Answer:
Metals conduct heat and reduce the kinetic energy within the components that need to remain cool
Answer: A. need the same number of electrons to fill their valence shells
B. have the same number of valence electrons
Explanation:
Elements are distributed in groups and periods in a periodic table.
Elements that belong to same groups will show similar chemical properties because they have same number of valence electrons.
Example: Flourine, chlorine and bromine are elements which belong to Group 17. They have 9, 17 and 35 electrons respectively and contain 7 valence electrons each and need one electron to complete their octet.
The chemical reactivity of elements is governed by the valence electrons present in the element.
Answer:
Un automóvil deportivo de 921 kg se mueve hacia la derecha con una rapidez de 29.0 m / s.
Explanation:
Answer:
Part a)
charge through the battery is
Part b)
Maximum current is
i = 386 A
Explanation:
Part a)
As we know that the rating of battery is given as
here we also know that the charge given by the battery is same as the capacity of the battery
so we will have
Part b)
Now we know that current in the wire is given by
now plug in all values in it
