Answer: if you build a wall that when the water hits it it seperates the sand from the water and spits the water onto the ocean side of the wall and spit the sand on the beach side but also build a bridge to that people can get to the water if wanted
Explanation:
if you put a wall it would block you from getting to the water or vice versa.
Answer:
B
Explanation:
To form hydrogen bondings between the molecules, the compound needs a highly electronegative atom (usually N, O, or F) bonded with a hydrogen atom;
and that the highly electronegative atom has lone pair outermost shell electrons.
In the 5 options, only B (CH3OH) has an N, O, or F atom that has lone pair outermost shell electrons (2 lone pairs on each O atom), so it can form hydrogen bonds within its molecules.
Hydrogen bonds are stronger than the van der Waals' forces between its molecules (that exist regardless of whether there are hydrogen bonds).

The 0 after 1 is not significant and does not affect the value of the number; therefore, when the number will be rounded to two significant figures, it will become 2.1, so it will be the same.
<h3>Answer:</h3>
2 C₃H₈O + 9 O₂ → 6 CO₂ + 8 H₂O
<h3>Explanation:</h3>
This is the combustion reaction in which Isopropanol, an organic compound is burnt in the presence of Oxygen to produce Carbon dioxide and water vapors.
The General reaction is as,
Isopropanol + Oxygen → Carbon dioxide + Water
Chemical formulae of above compounds and molecule are,
Isopropanol = C₃H₈O
Oxygen = O₂
Carbon Dioxide = CO₂
Water = H₂O
Hence, the balance chemical equation can be written as,
2 C₃H₈O + 9 O₂ → 6 CO₂ + 8 H₂O
