What is the frequency of a wave that has 3 waves every five seconds?
Dmitry [639]

Answer:

Frequency, f = 0.6 Hz

Explanation:

We have,

Number of waves passing through a point are 3

Time for which the waves are passing is 5 seconds

It is required to find the frequency of a wave. The frequency of a wave is defined as the no of waves per unit time. So,

f=\dfrac{n}{t}\\\\f=\dfrac{3}{5}\\\\f=0.6\ Hz

So, the frequency of a wave is 0.6 Hz.

Explain why CaCl2 is likely to have properties similar to those of CaBr2
qaws [65]

Answer:

Because both CaCl2 and CaBr2 both contain elements (Chlorine and Bromine) from the same group (group 7)

Explanation:

Elements are placed into different groups in the periodic table. Elements in the same group are those that have the same number of valence electrons in their outermost shell and as a result will behave similar chemically i.e. will react with other elements in the same manner.

Chlorine and Bromine are two elements belonging to group 7 of the periodic table. They are called HALOGENS and they have seven valence electrons in their outermost shell. Hence, when they form a compound with Calcium, a group two element, these compounds (CaCl2 and CaBr2) will possess similar properties because they have elements that are from the same group (halogen group).
