<span>The answer is c - physical activity and exercise typically lead to higher energy levels. The endorphins and hormones released during periods of high activity actually help to combat stress and depression linked to a depletion in serotonin, and therefore can only increase the quality of life. The other possible answers to this question are therefore all incorrect.</span>
The reaction of formation of sulfur trioxide SO₃ from sulfur dioxide SO₂ is very slow because rate of reaction is very slow at room temperature.
WHAT IS REACTION FORMATION ?
Reaction Formation is the fixation in consciousness of an idea, affect, or desire that is opposite to a feared unconscious impulse.
WHAT IS RATE OF REACTION ?
The Rate of Reaction or Reaction Rate is the speed at which reactants are converted into products. When we talk about chemical reactions, it is a given fact that rate at which they occur varies by a great deal. Some chemical reactions are nearly instantaneous, while others usually take some time to reach the final equilibrium.
Thus, the reaction of formation of sulfur trioxide SO₃ from sulfur dioxide SO₂ is very slow because rate of reaction is very slow at room temperature.

Answer:
They include: Chemical nature of the pollutant - how active and toxic it is to humans, plants and animals; Concentration - the amount of the chemical per unit volume of air, water, soil, and; Persistence or longevity - how long the pollutant remains in the environment in its harmful form.
Explanation:
Air pollutants like ozone, particulate matter, carbon monoxide, nitrogen oxide, sulfur dioxide, lead cause atmospheric pollution which regards to ozone depletion, GH effect, climate change and human health effects. If anyone say the main factors of air pollution beyond of industry, means of transportation, solid waste generation and urbanization.
Growing urbanization and industrialization grows more pollution. Due to a large number of population in the world, more pollution is generated. Specifically if we talk about air pollution, due to steady increase in number of industries, the gradient level is deteriorating day by day. There is no good if we just talk about sustainable development if we are not following it.
Answer:
Q = 96.6 j
Explanation:
Given data:
Heat required = ?
Initial temperature = 19°C
Final temperature = 33°C
Mass of disc = 3.0 g
Specific heat capacity = 2.3 J/g.°C
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 33°C - 19°C
ΔT = 14°C
Q = 3.0 g×2.3 J/g.°C × 14°C
Q = 96.6 j
Answer:
The easiest way to identify a double displacement reaction is to check to see whether or not the cations exchanged anions with each other.
Explanation:
if the states of matter are cited, is to look for aqueous reactants and the formation of one solid product (since the reaction typically generates a precipitate).
