Aww man, I love these types of problems!!!
So, it's a simple formula:
P1*V1/T1=P2*V2/T2
In this case, we remove V(volume) as there is none listed, leaving this:
P1/T1=P2=T2
Think you got it from here? All you gotta do is plug in the numbers and solve
If you have any further problems, just let me know!!
An atom consist of mainly two parts, namely nucleus and electrons. In the nucleus, there are groups of protons and neutron DENSELY packed, each element has its own atomic number(number of protons) but can have different no. of neutron (isotop). within the proton and neutron, there are subatomic particles called quarks. Talking about the electrons, they move very quickly arround the nucleus and there are different energy level for electron to switch between. In chemical reaction, we are only concerning the no. of valence electrons.
Can you follow me and like me please?
Answer is B.
Explanation:
A physical change is one in which there is no change in chemical composition of a substance. while a process in which there is change in chemical composition it is called a chemical change.
Answer:
Here it would be A,B and C because all the examples are violating safety precautions. They are all examples of un safe signs.
Hope this helps
