Answer:
Between galaxies, retake the measurement.
Explanation:
Among both galaxies, reiterate the measurements. Instead of utilising a balloon, a scientist might create a model that shows in which everything really is and how cosmos is expanding rather than expanding. By inflating up the atmosphere to 1/2, 3/4, and full size, continue the operation.
Answer:
a. Ethanol.
b. 4.21 mL H2O.
c. 87.8%
Explanation:
Hello,
- For the limiting reactant, the available amount of ethanol is less than the ideal amount of ethanol that would react with the given amount of oxygen, that's why it is the limiting one.
- You will find the calculations in the attached picture; take into account that the molecular mass of water is 18 g/mol and ethanol 46 g/mol.
- The percent yield is allowed to be computed in terms of volume as well, because the relationships are conserved.
Best regards!
Answer:
The new pressure is 2, 74 atm
Explanation:
We apply Boyle Mariotte's law, where for a given mass of gas at constant temperature, the pressure and volume vary inversely proportionally: P1xV1 = P2xV2 P2=( P1 x V1)/V2 1 L-----1000L--->( 140ml/1000ml)x1L=0,140 L
(50ml/1000ml)x 1L =0,050L
P2= (0,980 atm x 0,140 L)/0,050L= 2, 744 atm
Answer:
Interphase refers to all stages of the cell cycle other than mitosis. During interphase, cellular organelles double in number, the DNA replicates, and protein synthesis occurs. The chromosomes are not visible and the DNA appears as uncoiled chromatin.
