The mass of the water is 1580 g.
<h3>What is the amount of water formed?</h3>
We know that the ideal gas equation can be used to obtain the number of moles of the gas. We have been told that the pressure of the gas reduced from 7.9 x 10-3 atm to 1.2 x 10-4 atm. The change in pressure can be used obtain the number of moles.
Change in pressure = 7.9 x 10-3 - 1.2 x 10-4 = 7.78 * 10^-3 atm
Using;
PV = nRT
n = PV/RT
n = 7.78 * 10^-3 atm * 2.4 x10^5 l/0.082 * (39 + 273)
n = 85 moles
Since 1 mole of carbon dioxide produces 1 mole of water
85 moles of carbon dioxide produces 85 mole of water
Mass of water produced = 85 mole * 18 g/mol
= 1580 g

Answer:
19.3 L
Explanation:
V= n × 22.4
where V is volume and n is moles
First, to find the moles of CO2, divide 38.0 by the molecular weight of CO2 which is 44.01
n= m/ MM
n= 38/ 44.01
n= 0.86344012724
V= 0.86344012724 × 22.4
V= 19.3410588502 L
V= 19.3 L
Answer:
Light as a wave: Light can be described (modeled) as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and BOOM - you have light. ... So, Maxwell's equations do say that light is a wave.
