Answer:An atom's positive particles are surrounded by negative matter, so the negative particles are easier to remove.
Explanation:
From our knowledge of the atom, we know that the nucleus lies at the center of the atom. The nucleus is positively charged because it contains the positive particles in the atom
The negative matter (electrons) surround the positive matter (protons) hence it is easier to remove the negative particles compared to the positive particles.
The molecular formula for hyponitrous acid is H2N2O2. and for nitroxyl is HNO.
The chemical compound HNO is also known as nitroxyl (common name) or Azanon (IUPAC name). In the gas phase, it is widely recognized. In the solution phase, the short-lived intermediate nitroxyl can develop. Nitric oxide (NO) is reduced to form the conjugate base, NO, which is isoelectronic with dioxygen.
By oxidizing hydroxylamine with CuO , HgO, and Ag 2 and by oxidizing hydroxylamine with N2O3 in methyl-alcoholic solution, we can create hyponitrous acid.

The overall atom is non-polar because there are two negatively charged sides instead of one positive side and one negative side.
Answer: By performing the flame test
Explanation:
The flame test can be performed by the teacher to visually identify the substance in the solution. The metals give a characteristic color on burning. The heat of the flame causes the excitation of the electrons present in the metal ions this leads to release of energy along with the emission of visible wavelength of light. This visible light can be observed by human eye. For example, the copper produces the blue color in flame, barium gives green flame, and sodium gives yellow flame.
Based on the data provided, the total energy of the reaction is 1066 kJ and the reaction is endothermic
<h3>What is the total energy of a reaction?</h3>
The total energy change of a reaction is the difference between the total bond energy of the reactants and the total bond energy of the products.
- If the total change in bond energy is positive, the reaction is endothermic.
- If the total change in bond energy is negative, the reaction is exothermic.
- The total energy change of a reaction = bond energy of reactants - bond energy of products
Bond energy of reactants = 2000 kJ
Bond energy products = 934 kJ
Total energy of reaction = (2000 - 934) kJ = 1066 kJ
The total energy of the reaction is 1066 kJ and the reaction is endothermic.
