P1V1T1=P2V2T2 Add 273 to convert degrees Celsius to Kelvin:
∴200×25/298=250×V2/273, ∴V2=200×25×273/298×250, ∴V2=18.32L
<h3>Where is the volume equation?</h3>
The basic formula for volume is length, breadth, and height, as opposed to length, width, and height for the area of a rectangular shape. The calculation is unaffected by how you refer to the various dimensions; for instance, you can use "depth" instead of "height."
<h3>What is chemistry using volume units?</h3>
Volume, which is measured in cubic units, is the 3-dimensional space occupied by matter or encircled by a surface. The cubic meter (m3), a derived unit, is the SI unit of volume.

Okay so we are given these requirements:
element which can be used to stuff
bottles that enclose ancient paper
must be a gas at room temperature
must be denser than helium
must not react with other elements
The only element that comes into my
mind is:
<span>Argon</span>
6 is the fourth significant figures
if the number behind it is 5 or more then 5, you must add 1 to the number and ALL the number behind it will turn into 0
so that the answer is 42560
<span>Answers are:
-4 for C in CH4, because carbon has greater electronegativity than hydrogen and he attracts shared electrons.
</span><span>+4 for C in CO2, because carbon has smaller electronegativity than oxygen.
</span><span>+1 for H in both CH4 and H2O, because hydrogen has amaller electronegativity than both carbon and oxygen.
</span>
Answer:
1. True
2. False
3. False
4. True
Explanation:
A lab is an abbreviation for laboratory and it can be defined as a building that is equipped with scientific equipments and apparatus, which are used for performing scientific experiments, manufacturing of chemicals and drugs, research, testing and analysis of hypothesis in order to establish a theory.
Generally, laboratory scientists, technicians, students and anyone going into a laboratory is prohibited from taking in edible items such as food and water.
Basically, all laboratories are required to place a visible warning sign around the lab prohibiting the bringing in and ingestion of food in any form.
1. True: Tobacco products of all kinds are prohibited in lab.
2. False: Beverages are allowed in lab as long as they are in containers with lids. It's completely prohibited from the lab so as to prevent food poisoning.
3. False: Chewing gum is okay in the lab as long as you don't blow bubbles.
4. True: Food items should not be brought into the lab.
