Answer:

L = 330.0 J/g

Explanation:

The heat of fusion is the energy necessary to transform 1 gram of the solid compound in its liquid phase. Fusion requires that the systems gain heat, so it's an endothermic process.

The energy (Q) is relacionated to the mass of the compound (m) and its heat of fusion (L):

Q = mL

16650 = 50.0L

L = 16650/50

L = 333.0 J/g

Heat fusion is the amount of energy required to convert one mole of ice into water, 16650J is per 50g so if we divide 16650 by 50 we find it per gram: 16650/50 = 333J/g or 0.33KJ/g

hope that helps :)

NaBH 4 reacts with water and alcohols, with the evolution of hydrogen gas and the formation of the corresponding borate, the reaction being especially fast at low pH. Nevertheless, alcohol, often methanol or ethanol, is generally the solvent of choice for sodium borohydride reductions of ketones and aldehydes.

Methanol poses a greater risk because it is metabolized into a very toxic substance i.e. formic acid and also highly poisonous.

What is Methanol?

Methanol is a promising energy carrier because, as a liquid, it is easier to store than hydrogen and natural gas. Its energy density is, however, lower than methane, per kg.

Gelneren [198K]

Answer:

yes

Explanation:

volcanoes have done wonderful things for the earth

  • They help cool off the earth removing heat from its interior
  • volcanic emissions have produced the atmosphere and the water of the oceans
  • volcanoes make islands and add to the continent

volcanoes are necessary because:

fertile is another advantage of volcanic activity."In places like Japan,Indonesia,Philippines,Hawaii,volcanic material mixed in with the soil provides a lot of important nutrients
