Answer:</h3>
LiOH(aq) +HCl(aq)→ LiCl(aq) + H₂O(l)
Salt formed is LiCl
<h3>
Explanation:</h3>
- Arrhenius acid refers to a substance that ionizes in water to generate protons or hydrogen ions.
- Examples of Arrhenius acid include acids such as HCl, H₂SO₄ and HNO₃.
- A reaction between Lithium hydroxide and an Arrhenius acid such as HCl will yield a salt and water.
That is;
LiOH(aq) +HCl(aq)→ LiCl(aq) + H₂O(l)
- The salt formed is LiCl
- The reaction is an example of neutralization reaction.
These waxes are highly hydrophobic (repellant) of water, so the correct answer would be D) repel.
The wax coating put on the car creates a water repellant sheila that causes the water to bead up on the surface of the wax, rather than directly impacting the paint and surface of the body of the car. This prolongs the life and quality of the appearance of the car.
Answer:
d. white blood cells
Explanation:
It is the white blood cells that have the least tendency to cross the blood- brain barrier.
Blood- brain barrier is psychological barrier and restricts substances that circulate into the blood from crossing over the central nervous system.
Water, glucose as well as sodium ions can easily cross the barrier. As these are good for body supply energy to the brain.
You must first calculate the total weight of 1 mole of the substance. You do this by finding the molar weights on the periodic table of each of the elements in the compound:
So now we take the amount of each element that is given in the compound and divide it by the total mass of the compound:
Carbon: 96.08g
Carbon = 49.48%
Nitrogen: 56.028g
Nitrogen = 28.85%
Oxygen: 31.998g
Oxygen = 16.48%
Monoprotic acid are acids having
only one hydrogen atoms after dissociation into ions from its compound. The
monoprotic acid from among the following is HCl. The answer is letter D. HCl →
H+ + Cl-. Note that there is only one H+ ion upon dissociation.
