Thermal decomposition of common salt. Explain.​

Answer»

Thermal decomposition, or thermolysis, is a chemical decomposition caused by heat. The decomposition temperature of a substance is the temperature at which the substance chemically DECOMPOSES. The reaction is USUALLY endothermic as heat is required to break chemical bonds in the compound undergoing decomposition. If decomposition is sufficiently exothermic, a positive FEEDBACK loop is created PRODUCING thermal RUNAWAY and possibly an explosion or other chemical reaction.I HOPE THAT'S THE RIGHT ANSWER

Differentiate between elemants and compounds​

Answer»

difference between elements and compoundsElements are formed with the same types of atoms. For example, we are considering oxygen (O₂). Oxygen is formed with two oxygen (O) atoms of the same kind, ATOMIC number and properties. Compounds are constructed with more than one type of ATOM. For example, we are taking water (H₂O). Water is formed with two HYDROGEN (H) and one Oxygen (O) atoms. Water is constructed by the covalent bond between H and O atoms. That is why water has VARIOUS properties.

Why do the electron of an atom not jump into the nucleus​

Answer»

An electron in an atom SPREADS out ACCORDING to its energy. The STATES with more energy are more spread out. All electron states overlap with the nucleus, so the concept of an electron "falling into" or "entering" the nucleus does not really make sense. Electrons are always partially in the nucleus.itZz ANANYA ❤️

In the field of chemistry, a mole is defined as the amount of a substance that contains exactly 6.02214076 * 10 23 ‘elementary entities’ of the given substance. The number 6.02214076*10 23 is popularly known as the Avogadro constant and is often denoted by the symbol ‘N A ’. The elementary entities that can be represented in moles can be atoms, molecules, monoatomic/polyatomic ions, and other particles (such as electrons). For example, one mole of a pure carbon-12 ( 12 C) sample will have a mass of exactly 12 grams and will contain 6.02214076*10 23 (N A ) number of 12 C atoms. The number of moles of a substance in a given pure sample can be represented by the following formula: n = N/N A Where n is the number of moles of the substance (or elementary entity), N is the total number of elementary entities in the sample, and N A is the Avogadro constant. The word “mole” was introduced around the year 1896 by the German chemist Wilhelm Ostwald, who derived the term from the Latin word moles meaning a ‘heap’ or ‘pile. (i) How many moles of iron are present in a pure sample weighing 558.45 grams? a) 10 moles b) 20 moles c) 30 moles d) 5 moles (ii) How many grams of carbon can be found in 1 mole of carbon dioxide? a) 1 g b) 5g c) 12 g d) 14 g

Answer»

Explanation:One MOLE (mol) contains exactly 6.02214076 × 1023 elementary entities. This number is the FIXED NUMERICAL value of the Avogadro constant, NA, when EXPRESSED in the unit mol−1 and is called the Avogadro number. The amount of substance, symbol n, of a system is a measure of the number of specified elementary entities.

As a responsible citizen, we should remember the 5R principle. Comment on this statement

Answer»

The 5R principle of waste management is reduce, reuse, recycle, recover and RESIDUAL management. In all biological waste treatment processes some surplus sludge is produced. The objective of residual management is reduction of water content, stabilization of sludge solids, reduction in sludge solids VOLUME. Recycling is the process of collecting and processing materials that would otherwise be THROWN away as trash and turning them into NEW products. Recycling can benefit your community and the environment.

Which of the following pairs of elements would have a more negative electron gain enthalpy? (i) O or F (ii)F or Cl (iii) O or S. Give reason to support your answer.​

Answer»

O or F.Explanation: ELECTRON gain enthalpy of F is much more negative than that of O. This is because as we from O to F, the atomic size decreases and nuclear CHARGE increases, thereby increase the attraction of the nucleus for the incoming electron and hence electron gain enthalpy BECOMES more negative.

when 10 ml of water is mixed with 30 ml of ethenol the total volume was found to be not to 40 ml . which type of decision is exhibited by it and why​

Answer»

<30mlUpon mixing 20 mL ethanol to 10 mL WATER, the net volume is less than 30 mL. This is because of extensive hydrogen bonding among water molecules that gives empty space between the molecule. but in the presence of ethanol some of these bonding breaks and thereby REDUCES the net volume. The ethanol molecules goes into those voids resulting in lower volume.Explanation:HOPED my answer HELPED you and mark me as BRAINLIEST
