Answer:
anthropogenic sources like landfills, agricultural activities,coal mining and combustion and some sources are natural ones
Answer:
a. True
Explanation:
The data curve for OCI-/H3O appears to be similar to C2H3O2-/H3O because protons have not dissociated with conjugate base. This conjugate base is strong and hold proton in solution while acids try to dissociate it.
The base conjugate acid pair when strong acid is added to methylamine CH3NH2 is
base CH3NH2; conjugate acid: CH3NH3 +
Explanation
When a base CH3CH2 accept proton it form its conjugate acid which known as methyl ammonium ion. Therefore conjugate acid of CH3CH2 is CH3NH3+ ion
For example when CH3CH2 react with HCl
CH3CH2 +HCl → CH3CH3+ + Cl-
For each ionic compound formula, identify the main group to group 17 (VIIA).
Group17 (VIIA) is the primary group to which X belongs in each ionic combination with the formula CaX2. X is undoubtedly an electron acceptor. It is capable of taking an electron. We determine that X must be in the oxidation state -1 by looking at the chemical formula. The neutral ionic compound's total number of oxidation states is zero. Since calcium has an oxidation state of +2, we must identify the element that contains an anion with an oxidation state of -1. The halogens have a strong propensity to pick up an electron and create an anion. X belongs to group17 (VIIA) as a result.
