Molar mass of lead is 207.2 grams/mole (according to the periodic table)
Molar mass of Sulfate
Sulfur + 4 Oxygen
Molar mass of Sulfur + molar mass of 4 oxygen = 96 grams/mole for sulfate
207.2 + 96.6 = 303.8 grams/mole for Lead(II) Sulfate (I might be .5 grams of, down or up)

Answer:
Temperature will revert to room temperature after the substance reacts fully. Heat energy flows between the chemical bonds of the added substance and water to the surroundings (elsewhere in the water, the beaker, a student's hand that touches the beaker).
Explanation:
The bond length and energy of the bond formed between hydrogen (H) and astatine (At) would change if the bond order <u>increases</u> or <u>decreases</u> or when its potential energy is at the <u>lowest</u>.
<h3>What is bond length?</h3>
Bond length is also referred to as bond distance and it can be defined as an equilibrium distance between the nuclei of two (2) covalently bonded atoms in a molecule.
<h3>What is bond energy?</h3>
Bond energy can be defined as the amount of chemical energy that is required to break one mole of a given chemical bond.
In Chemistry, the bond length and energy of a molecule is typically determined by the following:
- The bond order or number of bonded electrons.
- The potential energy possessed by the molecule.
In conclusion, you can predict that the bond length and energy of the bond formed between hydrogen (H) and astatine (At) would change if the bond order increases or decreases or when its potential energy is at the lowest.
