The green section of the graph represents ice or the solid phase. This is an area where there is a high pressure but lower temperature. The yellow section represents water or the liquid phase where there is neutrality in pressure and temperature. It is also referred to as the stable phase. On the other hand, the blue section represents the gas phase. The gas phase is generally an area where both pressure and temperature are high.

The yellow line indicates sublimation. Sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

Following the things I've mentioned, at 12.00 atm and -40°C, the matter is supposed to be at its liquid phase.

You have dissolved 10 g sodium oxide in 200 ml water.calculate. the concentration of the solution

mash [69]

0.05M is the concentration of the solution.

The amount of a chemical substance in a mixture is expressed by the substance's concentration. Concentration can be expressed in numerous ways. In chemistry, the terms "solvent" and "solute" are used to denote the substance of interest and the medium in which it is dissolved, respectively

Subtract the solute's mass from the total volume of the solution. Using m as the solute's mass and V as the total volume of the solution, write out the equation C = m/V. To get the concentration of your solution, divide the mass and volume figures you discovered and plug them in.

C = m / V

C = 10 / 200

C = 0.05M.

How could you test to see if an enzyme was completely saturated during an experiment?

rodikova [14]

To test this, you'd need to see if a reaction is still taking place, If the enzyme is completely depleted, then the reaction could no longer occur.

If an equal number of moles of the weak acid HF and the strong base KOH are added to water, is the resulting solution acidic, ba

s344n2d4d5 [400]

Answer:

Being a weak acid and a strong base, where it is diluted in a neutral medium such as water, the basic medium predominates, almost alkaline pH.

Explanation:

The acidity of the solution, being weak, means that its pH is not so low, therefore it will be easier to reach the values of 7 or 7 where alkalinity or basity is indicated.

JulijaS [17]

When hydrochloric acid and zinc were combined, the salt zinc chloride and hydroge gas are being produced in the flask. The flask was said to be sealed and, therefore, no gas could escape from the flask. As the temperature decreases, the pressure inside would decrease since the gas would have lower kinetic energy and would have less force to exert on the walls of the flask. This is also evident from the equation PV = nRT. As we can see pressure and temperature are directly related which means as one decreases, the other decreases as well or as one increases, the other would increase accordingly.
