Mass of Mercury(Hg) : 55.8 g
<h3>Further explanation</h3>
Given
Reaction
2HgO ⇒ O₂ + 2Hg
Required
Mass of Mercury
Solution
Conservation of mass applies to a closed system, where the masses before and after the reaction are the same
So mass of reactants = mass of products
Mass of reactants = mass HgO = 60 g
Mass of products = mass O₂ + mass Hg
60 g = 4.2 g + mass Hg
mass Hg = 60 - 4.2
mass Hg = 55.8 g
Answer:
Explanation:
Adding any solute to water will increase the boiling temperature, as it reduces the vapour pressure, meaning a slightly higher temperature is required in order for the vapour pressure to become equal to atmospheric pressure and boil the water. Essentially, adding any non-volatile solute (such as salt, baking soda or sugar) to a liquid causes a decrease in the liquid's vapour pressure.
Answer:
Density = 8.75ml
Explanation:
Density = Mass / Volume
In this problem ...
Mass = 28 grams
Volume = 31.4ml - 28.2ml = 32ml (water displacement also)
∴Density = mass /volume = 28g/32ml = 8.75g/ml
Answer:
The light bends
Explanation:
When it passes through two different densities it changes directions, causing a bend

The pyruvate dehydrogenase complex (PDC) is a mitochondrial multienzyme complex composed of three different enzymes
<h3>What reaction is catalyzed by enzyme 2 of the pyruvate dehydrogenase complex ?</h3>
the pyruvate dehydrogenase complex is the bridge between glycolysis and the citric acid cycle
- Five coenzymes are used in the pyruvate dehydrogenase complex reactions: thiamine pyrophosphate or TPP, flavin adenine dinucleotide or FAD, coenzyme A or CoA, nicotinamide adenine dinucleotide or NAD, and lipoic acid.
- during the reactions catalyzed by the pyruvate dehydrogenase complex, it is first reduced to dihydrolipoamide, a dithiol or the reduced form of the prosthetic group, and then, reoxidized to the cyclic form.
