1 answer:
USPshnik [31]4 years ago
6 0

Answer:

Corresponds to a covalent compound.

Explanation:

Both Boron and Fluorine are nonmetals, forming a covalent bond, the result of which is the boron trifluoride compound (BF3). This is a highly toxic gas.

It is synthesized by the reaction between hydrogen fluoride and boron oxide:

B2O3 + 6 HF → 2 BF3 + 3 H2O

What is the general trend in electro negativity as you move from left to right across the periodic table
viva [34]

Answer:

On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you go down a group. As a result, the most electronegative elements are found on the top right of the periodic table, while the least electronegative elements are found on the bottom left.

A 5.00 gram sample of an oxide of lead PbxOy contains 4.33 g of lead. Determine simplest formula for the compund
Harrizon [31]

Answer: The empirical formula is PbO_2

Explanation:

Mass of Pb =  4.33 g

Mass of O = (5.00-4.33) g = 0.67 g

Step 1 : convert given masses into moles

Moles of Pb =\frac{\text{ given mass of Pb}}{\text{ molar mass of Pb}}= \frac{4.33g}{207g/mole}=0.021moles

Moles of O =\frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{0.67g}{16g/mole}=0.042moles

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For Pb = \frac{0.021}{0.021}=1

For O = \frac{0.042}{0.021}=2

The ratio of Pb O=  1: 2

Hence the empirical formula is PbO_2
