I don’t know how to do this
How do this
I am old and never had to do this type work. 1962 in 8th grade. How do you do the math to get where the yard on field would be placed? I get that each yard is 46my and each 10 is 460my.. for instance cretanceous era 146-65 on chart 3.174 yard line. How do
Not possible
Thank you for the feedback but after selecting this option it came up incorrect
Thanks!
Nevermind on this question I figured it out
Thank you so much!
120 degrees.
A point on the terminal side of an angle theta is given. Find the exact value of the six trigonometric functions of theta: (2,-3)
Thank you for helping me out! I am having a tough time in this class and this was a big help
i got the first one easy enough. the reading was interesting. so that leads me to believe b is the correct answer. thank you dr. bob
i believe H2C O with the double bond is the only one with a dipole moment
oh i did. thank you for your responses!
for instance would i draw something like this? the diagonal lines are suppose to be straight lines. H-C-H / H-N-H / H
thank you. but when the question asks me to draw out the product am I drawing two structures or one?
H3C+ yes that's what the problem says
i believe it wants it drawn out in a lewis structure for the product
I got it. Both have the same answers of water, methanol, ethanol and acetone!
Thanks so much and the typo was no big deal I knew what you meant. :) you're a life saver!
Thank you for your response! Having all of these numbers confused me. So for part a I'm multiplying 7.410 mL (first equivalence point) by .1523 M. I got 1.129 mmol H3PO4. Then divided it by 10.0mL to get a concentration of 0.113 M H3PO4.
Got it. Man that felt good to actually solve a problem after all these years.
i freaking do not have a clue
okay thanks
SO HOW SHOULD I COULD DO BECAUSE ITS ALL CONFUSING TO ME
