Answer:
Hydrogen bonding
Explanation:
Water is a compound found readily in nature. It is made up of interatomic forces of covalent bonds that connects the hydrogen and oxygen bonds together in a definite ratio.
- The intermolecular forces are responsible for the physical properties of substances.
- These forces allows a compound to behave in certain ways.
- In water, the intermolecular bonding present are the very strong hydrogen bonds.
- For this bond type, the hydrogen of one water molecule is firmly attached to the oxygen of another water molecule.
- The bonds are very strong forces.
Answer:
It results from microscopic bumps and ridges
It causes a change in motion
It is opposite to the direction of the motion.
It is parallel to the surfaces that rub together.
Explanation:
Rockets, aerial shells, mines, cakes, firecrackers, wheels, fountains (gerbs), lancework, Roman candles and sparklers.
Answer:
200 g/L
Explanation:
The concentration of a solution (also called molarity) can be calculated with the formula:
where
m is the mass of the solute
V is the volume of the solution
For the solution in this problem we have:
m = 50g is the mass of the solute
V = 250 mL = 0.250 L is the volume of the solution
Therefore, the concentration of the solution is:
Answer is: D. 6.02 x 1023.
Because this is Avogadro constant<span> (the number of </span>constituent particles, in this example atoms of gold<span> that are contained in the </span>amount of substance<span> given by one </span>mole). <span>The </span>mole<span> is the </span>unit of measurement<span> for </span>amount of substance, t<span>he mole is an </span>SI base unit<span>, with the unit symbol </span>mol<span>.</span>
