Highest height : Potential energy = high | Kinetic energy = low
Lower height: kinetic Potential energy = low | Kinetic energy = high
*Remember it by when its higher thats when it has "high potential" :)*
<u>Answer:</u> The volume of concentrated solution required is 9.95 mL
<u>Explanation:</u>
To calculate the pH of the solution, we use the equation:
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
We are given:
pH = 0.70
Putting values in above equation, we get:
![0.70=-\log[H^+]](https://tex.z-dn.net/?f=0.70%3D-%5Clog%5BH%5E%2B%5D)
![[H^+]=10^{-0.70}=0.199M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-0.70%7D%3D0.199M)
1 mole of nitric acid produces 1 mole of hydrogen ions and 1 mole of nitrate ions.
Molarity of nitric acid = 0.199 M
To calculate the volume of the concentrated solution, we use the equation:
where,
are the molarity and volume of the concentrated nitric acid solution
are the molarity and volume of diluted nitric acid solution
We are given:
Putting values in above equation, we get:
Hence, the volume of concentrated solution required is 9.95 mL
Answer:
1.200g
Explanation:
At the top it's 0 and that scale goes by 10s
The middle scale is 1 and it goes by 1s
The bottom scale is .2 and it goes by .1s
1+.2= 1.2 the extra zeroes are just place holders
1.200g
The density of the sample is 0.96 g/mL.
Density is found by dividing the mass of an object by its volume.
D=m÷v
D=35.4 g÷36.82 mL
D=0.96 g/mL
Answer:
Haploid - 13
Triploid - 39
Tetraploid - 52
Trisomic - 27
Monosomic - 25
Explanation:
A haploid organism has half the chromosome number of a diploid version, hence 26/2 = 13
A triploid organism has 3 sets of a haploid chromosomes, hence 13 x 3 = 39
A tetraploid is double of a diploid, 26 x 2 = 52
Trisomic organisms have one extra chromosome in addition to the normal diploid. Hence 26 + 1 = 27
Monosomic organism has one less chromosome than the normal diploid. Hence 26 - 1 = 25
