For this discussion, respond to the following... An electron falls through a distance d in a uniform electric field of magnitude
mars1129 [50]

The electron should experience a greater acceleration due to it's significantly smaller mass and should fall through distance "d" in a shorter amount of time.

<u>Explanation:</u>

The electron force can be expressed as F=qE. According to Newton's second law of motion force can be expressed as F=ma. This can be written as a=F/m. Substituting electric force expression for "F" in this equation, we get a=qE/m. This means acceleration is conversely proportional to mass and directly to electric field and charge. This means that proton having significantly larger mass than electron should experience smaller amount of acceleration and would take longer to fall at distance "d".

On the other hand, the electron would experience greater acceleration due to it's significantly smaller mass and would fall faster at distance "d", unlike the situation of proton.

For each of the acid–base reactions, calculate the mass (in grams) of each acid necessary to completely react with and neutraliz
LiRa [457]

Acid-base neutralization reaction is defined as reaction of acid with base to form corresponding salt and water. Strong acid and base completely neutralize each other.

(a) The acid base neutralization reaction is as follows:

HCl(aq)+NaOH(aq)\rightarrow H_{2}O(l)+NaCl(g)

From the above balanced chemical reaction, 1 mol of NaOH completely reacts with 1 mol of HCl. The mass of NaOH is given 4.85 g, convert this into number of moles as follows:

n=\frac{m}{M}

Molar mass of NaOH is 39.997 g/mol, thus,

n=\frac{4.85 g}{39.997 g/mol}=0.121 mol

Thus, 0.121 mol of NaOH reacts with same amount of HCl and number of moles of HCl will be 0.121 mol.

Since. molar mass of HCl is 36.46 g/mol, thus, mass can be calculated as follows:

m=n\times M=0.121 mol\times 36.46 g/mol=4.421 g

Therefore, 4.421 g of HCl completely reacts with 4.85 g of NaCl.

(b) The acid base neutralization reaction is as follows:

2HNO_{3}(aq)+Ca(OH)_{2}(aq)\rightarrow 2H_{2}O(l)+Ca(NO_{3})_{2}(aq)

From the above balanced chemical reaction, 1 mol of Ca(OH)_{2} completely reacts with 2 mol of  HNO_{3}. The mass of Ca(OH)_{2}   is given 4.85 g, convert this into number of moles as follows:

n=\frac{m}{M}

Molar mass of Ca(OH)_{2}  is 74.093 g/mol, thus,

n=\frac{4.85 g}{74.093 g/mol}=0.06545 mol

Thus, 0.06545 mol of Ca(OH)_{2} reacts with 2\times 0.06545 mol=0.13091 mol of HNO_{3}

Since. molar mass of HNO_{3} is 63.01 g/mol, thus, mass can be calculated as follows:

m=n\times M=0.13091 mol\times 63.01 g/mol=8.25 g

Therefore, 8.25 g of HNO_{3} completely reacts with 4.85 g of Ca(OH)_{2}.

(c) The acid base neutralization reaction is as follows:

H_{2}SO_{4}(aq)+2 KOH (aq)\rightarrow 2H_{2}O(l)+K_{2}SO_{4}(aq)

From the above balanced chemical reaction, 2 mol of KOH completely reacts with 1 mol of  H_{2}SO_{4}. The mass of KOH  is given 4.85 g, convert this into number of moles as follows:

n=\frac{m}{M}

Molar mass of KOH  is 56.1056 g/mol, thus,

n=\frac{4.85 g}{56.1056 g/mol}=0.0864 mol

Thus, 0.0864 mol of KOH reacts with \frac{0.0864 mol}{2}=0.0432 mol of H_{2}SO_{4}

Since. molar mass of H_{2}SO_{4} is 98.079 g/mol, thus, mass can be calculated as follows:

m=n\times M=0.0432 mol\times 98.079 g/mol=4.24 g

Therefore, 4.24 g of KOH completely reacts with 4.85 g of H_{2}SO_{4}.

What is the octet rule? What is it based on?
Nimfa-mama [501]

Answer: The octet rule is a chemical rule of thumb that reflects the observation that main group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.
