this is my work, would you please check my work, thank you!
a liter of a solution saturated at 225 degree C with calcium oxalate, CaC2O4, is evaporated to dryness, giving a 0.0061 gm residue of CaC2O4. calculate the concentrations of the ions, and the molar solubility and solubility product constant for this salt at 25 degree C.
(o.oo61mg)(1/1000mg x 128g) = 4.8E-8M
ksp= (4.8E-8)(4.8E-8)= 2.3E-15
answer the above question, using a solution of 0.15M CaCl2 as the solvent instead of pure water.
(-2x^2y)^3*(5xy^3)^2=(-2x^2y)^3 = -8 x^6 y^3 *Please check my work. What did you do with the (5xy^3)^2 part. The first part you did ok. But you can't just throw away part of the equation. I don't get that part.What do I do there.?
A cannon is fired from a cliff 190 m high downward at an angle of 38o with respect to the horizontal. If the muzzle velocity is 41 m/s, what is its speed (in m/s) when it hits the ground? Please check my work. I think it’s
Can someone please help me with this one? Solve (5x+4)^1/2-3x=0 Just so you know, it is to the 1/2 power. Add 3x to both sides of the equation, then square both sides. That should enable you to gather terms and factor. Yeah,
Please check my work- what is the molarity of a solution that has 34.85 g of Potassium sulfate dissolved in one liter of solution? so K2(SO4) molar mass is 174.26, 34.85 grams x 1mol/174.26 than divided by 1 Liter equals .19998
A 800kg , light-weight helicopter ascends from the ground with an acceleration of 3.00m/s2 . Part A Over a 6.50s interval, what is the work done by the lifting force? Part B What is the work done by the gravitational force? Part C
In what way is Islam most likely to impact Muslims during work days? 1)They must leave work early 2)They will not participate in leisure activities after work 3)They can not have certain jobs 4)They need to pause during their work
Part 1 A 15.6 kg block is dragged over a rough, hor- izontal surface by a constant force of 72.2 N acting at an angle of angle 34.8 above the horizontal. The block is displaced 24.6 m and the coefficient of kinetic friction is

Check this please :D Which of the following three statements used to describe work are true: i)Work is done only if an object moves through a distance ii)Work is done only if energy is transferred from one form to another iii)Work
