False

In case of all polar molecule the amount of inter molecular forces (such as cohesion, adhesion etc.) is much smaller than intramolecular forces (such as dipole –dipole interactions, Hydrogen bonding etc.)

Due to this reason a polar molecule form a dipole –dipole structure due to which the charges are unevenly distributed on different parts of  neutral molecule. The electrons are more strongly oriented towards oxygen atom and thus it gets negatively charged and hydrogen gets positively charged. A polar molecule attract another polar molecule either through Hydrogen bonding or through dipolar attraction between them.  

For example dissolution of HCl in water is a polar -polar molecule interaction.

Describe the steps of hemostasis.
makkiz [27]

Answer:

Hemostasis incorporates three stages that happen in a fast grouping: (1) vascular fit, or vasoconstriction, a brief and serious compression of veins; (2) arrangement of a platelet fitting; and (3) blood thickening or coagulation, which fortifies the platelet plug with fibrin work that goes about as a paste to hold the coagulation.

Which of the following is maintained across the terminals of a battery?
astraxan [27]

Answer:

Option D, both A and B

Explanation:

The potential difference is created across a battery (between its two terminal –one positive and the other one negative) when work is done to move a charge from one point to another. This potential difference is measured in volts. 1 volt is the potential difference between two points when one joule of potential energy is spent to move a charge of one coulomb from one point to the other.  

Voltage drop across a circuit is the amount of electric current lost due to resistance/ impedance with in the cables of the circuit.  

Hence, both potential difference and voltage drop occurs across the circuit,  

Option D is correct.

sergiy2304 [10]

Answer:

he eye is made up of three coats, which enclose the optically clear aqueous humour, lens, and vitreous body. The outermost coat consists of the cornea and the sclera; the middle coat contains the main blood supply to the eye and consists, from the back forward, of the choroid, the ciliary body, and the iris.

Explanation: Right up there.

Water is composed of one oxygen atom covalently boded to two hydrogen atoms. Select all of the
mafiozo [28]

Answer:

F: The oxygen atom has a greater attraction for the electrons in the surrounding covalent bonds than the

hydrogen atoms.​

Explanation:

Between hydrogen and oxygen atoms exist a covalent bond. Oxygen is more electronegative than hydrogen atom hence its ability to get attracted to itself more electrons than hydrogen.
