Answer:
one molecule is made up of one type of molecule
Explanation:if it is one molecule it has to me made of other atoms and not of other molecules
Use stoichiometry 3.75moles k* 39.10g k\1 mole k= 146.63g k
Following reaction takes place between LiOH and HNO3
LiOH + HNO3 → LiNO3 + H2O
Thus, 1 mole of LiOH reacts with 1 mole of HNO3 to form 1 mole of LiNO3.
Now,
Number of millimoles of LiOH consumed = <span>36.90 X 0.100 = 3.690
</span>∴Number of millimoles of HNO3 present = 3.690
<span>
Now, Molarity of HNO3 = </span>

=

= 0.0738 M
Thus, <span>
molarity of the HNO3 solution is 0.0738 M</span>
Answer:
One can of cola contain 0.16 kcal of carbohydrates.
Explanation:
Given data:
mass of cola can = 40 g
kilocalories of carbohydrates = ?
Solution:
we know that there are 4 cal of carbohydrates per gram.
40 g × 4 cal/g = 160 cal
Now we will convert calories into kilocalories. There are 1000 calories in one kilocalories so,
160/1000 = 0.16 kcal
so, one can of cola contain 0.16 kcal of carbohydrates.
Answer:
The ionization energy of each successive element generally decreases
Explanation:
The ionization energy increases in the periods of the periodic table and decreases in the groups. If the atom is very small, we will need a lot of energy to release the electron, while if the atom is larger the energy will be greater.
