What can be inferred after performing the experiments in the Atomic Theory lab?
What molecular formula can you deduce from a mass spectrometry of 156 m/z. And how do you get that formula? Steps on how to get the formula is much appreciated! Thanks!
Which is true about a 99% confidence interval for a population proportion based on a given sample? I. We are 99% confident that the population proportion is in our interval. II. There is a 99% chance that our interval contains the sample proportion. III. The interval is wider ...
Thanks so much #yolo
How did you do it? :)
How do I convert this decimal into a fraction? 3.083 (The last 3 is repeating by itself)
Thanks, but for the first one, I thought it'd be no reaction since they are both metals. Is it possible for Ca and Al to react with each other?
What kind of reaction is this (redox, precipitation, acid-base, or complex ion formation reaction)? 1. 3 Ca(s) + 2 Al^3+(aq) -> 3 Ca^2+(aq) + 2 Al(s) 2. LiHCO3(s) + heat -> Li2CO3(s) + CO2(g) + H2O(g) Complete the reaction: Ni(s) + 2 Na^+(aq) -> ?
all are struck with 8d you need 3a?
