Which statement is the most appropriate conclusion for David to write? Increasing temperature had an effect on fermentation rate. The yeast in lukewarm water had a faster rate of fermentation than the yeast in room temperature water. The results do not support the hypothesis because the yeast in lukewarm water had a faster fermentation rate than the yeast in room temperature water.

Answer the statement thts mors

Explanation:

c

Explanation: I just took it

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
