Answer:

Candles produce light by releasing heat. A CANDLE flame consists of three zones. Each zone has different temperatures and colors.

The first zone is called the Outer zone

The second zone is called the Middle zone

The third zone is called the Inner zone

The outer zone is blue in COLOR, due to complete combustion,. This zone is the hottest zone.

The middle one is in yellow color, which is the BRIGHT part of the flame. It is moderately HOT and PARTIAL combustion of fuel takes place.

The least hot region of the flame is innermost zone. This inner zone is black in color due to the presence of unburnt wax vapors.

Answer:

Explanation:

Copper(II) acetate, also referred to as cupric acetate, is the chemical compound with the formula Cu(OAc)2 where AcO− is acetate (CH

3CO−

2). The hydrated derivative, Cu2(OAc)4(H2O)2, which contains ONE molecule of water for each copper atom, is available commercially. ANHYDROUS copper(II) acetate is a dark GREEN crystalline solid, whereas Cu2(OAc)4(H2O)2 is more bluish-green. Since ANCIENT times, copper acetates of some form have been used as FUNGICIDES and green pigments. Today, copper acetates are used as reagents for the synthesis of various inorganic and organic compounds.[4] Copper acetate, like all copper compounds, emits a blue-green glow in a flame. The mineral hoganite is a naturally occurring form of copper(II) acetate.[5][6] A related mineral, also containing calcium, is paceite.[6] Both are very rare.[7][8]

ANSWER:

POTASSIUM ACETATE is the CORRECT answer

Initially, the venom causes a burning sensation, swelling, and pain at the sting site. HOWEVER, sting sites can develop into pustules (pus-filled BLISTERS) that can linger for a couple of WEEKS. The ant venom causes localized cell DEATH, and the pustules are the result of our immune SYSTEMS cleaning up the cell debris.

Answer:

The LATENT heat of VAPORIZATION of water is 22.5 × 105 joules per kilogram (or 22.5 × 105 j/kg). Hence it MEANS that 22.5 × 10 5 J of heat is required to change 1 Kg of water (at its BOILING POINT, 100°C) into steam at the same temperature of 100°C.

Answer:

When salt is added, it makes it HARDER for the water MOLECULES to escape from the pot and enter the gas phase, which happens when water boils, Giddings said. This gives salt water a higher boiling point, she said. . "The temperature of saltwater will get hotter faster than that of PURE water,"

Answer:

OXIDATION reaction is a chemical reaction in which oxygen is added to or hydrogen is removed from an element, molecule or a compound.

The term oxidation was originally used to describe reactions in which an element COMBINES with oxygen.

Example: The reaction between magnesium metal and oxygen to form magnesium oxide involves the oxidation of magnesium. The iron metal is oxidized to form the iron oxide known as rust. Meanwhile, oxygen is reduced.

Oxidation reactions are exothermic.

It GIVES net energy to its surroundings. That is, the energy NEEDED to INITIATE the reaction is less than the energy released. When the medium in which the reaction is taking place gains heat, the reaction is exothermic.

Answer:

Copper metal when exposed to air turns green in colour due to corrosion. When copper vessel is exposed to air in rainy SEASON, the metal reacts with gases and MOISTURE and atmospheric gases to FORM a mixture of copper CARBONATE and copper HYDROXIDE. This gives a green colour to the surface of copper metal.

Answer:

Potassium metal REACTS with WATER to give potassium HYDROXIDE and HYDROGEN gas. Write balanced chemical equation for this REACTION.

NH4NO3

Ammonium nitrate/Formula

By using the criss cross method,the -1 CHARGE of nitrate ION is shifted to ammonium ion and +1 charge of ammonium ion is shifted to nitrate ion. In this way, the FINAL formula NH4NO3 is FORMED for the ammonium nitrate. (Because, +1 charge or -1 charge is omitted in the final chemical formula.)

⠀

Answer:

By using the criss cross method,the -1 CHARGE of nitrate ion is SHIFTED to ammonium ion and +1 charge of ammonium ion is shifted to nitrate ion. In this way, the final formula NH4NO3 is formed for the ammonium nitrate. (Because, +1 charge or -1 charge is OMITTED in the final chemical formula.)
