Answer:
yes and no
Explanation:
If we don't, who knows what they'll do? Remember the stem cell research? that was research that killed an embryo. Then again, that was research, not the entire science itself. Just a limit on WHAT they do would be good.
Answer:
77%
1.98/2.57= 0.770428016 = 77%
Answer:- Mass of copper piece is 290 gram.
Solution:- We know that, mass = density * volume
density of copper is given as 8.96 gram per mL.
Volume of copper piece is the rise change in volume.
Volume of copper piece = 137 mL - 105 mL = 32 mL
Let's multiply the volume by density to calculate the mass of copper:
mass of copper =
mass of copper = 286.72 g
Volume has two significant figures, so if we round the mass to two significant figures then it becomes 290 g.
You have to solve it and color in the numbers i guess? It doesnt show all of the work
