Mass is a coherent, typical large body of matter with no definite shape. Another way to describe matter is a very heavy or large object.Matter can also be described with length. This is how i know matter is a very large length or weight. (Hope this helped) :)
Radio waves infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.
Becasue KE= 1/2 mv squared
KE= 1/2 (100) 12.5 sqaured
50 156.25 =
7812.5 < is your answer
Hopefully that makes sense and i did the math right....
<h3>Answer : 2C + 3H2 -> C2H6</h3>
<h3>Step and explanation</h3>
Condition : graphite + hydrogen gas
Chemical formula : C + H2
Reaction formula :
C + H2 -> C2H6
#First, you see the number of atom
•Product
C = 1
H = 2
•Reactant
C = 2
H = 6
<em>#</em><em>N</em><em>o</em><em>t</em><em>e</em><em> </em><em>that</em><em>,</em><em> </em><em>in</em><em> </em><em>a</em><em> </em><em>chemical</em><em> </em><em>reaction</em><em> </em><em>both</em><em> </em><em>number</em><em> </em><em>of</em><em> </em><em>each</em><em> </em><em>atom</em><em> </em><em>in</em><em> </em><em>product</em><em> </em><em>must</em><em> </em><em>be</em><em> </em><em>equal</em><em> </em><em>in</em><em> </em><em>reactant</em><em> </em><em>so</em><em>,</em><em> </em><em>you</em><em> </em><em>think</em><em> </em><em>what</em><em> </em><em>number</em><em> </em><em>you</em><em> </em><em>need</em><em> </em><em>to</em><em> </em><em>put</em><em> </em><em>Infront</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>chemical</em><em> </em><em>formula</em><em> </em><em>so</em><em> </em><em>that</em><em> </em><em>the</em><em> </em><em>number</em><em> </em><em>of</em><em> </em><em>atom</em><em> </em><em>equal</em>
2C + 3H2 -> C2H6
#Now check again
•Product
C = 2
H = 6
•Reactant
C = 2
H6
#Now, its equal. The bold one is the balance chemical reaction
<h3>Note (just incase u dont know)</h3>
Reactant -> product (the thing you get after reaction)
