Period 4, group 5- Vanadium
Period 5, group 7- Technetium
Period 7, group 5- Dubnium
Period 5, group 4- Zirconium
Explanation:
1. Calculate the molar masses of each compound:
2. Both masses are referred to one mole of the substances. We can do a ratio between them and the 3 g of 
:
Answer:
9.47 mL
Explanation:
The reaction that takes place is:
- 2KOH + H₂SO₄ → K₂SO₄ + 2H₂O
First we <u>calculate how many KOH moles reacted</u>, using <em>the given concentration and volume of KOH solution</em>:
- 0.061 mol/L = 0.061 mmol/mL
- 0.061 mmol/mL * 26.7 mL = 1.6287 mmol KOH
Then we <u>convert KOH moles into H₂SO₄ moles</u>, using the <em>stoichiometric coefficients</em>:
- 1.6287 mmol KOH *
= 0.8144 mmol H₂SO₄
Finally we <u>calculate the required volume of the H₂SO₄ solution</u>, using<em> the number of moles and given concentration</em>:
- 0.8144 mmol ÷ 0.086 mmol/mL = 9.47 mL
The valence orbitals of a central atom surrounded by three regions of electron density consist of a set of three sp2 hybrid orbitals and one unhybridized p orbital.
<h3> Is Nitrosyl fluoride polar or non polar?</h3>
The affinity for electrons between the two atoms will keep them together, resulting in the sharing of electron density. In the case of Nitryl fluoride, The N-F bond is polar, acting as a dipole with a partial positive charge on the nitrogen atom and a partial negative charge on the fluorine atom, respectively.
<h3>Is Nitrosyl fluoride a gas?</h3>
Nitryl fluoride, NO2F, is a colourless gas and strong oxidizing agent, which is used as a fluorinating agent and has been proposed as an oxidiser in rocket propellants (though never flown).
