Answer:
covalent bonding, hydrogen bonding
Explanation:
<u>The molecular formula of water is
in which the two hydrogen atoms are connected to the oxygen atom via covalent bonds which means that the electrons are shared in the bond.</u>
Hydrogen bonding is a special type of the dipole-dipole interaction and it occurs between hydrogen atom that is bonded to highly electronegative atom which is either fluorine, oxygen or nitrogen atom.
Partially positive end of the hydrogen atom is attracted to partially negative end of these atoms which is present in another molecule. It is strong force of attraction between the molecules.
<u>Thus, when multiple water molecules are there, there are connected by hydrogen bonding.</u>
True. A mole of anything has the same amount of molecules. 1 mole = 6.022 x 1023 molecules
Answer:
A
Explanation:
a vector quantity must have a direction. without a direction the value is called a scalar quantity
ie: velocity is a vector because it is how fast an object moves in a certain direction. speed is a scalar because it is how fast an object moves regardless of direction
Here you go! There are 0.9307 moles in 123.0 g of the compound. I solved this by using a fence post method. I calculated the number of grams in one mol of (NH4)2 SO4 and got 132.16.
I did this by finding the atomic mass of each element on the periodic table (my work is in the color blue for this step)
After that, i divided the given mass by the mass of one mol of the compound.
The answer is 0.9307 moles!! I hope this helped you! :))
