I would say A and C. The circulatory system moves blood and nutrients similar to the plant moving water and nutrients. The endocrine system is responsible for hormones, glands and other such functions.
Explanation:
Reaction equation for the given chemical reaction is as follows.
Equation for reaction quotient is as follows.
Q = 
= 
= 0.256
As, Q > K (= 0.12)
The effect on the partial pressure of 
as equilibrium is achieved by using Q, is as follows.
- This means that there are too much products.
- Equilibrium will shift to the left towards reactants.
- More is formed.
- Partial pressure of increases.
Answer:
structure formula C3H5CH3
Answer:
Aristotle believes that all material substances are matter and form.
Explanation:
If you remember from the four causes, the matter is one cause and form is another cause. Substance theory says that substances are the ultimate things in the universe
Answer:
Mass = 12.276 g
Explanation:
Given data:
Number of molecules of H₂S = 2.16 × 10²³
Mass in gram = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
Number of moles of H₂S:
2.16 × 10²³ molecules × 1 mole /6.022 × 10²³ molecules
0.36 moles
Mass = number of moles × molar mass
Mass = 0.36 mol × 34.1 g/mol
Mass = 12.276 g
