Hey there!
Your PHYSICAL properties of calcium is/are....
- COLOR which gives you a silvery whitish metallic color
- PHASE which is pretty much solid
- HARDNESS which is quite soft metal
- CRYSTALLINE STRUCTURES which is like a cubic symbol
- DUCTILITY which can be misused into millions of thin specs
- MALLEABILITY which forms the shape or vent
- MELTING POINT which is estimated to about 850 degree Celsius
- BOILING POINT which is estimated to 1,480 degree Celsius
The CHEMICAL properties of calcium is/are...
• CHEMICAL CODE
• OXIDATION which is used for the steel
• ISOTOPES calcium has about 6 of them
• COMPOUNDS includes marble and limestone (there’s more)
• FLAMMABILITY when it is burned into the air or in the oxygen it will most likely catch on fire
• REACTION TO WATER (H2O) it responds to the water fast in the beginning but slowly the reaction slows down due to the feeling of your calcium
• REACTION TO ACIDS it is exceedingly reactive
Good luck on your assignment and enjoy your day!

Answer:
HClO₃(aq) + NaOH(aq) ⇒ NaClO₃(aq) + H₂O(l)
Explanation:
We have the products of a reaction and we have to predict the reactants. Since the products are salt and water, this must be a neutralization reaction. In a neutralization reaction, an acid reacts with a base. To form NaClO₃, the acid must be HClO₃(aq) and the base NaOH(aq). The balanced chemical equation is:
HClO₃(aq) + NaOH(aq) ⇒ NaClO₃(aq) + H₂O(l)
Answer:
Atomic mass of nitrogen = 14.0067 amu.
Explanation:
Isotopes can be defined as two or more forms of a chemical element that are made up of equal numbers of protons and electrons but different numbers of neutrons.
Generally, the isotopes of a chemical element have the same chemical properties because of their atomic number but different physical properties due to their atomic weight (mass number).
The two isotopes of nitrogen are nitrogen-14 and nitrogen-15.
Given the following data;
Relative abundance of N-14 = 99.63%
Atomic mass of N-14 = 14.003
Relative abundance of N-15 = 0.37%
Atomic mass of N-15 = 15.000
The atomic mass is;
14.003 × (99.63/100) + 15.000 × (0.37/100)
Atomic mass = 14.003 × (0.9963) + 15.000 × (0.0037)
Atomic mass = 13.9512 + 0.0555
Atomic mass = 14.0067 amu.
<em>Therefore, the atomic mass of nitrogen is 14.0067 amu. </em>
