Answer:
The answer is Industrial smog.
Explanation:
Industrial smog is a secondary pollutant formed from the burning of coal or oil which releases a combination of carbon monoxide, sulfur dioxide and soot which eventually cause damage to the ozone layer and the environment and it causes acid precipitation or acid rain.
They are grouped together because they share certain physical and chemical properties. For instance, metals are dense, shiny, good conductors of heat and electricity, and they easily lose electrons in chemical reactions. In contrast, nonmetals have the opposite properties.
Answer:
96.92 K
Explanation:
Applying,
V/T = V'/T'..................... Equation 1
Where V = Initial Volume, T = Initial Temperature, V' = Final Volume, T' = Final Temperature.
Make T the subject of the equation
T = VT'/V'................. Equation 2
From the question,
Given: V = 268 mL, V' = 824 mL, T' = 25°C = (25+273) = 298 K
Substitute these values into equation 2
T = (268×298)/824
T = 96.92 K
Hence the Initial temperature of Nitrogen gas is 96.92 K
Answer:
True.
Explanation:
The boiling point of acetone is 56°C while boiling point of 2-methyl propane is -11°C. Based on these values, <em>boiling point of acetone is much greater than the boiling point of 2-methylpropane. </em>
That could be because acetone has an electronegative atom (Oxygen) doing high intermolecular forces in this molecule while 2-methylpropane is an apolar molecule.
