There are 22.4 liters in 1 mole of O2 so you would need 89.6 liters
NaOH + HCl —> NaCl + H2O
I think this equation is already balanced as is.
You know when the equation is balanced when the number of moles of each element is equivalent on both sides of the reaction.
So in this case:
There is 1 Na to 1 Na
1 O to 1 O
2 H to 2 H
1 Cl to 1 Cl
Answer:
B. Halogen
Explanation:
Halogens are the family of chemical elements found in the group VIIA of the periodic table which means they possess seven (7) outer electrons. Some examples of halogens are Fluorine (F), Iodine (I), Bromine (Br), and Chlorine (Cl).
A halogen, or an element located in group 7A, will form a salt when reacted with a metal atom.
For example, when Chlorine reacts with Sodium it would form a salt known as Sodium Chloride.
Na + Cl ----> NaCl
Answer:
Melting ice and rising seas
Explanation:
At the same time global warming causes polar ice sheets and glaciers to melt. The combination of these changes is causing sea levels to rise, resulting in flooding and erosion of coastal and low lying areas.
In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size
