one has a 2 at the end
The formula unit for the compound between NO2 and Be would be Be(NO2)2. This is because the charge on Be is 2+, so it requires 2 NO2 ions each with a charge of 1- to balance the charges in the compound.
The compound formed between Co2+ and NO2- ions is cobalt(II) nitrite, with the chemical formula Co(NO2)2. In this compound, the cobalt cation has a +2 charge, and the nitrite anion has a -1 charge, so two nitrite ions are needed to balance the charge of the cobalt cation.
NO2 is a brown gas with a pungent odor and is a stronger oxidizing agent compared to NO, which is colorless and odorless. You can use chemical tests or analytical instruments like gas chromatography or infrared spectroscopy to differentiate between the two gases based on their unique properties.
Determine the molar mass of NO2 using the subscripts in the formula and the atomic weights in grams from the periodic table. 1 mole NO2 = (1 x 14.0067g N) + (2 x 15.9994g O) = 46.0055g NO2 Calculate the moles NO2 by dividing the given mass by the molar mass. 25.5g NO2 x (1mol NO2/46.0055g NO2) = 0.554mol NO2
NO2 is the chemical formula for nitrous oxide.
NO2 plus (NO2+) is a cationic species with a positive charge, while NO2 is a neutral molecule. NO2 is a brown gas at room temperature, whereas NO2+ is a highly reactive and unstable species that is rarely encountered independently.
NO2 is more polar than CO2 due to the presence of a polar N-O bond in NO2 compared to the nonpolar C=O bonds in CO2. The difference in electronegativity between nitrogen and oxygen is larger than that between carbon and oxygen, resulting in a greater polarity in NO2.
Chemical formulas: NO2 is Nitrite NO3 is Nitrate
NO2- has a polar covalent bond due to the difference in electronegativity between nitrogen and oxygen. This creates an unequal sharing of electrons, resulting in a polar molecule.
The formula unit for the compound between NO2 and Be would be Be(NO2)2. This is because the charge on Be is 2+, so it requires 2 NO2 ions each with a charge of 1- to balance the charges in the compound.
The formula for one formula unit of the compound between NO2 and Be will be Be(NO2)2. Beryllium forms a +2 cation and nitrite (NO2-) is a polyatomic ion with a -1 charge, so two nitrite ions are needed to balance the charge of one beryllium ion in the compound.
The correct chemical formula for the reaction between Ca^2+ and NO2^- is Ca(NO2)2. In this reaction, the calcium ion (Ca^2+) combines with two nitrite ions (NO2^-) to form calcium nitrite.
The formula of one formula unit of the compound between NO2 and Be is Be(NO2)2. This is because beryllium has a 2+ charge and nitrite ions have a 1- charge, so two nitrite ions are needed to balance the charge of one beryllium ion.
The compound formed between Co2+ and NO2- ions is cobalt(II) nitrite, with the chemical formula Co(NO2)2. In this compound, the cobalt cation has a +2 charge, and the nitrite anion has a -1 charge, so two nitrite ions are needed to balance the charge of the cobalt cation.
Potassium nitrite, not Potassium nitrate which is KNO3
NO2 is more harmful to the environment than NO2-.
NO2 is the molecular formula for NO2.
