tigry1 [53]

Answer:

Volume = 72.7272

Explanation:

if only pressure and volume change, then we can do some simple math to find the answer.

2 x 10 ^ 6 times 1 x 10 ^-5 = 20

pressure and volume must equal 20

20 = 0.275 x volume

20 / 0.275 = new volume

I don't remember significant digits but your volume is 72.72727272 just repeated

mrs_skeptik [129]

Answer : The correct option is, 13.7 mole

Solution : Given,

Moles of H_2 = 27.4 moles

The given balanced chemical reaction is,

2H_2+O_2\rightarrow 2H_2O

From the balanced chemical reaction, we conclude that

As, 2 moles of H_2 react with 1 moles of O_2

So, 27.4 moles of H_2 react with \frac{27.4}{2}=13.7 moles of O_2

Therefore, the number of moles of oxygen O_2 required are, 13.7 moles

Check Explanation

Verificar explicação

Explanation:

English Translation

What is the relationship and the PROPORTIONS between Joules, lime, Cal, and Kcal?

Joules is the SI unit of Energy (heat energy).

Calorie, also called lime, is the amount of heat required to raise the temperature of 1 gram of pure water by 1°C or 1 K.

1 calorie = 4.186 J

A thousand calorie is equal to 1 kcal.

Hence,

1 kcal = 1000 calories = 4186 J

In Portugese/Em português

Joules é a unidade SI de energia (energia térmica).

Caloria, também chamada de cal, é a quantidade de calor necessária para elevar a temperatura de 1 grama de água pura em 1°C ou 1 K.

1 caloria = 4,186 J

Mil calorias é igual a 1 kcal.

Portanto,

1 kcal = 1000 calorias = 4186 J

Hope this Helps!!!
