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).

If liquid carbon disulfide reacts with 450 mL of oxygen to produce the gases carbon dioxide and sulfur dioxide, what volume of e
ivolga24 [154]

If excess carbon disulfide reacts with 450 mL of oxygen, 150 mL of carbon dioxide and 300 mL of sulfur dioxide gases would be produced respectively.

<h3>Stoichiometric calculation</h3>

The reaction between liquid carbon disulfide and oxygen is represented by the equations below:

CS_2 + 3O_2 -- > CO_2 + 2SO_2

The mole ratio of oxygen to carbon dioxide and sulfur dioxide produced is 3:1:2.

Thus, for 450 mL oxygen, 1/3 x 450 = 150 mL of carbon dioxide will be required.

Also for 450 mL of oxygen, 2/3 x 450 = 300 mL of sulfur dioxide will be required.

If aqueous solution of lead (ll) nitrate and sodium sulfate, which insoluble precipitate is formed
forsale [732]

Answer:

Lead(II) sulfate

Explanation:

This looks like a double displacement reaction, in which the cations change partners with the anions.

The possible products are

Pb(NO₃)₂ (aq)+ Na₂SO₄(aq) ⟶PbSO₄(?) + 2NaNO₃(?)

To predict the product, we must use the solubility rules. Two important ones for this question are:

  1. Salts containing Group 1 elements are soluble.
  2. Most sulfates are soluble, but PbSO₄ is an important exception.

Thus, NaNO₃ is soluble and PbSO₄ is the precipitate.

Anna35 [415]

Answer: A. Cytoplasm

Explanation: Cytoplasm is a jelly, like material that fills up the remaining space in the cell. It is also responsible in making the shape of the cell. Without it, other parts of the cells or the organelles cannot make its function because it serves as the hallway of the transportation of the nutrients needed by each cell.
