The answer is C. In order to balance this equation you have to look at the 2AlCl3. The first Cl2 needs to equal 6 because 2x3=6. So the answer is 3.
Answer:
Plants exchange oxygen and carbon dioxide. The oxygen is used for respiration and is also a waste product of photsynthesis. The carbon dioxide is used for photsynthesis.
During the day time, the stomata of the plant will open to let the carbon dioxide in for photsynthesis. Cabron dioxide diffuses into the leaf down a concetration gradient. oxygen will leave the leaf down the concentration gradient.
This process is the gas exchnage of plants.
How stomata open: Stomata open during the dayby absorbing water vapor, become turgid and and open. During the night, the stomata becomes flaccid and floppy. this causes it to close.
Explanation:
Answer:
B) The mass of the reactants equals the mass of the products,
Explanation:
Given that the reaction is balanced, the mass of the reactants must equal to the mass of the products.
We know this by virtue of the law of conservation of mass.
The law of conservation of mass states that "in a chemical reaction, matter is neither created nor destroyed but atoms are rearranged".
Therefore, if the reaction is chemically balanced, the mass of reactants must be the same as the mass of the products in the reaction.
The second choice is the right one.
As the action potential passes through, potassium channels stay open a little bit longer, and continue to let positive ions exit the neuron. This means that the cell temporarily hyperpolarizes, or gets even more negative than its resting state.
