Answer:
if the red allele is dominant 3 out of 4 offspring will have the red characteristic and 1 out of 4 will have white characteristic
Answer:
17.3 g Cr
Explanation:
To find the mass of chromium, you need to (1) convert moles Si to moles Cr (using the mole-to-mole ratio from equation coefficients) and then (2) convert moles Cr to grams Cr (using the atomic mass). It is important to arrange the conversions in a way that allows for the cancellation of units. The final answer should have 3 sig figs to match the sig figs of the given value (0.250).
3 Si + 2 Cr₂O₃ ---> 4 Cr + 3 SiO₂
^ ^
Atomic Mass (Cr): 51.996 g/mol
0.250 moles Si 4 moles Cr 51.996 g
------------------------- x -------------------- x ------------------- = 17.3 g Cr
3 moles Si 1 mole
It is absurd. Environmentalists prefer that you don’t recycle at all because most if not all of our recyclables are being recycled incorrectly.
Explanation:
yes, they are the same.
"Iron is a mineral that the body needs for growth and development. Your body uses iron to make hemoglobin, a protein in red blood cells that carries oxygen from the lungs to all parts of the body, and myoglobin, a protein that provides oxygen to muscles."
Fun fact:
At 4 grams per person, you'd need at least 2,352 completely drained donors to make a iron longsword out of blood.
