Silver ion undergoes a change in oxidation state from $+I$ to $0$. Since silver has undergo a DOWNWARD change in oxidation state, it has been formally reduced.

On the other hand, elemental sodium has gone from $Na^0$ to $Na^+$; that is, it has been OXIDIZED.

With respect to the following reaction, which is the correct statement? $2HNO_3(aq) + 3H_2S(aq) rarr 3S(s)+2NO(g) +4H_2O$; a. both sulfur and nitrogen are reduced; b. nitrogen is reduced and sulfur is oxidized; c. oxygen is oxidized; d. this is not redox.

$2HNO_3 + 3H_2S rarr 3Sdarr +2NOuarr +4H_2O$ Can you write the redox half equations? Nitrate ion, $N(+V)$, is reduced to nitrous oxide, $N(+II)$. $HNO_3 + 3H^(+) +3e^(-) rarr NO +...

How do you balance this equation: $AgNO_3 + NaCl -> AgCI + NaNO_3$?

$AgNO_3(aq) + NaCl(aq) rarr AgCl(s)darr + NaNO_3(aq)$ Silver chloride will precipitate from solution as a curdy white because of its exceptional insolubility in water. The other materials are along for...

How do you balance and translate this reaction: $Cu(s) + AgNO_3(aq) -> Cu(NO_3)_2(l) + Ag(s)$?

$"Cu(s) + 2AgNO"_3("aq")"$$rarr$$"Cu(NO"_3)_2("aq") + "2Ag(s)"$ This chemical equation means: One mole of solid copper plus two moles of aqueous silver nitrate produce one mole of copper(II) nitrate plus two moles...

What kind of chemical reaction is $AgNO_3 + NaCl -> AgCl + NaNO_3$?

The following reaction is considered as a double displacement reaction: $AgNO_3(aq)+NaCl(aq)->AgCl(s)+NaNO_3(aq)$ The displacements are: $Cl^-$ replaces $NO_3^-$ and vice versa. This reaction is under the general form of: $AB+CD->AD+CB$

What kind of chemical reaction is shown? $AgNO_3 + NaCl -> AgCl + NaNO_3$

This reaction is typically performed in aqueous solution, in which $AgCl$ is about as soluble as a brick. So we could write: $AgNO_3(aq) + NaCl(aq) rarr AgCl(s)darr + NaNO_3(aq)$ Alternatively,...

How many atoms of each element of $AgNO_3$ are in 0.15 mol of $AgNO_3$?

From 0.15mol of $AgNO_3$, we can find the moles of each element by counting how many of each element is present in the entire compound. In $AgNO_3$, there's 1...

A compound is broken down into 34.5 g of element A, 18.2 g of element B, and 2.6 g of element C. What is the percent (by mass) of each element?

$%A$ $=$ $(34.5*g)/(34.5*g+18.2*g+2.6*g)xx100%=62.3%$ $%B$ $=$ $(18.2*g)/(34.5*g+18.2*g+2.6*g)xx100%=33.0%$ $%C$ $=$ $(2.6*g)/(34.5*g+18.2*g+2.6*g)xx100%=4.70%$ That is $%" element"$ $=$ $"Mass of element"/"Mass of compound"xx100%$ $"Mass of compound"$ is clearly the SUM of the constituent ....

What mass of precipitate should be obtained by the reaction between masses of $115*g$ $AgNO_3(aq)$ and $85*g$ of $BaCl_2$ where each of the components are dissolved in water?

First we need a stoichiometric equation........ $2AgNO_3(aq) + BaCl_2(aq) rarr 2AgCl(s)darr +Ba(NO_3)_2$ Now while nitrates, and most halides are soluble; silver chloride is as soluble as a brick, and precipitates...

How much $NaNO_3$ is needed to prepare 225mL of a 1.55 M solution of $NaNO_3$?

$"Concentration"$ $=$ $"Mass of stuff (g)"/"Molar mass of stuff (mol)"xx1/"Volume of solution (L)"$ The calculation gives me units of $mol*L^-1$ as required. And the product, $"Concentration"xx"Volume"$ $=$ $"Number...
