Answer:Strontium-90 and cesium-137 have half-lives of about 30 years (half the radioactivity will decay in 30 years). Plutonium-239 has a half-life of 24,000 years. High-level wastes are hazardous because they produce fatal radiation doses during short periods of direct exposure.

Answer:

10,000

Explanation:All toxic waste needs to be dealt with safely, not just radioactive waste. The radioactivity of nuclear waste naturally decays, and has a finite radiotoxic lifetime. Within a period of 10,000 years, the radioactivity of HLW decays to that of the originally mined ore. Its hazard then depends on how concentrated it is.

<h2>Acetic Acid</h2>

Explanation:

  • Initial alcohol that is formed from methane is methanol that can be converted to acetic acid.
  • Methanol in presence of CO_2 and hydrogen gas gets oxidized to acetic acid with the release of water.

Hence, compound A will be Acetic acid.

CH_3OH + CO_2 +H_2 → CH_3COOH + H_2O

  • The acetic acid formed can be transformed into -
  1. CH_3COOH → CH_4 + CO

        The product formed is methane and carbon monoxide.

    2. CH_3COOH → CH_2CHO + H_2O

         The product formed is formaldehyde and water.

    3. CH_3COOH + NaHCO_3 → CH_3COONa +CO_2 +H_2O

         The product formed is sodium acetate, carbon dioxide, and water.

A student observes that water in a pot on a burner becomes hotter explain how energy is conserved in the situation
Daniel [21]

  • The water in the pot becomes hotter as a result of heat transfer.

  • <em>Energy can be transferred from a region to another , but there will still the same overall amount of energy</em> ( energy conservation)

  • When a pot containing water  is  placed on the stove and  heat is applied with the burner, there is a flow of heat from the burner to the water.

  • Heat will be transferred from the burner to the pot, then there will be transferred of heat from the pot to the water, the molecules there in the water  will be energized as a result of the heat transfer until the boiling point  is  reached.

  • Energy transfer can take place in three form, this could be conduction, radiation or convention.

  • Convention which is a cyclical process is the one that occurs in fluids only so as a result of convection , the water at the bottom will be heated and the molecules start moving and it will rise till it get to the water at the top of the pot.

<em>Therefore, the water is heated as a result of heat transfer.</em>
