M<span>olar mass Hg = 200.5920g/mol </span>
<span>Hg = 24.1/200.5920 = 0.120mol </span>
<span>234.32K liquid to 25C (298.15K) liquid </span>
<span>h = (0.120)(28.0)(298.15 - 234.32) = 214.4688 J </span>
<span>234.32K liquid to 234.32K solid </span>
<span>h = (0.120)(2.29) = 0.2748 kj </span>
<span>total heat = 0.2145 + 0.2748 = 0.4893 kJ</span>
Answer:
Metal is named first
Explanation:
Binary compounds:
The compounds which are made up of the atoms of only two elements are called binary compounds.
For example:
The following compounds are binary:
HCl
NaCl
HCl is binary because it is composed of only hydrogen and chlorine.
Sodium chloride is also binary compound composed of only two element hydrogen and chlorine.
When naming these compounds the name of metal or cation is written first and anion is written after the cation. The anions are non meals.
The anion name is end with suffix " ide".
such as sodium chloride.
To get the mass of the glass watch. It’s very simple. Take all 4 numbers 99.997, 100.008, 100.011, 100.005 add them together and then divide them by 4 bc there were 4 numbers to begin with.
The mass of the glass is- 100.00525 g
