Answer:
Estuaries are often called the “nurseries of the sea”
Explanation:
Because so many marine animals reproduce and spend the early part of their lives there.
Answer:
Explanation:
First Question. Answer is: B. They are different.
For examle, balanced chemical reaction of forming water from hydrogen and oxygen:
2H₂ + O₂ → 2H₂O.
During chemical reaction no particles are created or destroyed, the atoms are simply rearranged from the reactants to the products.
Oxygen (element) has boiling point of -183°C and hydrogen has boiling point of -253°C. In this chemical change water (compound) is produced and it has new boiling point, boiling point of water is 100°C.
Ununoctium, also known as eka-radon.
hope this helps!
It produces mercury and oxygen gas.
Answer:
see below
Explanation:
1. Predicting products (double replacement): ab + cd ---> ad + cb
KNO₃(aq) + Fe(OH)₃(s)
2. balance the equation
3KOH (aq) + Fe(NO3)₃ (aq) ---> 3KNO₃(aq) + Fe(OH)₃(s)
3. I don't know if you need this but ionic equation: only aqueous things get split into ions; gas, liquid, and solids stay together
3K⁺(aq) + 3(OH)⁻(aq) + Fe³⁺(aq) + 3NO₃⁻(aq) ---> 3K ⁺(aq) + 3NO₃⁻(aq) + Fe(OH)₃(s)
removing things on both product and reactant side
3(OH)⁻(aq) + Fe³⁺(aq) --->Fe(OH)₃(s)
