just wanted to say thankyou :)

sodium chloride (relative molecular mass = 58.5) had a solubility of 36.0 g per 100g of water. the density of the solution is 1.13 g/ml. which of the following calculations would give te solubility in moles per liter? A) 36.0 x 10/58.5 b) 36.0 x 10 x 1.13...

can anyone explain to me why LiCO3 is NOT a lithium compound? and what exactly is needed for lithium compounds?? thanks!

Solve for x, correct to one decimal place. It`s a right angle triangle. The height for the triangle is 4 cm with a 48° angle. The bottom of the triangle is an x. I got the answer 3.3 cm, is this correct? Any help would be appreciated. Thanks!

Please help, I’m stuck and need help with these! 1. The point (1, 1) is the image under the translation (x, y) --> (x + 3, y - 3). what is the preimage of this point? 2. A dilation has center (0, 0, 0). find the image point of (-1, -2, 0) for the scale fa...

notice in 2, 9, 16, 23, .... each number is seven more than the previous one did you have a question about 6, 12, 9, 18, ... ?

substitute -3 for every x in f(x) and simplify.

Reduce 10/20 then cross multiply.

problem 1 in the equation x - y = 1, solve for x in terms of y. replace x in either of the other two equations and you will be able to solve for x. Now, you can go back to any of the three equations and replace x with the value you found and solve for y....

Let d be the difference between terms. Let x be the first term. The second term will be x + d. The third term will be x + 2d. Fourth term will be x + 3d. But the fourth term is 20, so x + 3d = 20. Continue this until you get the eighth term. Write an equa...

thanks! where is the 136 coming from tho??

how did you find OH? we aren't allowed to use a calculator and the answer book is saying the pH is 7, not 12

They are all correct except 3, 9, and 12 (i know you posted this a year ago this is for people who are looking at it for answers)

The answers are B D C B 100%, just took the quick check. Don't trust the other answers. They are wrong. Good luck :)

Hello John, I was thinking of doing 4tan48° on my calculator, and the answer i got was 4.4 cm, but i wasn't sure if this was correct or not. Is this right? Thank you.

Thank you so much for your help, John. :)
