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:
D, to repair the damged cells is noy a reason that cells reproduce by siving in order to maintaon homeostasis.
Explanation:
The compounds that can be formed by using only the cations and anions found in the item above are as follows: (1) Ca3(CO2)2, Na3CO2, NaOH, Ca(OH)2
The last two in the given are in aqueous phase. We are then left with the first two choices. Ca3(CO2)2 is exhibits a phase that is in solid form.
Hence, the answer to the question is Ca3(CO2)2
Answer:
The formal charge on N is usually -1 for an anion, 0 for a neutral compound, and +1 in cations.
