1) 800 mL of 0.025 M Pb(NO3)2 is mixed with 500 mL of 0.030 M K2CrO4. Calculate the grams of PbCrO4 that form. I am confused on how to do this I got the answer it should be 4.85 g PbCrO4, but I would want to know how to get that. And also Limiting reactan...

3) 0.3382 g of an unknown diprotic acid, when dissolved in water, required 32.34 mL of 0.1046 M KOH to reach the endpoint. Calculate the molar mass of the unknown acid. Also, for this problem I keept getting 99 close to 100 g/mol, but the answer has to be...

In a hydraulic lift, the radii of the pistons are 2.93 cm and 10.1 cm. A car weighing W = 11.0 kN is to be lifted by the force of the large piston. (a) What force Fa must be applied to the small piston? N (b) When the small piston is pushed in by 10.4 cm,...

A tire with an inner volume of 0.0250 m3 is filled with air at a gauge pressure of 30.3 psi. If the tire valve is opened to the atmosphere, what volume outside of the tire does the escaping air occupy? Some air remains within the tire occupying the origin...

A 34 g glass thermometer reads 21.6°C before it is placed in 135 mL of water. When the water and thermometer come to equilibrium, the thermometer reads 38.7°C. What was the original temperature of the water? I need help on this please could someone please...

A 34 g glass thermometer reads 21.6°C before it is placed in 135 mL of water. When the water and thermometer come to equilibrium, the thermometer reads 38.7°C. What was the original temperature of the water? -.135(4186)(Tf-38.7)=.034(840)(Tf-21.6) =-565.1...

An arrangement of two pulleys, as shown in the figure, is used to lift a 49.6-kg mass a distance of 3.70 m above the starting point. Assume the pulleys and rope are ideal and that all rope sections are essentially vertical. (a) What is the mechanical adva...

You are on Mars and would like to send a probe into space so that it does not fall back to the surface. What minimum launch speed do you need? (The mass of Mars is 6.42x10^23 kg and the radius of Mars is 3.40x10^6 m) km/s Please someone also help me on th...

Plz plz answer this question..... I need this immediate.... "what is ment by the energy-mass relationship?explain it with the help of examples.....

Can somebody solve this system of euation :2^x+3^y=17 2^x+2+3^y+1=5

Thank you for your help and time!

Thanks; I really appreciate it!

Thanks for your help, I really appreciate it! The only thing I was wondering about is part b) it says its wrong i know it's 3.02 cm, but the answer has to be in mm i got that that would be 30.2 mm, but still its wrong can you please say why I am getting i...

Thank you!

Thank you Damon and Bobpursley. I really appreciate it.

I got 15.43 degree Celsius but its wrong. I don't know why please help. Thank you!

This is how I did it: (.034)(840)(21.6-38.7)+135(4186)(Ti-38.6)

there is a mass hanging down through a pulley and the at the right there is another pulley and than the rope is at the left and F force applied I don;t know how to explain it n i cant paste it
