Answer:
b. 54.9%
Explanation:
An emerald gemstone has the formula Be₃Al₂Si₁₆O₁₈. We can find the mass of each element in 1 mole of Be₃Al₂Si₁₆O₁₈ by multiplying the molar mass of the element by its atomicity.
Be: 3 × 9.01 g = 27.03 g
Al: 2 × 26.98 g = 53.96 g
Si: 16 × 28.09 g = 449.4 g
O: 18 × 16.00 g = 288.0 g
Total mass = 818.4 g
The mass percentage of silicon is:
(449.4 g / 818.4 g) × 100% = 54.91%
It would be conduction because it is the transfer between two objects.
Answer:
storage solution , deionized water, stabilizes
Explanation:
A pH meter is a scientific device or instrument that is used to measure the pH of a given aqueous solution thereby determining the nature of the solution whether it is acidic or basic or neutral.
While using the pH meter or taking the measurement using the pH meter --
- it should be kept in a storage solution for effective working.
- Before using the device, it is rinsed with a deionized water and pat dry.
- Record the measurements when the pH meter stabilizes.
This would be difficult to specify for you because you did not provide the genotype of the other parent. However, there are limitations to the possible combinations, so I will do each to help you out.
<u>1st possibility:</u>
<u>B B</u>
B BB BB
b Bb Bb
Brown eyes: 4 out of 4 or 100%
Blue eyes: 0 out of 4 or 0%.
<u>2nd possibility:</u>
<u>B b</u>
B BB Bb
b Bb bb
Brown eyes: 3 out of 4 or 75%
Blue eyes: 1 out of 4 or 25%.
<u>3rd possibility:</u>
<u>b b</u>
B Bb Bb
b bb bb
Brown eyes: 2 out of 4 or 50%
Blue eyes: 2 out of 4 or 50%.
<u>As long as there is a capital letter in the genotype, the dominant trait will come out. So if the combination is </u><u>Bb or BB</u><u>, then </u><u>BROWN </u><u>in this case will come out. The only time </u><u>BLUE eyes </u><u>will come out is if has two recessives in its genotype or </u><u>bb.</u>
