What is the correct term for living the most sustainable life you can within your current circumstances?
tekilochka [14]

Answer:    Sustainable living

Explanation: It is a lifestyle by which an individual uses natural resources only as much as is necessary, which means in limited quantities, and thus reduces the general enormous exploitation of these resources. In this way, the needs of the individual are met and resources are put to use for generations to come. It also refers to personal resources as well as Earth resources in general.

It is obvious from today's point of view that if food was produced only as much as needed, it would mean not throwing away food, everyone, both those who could otherwise afford food and those who are now starving, would be fed up.

With the reduction of production not only of food but also of other necessities, that is, with production to meet the needs and not beyond, there would be less pollution and less emission of harmful hags and greenhouse effect.

Write a balanced equation for the complete combustion of solid palmitic acid. Remember that oxygen (O2(g)) is necessary for the
Alina [70]

Answer:

C₁₆H₃₂O₂ (s) + 22O₂(g) → 16CO₂(g) + 16H₂O(g)

Explanation:

In order to determine a combustion reaction we should know that:

Reactants are: X compound and O₂

Products are: CO₂ and H₂O

In this case, the X compound is the solid palmitic acid: C₁₆H₃₂O₂

The balanced equation will be:

C₁₆H₃₂O₂ (s) + 22O₂(g) → 16CO₂(g) + 16H₂O(g)

A balloon filled with 1.22 l of gas at 286 k is heated until the volume is 2.86 L while the pressure remains constant. What is t
telo118 [61]

Answer: 670K

Explanation:

Given that,

Original volume of gas V1 = 1.22 L

Original temperature T1 = 286 K

New volume V2 = 2.86 L

New temperature T2 = ?

Since volume and temperature are involved while pressure is constant, apply the formula for Charles law

V1/T1 = V2/T2

1.22 L/286 K = 2.86 L/ T2

Cross multiply

1.22 L x T2 = 286 K x 2.86 L

1.22T2 = 817.96

Divide both sides by 1.22

1.22T2/1.22 = 817.96/1.22

T2 = 670.459 K (Round to the nearest whole number as 670 K)

Thus, the temperature of the gas is 670 Kelvin
