Missing question:
a) strong base and its conjugate acid.
b) weak base and its conjugate acid.
c) strong acid and strong base.
d) weak acid and its conjugate base.
e) weak acid only.
f) weak base only.
g) strong acid and its conjugate base.
Answers are:
b) weak base and its conjugate acid. For example weak base ammonia (NH₃) and its conjugate acid ammonium ion (NH₄⁺).
d) weak acid and its conjugate base. For example weak acetic acid (CH₃COOH) and its conjugate base CH₃COO⁻.
Buffer solution changes pH very little when a small amount of strong acid or base<span> is added to solution.</span>
a) Gas particles have most of their mass concentrated in the nucleus of the atom.
b) The moving particles undergo perfectly elastic collisions with the walls of the container.
c) The forces of attraction and repulsion between the particles are insignificant.
d) The average kinetic energy of the particles is directly proportional to the absolute temperature.
e) All of the above are postulates of the kinetic molecular theory.
Gas particles have most of their mass concentrated in the nucleus of the atom.
Answer: Option A.
<u>Explanation:</u>
Kinetic Molecular Theory expresses that gas particles are in consistent movement and show flawlessly versatile crashes. Motor Molecular Theory can be utilized to clarify both Charles' and Boyle's Laws. The normal active vitality of an assortment of gas particles is straightforwardly corresponding to total temperature as it were.
The kinetic theory of gases is a significantly critical, however straightforward model of the thermodynamic conduct of gases with which numerous important ideas of thermodynamics were built up.
Okay so i think the answer to this is.
weight=mg
m=0.000100 g=9.80
so weight= 0.00980 kgm/s2
Hopefully thats correct (i am horrible at math)
True, Crude oil is a type of liquid thereofre can flow through the pourus layer but seeming how impermeable means to not allow fluid to pass it would only make sense that the fluid is trapped between the two.
