Spring 201s 1s p) Closed Baeek Answer Tnae or False b. In 2003, North Americas(US, Canada, Mexico) per cepita geergy emissions are associated with burning fossil fuels for enorgy with larger amount associsted with land use d. Acid rain is caused by only SO in the atmosphere. e. It is predicted that the likely range of temperature increases in the next century will range from 2.4 to 6.4 f. Impact of energy on environment includes increased damage fom floods storm along the eoasts. g. Carbon dioxide equivalents are a metric measure used to compare the mass emissions of GHG to a common constituent, based on the specific gas\'s dlobal warming potential in unit\'s million tons of COn equivalents. h. The nucleus is composed of positively charged protons and of ncutrons that have i. j. no charge Isotopes are atoms of the same element that contain a different number of neutrons and thus have different weights. Activity coefficients is dependent of the solution\'s ionic strength. 2. Define the following a. Biosorption b. BOD d. Alkalinity e. Biomass

Solution

B- BOD

it ia defined as the amount of oxygen required for decomposition of Biodegradable Organic matter present in the system.

it is measured at standard temprature say 20 degree C

5 day BOD is approximatly 68% of ultimate bod

A Biosorption

It is defined as the ability of biological materials to accumulate heavy metals from wastewater through metabolically mediated or physico-chemical pathways of uptake

Although using biomass in environmental cleanup and this is useful for engineering and scientific purpuse and it provides an economical alternative for removing toxic heavy metals from industrial wastewater and aid in environmental remediation and improvement,

C GWP

Global warming potential is the relative measure of heat that green house gases traped in atmosphere .It compares the amount of heat trapped by a certain mass of the gas in with respect to the amount of heat trapped by a similar mass of carbon dioxide

D ALKINITY

it is defined as the quality of ions in water that will react to neutralise the hydrogen ion.

thus it is a measure of the ability of water to neutralize acids.

Alkalinity is the capacity of water to resist changes in pH that would make the water more acidi

E BIOMASS

it is defined as the maount of living habitant ,organism , organic matter especially plant (that can be converted into fule) which can be  expressed either as the weight of organisms per unit area or as the volume oforganisms per unit volume of habitat called biomass
