Answer:
Water's high heat of vaporization allows dogs to cool themselves by panting.
Explanation:
Vaporization or Evaporation is the process in which the substance is converted into gas (vapors). This is an endothermic reaction and requires energy to be carried out. In dogs this phenomenon is being carried out in order to cool the body.
As the water molecules are evaporated it results in the removal of highly energetic molecules leaving a low energy molecules behind. Hence, cooling is achieved.
Answer:
We assume you are converting between moles CaCl2 and gram. You can view more details on each measurement unit: molecular weight of CaCl2 or grams This compound is also known as Calcium Chloride. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles CaCl2, or 110.984 grams.
34g C * ( 1 mol / 12.0107 ) * ( 1 mol H2 / 1 mol C ) * ( <span>2.01588 g / 1 mol H2 ) = 5.70657164028741 g H2 = 5.7 g H2
Convert grams of C to moles of C using the given amount of grams and the molar mass ( 12.0107 g/mol ).
Gather the mole ratio from the coefficients in the balanced equation and multiply by the ratio.
Convert moles of H2 to grams of H2 </span> using the given amount of grams and the molar mass ( 2.01588 g/mol )<span>.
