Answer:
Freeze wedging is caused by the repeated freeze-thaw. Frost wedging occurs as the result of 9% expansion of water when it is converted to ice. Cracks filled with water are forced further apart when it freezes.
Answer:
the answer is scientific question
Explanation:
So back in 1665 Robert hook was able to view cells and describe them along with pictures, the reason he was able to see cells was because the microscope was invented a bit before, which allowed him to think about things differently, he was looking at a cork and saw squared objects, these objects were cells, according to him.
So while the cork was the reason he discovers cells on it in the first place,
The microscope was what allowed him to do that
So it’s (HOOKE LOOKING AT A CORK)
And it’s (THE INVENTION OF THE MICROSCOPE)
Answer:
0.9433g
Explanation:
Theoretical yield is defined as the mass produced assuming all reactant reacts producing the product.
Assuming the reaction is 1:1, we need to find the moles of E-stilbene (Reactant). If all reactant reacts, the moles of E-stilbene = Moles of product.
Using the molar mass of the product we can find the theoretical yield as follows:
<em>Moles E-stilbene:</em>
0.50g * (1mol/180.25g) = 0.00277 moles = Moles Product
<em>Mass Product = Theoretical yield:</em>
0.00277 moles * (340.058g/mol) = 0.9433g
Because they don't care and think the ozone layer is fine.
