@prof_vicki_w#SolutionSquad#ChemsGr8 The subscripts are the amount of each element present in a substance and the coefficient tells you how many molecules there are of that substance.
@prof_vicki_w An isotope is an element with similar chemical make-up and the same atomic number, but different atomic weights. Different number of neurons. Same number of protons and electrons. #ChemsGr8#SolutionSquad
@prof_vicki_w Accuracy refers to the closeness of the actual measurement to the standard measurement, on the other hand, precision means the closeness of various measurements with each other. #ChemsGr8
@prof_vicki_w Chemistry in the kitchen! Caramelizing onions, heating things up and cooling things down, the rise of bread, the smell of bacon cooking on the griddle. It's all chemistry, and I love it!
The President of the United States this morning telling brown-skinned Americans to “go back to where they came from” should piss off ALL Americans.
But it won’t. And that’s a shame. A damn shame.
When @realDonaldTrump tells four American Congresswomen to go back to their countries, he reaffirms his plan to “Make America Great Again” has always been about making America white again.
Our diversity is our strength and our unity is our power.
