To measure the amount of chlorine in a well-boring fluid, an analytical chemist adds 0.1600 m silver nitrate (agno3) solution to a 46.00 g sample of the fluid and collects the solid silver chloride (agcl) product. when no more agcl is produced, he filters, washes and weighs it, and finds that 1.46 g has been produced.
the balanced chemical equation for the reaction is:
cl^- (aq) + agno3(aq) > agcl(s) + no3^- (aq)
1. what kind of reaction is this?
o precipitation o acid-base o redox
2. if you said this was a precipitation reaction, enter the chemical formula of the precipitate.
3. if you said this was an acid-base reaction, enter the chemical formula of the reactant that is acting as the base.
4. if you said this was a redox reaction, enter the chemical symbol of the element that is oxidized.
5. calculate the mass percent of cl in the sample. be sure your answer has the correct number of significant digits.

Precipitation reaction. AgCl.

0.785%

Explanation:

Let's consider the following reaction.

Cl⁻(aq) + AgNO₃(aq) → AgCl(s) + NO₃⁻(aq)

This is a precipitation reaction, in which AgCl(s) is the precipitate.

We can establish the following relations:

The mass of Cl⁻ that produced 1.46 g of AgCl is:

The mass percent of Cl⁻ in the sample is:

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)
