Following laboratory safety protocols such as wearing personal protective equipment will protect John when the accident occurred.
<h3>What are laboratory safety protocols?</h3>
Laboratory safety protocols are the protocols put in place to ensure safety in the laboratory.
Laboratory safety protocols include the following:
- always wear personal protective equipment in the laboratory
- do not play in the laboratory
- do not eat in the laboratory
Following laboratory safety protocols will help protect us from accidents which occur in the laboratory.
What happened when john was carefully pouring a chemical into a beaker when the beaker slips and breaks is an example of laboratory accident.
Wearing personal protective equipment will protect John.
In conclusion, following laboratory safety protocols will protect us when accidents occur in the laboratory.

Note that the complete question is given as follows:
John is carefully pouring a chemical into a beaker when the beaker slips and breaks. How would laboratory safety protocols help John?
D because wants you add the equation it should increase temp but decrease the value in pressure
The given equation from the problem above is already balance,
N2O5 ---> 2NO2 + 0.5O2
Since, in every mole of N2O5 consumed, 2 moles of NO2 are formed, we can answer the problem by multiplying the given rate, 7.81 mol/L.s with the ratio.
(7.81 mol/L.s) x (2 moles NO2 formed/ 1 mole of N2O5 consumed)
= 15.62 mol/L.s
The answer is the rate of formation of NO2 is approximately 15.62 mol/L.s.
Convection
Explanation:
Convection is form of heat transfer by which heat moves through liquid and circulates due to density differences.
There are three major forms of heat transfer:
- Conduction is form of heat transfer that involves contact between two bodies in which collision between their molecules caused heat exchange from the hot body to the cold one.
- Radiation is a form of heat transfer that does not involve contact. It involves the use of electromagnetic waves of different forms.
- Convection occurs in fluids in which heat transfers as a result of movement of molecules of the medium from one point to the other. The hotter body becomes lighter and rises whereas the colder ones sinks.
