There is no problem with the model formed by atoms as solid spheres for macroscopic measurements because the atoms are extremely small.
<h3>What is Dalton's atomic model?</h3>
This was formulated in 1808 and states that atoms with spheres cannot be divided. It also states that solids are formed by contact between the spheres and chemical compounds from joining of atoms of two or more elements.
The size of the atoms in the form of sphere is very small as it is known that it is of the order of 10⁻⁹ m, therefore, having a macroscopic crystal more than 10⁻⁶ m in length which is why the model of the atom as solid spheres for macroscopic measurements has no problem.

Answer:
International is the answer duh
<em>Inflammation</em> can have causes that aren't due to underlying disease. Examples include injuries such as sprains and strains, overuse, or insect bites.
<h3>Answer:</h3>
When a disulfide linkage is formed, the compound containing this new linkage has been <u>oxidized</u>.
<h3>Explanation:</h3>
Oxidation reaction is defined as,
i) Addition of Oxygen Atoms:
When oxygen atom is added to any compound, then the compound is said to be oxidized and the reaction is known as oxidation reaction.
Example:
Oxidation of Alcohols into carboxylic acids:
R---CH₂--OH → R---COOH
ii) Removal of Hydrogen Atoms:
When hydrogen atom(s) are removed from any compound, then the compound is said to be oxidized and the reaction is also called as oxidation reaction.
Example:
Formation of disulfide bond fro thiols:
R--S-H + R--S-H → R---S--S---R
Disulfide bond is quite popular in protein chemistry where it is formed in cystine from cystein amino acids.
Answer: B) The half-life of Co-57 is 10 days
D) After twenty days have elapsed, about 25% of the Co-57 remains.
E) Scientists have an 8 gram sample of Co-57. After thirty days, 1 gram remains.
