Soap is polar because it is not symmetrical in molecularly, this is because it must react with whats on your hand to fully clean it , dish soap is nonpolar/polar in order to combat grease which is also nonpolar, so nonpolar cleans nonpolar and polar cleans polar
Answer:
Let x equal the percentage abundance of one of the two isotopes. The other isotope must then have an abundance of 100 percent minus x percent, which you express in decimal form as (1 - x). For nitrogen, you can set x equal to the abundance of N14 and (1 - x) as the abundance of N15.
Explanation:
A balance is used to determine mass
So that other scientist can repeat their experiments
i hope i got i right
Answer:
3.076 L.
Explanation:
- The pressure is constant as it is the atmospheric pressure.
- According to Charles’ law; at constant pressure, the volume of a given quantity of a gas varies directly with its temperature.
∴ V₁T₂ = V₂T₁.
V₁ = 2.6 L & T₁ = -11 °C + 273 = 262 K.
V₂ = ??? L & T₂ = 37 °C + 273 = 310 K.
∴ V₂ = (V₁T₂) / T₁ = (2.6 L)(310 K) / (262 K) = 3.076 L.
