Answer:
15mL
Explanation:
Step 1:
Data obtained from the question
This includes the following:
Molarity of the base (Mb) = 3M
Volume of base (Vb) =.?
Volume of acid (Va) = 30mL
Molarity of the acid (Ma) = 0.75M
Step 2:
The balanced equation for the reaction.
H2SO4 + 2NaOH —> Na2SO4 + 2H2O
From the balanced equation above,
The mole ratio of the acid (nA) = 1
The mole ratio of the base (nB) = 2
Step 3:
Determination of the volume of the base.
This can be achieved as follow:
MaVa/MbVb = nA /nB
0.75 x 30 / 3 x Vb = 1/2
Cross multiply
3 x Vb = 0.75 x 30 x 2
Divide both side by 2
Vb = (0.75 x 30 x 2) /3
Vb = 15mL
Therefore, the volume of the base needed is 15mL.
Answer:
Explanation:
Since it is alkane, The suffix used will be "-ane".
Prefix for 4 carbons => "but-"
Hence, the name:
BUTANE
Hope this helped!

CFL means compact fluorescent lamp
It can save five times its purchase price in electricity cost because it contains toxic mercury that is equivalent in working: electrons that are bound to mercury atoms are excited to states where they will radiate ultraviolet light as they return to lower energy level, this ultraviolet light will be converted into visible light as it strikes to the coating of the bulb. Like LED that is high-efficiency house lighting.
Answer:
Methane is an odorless, colorless, flammable gas. It is used primarily as fuel to make heat and light. It is also used to manufacture organic chemicals. Methane can be formed by the decay of natural materials and is common in landfills, marshes, septic systems and sewers
