Ethers have a tetrahedral geometry i.e. oxygen is sp

hybridized. The C−O−C bond angle is 110
o
. Because of the greater electronegativity of O than C, the C−O bonds are slightly polar & are inclined to each other at an angle of 110
o
, resulting in a net dipole moment. This bond angle greater than that of tetrahedral bond angle of 109

′
. This is due to the fact that internal repulsion by the hydrocarbon part is greater than the external repulsion of the lone pair of oxygen.
B- ammonia. ammonia has a pH level of about 11, and anything higher than 7 is more basic and anything less than 7 is more acidic. 7 is considered neutral.
The type of cell that one will likely inject is OSTEOBLAST CELLS. Osteoblasts are cells that make bone. They do this by producing a matrix which becomes mineralized leading to increase in the bone mass. Injecting this type of cell will stimulates rapid healing of broken bones.
Answer:
Litmus paper is one type of acid-base indicator. The paper is imbued with dye derived from lichens that change color in response to the presence of an acid or base. ... Red paper is used to detect alkaline pH and will turn a shade of blue in the presence of a basic solution.
They will continue moving because an object in motion will stay in motion until acted upon by a new force. I believe this is Newton's Law of Motion.
