As the temperature of a solution increases,what happens to its molarity? Explain
HACTEHA [7]
Hey :)

molarity<span> is affected by </span>temperature<span> because morality is simply a measure on the volume of a particular </span>solution<span>, and the volume of a substance will be negatively or positively affected by changes in </span>temperature. In theory, volume will increase<span> when </span>temperature increases<span>, a reciprocal effect of </span><span>molarity</span>

Methane gas and oxygen gas react to form water vapor and carbon dioxide gas. What volume of carbon dioxide would be produced by
Bas_tet [7]

Answer:

V_{CO_2}=9.23m^3

Explanation:

Hello,

In this case, the undergoing chemical reaction is:

CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(g)

Now, as the stoichiometrical factors are in terms of mole but no information about neither the temperature nor the pressure is given, by means of the Avogadro's law, one could perform the stoichiometric calculations with the given volume as both the pressure and temperature remain the same, that is:

V_{CO_2}=9.23m^3CH_4*\frac{1m^3CO_2}{1m^3CH_4} \\\\V_{CO_2}=9.23m^3

Such 1:1 volume relationship equals the 1:1 molar relationship given in the chemical reaction in terms of their stoichiometric coefficients, therefore, the yielded volume of carbon dioxide is also 9.23m³

Best regards.

A calorimeter contains 500 g of water at 25°C.....

the temperature of the water inside the calorimeter is 39.4°C.....

The specific heat of water is 4.18 J/g-°C.

energy needed to heat the water = specific heat * mass * temp difference

= 4.18 J/g-°C * 500 g * (39.4°C - 25°C)

= 4.18*500*14.4

= 30096J

or approx. 30kJ
