The solution of dextrose has a w/v% of 70 %. this means the mass of dextrose is 70 % of the volume of the solution.
In 100 mL of the solution - mass of dextrose is 70 g
therefore in 400 mL of the solution - mass of dextrose is - 70 /100 x 400 = 280 g
mass of dextrose is 280 g

A mixture of hept-1-yne, hept-2-yne, and hept-3-yne was hydrogenated in the presence of a platinum catalyst until hydrogen uptak
arsen [322]

Answer:

Only one seven carbon hydrocarbon was produced.

Explanation:

  • Alkynes are reduced completely in presence of Pt/H_{2} to produce alkanes.
  • Hydrogenation in presence of Pt is a simple nucleophilic addition process where H_{2} molecule adds onto an unsaturated bond.
  • Hept-1-yne, hept-2-yne and hept-3-yne are constitutionally isomeric to each other. Hence, after complete reduction, all three alkynes produced heptane as only product.
  • So, only one seven carbon hydrocarbon was produced.

Coal like graphite is composed of carbon. Unlike graphite, coal is formed by decayed, once living matter. Is it a mineral?
Simora [160]
Coal is not a mineral. It's not a mineral because minerals are inorganic. Coal is organic because it comes from decayed living matter.
