Answer:

d. Temperature and number of molecules of gas

Step-by-step explanation:

Boyle's Law states, "The volume of a fixed mass of a gas is inversely proportional to the pressure if the temperature remains constant."

Let's examine the words.

"… volume…is inversely proportional to the pressure …" This means that volume and pressure are the variables.

"… fixed mass of a gas …" means that the number of molecules is constant.

"… temperature remains constant" speaks for itself.

a, c, and e are wrong, because pressure is a variable.

b is wrong, because volume is a variable.

Background research about water purification and filtration!!!

notka56 [123]

Answer: It's a modern-day engineering challenge to remove human-made contaminants from

drinking water. After a quick review of the treatment processes that municipal water

goes through before it comes from the tap you will learn about the still-present

measurable contamination of drinking water due to anthropogenic (human-made)

chemicals. Substances such as prescription medication, pesticides and hormones are

detected in the drinking water supplies of American and European metropolitan cities.

The engineering design process can be used to design solutions for a real-world

problem (contaminated water) that could affect health.

Engineering Connection

The water that comes from our faucets has passed through a complex system designed

by many different types of engineers. Civil, chemical, electrical, environmental,

geotechnical, hydraulic, structural and architectural engineers all play roles in the

design, development and implementation of municipalities' drinking water supplies and

delivery systems. Hydraulic engineers design systems that safely filter the water at a

rate needed to supply a specific region and population. Chemical engineers precisely

determine the amounts and types of chemicals added to source water for coagulation

and decontamination to make the water safe to drink and not taste bad. Even so,

modern pharmaceutical and agricultural practices persist in contaminating our water

supplies.

Semmy [17]

Answer:

1. 315.4 K

2. 1560 °C

Explanation:

To convert from celsius to Kelvin, the following formula can be used:

T(K) = T(°C) + 273

Where:

T(K) => Temperature in Kelvin

T(°C) => Temperature in degree celsius

1. Determination of the temperature in Kelvin.

Temperature (T) in °C = 42.4 °C.

Temperature (T) in K =?

T(K) = T(°C) + 273

T(K) = 42.4 °C + 273

T(K) = 315.4 K

2. Determination of the temperature in degree Celsius.

Temperature (T) in K = 1833 K

Temperature (T) in °C =?

T(K) = T(°C) + 273

1833 = T(°C) + 273

Collect like terms

T(°C) = 1833 – 273

T(°C) = 1560 °C

Benzene is an organic chemical compound with the molecular formula C6H6. In the benzene molecule, carbon atoms form a ring with

Sergeu [11.5K]

Answer:

$sp^2$

Explanation:

Hello,

The six-carbon benzene ring contains two types of bonds: C-C and C-H bonds, that are $sp^2$ -hybridized σ bonds, and the six π bonds that form the aromatic ring. The σ bonds form from one $s$ orbital and two $p$ orbitals from each carbon, which then bond the carbon to the two carbons on either side and the carbon's single hydrogen. The remaining $p$ orbital from each carbon atom sticks out above and below the plane of the ring; these $p$ orbitals overlap sideways, rather than lengthwise, to form the aromatic π bond system.

Best regards.

Calculate the concentration in mol L^-1 of ammonium ions in a solution prepared by mixing 360 mL of 0.250 mol L^-1 ammonium sulf

Mnenie [13.5K]

In order to determine the concentration of ammonium ions in the solution prepared by mixing solutions of ammonium sulfate, (NH4)2SO4, and ammonium nitrate, first calculate the amount of ammonium ions for each solution.

For ammonium sulfate sol'n: 0.360 L x 0.250 mol(NH4)2SO4/ L x 2 mol NH4+ /1 mol(NH4)2SO4 = 0.18 mol NH4+
For ammonium nitrate sol'n: 0.675 x 1.2 mol NH4NO3/L x 1 mol NH4+ /1 molNH4NO3 = 0.81 mol NH4+

Thus, the amount of NH4+ ions is (0.18 + 0.81) mol or 0.99 mol NH4+. To get the concentration, multiply this to the volume of solution which is assumed to be additive, such that:

M NH4+ in sol’n = 0.99 mol NH4+/1.035 L = 0.9565 mol NH4+/ L sol’n
