A typical person has an average heart rate of 75.0 beats/min. Calculate the following a)How many beats does she have in 7.0 year
2 answers:
Answer:
a) Beats in 7.0 years =
b) Beats in 7.000 yrs=
Explanation:
Step 1
Calculation of no. of min. in 7 year
Days in a year = 365
Hrs in a day = 24
Min. in a 1 hr = 60
Min. in a day = 60 × 24
Min. in a year = 60 × 24 × 365
Min. in 7 years
= 60 × 24 × 365 × 7
= 3679200 min.
a) Beats in 7.0 years
Heart rate = 75.0 beats/min.
Beats in 7.0 yrs
= 75.0 × 3679200
= 275940000 beats
No. of significant figure = 2
Answer has to be reported in 2 significant digits.
Beats in 7.0 years =
a) Beats in 7.000 years
Beats in 7.000 yrs = 275940000 beats
No. of significant figure in 7.000 = 4
Answer has to be reported in 4 significant figures
So, no. of beats in 7.000 yrs=

Answer:
a. the maximum number of σ bonds that the atom can form is 4
b. the maximum number of p-p bonds that the atom can form is 2
Explanation:
Hybridization is the mixing of at least two nonequivalent orbitals, in this case, we have the mixing of one <em>s, 3 p </em> and <em> 2 d </em> orbitals. In hybridization the number of hybrid orbitals generated is equal to the number of pure atomic orbital, so we have 6 hybrid orbital.
The shape of this hybrid orbital is octahedral (look the attached image) , it has 4 orbital located in the plane and 2 orbital perpendicular to it.
This shape allows the formation of maximum 4 σ bond, because σ bonds are formed by orbitals overlapping end to end.
And maximum 2 p-p bonds, because p-p bonds are formed by sideways overlapping orbitals. The atom can form one with each one of the orbitals located perpendicular to the plane.
