The molar mass of Li->7g/mol
If 1mol of Li is 7g/mol
1.50mol of Li would be 10.5g/mol
The reactant is Mercury (II) Oxide while the products are Mercury and Oxygen separately.
This is because the reactants are typically always on the left side of the yields symbol. In this decomposition reaction, it would still be the same as at the end of the reaction, there were to products produced: Mercury and Oxygen.
Products tend to always be on the right side of the yields symbol, they're what comes out of a reaction no matter what type.
Hope this helps!
The maximum temperature : a. 745 K
<h3>Further explanation</h3>
Given
Gas at 25°C(298 K) and at a pressure of 0.800 atm
Final pressure = 2 atm
Required
Final temperature
Solution
Gay Lussac's Law
When the volume is not changed, the gas pressure in the vessel is proportional to its absolute temperature
Input the value :
T₂=(P₂T₁)/P₁
T₂=(2 atm x 298 K)/0.8 atm
T₂ = 745 K = 472 °C
The chlorine atom bonds through covalent bond to obtain an octet structure so two atoms of 2,8,7 come together and HCl consists of both metal and nonmetal which is the the covalent bonding principle so H and Cl share the 8 valence electrons to obtain an octet structure.
