Answer:
Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.
Explanation:
Answer:
Bronze is made of the metals copper and tin.
Explanation:
Bronze is stronger than copper as an outcome of combining that metal with tin or different ores. Bronze is more quickly dissolved and is hence more comfortable to cast. It is also harder than pure metal and considerably extra immune to corrosion.
Pure copper is soft and can be formed into wire or pounded into wanted shapes. If the copper is consequently warmed (tempered), it can be performed soft again. Copper and zinc are blended to create brass, and mixed with tin to produce bronze.
Answer: ΔH°f of gaseous nitrogen monoxide is 148.0 kJ/mol
Explanation:
The balanced chemical reaction is,
The expression for enthalpy change is,
where,
n = number of moles
(as heat of formation of substances in their standard state is zero
Now put all the given values in this expression, we get
Therefore, ΔH°f of gaseous nitrogen monoxide is 148.0 kJ/mol
Answer:
9moles of h20 hndi parin ako sure
The Molarity will increase.
