Answer: The atomic number is the number of protons in an atom of an element. In our example, krypton's atomic number is 36. This tells us that an atom of krypton has 36 protons in its nucleus.
Explanation:
Answer:
= 3.56 atm
Explanation:
Using Boyle's law which states that the volume of a given mass of gas is inversely proportional to the pressure and Charles law states the volume of a given mass of gas is directly proportional to the temperature.
P1/T1 = P2/T2
P1 = 3.1 atm, T1 = 100'C = 100+273 = 373K
T2 = 155'C = 155 + 273 = 428K
3.1/ 373 = P2 / 428
Cross multiply
373 × P2 = 3.1 × 428
373×P2 = 1326.8
Divide both sides by 373
P2 = 1326.8 ÷ 373
P2 = 3.56 atm

Well there are plenty of benefits and consequences.
But one would be the ability to do certain tasks without actually having to do them. A consequence could be on the environment. For example, the use of a car plays a big part on the environment involving smog.
Hope this helps!
I took the test to find out it's not A or D so it's either B or C.
Elements Y and elements Z would have similar properties due to the fact that they both posses the same number of valence electrons. They both have a single valence electron that determines the corresponding elements bonding properties and the fact that it can either donate 1 valence electron to produce an ion that would be attracted to another atom, that is also an ion. Assuming that these elements are group 1 elements, they do not undergo in covalent bonding.
