Question 7 options:
Their speeds are the same.
the object with the greater speed has greater kinetic energy
the object greater speed has the lower kinetic energy
the object with the smaller mass has the greater kinetic energy
Answer: Option (B) is the correct answer.
Explanation:
Kinetic energy is the energy due to the motion of an object.
Mathematically, K.E =
where m = mass
v = velocity
Therefore, an object whose velocity is more will have more kinetic energy.
Thus, we can conclude that out of the given options, the object with the greater speed has greater kinetic energy is true about their kinetic energy.
1) C4H8O2
2) C4H12O4
3) C2H10O2
A) CH3O
B) CH5O
C) C2H4O
Answer:
1) C4H8O2 = C2H4O
2) C4H12O4 = CH3O
3) C2H10O2 = CH5O
Explanation:
Answer:
C₄H₈O₂ = C₂H₄O
C₄H₁₂O₄ = CH₃O
C₂H₁₀O₂ = CH₅O
Explanation:
1) C₄H₈O₂ = C₂H₄O
The smallest subscript is 2. So dividing each subscript by 2 we get,
C₄/₂H₈/₂O₂/₂ = C₂H₄O
2) C₄H₁₂O₄ = CH₃O
The smallest subscript is 4. So dividing each subscript by 4 we get,
C₄/₄H₁₂/₄O₄/₄ = CH₃O
3) C₂H₁₀O₂ = CH₅O
The smallest subscript is 2. So dividing each subscript by 2 we get,
C₂/₂H₁₀/₂O₂/₂ = CH₅O
a. K
d. Ci
b. Ca
c. S e. Ba f. Br
Answer:
The ion is written in the attached file
Explanation:
The most typical ions formed by K, Ca, and S are K+, Ca2+, and S2-, respectively.
The symbol of the ion most typically formed by each of the elements can be determined by looking at their positions on the periodic table and considering their electron configuration.
