Fluorine since it is a halogen (non-metal), then it would need to bond with a metal in order to form an ionic bond.

Fluorine would therefore need an element from any of the metal groups to bond with in order to form an ionic compound e.g. Group One (Sodium or Lithium) or Group Two (Magnesium or Calcium) or Group Three (Aluminum) or a Transitional metal (Copper or Vanadium).

How do I find the answer for question 3 and 4?

Q3) 1.5 mL from the 1.00 M HCl stock solution

Q4) 0.15 mL from the 1.00 × 10⁻¹ M NaOH stock solution

Explanation:

Q3) Determine the amount of 1.00 M HCl stock solution needed to form 100 mL of 1.50 × 10⁻² M HCl solution.

Q4) Determine the amount of 1.00 × 10⁻¹ M stock NaOH solution needed to form 100 mL of 1.50 × 10⁻² M NaOH solution.

To solve both of the questions we use the following formula:

initial concentration × initial volume = final concentration × final volume

For Q3 we have:

initial concentration = 1.00 M HCl

initial volume = ?

final concentration = 1.50 × 10⁻² M HCl

final volume = 100 mL

1.00 × initial volume = 1.50 × 10⁻² × 100

initial volume = ( 1.50 × 10⁻² × 100) / 1.00

initial volume = 1.5 mL from the 1.00 M HCl stock solution

For Q4 we have:

initial concentration = 1.00 × 10⁻¹ M NaOH

initial volume = ?

final concentration = 1.50 × 10⁻² M NaOH

final volume = 100 mL

1.00 × 10⁻¹ × initial volume = 1.50 × 10⁻² × 100

initial volume = ( 1.50 × 10⁻² × 100) / 1.00 × 10⁻¹

initial volume = 0.15 mL from the 1.00 × 10⁻¹ M NaOH stock solution

lord [1]

Answer:

Mendeléyev designed his table around the same time as a German chemist named Julius Lothar Meyer, who published it a year later. However, finally Mendeléyev's order was imposed. Do you know what his great success was? Help plis.

Mendeleev predicted the existence and properties of unknown elements that he called eka-aluminum, eka-boron, and eka-silicon, his table is based on atomic weight.

Explanation:

Gallium, scandium, and germanium were later discovered to coincide with his predictions. In addition to the fact that Mendeleev's table was published before Meyers, his work was more extensive, predicting the existence of other elements not known at the time.

A 56 g sample of peanut oil has a volume of 60.9 cm³. Calculate the density of the peanut oil

aleksandr82 [10.1K]

Density = mass / volume. So you'd write it out as D = 56g / 60.9cm^3, giving you 0.9195 g/cm^3.
