Chemistry
1 answer:
DaniilM [7]3 years ago
6 0

Answer:

Pressure is 2.32 atm

Explanation:

Pressure . Volume = moles . Constant Ideal Gases . Temperature (K)

Pressure = (moles . Constant Ideal Gases . T° K) / Volume

T°K = T°C + 273 → 61°C + 273 = 334 K

Let's replace every data:

P = (0.214 mol . 0.082 L.atm/mol.K . 334K) / 2.53L

P = 2.32 atm

What is the pH of an acidic solution?
tiny-mole [99]
The answer is A, between 0 and 7.

In a pH scale from 0 to 14, we can groups these numbers into acidic, neutral, and alkaline. 7 is the neutral pH value, therefore, 0-7 is always acidic, and 7-14 is alkaline.
The smaller the number is, the more acidic the solution will be. This applies same in alkalis, the larger the pH value is, the more alkaline the solution is.

We can measure the pH of solution with many methods, the easiest way include using a pH paper, more advanced and accurate methods includes using a pH meter.

How many g of CO2 can be produced from 256 g Fe2O3?
kotykmax [81]

Answer:

if i consider this reaction

Fe2O3+ 3CO---》2Fe+ 3CO2

so let's calculate first moles of Fe2O3 i.e. = 256/159.69= 1.6 moles

So the one moles of Fe2O3 is forming three moles of CO2

hence 1.6 moles will form 4.8 moles of CO2

one mole of CO2 is 44 g so 4.8 moles of Co2 is 44×4.8= 211.2 g

so the conclusion is 211.2 g of CO2 can be produced from 256 g Fe2O3!!

i d k it's right or wrong but i tried my best :)
