What is a sentence for weathering

Answer:

The molarity is 0.189

Explanation:

Molarity is a measure of concentration of a solution that indicates the number of moles of solute that are dissolved in a given volume. In other words, the molarity indicates the amount of moles of solute that appear dissolved in each liter of the mixture.

Molarity is determined by the expression:

Molarity is expressed in units ().

So, you need to know the amount of moles of ZnSO₄. Then you must know the molar mass. If:

• Zn: 65 g/mol
• S: 32 g/mol
• O: 16 g/mol

the molar mass of ZnSO₄ is:

ZnSO₄= 65 g/mol + 32 g/mol + 4* 16 g/mol= 161 g/mol

Then you can apply a rule of three as follows: if 161 g of ZnSO₄ is contained in 1 mole, 13.7 g in how many moles are they?

moles=0.085

Then you know:

• number of moles of solute= 0.085 moles
• Volume= 450 mL (Being 1 L=1,000 mL)

Replacing in the definition of molarity:

Molarity=0.189

The molarity is 0.189

The correct answer is option B. Metallic.

What explains the structure of metals and delocalized electrons?

Metal is composed of a huge structure of atoms arranged in a regular pattern. Electrons from the outer shell of a metal atom are delocalized and can move freely throughout the structure. This sharing of delocalized electrons results in strong metal bonds.

Metallic bonds are electrostatic attraction between metal cations and the negatively charged ocean of delocalized electrons. The sea of ​​delocalized electrons contains only valence electrons, not core electrons.

B.metallic is the answer hope this helped

Explanation:

In gases, the molecules are held together by weak Vander waal forces. Due to this they have more kinetic energy and hence, more number of collisions take place between the molecules of a gas.

Therefore, they tend to diffuse at a faster rate and distance traveled by them is more as compared to the distance traveled by the molecules of a liquid.

On the other hand in liquids, the molecules are held by more strong intermolecular forces of attraction as compared to gases but not strong enough as they are in solids. Due to this molecules of a liquid are able to slide past each other. Hence, they have medium kinetic energy.

Therefore, less number of collisions take place between molecules of a liquid as compared to gases.

Thus, we can conclude that particles collide in gas so, substance X is a gas.
