Answer:
The water must reach 100 degrees Celsius in order for the water to start boiling. So the boiling point is an intensive property. Likewise, melting point is also an intensive property. Other examples of intensive properties include density , solubility, color, luster, freezing point and malleability.
Percent yield = 70%

</h3>
Percent yield is the comparison of the amount of product obtained from a reaction with the amount you calculated
General formula:
Percent yield = (Actual yield / theoretical yield )x 100%
An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients
Reaction
2H₂ (g) + O₂ (g) → 2H₂O (g)

<u>Answer:</u>
<em>To raise the pH of the solution to 3.10 we have to add 2.34 L of water.</em>
<u>Explanation:</u>
<em>Given that the pH of the solution of HCl in water is 2.5.</em> Here the solution’s pH is changing from 2.5 to 3.10 which means the acidic nature of the solution is decreasing here on dilution. ions contribute to a solution’s acidic nature and contribute to a solution’s basic nature.
The equation connecting the concentration of and pH of a solution is pH=
<em></em>
<em>When the pH is </em>
<em>On dilution the concentration of a solution decreases and volume increases.</em>
<em></em>
<em></em>
<em></em>
<em>Volume of water to be added </em>

<u>Answer:</u> The correct answer is it is an example of combustion.
<u>Explanation:</u>
Combustion reaction is defined as the reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide gas and water molecule.
General equation for these reactions are given as:
Redox reaction is a type of reaction in which reduction and oxidation reaction takes place simultaneously. One substance goes oxidation reaction and another goes reduction reaction.
Combustion reactions are also termed as oxidation reactions because oxygen is getting added to both carbon and hydrogen atoms.
Hence, the correct answer is it is an example of combustion.
should be nonpolar covalent bond i believe, the electronegativity is the same
