Answer:
Direct coupling
Explanation:
Direct coupling is sensitive to changes that occurs in temperature. It is electrical energy transfer using physical contact through a medium that is conductive.
It is useful in the interconnection of 2 circuits. This kind of coupling method can be done by a wire, a resistor or through mettalic bonding.
Index fossils are from species that only existed for a short period of time. they are found in rocky layers, Trilobites and Graptolites are index fossils. A guide and zone fossil are used often to determine the age of the rock layer in which it is found.
Answer:
Thus, when 2.5 mol of oxygen reacted with hydrogen, 2 * 2.5 mol = 5 so its A
Answer:
Explanation:
Hello,
In this case, for the given equilibrium, we write the law of mass action:
Next, in terms of the change due to the reaction extent (ICE procedure):
Clearly, the initial concentration phosphorous pentachloride is 1 M (one mole per litre), therefore, since the equilibrium concentration is 0.2 M (same volume) we can compute :
Thus, we compute the equilibrium constant:
