Is nitrogen dioxide acidic or basic?
The actual element nitrogen is neither acidic nor alkaline.
CaN2 what is the oxidation number of N?
In CaN2, nitrogen (N) has an oxidation number of -3. To find this, we know that the overall charge of CaN2 is zero (Ca is +2), so the two nitrogens must have a total charge of -6, making the oxidation number of each nitrogen -3.
What elements make up the troposphere?
Two gases make up the majority of the earth's atmosphere: nitrogen, which comprises 78% of the atmosphere, and oxygen, which accounts for 21%. There are various trace gases make up the remainder.
Is it true that the second most abundant gas in the Earth's atmosphere is carbon dioxide?
No - Nitrogen is the largest quantity of gas in the atmosphere at 79% - followed by Oxygen at 20%. Carbon dioxide and other minute quantities of inert gasses make up just 1% of the total volume.
Calculate the percent yield of chlorine gas in the decomposition of hydrochloric acid if 25.8 grams of hydrochloric acid produces 13.6 grams of chlorine gas?
Percent yield can be calculated using the formula: (actual yield / theoretical yield) x 100. First, determine the theoretical yield of chlorine gas by finding the molar ratio between hydrochloric acid and chlorine gas. Once you have calculated the theoretical yield, plug the values into the formula to find the percent yield.
Nitrogen and hyrogen form ammonia by the reaction N2 plus 3H2 to 2NH3. If 56 grams of nitrogen and 85 grams of hydrogen react to form 62 grams of ammonia. What is the percent yield?
To find the percent yield, first calculate the theoretical yield of ammonia based on the given amounts of nitrogen and hydrogen. Then compare the actual yield (62g) with the theoretical yield to calculate the percent yield using the formula: (actual yield/theoretical yield) x 100%. The percent yield would be the actual mass of ammonia produced (62g) divided by the theoretical yield of ammonia.
How many units of urea are in 1 ton?
Urea is 46-0-0, and ammonium nitrate is 34-0-0. Both of these products contain nothing but nitrogen, but the nitrogen is at different percentages. Urea contains 920 actual pounds of nitrogen per ton, and ammonium nitrate contains 680 actual pounds of nitrogen by ton (2,000 x 46% = 920 and 2,000 x 34% = 680)
Is nitrogen dioxide acidic or basic?
The actual element nitrogen is neither acidic nor alkaline.
What is covalency of nitrogen in N2O5?
wcovalency means the max number of electron an atom can share with others. nitrogen can share 5 but due to the absence of d orbital it can only share 4. therefore the actual covalency in 4.
Oxidation state of nitrogen?
The oxidation states of nitrogen can range from -3 to +5, with common ones being -3, 0, +3, +4, and +5. The actual oxidation state of nitrogen in a compound depends on its overall charge and the electronegativities of the surrounding atoms.
What color is nitrogen fertilizer?
Nitrogen fertilizer typically appears as a white or off-white granule or crystal, often coated with a colorant to indicate its nitrogen content. Common forms include urea, ammonium nitrate, and ammonium sulfate, which are usually colorless or slightly yellowish. However, the actual appearance can vary depending on the specific formulation and any additives used in the product.
How do plants get nitrogen from the atmosphere?
Direct nitrogen fixation is performed by a rather specific kind of organism that probably lived free before the atmosphere began to contain oxygen. Today these are anaerobic bacteria that live in nodules on the roots of plants, particularly the legumes. The actual process is brought about by enzymes called nitrogenases. It is an energy intensive process, requiring a lot of ATP in acid conditions. To fix one molecule of nitrogen requires sixteen ATP molecules and the product is ammonia, which is immediately converted to ammonium ion by acid hydrogen. This is still not available to the plant, but if excreted into the soil other aerobic bacteria convert it to nitrite using oxygen, and then nitrate, and this is available to the plant. Another pathway is to convert the ammonium directly into glutamic acid, which the plant can use directly to generate protein.
What is the real scientific name for nitrogen?
The English word nitrogen (1794) entered the language from the French nitrogène, coined in 1790 by French chemist Jean-Antoine Chaptal (1756–1832), from the French nitre (potassium nitrate, also called saltpeter) and the French suffix -gène, "producing", from the Greek -γενής (-genes, "begotten"). Chaptal's meaning was that nitrogen is the essential part of nitric acid, which in turn was produced from nitre. In earlier times, niter had been confused with Egyptian "natron" (sodium carbonate) – called νίτρον (nitron) in Greek – which, despite the name, contained no nitrate.
What is the solution of 1500 less 20 percent?
1200 Actual calculation is (1500*((100-20)/100)
CaN2 what is the oxidation number of N?
In CaN2, nitrogen (N) has an oxidation number of -3. To find this, we know that the overall charge of CaN2 is zero (Ca is +2), so the two nitrogens must have a total charge of -6, making the oxidation number of each nitrogen -3.
What is the bond angle of nitrogen trifuoride?
Nitrogen trifluoride is a planar molecule. The nitrogen atom is directly bonded with three fluorine atoms on the same plane. According to the VSEPR theory, it has a bond angle of 120 degrees. I think there is confusion with boron trifluoride. The actual measured bond angle of NF3 is 102.50 In VSEPR theory (Valence shell electron pair theory) the number of electron pairs around the nitrogen are counted and there are four. If all of pairs were identical as in methane for instance, then the bond angle would be the tetrahedral angle of 109.5 0 however the lone pair decreases the other angles slightly
HOW DO YOU FERTALIZE AN AVACADO TREE?
Fertilize your young avocado trees with ½ to 1 pound of actual nitrogen per tree per year. You can spread it out over several applications as long as it totals ½ to 1 pound of nitrogen. The other important nutrient for avocado trees is zinc. Ordinary home fertilizer for houseplants will normally work.
