Answer:
No, the nuclear charge of an atom and the nuclear charge of an ion are equal
Explanation:
The nuclear charge of an atom is the sum of the charges in the nucleus of the atom and since the positively charged protons are the only charged particle in the nucleus of an atom, we have that the number of protons is equivalent to the nuclear charge of an atom
However, since the charge of an ion is gained only by the loss or gain of electrons in its valence shell, we have that the nuclear charge of the nucleus remains unchanged and equal to the nuclear charge of the atom.
Answer:
1. 25 moles water.
2. 41.2 grams of sodium hydroxide.
3. 0.25 grams of sugar.
4. 340.6 grams of ammonia.
5. 4.5x10²³ molecules of sulfur dioxide.
Explanation:
Hello!
In this case, since the mole-mass-particles relationships are studied by considering the Avogadro's number for the formula units and the molar mass for the mass of one mole of substance, we proceed as shown below:
1. Here, we use the Avogadro's number to obtain the moles in the given molecules of water:
2. Here, since the molar mass of NaOH is 40.00 g/mol, we obtain:
3. Here, since the molar mass of C6H12O6 is 180.15 g/mol:
4. Here, since the molar mass of ammonia is 17.03 g/mol:
5. Here, since the molar mass of SO2 is 64.06 g/mol:
