The appropriate answer is a. it involves a change in the molecular structure of the substance. A change in phase or state is referred to as a physical change. For example...liquid water freezing is a physical change because the state changes but solid water is still H20. Separating water into its constituent atoms, hydrogen and oxygen is a chemical change because the molecular structure of water is now non existent.
Answer:
Water (H20)
Explanation:
When an acid combine with a base, the reaction is called neutralization and it produces salt and water. This can be seen from the reaction between HCl and NaOH as shown below:
HCl + NaOH —> NaCl + H2O
From the above equation, we see clearly that salt (NaCl) and water (H2O) are the new products form.
Answer:
I just did the assignment it's "decreases"
Explanation:
If you guys came from Ed-genuity (i'm writing it like that because apperantly that is a swear word?) That means the next questions are "As you move from left to right across the periodic table, electronegativity..." and "As you move from top to bottom within a group, the first ionization energy...".
for electronegativity, it's increases and for ionization energy it's decreases. Hope this helps!
Look those up it will be easier
Answer:
Back into the sky and sewers/drainage holes
Explanation:
Water becomes evaporated from the sun and Rain also goes into drainage holes
