<span>The type of map that shows the type and age of
rocks in an area is called a Geologic Map. A geologic map is a special-purpose
map that represents the distribution of diverse types of rocks, as well as
locations of different geologic structures such as faults and folds. This map
is the main source of information for various aspects of land-use planning,
especially in the placement of transportation systems and buildings. Although
they are typically depicted as two-dimensional, they can also be illustrated in
its third or fourth dimension depending on the type of information needed to be
taken. </span>
<span>The reason it will be 7 for some titrations is that when you titrates a strong acid with a strong base for example HCl and NaOH the salt formed is conjugate base of strong acid and will be a very weak base
That means that it cannot produce any OH^-1 and all the H+ has been converted to water.The only source of H+ or OH is water with a Ka of 10^-14 so the pH = -log [H+]=-log 10^-7 = 7
second reason is
When you titrates a weak acid with strong base at equivalence point
only a water solution of the conjugate base exists
CH3COOH + NaOH ----- Na+ CH3COO^-1 + H2O
Since the conjugate base is the conjugate base of a weak acid it will hydrolyze in water like so
for instance Na+ CH3COO^-1 + HCl---- CH3COOH + NaCl the equivalence point will be way BELOW 7 and in the case of above will be less than 5. So pH of 7 at equivalence point is only reached in strong acid strong base titrations.

Answer:
yes they are same thing by E=MC^2 EINSTEIN'S EQUATION
I think the right answer for this question is option A. The energy absorbed so the mass will be increased.
Answer:
c.)the reactants have the same mass as the products
Explanation:
According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
hope it helps!
