Volume of base(NaOH)= Vb =5 mL
Concentration of base(NaOH)= Mb =2 M
Volume of acid(HCl)= Va =10 mL
Concentration of acid(HCl)= Ma = ?
Now,
Ma*Va = Mb*Vb
Ma*(10) = (2)*(5)
Ma= 1M
Answer:
A strong base is something like sodium hydroxide or potassium hydroxide which is fully ionic. You can think of the compound as being 100% split up into metal ions and hydroxide ions in solution.
Explanation:
Answer:
B) Protons and Neutrons
Explanation:
In every atom, there is a Nucleus which contains protons and Neutrons. Protons being positive and Neutrons not having a charge (neutral).
Answer:
15.1 g/mL
Explanation:
<em>The density of a substance is defined as the ratio of the mass of the substance and the volume of the substance. Mathematically, it is expressed as:</em>
Density = mass in grams/volume in mL
In this case, the mass of the metal = 30.2 g
Volume of the metal = volume of water displaced by the metal.
<em>The volume of water displaced by the metal can be calculated as the final volume of water after placing the metal - initial volume of water before placing the metal.</em>
Hence, volume of metal = 22.0 - 20.0 mL = 2.0 mL
Density of metal = 30.2/2.0 = 15.1 g/mL
The density of the metal is 15.1 g/mL
<u>The identity of the metal is not in the table.</u>
