Is precipitate in water an electrolyte solution

1 answer:

4 0

When no ions are produced, or the ion content is low, the solute is a non-electrolyte. Non-electrolytes do not conduct electricity or conduct it to a very small degree. In an aqueous solution a strong electrolyte is considered to be completely ionized, or dissociated, in water, meaning it is soluble

You are given a 1.50 g mixture of sodium nitrate and sodium chloride. you dissolve this mixture into 100. ml of water and then a

Elanso [62]

When AgNO₃ solution is added to mixture of NaNO₃ and NaCl, it reacts with NaCl and gives precipitate of AgCl, which is white solid. The reaction takes place in 1:1 stoicheometric ratio as per the following balanced reaction:

NaCl + AgNO₃→ AgCl ↓ + NaNO₃. As per reaction 1 mole NaCl reacts with 1 mole AgNO₃ and gives of solid precipitate of 1 mole AgCl.

0.641 g= $\frac{0.641}{143.32}$ = 4.47 X $10^{-3}$ mole of solid AgCl is produced. This indicates 4.47 X $10^{-3}$ mole NaCl = $4.47 X 10^{-3}X58.5$ g of Nacl reacts to give 0.641 g of AgCl. So, mass percentage of NaCl present in mixture= $\frac{0.26}{1.5} X 100$ = 17.33 %.

select which of the following correctly represents the BALANCED chemical reaction for the production of HCL gas from its element

bagirrra123 [75]

Answer:

Choices 2 and 4

Explanation:

HCL is formed witthe the elements Hydrogen and Chlorine. Whatever is on the left side of the equation must match up with the right side of the equation.

2. H + Cl --> HCl (we have one hydrogen and one chlorine)

4. 2HCl --> H2 + Cl2 (since the two is distributed to both the H and the Cl, H has 2 and Cl has two on the left side AND on the right side of the equation)

The most well-known biogenic d-elements

galina1969 [7]

Answer:

Zn, Cu, Fe, Mn, Co, Mo

Explanation:

Biogenic elements are chemical elements constantly present in organisms and having definite biological significance(Bowen, 1966).

There are many of these biogenic elements in nature. Among the elements of the d-block, Zn, Cu, Fe, Mn, Co, Mo are worthy of mention among others.

Free ions of d- block metals are not found in the body. The elements are present in the form of bioinorganic complexes of the respective metals. They commonly exist as co-factors of proteins that carry out essential biological functions.
