Answer : The mass of oxygen will be, 36.8 grams
Solution : Given,
Moles of water = 2.30 moles
Molar mass of 
= 32 g/mole
First we have to calculate the moles of oxygen.
The balanced chemical reaction will be,
From the balanced reaction we conclude that
2 moles of water decomposes to give 1 mole of
2.30 moles of water decomposes to give 
moles of
Now we have to calculate the mass of oxygen.
Therefore, the mass of oxygen will be, 36.8 grams
Answer:
10, True
Explanation:
Because weather is what conditions of the atmosphere are over a short period of time and climate is how the atmosphere behaves over a long period of time.
Answer:
The correct option is C. The level of organization best represented by the corn plant is : organism, the level of organization directly above organ system organ system
Explanation:
An organism can be described as a living thing made up of organ systems.
Plants are organisms that have levels of organizations similar to animals. Cells in plants make up tissues. There are mainly two types of tissues in plants: the meristematic tissue and non-meristematic tissue.
Just like animals, plants have organ systems. There are two kinds of organ systems mainly in plants: the shoot system and the root system. Hence, option C is the correct option.
Answer:
Na= 1, Ar= 8, V= 5, F= 7
Explanation:
You can determine the number of valence electrons in an element by looking the the group/column # on the periodic table. Elements in the same family/ group are organized by columns (vertical). Elements in the same column have the same number of valence electrons (electrons of the outermost shell) and consequently similar properties.
Simply put, GROUP #= # VALENCE E-
There are exceptions to this, especially when determining the amount of valence electrons in elements that are in a compound or in transition metal elements. For transition metals (that have different oxidation states- different # of valence electrons for the same element) I’d just look it up
