In the reaction C + 02 - CO2, 18 g of carbon react with oxygen to produce 72 g of carbon dioxide. What mass of oxygen would be needed in the reaction? O 18 g O 54 g O 72 g 0 90 g

Answers

Mass of oxygen : 54 g

Further explanation

Conservation of mass applies to a closed system, where the masses before and after the reaction are the same

Reaction

$\tt C+O_2\rightarrow CO_2$

mass before reaction = mass after reaction

mass C + mass O₂= mass CO₂

$\tt 18~g+mass~O_2=72~g\n\nmass~O_2=72-18=\boxed{\bold{54~g}}$

In a laboratory, a student makes a solution by completely dissolving 80.0 grams of KNO3(s) in 100.0 grams of hot water. The resulting solution has a temperature of 60.°C. The room temperature in the laboratory is 22°C.Classify, in terms of saturation, the type of solution made by the student.

Answers

Answer:

Unsaturated solution.

Explanation:

At 60°C, 100.0g of water can dissolve 110g of KNO₃.

By definition, if you add 110g of KNO₃, the solution will be saturated, if you add more than 110g, the solution becomes supersaturated (That means crystals of solute will form), if you add less than 110g, the solution is unsaturated.

In the problem, you are adding 80g of KNO₃(s), that means you made a unsaturated solution.

Answer: Unsaturated

Explanation: There are three types of saturation levels that can be chosen, unsaturated, saturated, and supersaturated. If you look on Table G on the Reference Table, find the temperature in which the solution is at and go up until you reach the amount of dissolved substance (grams). If the dot is over the line then it is supersaturated, if its on the line then its saturated, and if it's below the line then is unsaturated.

What is true at STP? 1) Temperature is 295 Kelvin.
2) One mole of gas occupies a volume of one liter.
3) Pressure is 1.0 atmosphere.
4) Volume is 2.4 liters

Answers

The correct answer for the question that is being presented above is this one: "3) Pressure is 1.0 atmosphere." STP stand for standard temperature and pressure. The values of STP are 22.4 liters, 1mole, 1.00 atmospheres, and 273 kelvin. Under these conditions, all gases behave ideally or the same.

Carbon monoxide (CO) reacts with hydrogen (H2) to form methane (CH4) and water (H20).CO(g) + 3H2(g) + CH4(g)+H20(9)
The reaction is at equilibrium at 1,000 K. The equilibrium constant of the reaction is 3.90. At equilibrium, the concentrations are as
follows.
[CO] = 0.30 M
[H2] = 0.10 M
[H20] = 0.020 M

Answers

Answer: The equilibrium concentration of $CH_4$ , expressed in scientific notation is $5.9* 10^(-2)M$

Explanation:

Equilibrium constant is the ratio of the concentration of products to the concentration of reactants each term raised to its stochiometric coefficients.

The given balanced equilibrium reaction is,

$CO(g)+3H_2(g)\rightleftharpoons CH_4(g)+H_2O(g)$
