What volume of carbon dioxide is produced when 0.489 mol of calcium carbonate reacts completely according to the following react
Vilka [71]

Answer:

11.0L of carbon dioxide is produced

Explanation:

Balanced equation: CaCO_{3}(s)\rightarrow CaO(s)+CO_{2}(g)

According to balanced equation, 1 mol of CaCO_{3} produces 1 mol of CO_{2}

So, 0.489 mol of CaCO_{3} produces 0.489 mol of CO_{2}

Let's assume CO_{2} behaves ideally.

So, P_{CO_{2}}V_{CO_{2}}=n_{CO_{2}}RT

where P is pressure, V is volume , n is number of moles, R is gas constant and T is temperature in kelvin

Plug-in all the values in the above equation-

(1atm)\times V_{CO_{2}}=(0.489mol)\times (0.0821L.atm.mol^{-1}.K^{-1})\times (273K)

or, V_{CO_{2}}=11.0L

So, 11.0L of carbon dioxide is produced

Interpretacao gerais das praticas <br>sobre densidade de amostra solido e liquido<br>​
Savatey [412]

Answer:

O sólido tem densidade mais alta em comparação ao líquido.

Explicação:

A densidade da amostra sólida é maior do que a densidade do líquido porque há pouco espaço entre as partículas do sólido. A densidade tem relação inversa com o volume de uma substância, se uma substância ocupa mais espaço então sua densidade é menor, enquanto se a substância ocupa menos espaço então tem maior densidade. As substâncias sólidas ocupam menos espaço em comparação com as substâncias líquidas, então podemos dizer que a densidade do sólido é maior do que as substâncias líquidas.
