Anybody wana do this? Lol much appreciated.
Alex73 [517]
No units are provided in the data table, though one would usually assume that 0.244 is molarity of NaOH, and buret data of 14.7 is probably the final volume of NaOH in mL. No identification is given for the 38, but maybe this is the initial buret volume in mL.

If the buret was rinsed with water, it should have been left to dry for some time, or else the added water may slightly dilute the NaOH solution placed in it.

525L

Explanation:

Given parameters:

Volume to Temperature ratio = 1.75

Temperature = 300k

Unknown:

Volume of the gas = ?

Solution:

We must carefully analyze and comprehend the detailed description of this experiment:

 It was suggest that the gas could expand or shrink without changing the pressure of the gas inside.

This implies that the pressure in the vessel is constant

This similar to the postulate of the Charles's law: The volume of a fixed mass of gas is directly proportional to the absolute temperature if the pressure is constant.

 Mathematically;

                 \frac{V1}{T1}  = \frac{V2}{T2}

V and T are the volume and temperature

 Now we can solve the given problem;

           \frac{V}{T}  = 1.75

Since temperature is given as 300K

 Input the variables:

           \frac{V}{300}  =  1.75

          V = 1.75 x 300 = 525L

How do dominant genes and recessive genes affect taste?
kherson [118]

Answer:

Explanation:

Because it is genetic, taste is thus inherited based on the allele combination, or “to taste, or not to taste”. The ability is highlighted here; the ability to taste PTC shows a dominant pattern of inheritance. A single copy of a tasting allele (T) conveys the ability to taste PTC.
