<span>Multiply the coefficient in front of the formula times the subscript for each element. This gives 36 carbon atoms, 72 hydrogen atoms, and 36 oxygen atoms.</span>
Answer:
Intensive
Explanation:
The electrical conductivity of a wire depends on its composition, not the length of the wire.
Hope this helps! If correct pls mark brainliest :)
A. The number of valence electrons increases as atomic mass increases. == Generally true for the representative elements since atomic mass generally increases with increasing Z.
B. The reactivity of alkali metals increases as atomic mass increases. == True. Atomic mass increases down the column and so does reactivity
C. The reactivity of the halogens increases as atomic mass increases. == False. Reactivity decreases down the column.
D. The number of valence electrons decreases across a period. == False. In general, the number of valence electrons increases across a period, particularly for the representative elements.
Answer:
2m/s^2
Explanation:
Fnet = F2-F1
ma = 8-4
2a = 4
Dividing both sides by 2
a = 2
Therefore (a) thus acceleration is 2m/s^2
