<span>During neutralization reaction
Milliequivalent of acid=milliequivalent of base.
Milliequivalent of HCl=0.100*12*1
Milliequivalent of NaOH=M*10*1
So 0.100*12*1=M*10*1
Solve for M.</span>
Answer
a) : = +ve
b) : = -ve
c) : = +ve
d) : = +ve
Explanation:
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
a)
As solid is moving to ions form , randomness increases and thus sign of is positive.
b)
As gaseous reactants are converted to solid products , randomness decreases and thus sign of is negative.
c)
As liquid is changing to gas randomness increases and thus sign of is positive.
d)
As 8 moles of gaseous reactants are converted to 11 moles of gaseous products , randomness increases and thus sign of is positive.
Answer:
An atom becomes anion when it gains or loses electrons. The ions that are formed when an atom loses electrons are positively charged because they have more protons in the nucleus than electrons in the electron cloud.

Madison Boulder is made of fine-grained feldspar and larger quartz crystals that welled up under great pressures from a molten mass deep in the earth over 200 million years ago. Upon cooling, the molten rock hardened. Over the millions of intervening years softer materials on the earth's surface were removed by erosion from wind and water. Not so with the granite of New Hampshire, the Granite State!
As recently as 1835, geologists believed that huge boulders like Madison Boulder isolated in their surroundings had been washed to their present locations by great floods which are said to have occurred in ancient times. Today, it is believed that these large boulders, or "erratics," were moved various distances during the last ice age.
Most authorities trace Madison Boulder to the Whitton or White ledges 12.5 and 4 miles respectively, to the northwest. However, a few maintain that the boulder so closely resembles one of the four types of rock that form Mount Willard in Crawford Notch, twenty-four miles to the nothwest, that the ice sheet must have brought it from there. Madison Boulder lies on "glacial drift," unsorted sediments left by the retreating ice sheet.
Answer:
Some bacteria like <em><u>rhizobium</u></em> and <u><em>blue green algae</em></u> are able to fix nitrogen gas from the atmosphere to enrich the soil with nitrogen compounds and increase its fertility. The nitrogen-fixing bacteria and blue green algae are called <u><em>biological nitrogen fixers.</em></u>
