For a chemical reaction, the results would be the same with different amounts of barium chloride present if barium chloride is not the limiting reactant of the reaction. The limiting reactant is the substance that is totally consumed when the reaction proceeds to completion. In other words, it dictates the amount of products that will be produced. Otherwise, if barium chloride is the limiting reactant, the amount of barium chloride present would definitely affect the results.
Is correct hope this helps i have done this before
Answer:
______is used in production of hard disk.
Explanation:
0.0013% = 0.0013 g/100 ml water, or 1.3 mg/100 ml water
so for 145 mg, you need 145×100/1.3 = 11154 ml water or 11.154 L of water. Lead is a toxic metal that affects the central nervous system.
Extensively talking, the frightened gadget is organized into essential parts, the central nervous system(CNS) and the peripheral nervous system (PNS). The CNS is the processing center of the frame and includes the mind and the spinal cord. Both of these are protected through 3 layers of membranes referred to as meninges.
The principal anxious gadget is the frame's processing center. The brain controls most of the capabilities of the frame, inclusive of cognizance, movement, thinking, speech, and the five senses of seeing, listening to, feeling, tasting and smelling. The spinal twine is an extension of the mind.
The brain is what controls all the frame's features. The spinal twine runs from the brain down via the again. It carries threadlike nerves that department out to each organ and frame part. This network of nerves relays messages from side to side from the mind to distinctive parts of the body.

The reaction is not balanced
<h3>Further explanation</h3>
Given
Reaction
2Fe(s)+3O₂(g)⇒2Fe₂O₃(s)
Required
The number of atoms
Solution
In a balanced chemical equation, the number of atoms in the compound that reacts (the reactants and products) will have the same number
Reactants : Fe(s)+O₂(g)
Fe = 2 atoms
O = 3 x 2 = 6 atoms
Products : Fe₂O₃(s)
Fe = 2 x 2 = 4 atoms
O = 2 x 3 = 6 atoms
The reaction is not balanced because the number of Fe atoms is not the same
The balanced reaction should be:
4Fe(s)+3O₂(g)⇒2Fe₂O₃(s)
