Why can’t y’all do more points then 5? why can’t it be like 20-10
Basically all of the elements found in Group I of the periodic table also have this property. The ability to easily give up a single valence electron.
An electron weighs 1/1836 atomic mass unit and, on the other hand, an alpha particle weighs 4 atomic mass unit.
<span>4 amu / (1/1836 amu) = 7344 </span>
<span>Therefore, an alpha particle is 7344 times heavier than an electron.
Hope this answers the question. Have a nice day.</span>
Since the configuration contains the number 2s and 2p, you can assume that it is in period 2 of the periodic table. By noble gas shorthand, you start with helium, which is atomic number 2. 2s²2p^4 has 2+4 = 6 valence
Add 2+6 = 8, which is Oxygen.
Explanation:
The given data is as follows.
q = 69.0 kJ = 69000 J (as 1 kJ = 1000 J),
mass (m) = 8.10 kg = 8100 g (as 1 kg = 1000 g)
= (33.9 + 273) K = 306.9 K
C = 4.18 J/gK
As we know that the relation between heat and change in temperature is as follows.
q = 
Putting the values into the above formula to calculate the final temperature as follows.
q = 
69000 J =
69000 J =
= 2.037 K
= (2.037 + 306.9) K
= 308.9 K
or, = 309 K (approx)
Thus, we can conclude that the new temperature of the water bath is 309 K.
