Ans: carpool

Exhaust from vehicles is a major source of air pollution. Majority of the vehicles use oil as the fuel source. Oil essentially a hydrocarbon which undergoes combustion in the presence of oxygen to produce carbon dioxide and water. However, insufficient oxygen inhibits complete combustion and produces toxic CO (carbon monoxide). In addition, oxides of nitrogen (NOx) are also released from vehicle emissions.

Burning of wood releases large amounts of polycyclic aromatic hydrocarbons (PAHs) which are highly toxic.

Thus, the best way to reduce air pollution is to carpool, which would reduce the number of vehicles on road.

I would say carpool why because you don't know what the hybrid car runs on

The reaction:L-glutarmate + pyruvate → α-ketoglutarate + L-alanine is catalyzed by the enzyme L-glutamate-pyruvate aminotransfer
sveticcg [70]

Answer:

Reaction Quotient, Kq = {[a-ketoglutarate]x[L-alanine]}/{[L-glutamate]x[pyruvate]}

or, Kq = {(1.6x10-2)x(6.25x10∧-3)}/{(3x10∧-5)x(3.3x10-4)} = 1.01 x 10∧4

Since Kq > Keqb ; therefore the reaction will proceed in the backward direction, in order words the reaction will not occur in forward direction. i.e formation of reactants will be favored.

Explain the properties of the substance around us depend on the atoms and molecules that compose them
Fynjy0 [20]
Form determines function is the explanation in this statement.The example is Na+ is table salt but Na is highly unstable. Understanding its form and function is very important in making an experiment. So we need to know and understand the relationship between form and function for appreciating.

What is the ph of with a 4.6 x 10-6 M hydroxide ion concentration?
nlexa [21]
<h3>Answer:</h3>

pH = 8.66

<h3>Explanation:</h3>
  • The pH refers to the acidity or alkalinity of a solution.
  • It is calculated by getting the negative logarithm of Hydrogen ions concentration.
  • pH=-log[H⁺]

In this case;

we are given [OH⁻] as 4.6 x 10^-6 M

We are required to calculate the pH

We need to know that;

pH + pOH = 14

pOH = -log[OH⁻]

To get the pH we can calculate the pOH first,

pOH = -log[4.6 x 10^-6 M]

        = 5.34

but, pH + pOH = 14

Therefore, pH = 14 - pOH

                        = 14 - 5.34

                        = 8.66

Therefore, the pH of the solution is 8.66
