i cannot print my project because every time I print, there is always strips of line. :/

please help!

In a European country a bathroom scale displays its reading in kilograms. when a man stands on this scale, it reads 85.7 kg. when he pulls down on a chin-up bar installed over the scale, the reading decreases to 69.3 kg. what is the magnitude of the force he exerts on the chin-up bar?

____________________

do you just have to minus 69.3 kg from 85.7 kg and multiply it to 9.8 m/s^2?

and why?

1s2 2s1?

philippine setting..

every answer is appreciated~ :P

how to name these compound using stock method?

1.) CrSO3

2.) CrO3

3.) Cr2O3

please explain to me how do you got the answer.

thanks! =D

please answer as many as you can. and tell me how did you get the answer. thanks!

1.) molecular mass/ formula mass (in amu.) of Ca3(PO4)2

2.) The atomic masses of 6/3Li and 3/7Li are 6.0151 amu and 7.0160 amu, respectively. calculate

the natural abundances of these two isotopes. the average atomic mass of Li is 6.941 amu.

3.) calculate the molar mass of a compound if 0.372mole of it has a mass of 152g

4.) how many molecules of ethane are present in 0.334g of C2H6?

every answer is greatly appreciated!! thanks! =D

pls. answer as many as you can

1.) two metals less dense than water

2.) two metals more dense than mercury

3.) densest known solid metallic element

4.) densest known solid nonmetallic element

pls. tell me how did you know the answers..

thanks! I appreciate all answers.

=D

pls. answer as many as you can.

1.) identify a nonmetal whose name also ends with "-ium"

2.) Describe the changes in properties (from metals to nonmetals or from nonmetals to metals) as we move (a) down a periodic group and (b) across the periodic table.

3.) group these elements in pairs that you would expect to show similar chemical properties: K, F, P, Na, Cl, and N.

4.) identify the following as elements or compounds: NH3, N2, S8, NO, CO, CO2, H2, SO2.

5.) Give the number of protons and electrons in each of the following common ions: K+, Mg^2+, Fe^3+, Br-, Mn^2+, C^4-, Cu^2+, Na+, Ca^2+, Al^3+, Fe^2+, I-, F-, s^2-, O^2-, N^3-

I don't know how to answer these questions. I appreciate every help.

thanks!

=D

1.) light years to miles

2.) yard to centimeter

3.) centimeter/seconds to feet/seconds

4.) cubic meter to liters

thanks =D

i'm really not that good in numbers. please help.

im kinda confuse.

how to grow and work out my salvation?
