Answer:
Amount of 
produced will be half of its original value.
Explanation:
Balanced reaction: 
According to balanced equation, 1 mol of HCl reacts with 1 mol of NaOH to produce 1 mol of
If amount of reactants (NaOH and HCl) are halved then we can write-
0.5 mol of HCl reacts with 0.5 mol of NaOH to produce 0.5 mol of .
So, it is evident that amount of to be produced will be half if amount of reactants are halved.
Answer:
The boiling point of the liquid is 47.368°C
Explanation:
Stability of atoms is determined by neutron:proton ratio. This n/p ratio is 1:1 for elements below atomic number 20. Hope this helps.
Answer:
A. Soaps react with ions in hard water to create a precipitate.
B. Soaps are both hydrophobic and hydrophilic.
D. Soaps should be weakly alkaline in solution.
Explanation:
A. Hard water contains <u>magnesium and calcium minerals</u> like calcium and magnesium carbonates, sulfates and bicarbonates. As soon as these minerals come in contact with soap their ions like Mg²⁺ & Ca²⁺ form precipitates.
B. Soap are both hydrophilic and hydrophobic. They reason why they exhibit both the properties is really important for their functionality. The hydrophobic part of soap makes interaction with oil/dust particles while the hydrophilic part makes interaction with water. When the cloth is rinsed the dirt/soap particles are removed from the dirty clothes thereby making them clean.
C. Soaps have alkaline pH i.e. more than 7 that is why they have bitter taste.
Answer:
Everything is composed of atoms! which are the indivisible building blocks of matter and cannot be destroyed. All atoms of an element are identical. The atoms of different elements vary in size and mass.
