Answer:The endpoint does not correspond exactly to the equivalence point

At the endpoint, a change in a physical quantity associated with the equivalence point occurs.

At the equivalence point, the mole number of equivalents of reagent added is equal to the mole number of equivalents of analyte present.

Explanation:

The end point is always indicated by some physical property that changes such as colour. At the equivalence point, the mole number of equivalents of reagent added is equal to the mole number of equivalents of analyte present. The equivalence point cannot be physically observed but can be deduced after a titration curve is plotted.

Hatshy [7]
<span>One reason confidentiality would be important at a time of a medical emergency is if the patient didn't want people to know about the emergency so that they wouldn't worry. Another reason is for instance if that medical emergency was something that the patient considered embarrassing then they wouldn't want people to know.</span>

According to the kinetic theory, collisions between molecules in a gas _____.
marin [14]
<span>One of the main tenets of kinetic molecular theory is the the molecules of gas conserve their kinetic energy perfectly when they collide with each other (or the walls of the container for that matter), thus keeping them in constant motion. Since this is the definition of then elastic collision (one in which kinetic energy is maintained), then the answer is "d. are perfectly elastic".</span>

A 63.5 g sample of an unidentified metal absorbs 355 ) of heat when its temperature changes
insens350 [35]

0.208 is the specific heat capacity of the metal.

Explanation:

Given:

mass (m)  = 63.5 grams 0R 0.0635 kg

Heat absorbed (q) = 355 Joules

Δ T (change in temperature) = 4.56 degrees or 273.15+4.56 = 268.59 K

cp (specific heat capacity) = ?

the formula used for heat absorbed  and to calculate specific heat capacity of a substance will be calculated by using the equation:

q = mc Δ T

c = \frac{q}{mΔ T}

c = \frac{355}{63.5X 268.59}

 = 0.208 J/gm K

specific heat capacity of 0.208 J/gm K

The specific heat capacity is defined as  the heat required to raise the temperature of a substance which is 1 gram. The temperature is in Kelvin and energy required is in joules.
