It's actually A.

Who cares Bob.

oh okay! I see what I did wrong. I forgot the 0 out of the 0.051. I had 0.01/0.51 and that gave me too many zeros. So then how would you calculate the pH of the solution?

**Chemistry**

0.0000196 = M?

I am sorry I got ahead of myself! It would be kind of important! We have 26.0 ml 0.01 M NaOH and we are adding it to 25.0 ml 0.01 M HCL. what is the molarity of excess NaOH in the mixture?

**Chemistry**

suppose you added 26.0 ml of 0.01 M NaOH to the solution, what is the molarity of excess NaOH in the mixture? what is the ph of this solution?

An 8.00g bullet is fired at 220m/s into a 250g wooden block that is initially at rest. The bullet remains in the block and after the collision the two slide up a 30° incline. a. Solve for the velocity of the bullet-block after the collision. (ans: 6.82m/s) b. Determine ...

First draw a picture. So draw a stick figure looking at a tree. So the figure (you) is 22 ft away from the tree, so draw a line from you to the tree and label it 22ft. Next you said that you look to the top of the tree which is 33 ft away, then draw a line from the your figure...

yes ma'am. ray is correct

I think it may be C..

**HEALTH**

i have c wrong

**health**

good! because d is wrong

**HEALTH**

i got b wrong ...

**health**

yeah i got c wrong

**health**

I think it is D, also.

**14**

c is wrong

**9**

d is wrong i missed it

**health**

no d is wrong.. i missed that answer, i think its c
