Generally, when going from left to right across a period on the periodic table:

1 answer:

6 0

Atomic radio increases as number of valence electrons increase. Hence the first and fourth statement are wrong. Electronegativity is highest for elements on the TOP right hand corner of the periodic table so the third statement is wrong. Hence the answer is the third statement

what’s the chemical equation for production of potassium vapor and molten sodium chloride from molten potassium chloride and mol

elena-14-01-66 [18.8K]

Answer:

$\huge\boxed{\sf KCl_{(aq)}+Na_{(aq)} \longrightarrow K_{(l)}+NaCl_{(aq)}}$

Explanation:

Chemical formulas for every compound:

Potassium vapor => $K_{(l)$

Molten soldium chloride => $NaCl_{(aq)}$

Molten Potassium chloride => $KCl_{(aq)}$

Molten Sodium Metal => $Na_{(aq)}$

The reaction will be as follows:

$KCl_{(aq)}+Na_{(aq)} \longrightarrow K_{(l)}+NaCl_{(aq)}$

This reaction is usually called displacement reaction in which an element displaces another element of a compund.

For liquids, which of the following factors affect vapor pressure? Check all that apply: volume temperature

In-s [12.5K]

I believe the correct answer from the choices listed above is the second option. For liquids, it is the temperature that affects vapor pressure. The vapor pressure of any substance increases non-linearly with temperature according to the Clausius–Clapeyron relation. Hope this helps. Have a nice day.
