Complete and balance the precipitation reactions. Include physical states. Refer to the solubility rules as necessary. precipita

Tcecarenko [31]

The balanced chemical reactions are:

$AgNO{_3}(aq) \ + \ NaCl(aq) \rightarrow \ AgCl(s) \ + NaNO_{3}(aq)\\2K_{3}PO_{4}(aq) \ + 3MgCl_{2}(aq) \rightarrow \ 6KCl(aq) \ + Mg_{3}(PO_{4})_{2}(s)$

Further Explanation:

The following reactions will undergo double displacement where the metal cations in each compound are exchanged and form new products.

For reaction 1, the compounds involved are nitrates and chlorides. To determine the states of the products, the solubility rules for nitrates and chlorides must be followed:

All nitrates are generally soluble.
Chlorides are generally soluble except AgCl, PbCl2, and Hg2Cl2.

Therefore, the products will have the following characteristics:

silver chloride (AgCl) is insoluble
sodium nitrate (NaNO3) is soluble

For reaction 2, the compounds involved are phosphates and chlorides. The solubility rules for phosphates and chlorides are as follows:

Phosphates are generally insoluble except for Group 1 phosphates.
Chlorides are generally soluble except for AgCl, PbCl2, and Hg2Cl2.

Hence, the products of the second reaction will have the following characteristics:

potassium chloride (KCl) is soluble
magnesium phosphate is insoluble

Insoluble substances are denoted by the symbols (s) in a chemical equation. The soluble substances are denoted as <em>(aq).</em>

What does the author predict about the future of the Earth's mantle? Do you support his educated guess? Use complete sentences t

Masja [62]

The earth's mantle will not change in the future because this region is safe from the intervention of human beings.

<h3>What happens in the Earth's mantle?</h3>

The transfer of heat and material in the mantle helps us to determine the landscape of Earth. Activity in the mantle moves the plate tectonics, that contributes to volcanoes, seafloor spreading, earthquakes, and building of mountains.

So we can conclude that the earth's mantle will not change in the future because this region is safe from the intervention of human beings.

Why do plant animal cells both have mitochondria?

LuckyWell [14K]

The mitochondria is the powerhouse of a cell. They are important because they are an energy factor for both plant and animal cells. They take the food you eat, and turn that as energy for the rest of the cell to use. It is critical that every cell has one to survive whether plant or animal.
