Answer:
Hydrosulfuric acid will act as limiting reactant.
Explanation:
Given data:
Mass of iron(III) chloride = 3243.0 g
Mass of hydrosulfuric acid = 511.8 g
Limiting reactant = ?
Solution:
Chemical equation:
2FeCl₃ + 3H₂S → Fe₂S₃ + 6HCl
Number of moles of iron(III) chloride:
Number of moles = mass/molar mass
Number of moles = 3243.0 g/ 162.2 g/mol
Number of moles = 20 mol
Number of moles of hydrosulfuric acid:
Number of moles = mass/molar mass
Number of moles = 511.8 g/ 34.1 g/mol
Number of moles = 15 mol
Now we will compare the moles of both reactant with products
FeCl₃ : Fe₂S₃
2 : 1
20 : 1/2 ×20 = 10
FeCl₃ : HCl
2 : 6
20 : 6/2 ×20 = 60
H₂S : Fe₂S₃
3 : 1
15 : 1/3 ×15 = 5
H₂S : HCl
3 : 6
15 : 6/3 ×15 = 30
Hydrosulfuric acid producing less number of moles of product thus, it will act as limiting reactant.
One oxygen atom shares two electron with two hydrogen atoms in this way water molecules are formed. The bond between oxygen and hydrogen is covalent bond.
<h3>What is covalent bond ?</h3>
An electron exchange that results in the formation of electron pairs between atoms is known as a covalent bond. Bonding pairs or sharing pairs are the names given to these electron pairs.
Covalent bonding is the stable equilibrium of the attractive and repulsive forces between atoms when they share electrons.
According to the amount of shared electron pairs, there are three different forms of covalent bonds. single covalent bond is one type of covalent bond. covalent double bond and covalent triple bond.
Thus, option B is correct .

Answer:
Look at explanation
Explanation:
Size of particles increases, rate of reaction decreases, and vise versa
Catalyst causes the rate of reaction to increase
Concentration increases, rate of reaction increases, and vise versa
Temperature increases, rate of reaction increases, and vise versa
Netrons ( if not right sorry)
Most young children already have plenty of energy without the need for coffee to sustain them throughout the day, so at least until they are 12 years old, it's best to avoid giving your kids coffee if possible
