What is mass?

A body's mass is an inherent quality. Prior to the discovery of a atom or particle physics, it was widely considered to be tied to the amount of matter inside a physical body. It was discovered that, despite having the very same quantity of matter in theory, different atoms and elementary particles have varied masses.

There are various conceptions of mass in contemporary physics that are theoretically different but physically equivalent. The resistance of the body to acceleration in the presence of a net force can be measured experimentally as mass. The gravitational pull an object has on other bodies is also influenced by its mass.

2 Al + 3 Cl[tex]_2[/tex] → 2 Al C l[tex]_3[/tex]

mole of Al =  135.0/ 26=5.19mol

mole of Cl[tex]_2[/tex] = 75.0/ 35 =2.14 mol

mass of aluminum chloride =  56.8g

Limiting reagent = Al

excess reactant =  Cl[tex]_2[/tex]

Therefore, 56.8g of aluminum chloride will be produced if the reaction begins with 135.0 g Al and 75.0 g chlorine gas.

Why the bond in water molecule os polar covalent bond, while than in chlorine molecule is pure covalent bond? Give reason? ​

Answers

Explanation:

The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles - a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side). We say that the water molecule is electrically polar.

After six hours, the researcher observes and sketches the two cells as shown. What change in the cells occurred during the six hours the cells remained undisturbed? A.Osmosis occurred in the salt water cell sample because the water from inside the cell moved out of the cell to a lower concentration, causing the cell to shrink. B.Osmosis occurred in the freshwater cell sample because the water from outside the cell moved into the cell to a higher concentration, causing the cell to grow. C.Osmosis occurred in the salt water cell sample because the salt from outside the cell moved into the cell to a lower concentration, causing the cell to shrink.

(Help would be greatly appreciated, chemistry is not my strong suit) How many moles of NaCl are present in a solution with a molarity of 8.59M and 125mL of a solution?
1. 1.07g
2. 62.7mol
3. 1.07mol
4. 62.7g

Answers

Molarity is a unit of concentration defined as the number of moles of solute (the substance being dissolved) per volume of solution (the solvent in which all the solute is dissolved). Mathematically, molarity is expressed as

[tex]M = \frac{\text{ mol solute}}{\text{ L solution}}[/tex].

In this question, we are given the molarity and the volume of a solution of NaCl. We can use this information to calculate the number of moles of NaCl present in the solution. Rearranging the equation to solve for moles of solute, we multiply the molarity by the volume of the solution (the units for volume must be in liters, so 125 mL is expressed as the equivalent 0.125 L):

[tex](8.59 \text{ M})(0.125 \text{ L}) = 1.07 \text{ moles of NaCl}.[/tex]

The question asks for the number of moles of NaCl in this solution, so number 3 would be correct.

Sulfuric acid is an important chemical in industrial production of many products. In the “old” days, it was called oil of vitriol. It is commonly dyed brown now to alert people to its hazards because it is hugely corrosive. It is commonly found in car batteries. What is the molarity of 25.9 moles of sulfuric acid dissolved in 4.00 L of solution?

Answers

Answer:

6.475 M

Explanation:

Number of moles = 25.9 moles

Volume = 4.00 L

Molarity = ?

The relationship between the quantities is given as;

Molarity = Number of moles / Volume

Molarity = 25.9 / 4

Molarity = 6.475 M
