Answer:
The oppositely charged ions form an electrostatic attraction, which is the ionic bond. The compound potassium fluoride (KF) results, and since the potassium and fluoride ions have equal but opposite charges, the compound is neutral (but not the individual ions in the compound).

<em><u>Hydrochloric acid</u></em> is the acid in gastric juice that is lethal to many pathogens.
This hydrochloric acid activates pepsinogen into the pepsin enzyme which then aids in the digestion by breaking down the bonds linking amino acids. This process is known as proteolysis. In immunology, it has been postulated that one main function of the inherent hydrochloric acid in gastric juices is to prevent microorganisms from reaching the small intestine where it can potentially cause diseases or worse, get access to other parts of the human body.
Answer:
Raindrops in the air
Explanation:
light refracts through water, and raindrops are water.
Answer:
Volume
Explanation:
Density:
Density is equal to the mass of substance divided by its volume. In order to find the density of earth when mass is given we have to calculate its volume. The volume of earth is calculated by using the volume formula for sphere. i.e 4/3 π r³. we also require radius to find the volume and we know that
Diameter = 2 × radius
The diameter of earth equator is 12756.75 Km. So we calculate the radius by dividing the diameter by 2. Then by putting the value of radius in 4/3 π r³ we will get the volume and then we can calculate the density of earth.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
