Answer: Formation of hydrogen iodide will occur.
Explanation:
When molecule of hydrogen gas and molecule of iodine gas
collide with proper orientation and with sufficient amount of energy. This collision of the two different molecules of gases will result in the formation of hydrogen iodide.
The balanced chemical equation of the reaction will written as:
Answer:
1.48 × 10²⁴ atoms
Explanation:
Step 1: Calculate the moles of argon
Argon is a noble gas, whose molar mass is 39.95 g/mol. We will use this data to find the moles corresponding to 98.1 grams of argon.
Step 2: Calculate the atoms of argon
In order to calculate the number of atoms of argon in 2.46 moles of argon, we have to consider the Avogadro's number: there are 6.02 × 10²³ atoms of Ar in 1 mole of Ar.
