Approximately how much more energy is released in a 6.5 richter magnitude earthquake than in one with magnitude 5.5?
Elanso [62]
Answer: (C) 30 times

Richter scale is used to determine the magnitude of an earthquake from the arrival time of P and S waves. It determines the total amount of energy released during an earthquake.
If Richter magnitude scale measures 6.5 then it produces 30 times more energy than 1 Richter scale magnitude during an earthquake. The magnitude of an earthquake is plotted on a logarithmic scale from 1 to 9 and increases 10 folds by one magnitude. If 6.5 is the magnitude, it means it is 10 times more than 5.5 magnitude earthquake. Similarly the amount of energy is calculated as 30 folds. So 6.5 magnitude will have 30 folds more energy released than that with 5.5 magnitude earthquake.

When titrating 50.0 mL of 0.10 M H2SO4 with 0.10 M NaOH, how many mL of NaOH will you have added to reach the 1st equivalence po
Keith_Richards [23]

Answer:

50.0mL 0.10M NaOH

Explanation:

The chemical equation of H₂SO₄ with NaOH to reach the first equivalence point is:

H₂SO₄ + NaOH → HSO₄⁻ + Na⁺ + H₂O

<em>Where 1 mole of the H₂SO₄ reacts per mole of NaOH</em>

<em />

The initial moles of H₂SO₄ are:

50.0mL = 0.0500L × (0.10 mol / L) = 0.0050 moles of H₂SO₄

As 1 mole of the acid reacts per mole of NaOH, to reach the first equivalence point we need to add 0.0050 moles of NaOH. As molarity of NaOH is 0.10M, the volume that we need to add to reach 1st equivalence point is:

0.0050 moles NaOH ₓ (1L / 0.10 moles NaOH) = 0.050L NaOH 0.10M =

<h3>50.0mL 0.10M NaOH</h3>

Phantasy [73]

Answer:

  1. Volatile organic compounds
  2. secondary pollutants or photochemical substances
  3. Air Quality
  4. Air pollution
  5. Aerosols

Explanation:

Volatile organic compounds are the  organic chemicals that get easily vaporized in air.

The secondary chemicals or the secondary pollutants are the photochemical substances that are formed in the presence of sunlight.

The amount of gases and small particles present in the atmosphere, responsible for influencing ecosystem and the wellness of human beings is known as the Air Quality

Air pollution refers to the high concentrations of gases or small particles that are present in the atmosphere, which can cause harm to the humans and other living organisms and structures established by humans.

Aerosols are the tiny particles present in liquid or solid state, that are suspended in air.
