Can a metal and a nonmetal participate in a combination reaction

nikklg [1K]

Answer:

Yes

Explanation:

A reaction normally takes place between metals and non metals. The metals acts as the electron donors and the non metals acts as the electron acceptors. This exchange of electrons form bonds such as ionic or covalent.

A good example of a reaction between a metal and non metal is Sodium metal and Chlorine(non metal). They form an ionic bond and the product is Sodium chloride.

5. What is the final "Celsius" temperature if 2.40 L of gas at 30.5 C is cooled until the volume reaches 1.00 L at constant pres

slega [8]

Answer:

Final temperature of the gas = -146.63 °C

Explanation:

At constant pressure, volume and temperature of the gases are related as:

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

Where,

V1 = Initial volume = 1.00 L

V2 = Final volume = 2.40 L

T1 = Initial temperature = 30.5 °C = 30.5 + 273.15 = 303.65 K

Now, substitute the values in the above equation,

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

$\frac{2.40\;L}{303.65}=\frac{1.00\;L}{T_2}$

$T_2=\frac{1.00\times 303.65}{2.40}$

T2 = 126.52 K

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15

T( °C) = T(K) - 273.15

= 126.52 - 273.15 = -146.63 °C
