Answer:
1 200 000 000 000 000 000 000 000 H⁺ ions
Step-by-step explanation:
Assume that the concentration of H⁺ ions in stomach ions is <em>2.0 mol·L⁻¹.</em>
Then, we have 2.0 mol of H⁺ ions
There are 6.02 × 10²³ H⁺ ions in 1 mol.
2.0 mol = 2.0 × 6.022 × 10²³/1
= 1.2 × 10²⁴ H⁺ ions
= 1 200 000 000 000 000 000 000 000 H⁺ ions
Answer:
Therefore the theoretical density of iron is 7.877 g/cm³ .
Therefore the number of vacancy per cm³ is
Explanation:
Answer:
- Elements of the the same group have similar number of valence electrons.
- They have identical number of electrons in their outermost shell. For example ; All the alkali metals in Group 1 have 1 valence electron.
And so many more.
Due to all these similarities ,they have similar properties and they tend to react similarly with other substances.
