Answer:
0.9307 moles have been introduced into the bag.
Explanation:
Pressure of the gas within the bag,P = 1.00 atm
Temperature of the gas remains at room temperature,T=20.0 °C = 293.15 K
Volume of the gas in the bag = V = 22.4 L
Number of moles of gas = n
Using an ideal gas equation:
n = 0.9307 moles
0.9307 moles have been introduced into the bag.
Mitosis results in two identical daughter cells, whereas meiosis results in four cells.
Answer:
Dilute 1 ml of 2M solution to 100 ml
Explanation:
C₁V₁=C₂V₂
V₁=C₂V₂/C₁=
=100×0.02/2=1ml
Answer:Here is a short list of main properties:
They form crystals. ...
They have higher enthalpies of fusion and vaporization than molecular compounds.
They are hard.
They are brittle.
They have high melting points and also high boiling points.
They conduct electricity but only when they are dissolved in water.
Explanation:
Answer:
A
Explanation:
Since water is polar, we need for there to be a polar solute. This eliminates options B and D.
Now to choose between A and C, we can look at the compounds mentioned.
For A, NH3 is mentioned, which is a polar substance.
However, for C, H2 is mentioned, which is a nonpolar molecule, contrary to what is stated by the option.
Therefore, A is the answer.
