How much KJ is produced when 7.25g of MgO is formed?
2Mg(s) + O2 = 2MgO(s) + 1200kj
Taking into account the definition of enthalpy of a chemical reaction, 107.94 kJ is produced when 7.25g of MgO is formed.
Enthalpy of a chemical reactionThe enthalpy of a chemical reaction is the energy that is released or absorbed when chemicals are transformed into a chemical reaction at constant pressure.
The enthalpy is an extensive property, that is, it depends on the amount of matter present.
Heat in this caseIn this case, the balanced reaction is:
2 Mg + O₂ → 2 MgO + 1200 kJ
This equation indicates that when 2 moles of Mg reacts with 1 mole of O₂, 2 moles of MgO are formed and 1200 kJ of heat is released.
If 7.25g of MgO is formed and being the molar mass of MgO 40.30 g/mole, the moles of MgO formed is calculated as:
moles of MgO= 7.25 g÷ 40.30 g/mole
moles of MgO= 0.1799 moles
When 0.1799 moles of MgO is formed, then you can apply the following rule of three: if 2 moles of MgO are formed when 1200 kJ of heat is released, 0.1799 moles of MgO are formed when how much heat is released?
heat= (0.1799 moles of MgO× 1200 kJ)÷ 2 moles of MgO
heat= 107.94 kJ
Finally, 107.94 kJ is produced.

What is the pH of the buffer solution?
The buffer solution's pH value is 0.18.
What is buffer?An aqueous solution known as a buffer is composed of a weak acid and its salt (acid buffer) or a weak base and its salt (basic buffer). It is used to prevent pH changes in solutions because, when a small amount of a strong acid or base is added to it, its pH changes very little.
Concentration of CH₃CH₂COOH= 2.00 mol dm⁻³
Volume of CH₃CH₂COOH = 200 cm³ = 200 ml
Concentration of CH₃CH₂COONa = 1.00 mol dm⁻³
Volume of CH₃CH₂COONa = 600 cm³ = 600 ml
Ka for CH₃CH₂COOH = 1.32×10⁻⁵
The following expression can be used to determine the pH of an acidic buffer solution:
pH = pKa + log [salt/acid]
We can determine the salt and acid concentrations by changing the given values in the expression above.
[Salt] = 600×1/100 = 6M
[Acid] = 200×2/100 = 4M

Neon is the tenth element with a total of 10 electrons. In writing the electron configuration for neon the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Ne go in the 2s orbital. The remaining six electrons will go in the 2p orbital.
Explanation:
which of the following would NOT be a strong electrolyte? HCl NaOH KBr HF H2SO4
The compound from the list that will not be a strong electrolyte would be HF.
What are electrolytes?Electrolytes are chemical substances that conduct electricity in molten or aqueous forms.
Substances that conduct electricity in molten or aqueous forms can be grouped into two categories, namely:
Strong electrolytesWeak electrolytesStrong electrolytes completely dissociate into their respective component ions in molten or aqueous forms. For example, HCl completely dissociates in aqueous forms as follows:
[tex]HCl (aq) --- > H^+ (aq) + Cl^- (aq)[/tex]
On the other hand, weak electrolytes only partially ionize into their component ions in molten or aqueous forms. For example, HF will ionize in water only to a small extent because it is a weak acid. Only a few ions are present in the aqueous molten forms.
Thus, considering all the compounds given in the option, the one that would not be a strong electrolyte is HF.
