The answer for the first question is A. Single covalent bond.
The answer for the second question is C. Carbon dioxide.
Based on the Zeroth Law of Thermodynamics, two systems are at equilibrium when there is no heat flow, q, between the systems.
Answer:
E) This is not an Oxidation/ Reduction type of reaction
Explanation:
Oxidation involves the loss of electrons while reduction involves the addition of electrons. None of the elements change their oxidation number in the reaction, so this is not an oxidation/reduction type of reaction.
<span>There are three process by which the heats are transferred.They are conduction,convection & radiation. The concept of thermos flax designed to avoid all these process,that is why we are able to keep at required temp without loss are gain of temp. The convection is a method by which the heat is transfer through third media.Please look in to my site for earth section.The heat at mandrill is transferred to lithosphere and to crest by the medium called magma. This is carrying the heat from inner layer to outer core of the earth.How the egg immersed in hot water is boiled is the same process.</span><span />
