This dome-like shape forms due to the water molecules' cohesive properties, or their tendency to stick to one another. ... Water molecules at the surface (at the water-air interface) will form hydrogen bonds with their neighbors, just like water molecules deeper within the liquid.
Elements can combine to form molecules, like o2 or co2. elements combine to form molecules and these elements are joined together by chemical bonds i.e covalent bond in this molecule so option A is correct
hope this helps
Answer:
It would take 64 1-cm cubes to construct a 4-cm cube.
Explanation:
The volume of a cube is equal to the edge raised to the power of 3.
A 1-cm edge cube has a volume of V₁ = (1 cm)³= 1 cm³
A 4-cm edge cube has a volume of V₄ = (4 cm)³= 64 cm³
The number of small cubes required to fill the same volume than the big cube is:

Answer:
No
Explanation:
<em>No. </em>T<em>he demonstration does not violate the conservation of mass.</em>
<u>The law of conservation of mass states that mass can neither be created nor destroyed in a reaction. However, mass can be converted from one form to another during the reaction.</u>
In this case, even though the remaining bits of paper weigh 0.5 g while the original paper weighed 2.5 g, the ashes and smoke/gas from the burning will all add up to the lost weight of the paper.
<em>The burned part has been converted into other forms. If the smoke/gas and the ashes are properly captured, they will mark up with the weight of the remaining paper to give the weight of the original paper. </em>
