The answer is Steam because gas has the most motion
Answer:
They are very similar because they both are very important for the sustenance of the cell. Both also help to provide energy for the cell, Chloroplasts can make its own food through photosynthesis and the mitochondria helps to break down the energy.

Answer:
The pH of the HCl solution is 3.9
Explanation:
Knowing the molar mass of HCl (36.5g/mol) it is possible to calculate the number of moles of HCl in the solution,
of HCl
HCl is a strong acid and when added to water will form H+ and Cl-, thus the moles of HCl are equal to moles of H+ in 354 mL of water
The concentration of protons in the solutions is 
.
The expression used to calculate the pH is
![pH = -Log ([H^{+}]) = -Log (1.16x10^{-4} M) = 3.9](https://tex.z-dn.net/?f=pH%20%3D%20-Log%20%28%5BH%5E%7B%2B%7D%5D%29%20%3D%20-Log%20%281.16x10%5E%7B-4%7D%20M%29%20%3D%203.9)
Hence, the pH of the HCl solution is 3.9 and Pepsi has a pH of 3.4 approximately, so they have almost the same pH.
Answer:
(x+10) (x+3)
Explanation:
1) this quadratic equation is in the form of: ax^2+bx+c
where we need to figure out what*what=c(30)
and what+what=13(b)
factors of 30: -1,-30 1,30 2,15 -2,-15 3,10 -3,-10 5,6 -5,-6
factors of 30 which equal 13: 3,10
lets substitute 3 and 10 in lace of 13x to factor by grouping:
x^2+3x+10x+30
make two sets:
set a) x^2+3x
set b) 10x+30
the GCF in set a is "x":
x(x+3)
The Gcf in set b is 10:
10(x+3)
now combine the terms outside the parantheses:
(x+10)(x+3)=0
Hope this helps!
