Answer:
0.25M HCl
Explanation:
The reaction of HCl with NaOH is:
HCl + NaOH ⇄ H₂O + NaCl
<em>Where 1 mole of HCl reacts per mole of NaOH</em>
The end point was reached when the student added:
0.0500L × (0.1mol / L) = 0.00500 moles of NaOH
As 1 mole of HCl reacted per mole of NaOH, moles of HCl present are:
<em>0.00500 moles HCl</em>
The volume of the sample of hydrochloric acid was 20.0mL = 0.0200L, and concentration of the sample is:
0.00500 mol HCl / 0.0200L = <em>0.25M HCl</em>
Since there is more energy added as heat rises, the particles disperse and have larger movements.
Answer:
NH₄Cl ------> NH₃ + HCl
Explanation:
Ammonium Chloride =(NH₄Cl
Ammonia = NH₃
Hydrochloric Acid = HCl
NH₄Cl ------> NH₃ + HCl
In decomposition reaction, the reactant is breaking down into smaller parts. In this case, all of the coefficients are 1. The reaction is already balanced.
Potential energy<span> is the stored </span>energy<span> in an object due of its position or its configuration where as </span>Kinetic energy<span> is the </span>energy<span> which a body possesses because of its motion.</span>
Answer:
C
Explanation:
If you move the decimal to the left it transforms the expression into scientific notation.
