Answer:
The number of moles of salt in one tablespoon is = <u>0.11 mole</u>
<u>Grams </u>cancel each other.
Explanation:
<u>Moles</u> : It is the unit of quantity . It is the mass of the substance present in exactly 12g of C-12.
<u>Moles Calculation:</u>
Given mass = 6.37 gram
Molar mass = 58.5 g/mol
= 0.1088
= 0.11 mole
<u>Units calculation</u>
<u>g ang g cancels each other </u>
moles = moles
<u>Hence unit = gram (g ) cancel each other.</u>
It is endothermic and the ∆H = +393.5 kJ.
Answer:
The amount of thermal energy stored in an object depends on three things.
- The mass of the object.
- The temperature of the object.
- The amount of energy that the particular material stores per degree of temperature.
The answer is True because elements in a compound combine and become an entirely different substance with its own unique properties.
Ionic compounds<span> in solution react </span>faster<span> than molecular </span>compounds<span>. This </span>is <span>because </span>Ionic compounds<span> break apart to form free </span>ions. Therefore, there are no bonds<span> to break </span>so<span> the </span><span>reaction is fast</span>
