Godly aspect Psalm 63: Prayer is the breath of our relationship of God. The absence of prayer shows that we are spiritually dead. I don’t mean just saying prayers that are not spawned from the heart‚ of course. Jesus said empty prayers amounted to only religious ceremony. One can dress up a dead body but there sure is a difference between that corpse and a living person even if he is sick. What do you think of when prayer is mentioned? This is a good question. Your answers reveal a lot about your

cat cracker. Catalysts used for cracking alkanes are inorganic compounds called zeolites crystalline compounds of Al‚ Si‚ and O with some metal ions. Zeolites are effective as catalysts because they have a very large surface area per unit mass. Mixtures of alkanes can also be cracked by thermal or steam cracking. ================================ Properties of Alkanes and Alkenes Alkenes have similar physical properties to the corresponding alkanes. They are both non-polar molecules with weak

Water is never ’pure’ in a chemical sense. It contains various kinds of impurities such as dust particles‚ dissolved gases‚ dissolved minerals‚ microscopic paints and animals‚ suspended impurities and bacteria. These are natural impurities derived from the atmosphere‚ catchments area and soil. Besides this‚ there are various other reasons by which water i9 polluted. The upland surface water derives its impurities from the catchments area‚ the sources being human habitations and animal keeping

Organic chemistry is the study of essentially all substances containing carbon. Organic compounds that contain only carbon and hydrogen are called hydrocarbons. The simplest hydrocarbons are the alkanes which contain only single covalent bonds. Methane is the simplest alkane. It is also the major component of natural gas. Methane contains only 1 carbon in the molecular formula and the structural formula. There is ethane which is 2 carbons‚ propane that is 3‚ butane which is 4‚ pentane which is 5
Premium Hydrogen Atom Chemistry
Methane is a chemical compound with the chemical formula CH4. It is the simplest alkane‚ and the principal component of natural gas. Methane’s bond angles are 109.5 degrees. Burning methane in the presence of oxygen produces carbon dioxide and water. The relative abundance of methane makes it an attractive fuel. However‚ because it is a gas at normal temperature and pressure‚ methane is difficult to transport from its source. It is generally transported in bulk by pipeline in its natural gas form

Saturated hydrocarbons are characterized by single bonds between adjacent carbon atoms. Saturated hydrocarbons are alkanes and cycloalkanes‚ this compounds are relatively inert and do not react with common laboratory reagents. Alkanes do‚ however react with oxygen‚ halogens and other substances under control conditions. All members of alkane series have the general chemical formula CnHn-1. Alkanes are insoluble in water; other physical properties vary with molecular weight. Members C1 to C4 are gasses at

the asymmetric carbon atoms in the molecule shown below (prostacyclin). (b) Based on the number of asymmetric carbons‚ how many stereoisomers of prostacyclin are possible? 5. Hydrogenation of an alkene will yield an alkane. The alkane formed by hydrogenation of (S)-4-methyl-1-hexene (I) is optically active‚ while the one formed by hydrogenation of (S)-3-methyl-1-pentene (II) is not. Explain. I II 6.

Lab #24- Preparation 4-Methylcyclohexene Introduction: The goals in this lab were to have a reaction occur with 4-methylcyclohexanol and an acid catalyst to form our product of 4-methylcyclohexene via an E1 reaction. This reaction is accomplished by removing the –OH group on 4-methylcyclohexanol via dehydration and to have a double bond form via a loss of a hydrogen on a β-Carbon. Many techniques and skills were developed in this lab. Among them were dehydration‚ isolation‚ drying
