For #1 it is bb for brown since it is recessive and Bb for black since it is dominant. For #2, 3,4,and 5: when you do the Punnett square thing, it will be : Bb, Bb, bb, and bb. bb is for the light colored mice/rats and Bb for the dark mice. #6 is Bb, #7 none of the genotypes were purebred, #8 if both parents were brown then they would only have brown offspring, #9 both of the offspring are heterozygous black, #10 both of the offspring are homozygous brown
Avogadro's number is equal to 6.02 E 23
Thie means we have 6.02 E 23 marshmallows.
Assuming each marshmallow to be a small cylinder we can calculate the area of its base
Area circumference = pi*r² = pi * (0.635/2)² = 0.317 cm²
So, 6.02 E 23 marshmallows * 0.317 cm² cover a total area of
Area covered = 1.908 E 23 cm² = 1.908 E 13 km²
<span>The land area of california is 1.560 E 5 mi</span>² = 4.04 E 5 km²
If we divide the Areas >>>>
1.908 E 13 km² / 4.04 E 5 km² = 47. 227 E 6 (This is the number of times the area of California could be filled with those marshmallows)
Now for the height, we multiply this number times the height of each marshmallow
47. 227 E 6 * 2.54 cm = 119.96 E 6 cm = 1199.6 km above the surface
Moment is mass times speed
INITIAL moment before collision was 20 000 times 25 = 500 000
Answer:
Neutralization reaction
Explanation:
A neutralization reaction is an acid-base reaction that will yield a neutral solution because the end point of the reaction is reached in the process.
Neutralization reaction reactions occurs between an acid and a base where by the hydrogen and hydroxyl ions are combined to give water and the remaining ions produced the neutral salt.
When a strong acid and strong base combines, they produce a solution of pH 7 because they are ionized completely when the react.
