Best way: A good way to slow down the antibiotic resistance is that people can use antibiotics only when needed. This will make it so the virus does not become resistant to the antibiotics as quickly. This the most important way because new antibiotics take time to develop, and once one is used frequently enough, a new one is needed to replace it.

How consumers affect which goods and services are produced.

oksano4ka [1.4K]

Consumers affect the goods and services produced through:

- The more we buy something the more popular it is and the more of it is made

- The products that is less popular and less made are because we don't buy them

- When we buy more of something the more expensive the product or service will be

- When we buy less of something the more cheaper that product or service will be

A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is

Airida [17]

Answer:

the maximum safe operating temperature the engineer should recommend for this reaction is 616 °C

Explanation:

Given the data in the question;

First we calculate the Volume of the steel cylinder;

V = πr²h

radius r = Diameter / 2 = 27 cm / 2 = 13.5 cm

height h = 32.4 cm

so we substitute

V = π × ( 13.5 cm )² × 32.4 cm

V = π × 182.25 cm × 32.4 cm

V = 18550.79 cm³

V = 18.551 L

given that; maximum safe pressure P = 3.10 MPa = 30.5946 atm

vessel contains 0.218kg or 218 gram of carbon monoxide gas

molar mass of carbon monoxide gas is 28.010 g/mol

moles of carbon monoxide gas n = 218 gram / 28.010 g/mol = 7.7829 mol

we know that;

PV = nRT

solve for T

T = PV / nR

we know that gas constant R = 0.0820574 L•atm•mol⁻¹ K⁻¹

so we substitute

T = ( 30.5946 × 18.551 ) / ( 7.7829 × 0.082 )

T = 567.5604 / 0.6381978

T = 889.317387 K

T = ( 889.317387 - 273.15 ) °C

T = 616.167 ≈ 616 °C { 3 significant digits }

Therefore, the maximum safe operating temperature the engineer should recommend for this reaction is 616 °C

A barium atom attains a stable electron configuration when it bonds with

Dennis_Churaev [7]

Answer;

-Two chlorine atoms

Explanation;

A barium atom attains a stable electron configuration when it bonds with two chlorine atoms.

-Barium is an alkaline earth metal, in group two of the periodic table. Like other alkaline earth metal it has a valency of two which means it reacts by loosing two electrons.

-Chlorine on the other hand is a halogen (group seven element) it reacts by gaining an electron, thus two chlorine atoms will require two electrons. Therefore, Barium would attain a stable configuration by loosing two electrons to two chlorine atoms.
