Answer:
Inspect the Bunsen burner and gas tubing for damage.
Explanation:
Gas tubes must be attached tighly to the Bunsen burner so that none of the gases would spread and cause fire.
I believe the answer is C, n = 3, l = 3, m = 3. The magnetic quantum number, or
<span>ml</span>, can only take values that range from <span>−l</span> to <span>+l</span>, as you can see in the table above.
For option C), the angular momentum quantum number of equal to ++2<span>, which means that <span>ml</span> can have a maximum value of </span>+2<span>. Since it is given as having a value of </span>+3**, this set of quantum numbers is not a valid one.
The other three sets are valid and can correctly describe an electron.
The element which can not loose electron easily and having electronagtive character is called non-metal it has following property-
1. it can not conduct heat and electricity
2. it is netiher ductile not malleable
3. it is not lsuturous and also not sonorous
<h2>Answer:</h2>
The correct answer is option B which is fusion occurs in the sun.
<h3>Explanation:</h3>
- Fusion in nuclear physics is an reaction in which two or more nuclei fuse to form another atom and due to mass conservation they also release energy.
- This reaction is common in sun and provides energy to sun.
- In sun two hydrogen atoms fuse to for a helium nuclei and giving some amount of energy.
- In sun there are 620 million metric tons of hydrogen fuse together each second.
