How do you calculate the rate of a reaction?

Answers

Answer 1

Rate of reaction

The rate of a reaction is a measure of how quickly a reactant is used up, or a product is formed.

There are different ways to determine the rate of a reaction. The method chosen usually depends on the reactants and products involved, and how easy it is to measure changes in them.

The mean rate of reaction can be calculated using either of these two equations:

m

n

Measuring mass

The change in mass of a reactant or product can be followed during a reaction. This method is useful when carbon dioxide is a product which leaves the reaction container. It is not suitable for hydrogen and other gases with a small relative formula mass, Mr.

The units for rate are usually g/s or g/min.

Answer 2

Rate of reaction . The mean rate of reaction can be calculated using 2 equations.

100 PTS+BRAINILIEST: Why does it get colder as you go higher through the atmosphere, if you are getting closer to the sun??

Answers

Answer/Explanation:

Heat from the sun hits the ground and is absorbed. The higher you go, it gets more colder due to the fact that the air doesn't hold onto the radiation as it goes straight through the ground, which is why the top of mountains are very cold, and people are able to die in minutes.

As you go higher, there are less air molecules and matter therefore meaning there is a lower pressure pushing down on you. Plus, when it is lower that means the particles will do some work meaning it will lose energy and when energy decreases so does the temperature and we define temperature as the average energy of the particles, in simpler words: When the pressure gets lower, the temperature also will get lower, which is why the higher you are the air temperature will get lower, and the lower you are the air temperature will get higher.

Answer:Gaseous CFCs can deplete the ozone layer when they rise due to ultraviolet radiation

Explanation:

Answer:

when chlorofloroucarbon drift upwards toward the stratospher ,they come in contact with the ozone layer .this leads to a chemical reaction where the cfcs the molecules are broken up by ultra violent radiation releasing chlorine atoms which are able to destroy ozone molecules

I am water moleculeI have to first bear the heat of sun .Then the heat evaporates me into vapours I am send to the atmosphere with my brothersThen I have to form clouds Then precipitation or density of our brothers increasesWe keep increasingThen once a time comes when we are full We then condensed down to earthWe comes back in the form of rainThen either we are stored in some place or undergroundThen people collects us from different places like pond,river etc

Hey Lenny lately I’ve been having a rough time in the water cycle. It all started when I was chilling in my favorite location the “glaciars” and suddenly the sun turned me into liquid form. Next thing I know I am hurdling down a river straight into a massive lake. Personally this is my least favorite stage of the water cycle because of kids and bacteria that lurk in the water, very scary things. I didn’t stop at the lake very long, and instead sunk into the soil in a process called collection so I could become ground water. Underground reservoir’s are much more peaceful then lakes and I wanted to stay there. However I was forced up a water well pump shortly after and sent through a long tube. Me and couple of the friends I met on the way were all dispersed over a giant grass feild. Many molecules in the group were captured by the hostile plants but I escaped through the means of evaporation. Currently I have condensed into cloud form and I am roaming the skies looking for you, when you get this let me know and I’ll percipitate in your area! P.s I found this photo of us freezing over in the ice age lollll.
