A 250 mL beaker is submerged in a large container of Liquid X and turned upside down, and another 250 mL beaker is submerged and
vovangra [49]

Answer:

Mx will be less than My.

Explanation:

The correct option is - Mx will be less than My.

Because, liquid X have been higher viscosity and vapor pressure than liquid B.

Vapor pressure of liquid A is greater, so the amount of liquid X will vaporized greater and H2 gas has been displaced greater from the beaker as compared to liquid Y.

The amount of H2 in liquid Y remains greater in beaker as compared to liquid X.

So, Mx will be less than My.

Which measurement, temperature or volume, limits the precision of the data obtained in the experiment? explain?
GrogVix [38]

The answer is volume that is volume limits the precision of data obtained in an experiment  .

As while pouring of the liquids, we control the volume, but it can have been off. And this could results in the wrong mole to mole ratio.Thus it limits the precision, So the answer is that volume limits the precision of data obtained in an experiment .

Electrons orbit in orbitals (s, p, d, f).
Technically, the number of orbitals extend to infinity, but the effective nuclear charge decreases as the distance increases.

Methane and oxygen react to form carbon dioxide and water. the reaction speed can be increased by:
oee [108]

Answer:

- Increasing the temperature.

- Increasing the reactants' initial concentrations.

- Using a catalyst.

Explanation:

Hello,

In this case, this is about the combustion of methane which is shown below:

CH_4+2O_2-->CO_2+2H_2O

Therefore, three ways to speed up this chemical reaction is via:

- Increasing the temperature: in this fashion, it is possible to accelerate the molecules crashing (via kinetic energy) in order to diminish the activation energy and to allow the reaction to be carried our more rapidly.

- Increasing methane's and oxygen's initial concentration: it is known that the reaction rate depends directly upon the reactants initial concentration, thus, by increasing the reactants' initial concentration, the molecules will crash closely and there will be more possibilities for them to crash and turn into the products.

- Using a catalyst: it is widely known that catalysts diminish the reaction rate, in this manned a catalyst could be used to speed the reaction up.

Best regards.
