Answer:

Chlorine and bromine

Explanation: The chlorine and bromine acts as reactive gases and destroy the ozone  present in the stratospheric ozone.

The ozone layer is present in the stratosphere to filter the harmful rays of the sun that is harmful for the people living on earth.

A chlorine or bromine molecule can destroy thousand of the ozone molecules before it leaves the stratosphere.

So, a single bromine or chlorine atom can affect the ozone layer.

When methane, CH4, is combusted, it produces carbon dioxide, CO₂, according to the unbalanced equation: CH4 +0₂ - CO₂ + H₂O.
nevsk [136]

The balanced equation will be CH_4 + 2O_2 --- > CO_2 + 2H_2O

<h3>Stoichiometric problems</h3>

The balanced equation of the reaction would be as follows:

CH_4 + 2O_2 --- > CO_2 + 2H_2O

The mole ratio of methane to carbon dioxide is 1:1.

10 grams of methane will give 10/16 = 0.625 moles

0.625 moles of carbon dioxide would give 0.625 x 44.01 = 27.506 grams.

Thus, 10 grams of methane will produce approximately 27 grams of carbon dioxide stoichiometrically.

The reaction obeys the law of conservation of mass because the atoms of all the elements before and after the reaction are balanced.

Tju [1.3M]
High-strength bolts are used in the construction of many steelstructures. For a 1-in.-nominal-diameter bolt the required minimumbolt tension is 47.25 kips. Assuming the coefficient of staticfriction to be 0.35, determine the required couple that should beapplied to the bolt and nut. The mean diameter of the thread is0.94 in., and the lead id 0.125 in. Neglect friction between thenut and the washer, and assume the bolt to be square-threaded.
