl_2(aq)\rightarrow 2NaCl(aq)+Br_2(g)$
