Why was it possible to neutralize HCI using NaOH?

Chemistry

6 0
HCl andNaOH are both strong acids/bases and they disassociate pretty much completely. Therefore as the reaction occurs, H+ and OH- form water, while NaCl is formed from chlorine and sodium ions. A neutral solution has a pH of 7 same as water

The melting point of copper is 1084°C. How does the energy of the particles in a certain amount of liquid copper compare to the
ipn [44]
The melting point of the solid form of water, which is ice, is 0°C. When we convert both temperatures to kelvin by adding 273 to each we get the melting point of copper as 1357K and that of ice is 273K. Then, dividing the melting point of copper by the melting point of ice, both in absolute temperature scale. The answer would be 4.97. Thus, the energy of molecules of copper is approximately 5 times compared to that of water.

How many moles of oxygen gas are need to produce 5.53 x 10 moles of water (1)
SIZIF [17.4K]

Answer:

2.765 × × 10³ moles of O₂

Explanation:

The chemical equation to produce water from oxygen and hydrogen is;

2H₂ (g) + O₂ (g) = 2H₂O (l)

From the equation above, we see that;

2 moles of H₂O is produced from 1 mole of O₂

Thus; 5.53 × 10³ moles of H₂O  will require;

(5.53 x 10³ moles of H₂O × 1 mole of O₂)/2 moles of H₂O = 2.765 × × 10³ moles of O₂

An endothermic dissolution process a. absorbs energy as heat and has positive enthalpy of solution. b. releases energy as heat a
Whitepunk [10]

Answer:

a. absorbs energy as heat and has positive enthalpy of solution.

Explanation:

A reaction can either be exothermic or endothermic. An endothermic reaction, as the dissolution described in the question, is that which absorbs heat energy from the surroundings in order to start the reaction.

Because an endothermic reaction makes heat lost from the surroundings, the enthalpy (∆H) of the solution will be positive (+). ∆H is got by finding the difference between the enthalpy of the reactants and products and since the enthalpy of a product in endothermic reaction is more, the enthalpy change (∆T) will be positive.
