Explain how electrically neutral objects can become electrically charged even though charge cannot be created or destroyed.

1 answer:

6 0

Electrically neutral objects can become charged when they gain or lose electric charges. When an object is electrically neutral then the overall charge of the object is Zero. If a neutral object gains negative charges then it will become negatively charged, and if it looses the negative charges (electrons) then it becomes positively charged.

Explain Charles law

kodGreya [7K]

"Charles Law" is the relationship between "volume-temperature" (V ∝ T).

Explanation:

Charles Law is basically volume-temperature relationship (V ∝ T). French scientist “Jacques Charles” in 1787 studied effect of temperature on the volume of gases at constant pressure, which described how gases manage to expand when heated. Law stated as “At constant pressure, the volume of a given "mass" of a gas decreases or increases by 1/273 of its volume at $0^{\circ} \mathrm{C}$ for each one degree rise or fall in temperature”. Formula derived from law is as follows: $\mathbf{V}_{\mathbf{t}}=\mathbf{V}_{0}[\mathbf{1}+\mathbf{t} / \mathbf{2} 7 \mathbf{3}]$ here ${V}_{0}$ is volume of given mass of a gas at $0^{\circ} \mathrm{C}$ , ${V}_{t}$ is its volume at any temperature $t^{\circ} \mathrm{C}$ . Application of Charles law is hot air balloons.

if one mole of calcium carbonate (the limiting reactant) is used, how much calcium chloride should the reaction produce? look at

salantis [7]

Answer:

The answer to your question is 111 g of CaCl₂

Explanation:

Reaction

2HCl + CaCO₃ ⇒ CaCl₂ + CO₂ + H₂O

Process

1.- Calculate the molecular mass of Calcium carbonate and calcium chloride

CaCO₃ = (1 x 40) + (1 x 12) + ((16 x 3) = 100 g

CaCl₂ = (1 x 40) + (35.5 x 2) = 111 g

2.- Calculate the amount of calcium chloride produced using proportions.

The proportion CaCO₃ to CaCl₂ is 1 : 1.

100 g of CaCO₃ ------------- 111 g of CaCl₂

Then 111g of CaCl₂ will be produced.
