A molecule with a single covalent bond is _____. co cl2 co2 n2

Chemistry
2 answers:
Lelechka [254]3 years ago
7 0

Answer:

Cl2

Explanation:

Chemical bonds in general can be classified as ionic and covalent

Ionic bonds are formed by the complete transfer of electrons from one atom to the other while covalent bonds are formed by the mutual sharing of electrons.

1) In CO i.e. carbon monoxide the C and O atoms are connected by 3 covalent bonds

2) In Cl2, the Cl atoms are connected by 1 covalent bond

3) IN CO2, the central C atom is bonded to O atoms by 2 covalent bonds

4) In N2, the N atoms are connected by 3 covalent bonds.

What salt is produced in each of the following neutralization reactions?
Pavlova-9 [17]

1. Salt is KNO₃<span>

<span>This is a </span>strong acid - strong base<span> <span>reaction. </span></span>HNO</span>₃ is the strong acid<span> <span>and </span></span>KOH is the strong base<span>. </span><span>

H</span>⁺<span> in the HNO₃<span> and </span></span>OH⁻<span> <span>of the KOH pair up and make </span></span>H₂O(l)<span>. </span><span>

NO</span>₃⁻<span> <span>and </span></span>K⁺<span> <span>pair up to make </span></span>KNO₃ salt<span>. </span><span>

<span>When writing chemical formulas </span>positive ion comes first<span> <span>and second is negative ion. The charges should be switched. Since </span></span>positive ion has +1 and negative ion has -1<span> <span>after the switching off charges </span>the </span>product should be KNO</span>₃.<span>

Balance equation is </span><span>
HNO</span>₃<span>(aq) + KOH(aq) → H</span>₂O(l) + KNO<span>₃(aq)</span><span>
<span>
2. Salt is Ca(NO</span></span>₃)₂<span>

</span>This is a strong acid - strong base<span> reaction. </span>HNO₃ is the strong acid<span> and </span>Ca(OH)₂ is the strong base<span>. </span><span>
<span>
H</span></span>⁺<span> in the HNO₃ and </span>OH⁻<span> of the Ca(OH)₂ pair up and make </span>H₂O(l)<span>. </span><span>

Ca²⁺ and </span>NO₃⁻<span>  pair up to make </span>Ca(NO₃)₂ salt<span>. </span><span>
<span>
</span><span>Positive ion is </span>Ca²⁺<span> which has </span></span>+2 charge<span> and negative ion is</span> NO₃⁻<span> <span>which has </span></span>-1 charge<span>. From switching the charges </span>Ca²⁺ gets 1<span> <span>while </span></span>NO₃⁻ gets 2.<span> Hence, the salt should be </span>Ca(NO₃)₂.<span>

Balanced equation is 
</span>2HNO₃<span>(aq) + Ca(OH)</span>₂<span>(aq) → 2H</span>₂O(l) + Ca(NO<span>₃)₂(aq)</span><span>
<span>
3. Salt is CaCl</span></span>₂<span>

This is a strong acid - strong base<span> reaction. </span>HCl is the strong acid<span> and </span>Ca(OH)</span>₂ is the strong base<span>. </span><span>
<span>
H</span></span>⁺<span> in the HCl and </span>OH⁻<span> of the Ca(OH)₂ pair up and make </span>H₂O(l)<span>. </span><span>

Ca²⁺ and </span>Cl⁻<span> pair up to make </span>CaCl₂ salt<span>. </span><span>
<span>
</span><span>Positive ion is </span>Ca²⁺ which has </span>+2 charge<span> and negative ion is</span> Cl⁻<span> which has </span>-1 charge<span>. By switching the charges </span>Ca²⁺ gets 1<span> while </span>NO₃⁻ gets 2.<span> Hence, the salt should be </span>CaCl₂.<span>

Balance equation is 
</span><span>2HCl(aq) + Ca(OH)</span>₂<span>(aq) → 2H</span>₂O(l) + CaCl₂<span>(aq)

4. Salt is KCl<span>

</span>This is a strong acid - strong base<span> reaction. </span>HCl is the strong acid<span> and </span>KOH is the strong base<span>. </span>
<span>
H</span></span>⁺<span> in the HCl and </span>OH⁻<span> of the KOH pair up and make </span>H₂O(l)<span>. </span><span>

K</span><span>⁺ and </span>Cl⁻<span> pair up to make </span>KCl salt<span>. </span><span>
<span>
</span><span>Positive ion is K</span></span><span>⁺ which has </span>+1 charge<span> and negative ion is</span> Cl⁻<span> which has </span>-1 charge<span>. By switching the charges </span>K⁺ gets 1<span> and </span>Cl⁻ also gets 1.<span> Hence, the salt should be </span>KCl.<span>

If the p-side has a higher doping concentration, explain how to keep tuning to the same radio channel?
zzz [600]

Answer:

increase in temperature of the intrinsic semiconductor

Explanation:

  • If the p-side has a higher doping concentration, it implies that number of holes (positive ion) increased which is greater than number of electron (negative ion) in the n-side
  • in order to balance the intrinsic concentration, that is to balance the number of holes and electrons which depends on temperature.
  • an increase in the temperature of the intrinsic semiconductor (p-side), increases the number of electron but number of holes remains constant.

A balance in the intrinsic concentration helps in tuning to the same radio channel.
