Why do some elements form double and triple bonds during bonding
jekas [21]

Explanation:

Elements need a total of eight electrons to gain stability and look like a noble gas. So, they sometimes need sharing of two, four or even six electrons to complete their octate. So, they form double and triple covalent bonds. One more  the reason is the  interaction between the p orbitals of the combining atoms. for example  A double bond, as in ethene H2C=CH2, arises from one combination of the s orbitals and one combination of the p_y orbitals.

What is the energy of a microwave photon that has a frequency of 9.86 x 1012 Hz?
BlackZzzverrR [31]

Answer:

6.533 × 10^-21J

Explanation:

The energy of the microwave photon can be calculated using:

E = hf

Where;

E = energy of photon (J)

h = Planck's constant (6.626 × 10^-34 J/s)

f = frequency (9.86 x 10^12 Hz)

Hence, E = hf

E = 6.626 × 10^-34 × 9.86 x 10^12

E = 65.33 × 10^(-34 + 12)

E = 65.33 × 10^(-22)

E = 6.533 × 10^-21J

The energy of the microwave photon is

6.533 × 10^-21J

Three different samples were on different types of balance for each sample. The three were found to weigh 0.1568934 ko. 1.215 mg
Dmitriy789 [7]

Answer:

Option d. 2615.0g

Explanation:

Let M1, M2, and M3 represent the masses of the three different samples

M1 = 0.1568934 kg = 156.8934g

M2 = 1.215mg = 1.215x10^-3 = 0.001215g

M3 = 2458.1g

Total Mass = M1 + M2 + M3

Total Mass = 156.8934 + 0.001215 + 2458.1

Total Mass = 2614.994651g

Total Mass = 2615.0g
