I dont know if this will answer correctly but
A: Polar covalent
B: Ionic (non-covalent)
C: Polar covalent
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
Fusion power is the power generated by nuclear fusion processes. In fusion reactions, two light atomic nuclei fuse together to form a heavier nucleus. In doing so, they release a comparatively large amount of energy that arises from the binding energy, creating an increase in temperature of the reactants.
Hydrophobic in simple terms is the "fear" of water.
In chemistry, Ionic salts are technically hydrophilic as they will dissolve in water.
most fats and oils or triesters won't why?
salts are made from ions and their structure contain polar bonds Na+ and Cl-
Fats and oils tend to not have these.
Fats and oils contain many carbon covalent bonds which are non-polar which tend to make the molecule non-polar as a whole, therefore, it can't dissolve in water and is said to be hydrophobic.
Hope that heps :)
NB included a diagram to help.
Answer:
Torrey's neighbour is incorrect because increase in kinetic energy is proportional to velocity. If the velocity increases so will the object's kinetic energy. Because the mass is constant, if the velocity increases, so does the kinetic energy.
