Answer:
I think im good at it i have an A in the class
Explanation:
lol
What you have to do is find a periodic table and add the mass of each atom that the compound is made of.
Ca= 40.1
O= 16.0
H= 1.01
keep in mind that you have to also account for how many atoms of each there are in the molecule. for example, in Ca(OH)2, there are one Ca, two O and two H
so the molar mass of Ca(OH)2= 40.1 + (2 x 16.0) + (2 x 1.01)= 74.12 g/mol
The answer should be D, cells can only create an identical copy of the original cell.
Metal because it’s more stronger
The direction of heat flow is increased which means blocks temperature is higher and hotter than it was before
