yes
Explanation:
this is because the formula equation shows the details on how they solved the equation
Answer:
See the answer below
Explanation:
A neutralization reaction is a reaction that involves acid and base with the production of salt and water as the end products. An example is as below:
HCl + NaOH --> NaCl + H2O
The salt produced here is NaCl. In solution, NaCl will ionize as:
Hence, the salt's positive ion (Na+) was contributed by the base (NaOH) while its negative ion (Cl-) was contributed by the acid (HCl).
In a neutralization reaction involving Ba(OH)2 and HNO3, the salt's positive ion comes from the base and the negative ion comes from the acid. In the molecular and net ionic equations, spectator ions, which are unaltered in the process, are included and excluded respectively.
In a neutralization reaction, an acid and a base react to produce water and a salt. Taking the provided reaction of Ba(OH)2 (aq) + 2HNO3(aq) → Ba(NO3)2(aq) + 2H₂O(1), the salt's positive ion (Ba²+), also known as the cation, comes from the the base, Ba(OH)2. The salt's negative ion (NO3-), also known as the anion, comes from the acid, HNO3. This reaction also represents a molecular equation where all reactants and products are represented as neutral substances. A net ionic equation would exclude the spectator ions, ions whose presence is required to maintain charge neutrality but are chemically and physically unaltered by the process.

Explanation:
because it is the 92nd element on the table it has 92 protons
There are approximately 1.0545 x 10^24 atoms in 1.75 mole of CHCl3.
To calculate the number of atoms in 1.75 mole of CHCl3, we need to use Avogadro's number, which is 6.02 x 10^23 atoms per mole. The atomic mass of CHCl3 can be calculated by adding up the atomic masses of its constituent atoms. Carbon has an atomic mass of 12.01 g/mol, hydrogen has 1.01 g/mol, chlorine has 35.45 g/mol, and there are 3 chlorine atoms in CHCl3. So, the total atomic mass of CHCl3 is 12.01 + (1.01 x 3) + 35.45 = 119.48 g/mol. Therefore, 1.75 mole of CHCl3 contains (1.75 mol) x (6.02 x 10^23 atoms/mol) = 1.0545 x 10^24 atoms.

To find the number of atoms in 1.75 moles of CHCl3, multiply 1.75 moles by Avogadro's number, then by the number of atoms per CHCl3 molecule to get approximately 5.26925 × 10^24 atoms.
To calculate the number of atoms in 1.75 moles of CHCl3, we'll follow a few simple steps. First, remember that 1 mole of any substance contains Avogadro's number of particles, which is 6.022 × 10^23 particles/mole. The formula CHCl3 consists of 1 atom of carbon, 1 atom of hydrogen, and 3 atoms of chlorine for a total of 5 atoms per molecule.
So, if we have 1.75 moles of CHCl3, we can multiply this by Avogadro's number to find the number of molecules:
1.75 moles × 6.022 × 102^3 molecules/mole = 1.05385 × 10^24 molecules of CHCl3
Then, we multiply the total number of molecules by the number of atoms per molecule:
1.05385 × 10^24 molecules × 5 atoms/molecule =
5.26925 × 10^24 atoms
Therefore, there are approximately 5.26925 × 10^24 atoms in 1.75 moles of CHCl3.
