Answer:
Proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10−27 kg, which is 1,836 times the mass of an electron.
Explanation:
Answer:
D. 9.
Step-by-step explanation:
One formula unit of NaOH contains <em>three atoms</em>: 1 Na, 1 O, and 1 H.
3 formula units × (3 atoms/1 formula unit) = 9 atoms
Answer:
true

Answer:
esters
Explanation:
The -OR group of the alcohol replaces the -OH of the carboxylic acid, forming an ester. See attachment for condensed mechanism.
Lithium is one of element of group 1 of periodic table.
Lithium has the smallest radius than as compared to the other elements, thus the density of the alkali metal is also less.
Lithium when added to water it floats, because of lower density. It eventually fizzes and becomes smaller.
The reaction on lithium and water is:
2Li + 2H₂O --> 2LiOH + H₂ (g)
The hydrogen gas which is liberated is highly flammable.
Thus, lithium salts are insoluble in water.
Density is defined as the mass of a substance per unit volume.
Density = Mass ÷ Volume.
