In the event that a chemical gets in your eye while in the lab, you would use the eyewash station. In your at-home lab, however,

which of these courses of action (according to your lab procedure)could be used in lieu of an eye wash station?A. Using Visene, contact solution, or a similar eye drop immediatelyB. Using the sprayer on your sink if you have oneC. Pouring milk in your eye(s)D. A vigorous 30-second eye rub

Answer:

Using the sprayer on your sink if you have one

Explanation:

If a chemical gets into your eye, you will need to flush the eye thoroughly with water in order to get the chemical out of the eye before it causes any kind of damage to the eye.

This could normally be done in an eye wash station. However in the absence of an eye wash station, one could use the sprayer of the sink if he/she has one. This will deliver water to completely flush the eye at lower pressure.

The density of the hydrocarbon in part (a) is 2.0 g l-1 at 50°c and 0.948atm. (i) calculate the molar mass of the hydrocarbon. (
Vedmedyk [2.9K]

1. Answer;

=56 g/mol

Explanation and solution;

PV = nRT

nRT= mass/molar mass (RT)

molar mass = (mass/V ) × (RT/P)

                   = Density × (RT/P)

Molar mass = 2.0 g/L × (0.0821 × 323 K)/0.948 atm

Molar mass = 56 g/mol


2. Answer;

Molecular mass is C4H8

Explanation;

Empirical mass × n = molar mass

Empirical mass for CH2 = 14 g/mol

Therefore;

56 g/mol = 14 g/mol × n

   n = 4

The molecular formula= 4(CH2)

    = C4H8

How does the kinetic energy of solids liquids and gases compare?
maksim [4K]
<h2> <em>QUESTION</em><em>:</em><em> </em><em>how does the kinetic energy of solids liquids and gases compare?</em></h2>

<h2> ANSWER:</h2><h3><em>Gases have the high kinetic energy because its particles are far apart from each other and have negligible fprce of attraction whereas liquids have high force of attraction as compared to gases so they have less kinetic energy then gases,and Solids have high force of attraction between its particles because of that its molecules are closely packed ,so solids do not have kinetic </em><em>energy.</em></h3><h2><em>HOPE</em><em> </em><em>IT </em><em>HELPS </em><em>YOU</em></h2>

If a sample of air in a school container was heated, would the percentage of oxygen in the air increase, decrease, or remain unc
Viktor [21]

Answer:

increase

Explanation:

Let's suppose we have a sample of air in a closed container. We heat the container and we want to predict what would happen to the pressure.

According to Gay-Lussac's law, the pressure of a gas is directly proportional to its absolute temperature.

Thus, if we increased the temperature of the air by heating it, its pressure would increase.

If a sample of air in a closed container was heated, the total pressure of the air would increase.
