Im pretty sure it weight because when we are on different plants with a different amount of gravitational pull our weight changes
hope this helps :)
1 mole of
is 180 grams. (Molar mass).
18 is
of 180 , so it means 18 grams of
is
moles
To find a molecule's molar mass, you should multiply each atom's number with their atomic mass, in the molecule and add them I mean, there are 6 Carbon atoms, 12 Hydrogen atoms and 6 Oxygen atoms. So,
Atomic mass of Carbon is approximately, 12 amu (atomic mass unit), Hydrogen's is approximately, 1 and Oxygen's is approximately, 16. So :
Most likely White or another color that appears "bright" to us, such as gold, silver, yellow, pink, or sometimes green. Hope it helped!
The standard enthalpy of reaction should be negative.
<h3>What is enthalpy?</h3>
A thermodynamic quantity equivalent to the total heat content of a system. It is equal to the internal energy of the system plus the product of pressure and volume.
Inside the heat pack are two chemicals that get mixed when you smush them together. As they mix, some weak bonds are broken, which takes a little bit of energy. But new, stronger bonds form which release energy. Releasing that energy causes the surroundings to heat up.
Hence, option B is correct.
