Answer:
C₅H₁₀O₅
Explanation:
Let's consider a compound with the empirical formula CH₂O. In order to determine the molecular formula, we have to calculate "n", so that
n = molar mass of the molecular formula / molar mass of the empirical formula
The molar mass of the molecular formula is 150 g/mol.
The molar mass of the empirical formula is 12 + 2 × 1 + 16 = 30 g/mol
n = (150 g/mol) / (30 g/mol) = 5
Then, we multiply the empirical formula by 5.
CH₂O × 5 = C₅H₁₀O₅
Answer: None of the above statements is false.
Explanation:
In a solid substance, particles are closely held together due to which a solid substance has definite shape and volume. Therefore, solids are also incompressible in nature.
In liquids, the molecules are slightly away from each other due to which they can slide past each other. Hence, liquids do not have a fixed shape but they have a definite volume. Liquids are also incompressible in nature.
In gases, the particles are held by Vander waal forces due to which they move rapidly from one place to another. Hence, gases are highly compressible in nature.
Thus, we can conclude that none of the given statements are false.
Ever seen a waterfall ? what do you think happens when all that water slams into the ground below ? same as when you turn a hosepipe on a flowerbed.
also, there's hydraulic cracking where water gets into cracks and freezes, splitting rocks apart.
fast moving water can carry sediment and roll rocks along the bottom. if the water slows down, it drops the rocks and heavier sediment. if it floods a field, say, then drains away, the grass will also filter smaller particles out, or the water might evaporate and leave fine sediment behind.
Mercury would have the greatest density
