Answer:
the candle is still solid..................in this case, yes!
Explanation:
it is still solid because the molecules are packed together tighter than the molecules in a liquid or gas.
Answer:
V2 = 5.8 L
Explanation:
T1 = 50°C = 323 K
V1 = 5L
T2 = 100°C = 373 K
V2 =?
According to Charles's law,
V1/T1 = V2/T2
---> V2 = (T2/T1)V1 = (373K/323K)(5 L)
= 5.8 L
it turns yellow to orange
Answer: [He] 2s² 2p¹
Explanation:
1) B is boron
2) Atomic number of boron is 5, meaning that it has 5 protons and 5 electrons.
3) So, the ground state electron configuration is 1s² 2s² 2p¹
4) Using the noble-gas shorthand notation means that you start with the configuration of the noble gas previous to the element.
In this case, the noble gas that is before B is He.
So, the noble-gas shorthand notation for B is [He] 2s² 2p¹
