How many moles of CO gas are in 34.6 L?

Chemistry
1 answer:
Troyanec [42]2 years ago
6 0

moles of CO gas : 1.545

<h3>Further explanation</h3>

Standard conditions for temperature and pressure are used as a reference in certain calculations or conditions

There are 2 conditions that are usually used as a reference : STP and RTP

Assuming the STP state :

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.

Then for 34.6 L of CO gas :

\tt moles=\dfrac{34.6}{22.4}=1.545

Why do sea and ocean levels recede (more coast land is exposed) when the planet goes through a major ice age?
fomenos
This happens because ice is made up of water, and when that water freezes, it never goes back to land, thus there being less water on the coastline. But when the ice starts to melt, the water will even out quickly, and the water will go to the coastline, causing the tide to rise. Mark brainliest, please.

35000 kJ/ 0.250 s <br><br> kJ is kilojoules
mario62 [17]
The unit 'kJ' or kilojoules is a unit of measurement for energy. It is equivalent to the SI units kg·m²/s². When energy is divided with time, that unit is now in terms of work, which energy per unit time. The parameter kJ/s is equivalent to kW or kilowatts.

Work = 35,000 kJ/0.250 s = <em>140,000 kW</em>

53. A firefighter of mass 80 kg slides down a vertical pole
Zielflug [23.3K]

Answer:

Answer is given below:

Explanation:

<em>Given Data:</em>

mass = 80kg

acceleration = 4 ms

force = 800N

<em>Find out:</em>

friction = ?

<em>Formula</em><em>:</em>

F-friction = weight - f-net

<em>Solution:</em>

weight = (80)(10)

           = 800 N

F-net = ma =(80)(4) = 320N

F-friction = weight - F-net

               =800 N - 320N

               =480N

<em>Answer</em> :

Friction = 480 N
