what happens when NaF reacts with AgNO3 and with Pb(NO3)2
What happens KCl reacts with AgNO3 and with Pb(NO3)2
What happens when KBr and KI also both react with those same two reagents
colors and names of precipatates would help
Thanks A Lot

Is there any way of determining this answer? (like a trend on the table or just how would you do it?

If KBr, C2H5OH, C2H6, and He are arranged in order of increasing boiling point, the list is
a. He < C2H5OH < C2H6 < KBr
b. KBr < C2H6 < C2H5OH < He
c. He < C2H6 < C2H5OH < KBr
d. KBr < C2H6 < He < C2H5OH
e. C2H5OH < C2H6 < He < KBr

A real estate agency is interested in comparing the average family
incomes in two residential neighborhoods. Independent random
samples consisting of 7 families from each neighborhood were
selected. The following sample data represent family income in
thousands of dollars:
Neighborhood
1: 86.5 49.2 54.0 47.0 60.6 57.1 29.3
2: 58.8 30.4 38.0 48.5 46.0 32.7 34.5
In this problem, we want to make inferences about:




a. one mean

b. comparing means of dependent samples

c. difference of two independent means

d. one proportion

e. comparing two independent proportions

f. comparing proportions with dependent samples

The air pressure above the liquid in an open container is 1.12 atm. The depth of an air bubble in the liquid is 35.2 cm (measured from the middle of the air bubble to the top of the liquid). The liquid's density is 831 kg/m^3. Determine the air pressure in the bubble suspended in the liquid (in Pa). Acceleration of gravity is 9.8 m/s^2.

My ans. thus far that are WRONG:
127167 Pa
114300 Pa
116.353 Pa

Suppose that we were going to conduct a study to determine if there is an increased risk of getting lung cancer based on whether the person eats strawberries several times a week. In our eats strawberries regularly group(1), we find than 5 out of 2000 get lung cancer. In our non strawberry eating regular group(2), we find that 5 out of 1000 get lung cancer. What is the sample relative risk? (Give to one decimal place.)
