Missing question: Write the net ionic equation for the precipitation reaction that occurs when aqueous solutions of ammonium carbonate and cobalt(II) bromide are combined.<span>Balanced chemical reaction:
(NH</span>₄)₂CO₃(aq) + CoBr₂(aq) → CoCO₃(s) + 2NH₄Br(aq).
Net ionic reaction:
2NH₄⁺(aq) + CO²⁻(aq) + Co²⁺(aq) + 2Br⁻(aq) → CoCO₃ + 2NH₄(aq)+ 2Br(aq).
or CO²⁻(aq) + Co²⁺(aq) → CoCO₃(s).
The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.
the answer is :the concentration the chemicals in the solution because the more ions there are in the solution the higher the conductivity also the more ions there are in the solution the stronger the electrolyte
Hey there!
Kinetic energy means that something is in motion.
Therefore, the answer would be B. Bird in flight because it’s the only choice that suggests is moving.
Hope this helps!
God bless ❤️

The monomers that react together to form polyurethane polymer are diisocyanate and diol.
<h3>
What are polymers?</h3>
- Polymers are a class of natural or synthetic substances
- It is made up of small units called monomers arranged in a repeated pattern to form large molecules called macromolecules
- Cellulose and resins are examples of natural polymers
- Polyethylene and polychloroprene are examples of synthetic polymers.
Polyurethane polymer is made up of monomers diisocyanate and diol. It is mostly used in home furnishing in flexible form. The structures of monomers are as follows:
