I would love to help you out. What are the Options?
The bond angle of bonds in an octahedral molecule is 90 degrees
Answer:
The correct option is the A
Explanation:
Like oxygen is more electronegative than hydrogen, it attracts electrons stronger than hydrogen. Therefore the two covalent bonds are polar.
The option b is incorrect because if oxygen and hydrogen had similar electronegativities, they would form no-polar bonds.
The option c is incorrect because oxygen is more electronegative than hydrogen (you can check that in a periodic table).
The options d and e are incorrect because the molecular size or hydrophilic don't influence the type bond.
Explanation:
<u>Electrical energy:</u> Kinetic energy caused by moving electrons
<em>Example of energy: lighting</em>
<u>Chemical energy:</u> Energy stored in matter
<em>Example of energy: natural gas</em>
<u>Light energy:</u> a kind of kinetic energy that moves in waves and can be seen
<em>Example of energy: stars</em>
<u>Mechanical energy:</u> Is the sum of an object's kinetic energy and potential energy
<em>Example of energy: dart guns</em>
Answer:
All isotopes of an element have the same number of protons and electrons, which means they exhibit the same chemistry. The isotopes of an element differ only in their atomic mass, which is given by the mass number (A), the sum of the numbers of protons and neutrons.
