liquid is fluid in motion, needing to be contained. while a solid state of matter is as such and won't run down the cabinet
Answer:
Dermal tissue of the stems and leaves is covered by a waxy cuticle that prevents evaporative water loss. Stomata are specialized pores that allow gas exchange through holes in the cuticle. Unlike the stem and leaves, the root epidermis is not covered by a waxy cuticle which would prevent absorption of water.
Explanation:
Answer:
5.51g
Explanation:
Using the following formula:
Q = m × c × ∆T
Where;
Q = amount of heat in Joules
m = mass/weight of Aluminum
c = specific heat of Aluminum (0.900 J/g°C)
∆T = change in temperature.
Based on the information given in this question, Q = 175.6 joules, ∆T = 35.4°C, c = 0.900 J/g°C.
Using, Q = m × c × ∆T
175.6 = m × 0.900 × 35.4
175.6 = 31.86m
m = 175.6/31.86
m = 5.51g
The weight of the aluminum sample is 5.51g.
<u>Answer:</u> The mass of the reactants is always equal to the mass of the products.
<u>Explanation:</u>
Law of conservation of mass states that mass can neither be formed nor be destroyed but it can only be transformed from one form to another. This law is followed by all the balanced chemical reactions.
This law simply means that the total mass on the reactant side is always equal to the total mass on the product side.
For example: Formation of water from hydrogen and oxygen gas.
Total mass on the reactant side =
Total mass on the product side =
As, the total mass on the reactant side is equal to the total mass on the product side. Hence, this equation follows law of conservation of mass.
