The net ionic equation of the reaction is:
- Pb²⁺aq) + 2 I(aq) → PbI2(s)
<h3>What is a net ionic ionic equation?</h3>
A net ionic equation is an equation which shows only the ions that are involved in the formation of a product in the reaction as well as the product of the reaction alone. Spectator ions are omitted.
The net ionic equation of the reaction is given below:
Pb²⁺aq) + 2 I(aq) → PbI2(s)
In conclusion, a net ionic equation does not show spectator ions.

Answer:
The temperature is 419,1 K
Explanation:
We use the formula PV=nRT T=PV/nR
T=1,5 atm x 12,6 L/0,55 mol x 0,082 l atm/K mol
T= 419,0687361 K

Answer:
d Rubidium
Explanation:
The atomic radius of an atom is the distance from the center of the nucleus to its outermost electron.
The atomic radius of elements varies in the periodic table, it increases as you go down in a group and decreases along the period from left to right.
All the elements listed: Hydrogen, Sodium, Lithium and Rubidium belong to the same group in the periodic table (group 1), Since atomic radius increases from top to bottom in a group, Rubidium has the largest atomic radius.
Covalent compounds are generally not very hard because they are formed by two or more nonmetallic atoms.
<h3>COVALENT COMPOUNDS:</h3>
Covalent compounds are compounds whose constituent elements are joined together by covalent bonds.
Covalent bonding occurs when two or more nonmetallic atoms of an element share valence electrons. This means that covalent compounds will not be physically hard since they constitute non-metals.
Examples of covalent compounds are:
- H2 - hydrogen
- H2O - water
- HCl - hydrogen chloride
- CH4 - methane
