The change in enthalpy that accompanies the formation of a compound from its elements?
The energy change that happens when a substance forms from its elements (APEX)
Equation for the heat of formation of carbon disulphide?
The heat of formation (∆Hf) of carbon disulfide (CS2) can be calculated using the standard enthalpies of formation of its constituent elements as follows: ∆Hf (CS2) = ∆Hf(C) + 2∆Hf(S) − ∆Hf(CS2). The standard enthalpies of formation for carbon (C) and sulfur (S) are known values and can be used in the calculation.
What is the product if acetone is heated with con H2SO4?
The product of acetone heating with concentrated H2SO4 is usually the formation of a ketone known as mesityl oxide through a dehydration reaction.
When two elements chemically react the mass of the product is?
When two elements chemically react, the mass of the product is equal to the sum of the two masses of the two elements.
What is the product when C5H10Br2 reacts with NaNH2 in liquid ammonia?
The reaction between C5H10Br2 and NaNH2 in liquid ammonia results in the formation of a diene compound known as 1,5-hexadiene. The NaNH2 acts as a strong base and abstracts a proton from the dihalide compound, leading to the formation of the diene product.
What is a uniting of a sperm cell with an egg cell?
The uniting is known as fertilisation of the egg by the sperm.

Would you expect bond formation to be an energy-releasing process or an energy-absorbing process?
Bond formation is a energy releasing process that means exothermic process.you can calculate these energy by knowing enthalpy change .If energy stored in the product is less then the energy stored in the reactant ,the process is known as exothermic whereas if energy stored in the product is more then the energy stored in the reactant ,the process is known as endothermic.
Has there ever been a meteorite discovered on earth made up of metals that are not found on the periodic table of elements?
No, all elements present in meteorites are found on the periodic table of elements. The formation of meteorites is linked to the same materials that make up the Earth and other celestial bodies, so they are composed of known elements.
What is the formation of deserts known as?
the formation is called desertification)
