How does sodium become a negative ion of neon

Explain the connection between atoms and electricity

zaharov [31]

Answer:

The protons and electrons of an atom are attracted to each other. They both carry an electrical charge. Protons have a positive charge (+) and electrons have a negative charge (-). The positive charge of the protons is equal to the negative charge of the electrons.

A drop of vinegar ( a weak acid ) is placed on a sample of each of the materials below. Which will show the most active reaction

professor190 [17]

Answer: Option (B) is the correct answer.

Explanation:

Marble is also known as calcium carbonate and its chemical formula is $CaCO_{3}$ .

When it combines with vinegar then it results in the formation of calcium acetate which is a water soluble compound along with the release of carbon dioxide which occurs in the form of bubbles and water.

The reaction is as follows.

$CaCO_{3} + CH_{3}COOH \rightarrow Ca(CH_{3}COOH)_{2} + H_{2}O + CO_{2}$

Whereas vinegar being a weak acid will not react with glass, copper and steel.

Calculate the volume of chlorine at stp that would be required to act completely with 3.70g of dry slaked line

myrzilka [38]

Answer:

The volume required is 2.24L

Explanation:

The slaked lime Ca(OH)2, reacts with chlorine, Cl2, as follows:

6Cl₂(g) + 3Ca(OH)₂(s) → Ca(ClO₃)₂ (aq) + 2CaCl₂ (aq) + 6HCl (aq)

<em>Where 6 moles of chlorine react with 3 moles of slaked llime,</em>

<em />

To solve this question we must find the moles of slaked lime added. With these moles we can find the moles of chlorine required and its volume at STP as follows:

<em>Moles Ca(OH)2 - Molar mass: 74.093g/mol-</em>

3.70g * (1mol / 74.093g) = 0.0500 moles Ca(OH)2

<em>Moles Cl₂:</em>

0.0500 moles Ca(OH)2 * (6 mol Cl₂ / 3 mol Ca(OH)2) =

0.100 moles Cl₂

Now using PV = nRT

nRT / P = V

<em>Where n are moles: 0.100 moles</em>

<em>R is gas constant = 0.082atmL/molK</em>

<em>T is absolute temperature = 273K at STP</em>

<em>P is pressure = 1atm at STP</em>

<em>And V is volume, our incognite:</em>

<em />

0.100mol*0.082atmL/molK*273K / 1atm = V

2.24L = Volume of Cl₂

<h3>The volume required is 2.24L</h3>

Eric pours some iced tea into a glass. When he puts the iced tea in the glass, the energy of the glass decreases. What must be t

nekit [7.7K]

Iced tea's energy increases while the energy of the glass decreases.

<h3>What is energy?</h3>

Energy is the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other forms

Iced tea's energy increases while the energy of the glass decreases because the ice is getting warmer so the glass is also getting warmer. meaning that the glass is decreasing in energy while the ice tea is increasing in energy.

Hence, iced tea's energy increases while the energy of the glass decreases.

A combustion reaction will always be associated with a change in entropy that will be:________.

Alex Ar [27]

Answer:

Option (A) : Positive

Explanation:

A combustion reaction will always be associated with a change in entropy that is Positive due to the gaseous products released. Hence, there is a large positive entropy change.
