If the pressure on a gas at -73°C is doubled but its volume is held constant, what will its final temperature be in degrees Cels
Gre4nikov [31]

Answer:

127°C

Explanation:

This excersise can be solved, with the Charles Gay Lussac law, where the pressure of the gas is modified according to absolute T°.

We convert our value to K → -73°C + 273 = 200 K

The moles are the same, and the volume is also the same:

P₁ / T₁ = P₂ / T₂

But the pressure is doubled so: P₁ / T₁ = 2P₁ / T₂

P₁ / 200K = 2P₁ / T₂

1 /2OOK = (2P₁ / T₂) / P₁

See how's P₁ term is cancelled.

200K⁻¹ = 2/ T₂

T₂ = 2 / 200K⁻¹  → 400K

We convert the T° to C → 400 K - 273 = 127°C

How do the major and minor scale divisions relate the precision of measurements taken with a metric ruler or graduated cylinder?
Nata [24]

Answer: Major scale and minor scale both relate the precision of measurements with more true value of measurement.

Explanation:

Major scale in a measuring device is maximum unit value on the scale that can be measured.

Minor scale in a measuring device is a least unit value on the scale that can be measured.

In a metric ruler major scale is 1 cm and minor scale is 0.1 mm which means one can measure accurate value up-to one decimal point and in 10 ml of graduated cylinder major scale division is 1 ml minor scale division is 0.01.

How many moles of iron (Fe) can be obtained from 3.80 g iron (III) oxide (Fe2O3) reacting with excess carbon monoxide
topjm [15]

0.02375 moles

Explanation:

Fe2O3+CO :. Fe+CO2

We know that

56*2+16*3=160 gm of Fe2O3 can give 56 gm of Fe

So

3.8 gm can give 1.33 gm of Fe

It is equal to 1.33/56 moles of Fe which is equal to 0.02375 moles
