10 In a bond between an atom of carbon and an atom of fluorine, the fluorine atom has a

1 answer:

4 0

The best answer is (2) stronger attraction for electrons, for the fluorine atom has a higher electronegativity than the carbon one, if not highest of all nonmetals.
Hope this helps~

28. If the total pressure of a mixture of four gases (neon, carbon dioxide, oxygen and hydrogen) is 1245 mm

Bingel [31]

Answer:

D) 373 mm Hg.

Explanation:

We can solve this problem by keeping in mind Dalton's law of partial pressures, which states that the total pressure of a mixture of gases is equal to the sum of each gas' partial pressures. In other words, for this case:

Total Pressure = Ne Pressure + CO₂ Pressure + O₂ Pressure + H₂ Pressure

1245 mm Hg = Ne Pressure + 145 mm Hg + 228 mm Hg + 499 mm Hg

Ne Pressure = 373 mm Hg

The answer is option D) 373 mm Hg.

Describe an element and a compound. Compare and contrast their similarities and differences. Identify how elements are related t

Alenkasestr [34]

Answer:

» Similarities :

☑ They both react by chemical means, to produce either an element or compound as the end product of the chemical reaction.

• Take an example of Magnesium reacting with cold water:

${ \rm{Mg_{(s)} + 2H _{2} O _{(l)} → Mg(OH)_{2(aq)} + H_{2(g)}}}$

• If it reacts with steam:

${ \rm{Mg _{(s)} + H _{2} O_{(l)} → MgO_{(s)} + H_{2(g)}}}$

• [ Element: Magnesium and Compound: Water ]

They are both classified under atomic substances cause they are made up of microscopic molecules known as atoms.

☑ They are both formed up by microscopic substances known as atoms.

» Differences :

☑ Compounds generally have higher molecular masses than elements.

☑ Compounds are formed through bonding by elements while elements can naturally exist or formed by extraction, purification and concentration
