The correct response is A. Only the Fe is unbalanced.
Answer: While conduction is the transfer of heat energy by direct contact, convection is the movement of heat by actual motion of matter; radiation is the transfer of energy with the help of electromagnetic waves. The matter is present around us, in three states, solid, liquid and gas.
Answer:A
Explanation: because i saw the sheet
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.
According to the Arrhenius concept, the strength of an acid depends upon the H⁺ ions furnished by the acid.
<h3>What is the Arrhenius theory of acids?</h3>
According to the Arrhenius theory, acids are those substance which will give H⁺ ion in an aqueous solution.
And acidity of any substance will be calculated by using the pH value which can be calculated as pH = -log[H⁺].
- Hydrolysis will not able to define the strength of the acid.
- Concentration of the acid is also not valid to define the strength of the acid because all acids will not have H⁺ ion.
- Number of moles of the base which are used for neutralization is also not used to define the strength of Arrhenius acid.
Hence H⁺ ions furnished by the acid is used to define the strength of Arrhenius acid.
