Answer:
<u>1997.84</u>
Explanation:
(22.6g)(.52J/gC)(170C)
eliminate the respective variables
and you will only have Joules left
multiply it all
u get 1997.84
Answer:
Reactants and products
Explanation:
The reaction can be writen inthis way
⇒
Here we can notice that water and carbon dioxide are combined, so they are the reactants and produce glucose and oxygen that are the products.
Answer:
Cellular Respiration
Explanation:
Plants convert glucose to energy through a thing called cellular respiration. This process is when glucose + oxygen in the precenses of sunlight = carbon dioxide, water, and ATP(energy for the cells)
Answer:
is a mutiply choice answer just to be specific
Explanation:
7.86 is the pOH of water at this temperature of 100 degrees celsius.
Option E is the right answer.
Explanation:
Data given:
Kw = 51.3 x 
pOH = ?
we know that pure water is neutral and will have pH pf 7.
The equation for relation between Kw and H+ and OH- ion is given by:
Kw = [H+] [OH-}
here the concentration of H+ ion and OH- ion is equal
so, [H+]= [OH-]
Putting the values in the equation of Kw
pKw = -log[Kw]
pKw = -log [51.3 x
]
pKw = 12.28
since H+ ion OH ion concentration is equal the pH of water is half i.e. 6.14
Now, pOH is calculated by using the equation:
14 = pOH + pH
14- 6.14 = pOH
pOH = 7.86
