To solve this we must be knowing each and every concept related to Enthalpy. Therefore, 10,148KJ/mol is the ΔH for formation for the reaction 16CO(g) + 18HO(g) 2CH(l) + 25O(g)
Enthalpy term is basically used in thermodynamics to show the overall energy that a matter have. Mathematically, Enthalpy is directly proportional to specific heat capacity of a substances. Specific heat capacity of a substance is the amount of heat required to raise the temperature by one degree Celsius of one gram of a substance.
The balanced equation for the given chemical reaction can be given as
16CO(g) + 18HO(g) 2CH(l) + 25O(g)
ΔH for formation= 10,148KJ/mol
Therefore, 10,148KJ/mol is the ΔH for formation for the reaction 16CO(g) + 18HO(g) 2CH(l) + 25O(g)

Please answer!! Its really important..
Answer : Lending makes the element as cation (positively charged species) and borrowing makes the element as anion (negatively charged species).
Usually all the metal species donates the electrons and non-metals accepts (borrows) the electrons.
Sodium (Na) donates 1 electron and becomes .
Phosphorus (P) accepts 3 electrons and becomes an anion of phosphorus .
Potassium (K) donates its one electron and gets converted to .
Oxygen (O) accepts 2 electrons and turns as .
Iodine (I) accepts one electron and gets converted into .
Cesium (Cs) donates 1 electron and turns to .
Bromine (Br) accepts 1 electron and turns as .
Sulfur (S) accepts 2 electrons and becomes.
Magnesium (Mg) donates its 2 electrons and gets converted as .
b. covalent bonding
c. metallic bonding
d. ionic bonding
Answer:
The correct answer is D.
Explanation:
Cesium chloride is held together by ionic bonding. This substance is a salt like sodium chloride. It is also soluble in water. When it dissociates, it forms into cesium ions and chloride ions.
Answer:
The correct answer is 8.0 atm.
Hydrocarbons are organic compounds which contain hydrogen, H and carbon, Conly (option B)
Hydrocarbons special class of organic compounds that contains only carbon (C) and hydrogen (H).
Hydrocarbons are classified into:
Generally, hydrocarbons are group into different homologous series. Some of which includes:
All of the above have only carbon and hydrogen in their structural formula.
Thus, with the above information, we can conclude that hydrocarbons contains H and C only (option B)
