Answer:
The final state of the substance is a gas.
The sample is initially a liquid. One or more phase changes will occur.
Explanation:
Let's consider the phase diagram for Argon (not to scale).
<em>A sample of argon is initially at a pressure of 49.6 atm and a temperature of 101.4 K. The pressure on the sample is reduced to 0.680 atm at a constant temperature of 101.4 K. Which of the following are true? Choose all that apply </em>
<em>The final state of the substance is a gas.</em> TRUE. At 0.680 atm and 101.4 K, the substance is a gas.
<em>The gas initially present will solidify.</em> FALSE. Initially, Ar is present as a liquid.
<em>The final state of the substance is a solid.</em> FALSE.
<em>The sample is initially a liquid. One or more phase changes will occur.</em> TRUE. The sample is initially liquid and only one phase change will occur.
Answer:
Explanation:
Depending on the elements that are being combined, a chemical reaction could occur and cause a change of color to take place if the elements reacts to the other one.
The two senses which is require in the chemical compounds be dissolved in solution before they can act as stimulants for these senses are smell and odour.
Stimulant for smell include molecules which are dissolved in the air gas easily, can be easily detected by the odour recepters which are located on the nostrils upon binding. The smell neurons transfer this information to the smell bulb which are located in the forebrain all the olfactory process occur.
The sensation of taste occur when our food is dissolved in the saliva secreted by the salivary gland located below the tongue. This food dissolved in saliva binds with the recepters of the tongue which are located on the taste buds of papillae.
Thus, we concluded that the two senses which is require in the chemical compounds be dissolved in solution before they can act as stimulants for these senses are smell and odour.
