Ozone which is present in the stratospheric region of atmosphere is helpful for preventing harmful UV rays from reaching the surface of earth. Due to human activity, several compounds  (specifically chlorofluorocarbons) are released in atmosphere. Due to inherent chemical stability of these compounds, the remain stable in lower region of atmosphere and slowly diffuse into stratosphere. On reaching the stratosphere, these compounds reacts with ozone and thereby depletes the effective concentration of ozone present in atmosphere. Hence, <span>the Montreal Protocol was signed in 1987 by major countries of the world. This aim of this protocol was to protect the stratospheric ozone layer by phasing out the production and consumption of ozone-depleting substances.</span>

Sphinxa [80]

Answer:

See explaination

Explanation:

The mole balance for a constant-volume batch reactor is given such as, For a first-order isothermal reaction, the time to reach a given conversion is the same for constant-pressure and constant-volume reactors. Also, the time is the same for a reaction of any order if there is no change in the number of moles.

svet-max [94.6K]

Answer:

340 N

Explanation:

<u>Force formula</u>

The force formula is defined by Newton's second law of motion: Force exerted by an object equals mass times acceleration of that object: F = m ⨉ a. To use this formula, you need to use SI units: Newtons for force, kilograms for mass, and meters per second squared for acceleration.

<u>Equilibrium</u>

It is a state of rest or balance due to the equal action of opposing forces. equal balance between any powers, influences, etc.; equality of effect. mental or emotional balance; equanimity: The pressures of the situation caused her to lose her equilibrium.<u> </u>

When an aluminum cube of edge 0.100 m and temperature T0= 5.00°C is submerged in a bucket of water, the level of the water rises
vodka [1.7K]

Answer:

5.52cm³ of water will rise and might spill over the edge

Explanation:

Use the change in volume of a liquid with changing temperature equation which is written as

ΔV = β x V₀ x ΔT, where β is the coefficient of expansion, V₀ is the volume being submerged and ΔT is the difference in temperature

ΔV = (69 x 10⁻⁶) x (0.1 x 0.1 x 0.1) x (85 - 5)

ΔV = 5.52 x 10⁻⁶ m³

ΔV = 5.52cm³
