Answer: 13 grams
Explanation:
The quantity of heat energy (Q) released from a heated substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
Since,
Q = 202.8 Joules
Mass of silver = ?
C = 0.240 J/g °C.
Φ = 65°C
Then, Q = MCΦ
202.8J = M x 0.240 J/g °C x 65°C
202.8J = M x 15.6 J/g
M = (202.8J / 15.6 J/g)
M = 13 g
Thus, the mass of silver is 13 grams
Answer:
The correct answer is B) both are made up of monomers that are linked by covalent bonds
Explanation:
The polymers consist of a set of monomers by covalent bonds. There are those that are natural (DNA formed by nucleotide units, proteins by amino acids, starch by glucose) and synthetics made by human hands (polyethylene formed by ethylene monomers).
Non-living molecules.

Neutrons.
Electrons have little to no mass, therefore shouldn't be electrons.
Also there is only eight protons in this atom, while there are nine neutrons.
Use water displacement.
First, measure the amount of water in a graduated cylinder.
Second, place the object in the water.
Third, measure the amount of water in the graduated cylinder currently.
Fourth, subtract the original amount of water from the risen amount of water.
This will calculate the volume.
