Answer:
Lead
Explanation:
Lead (Pb) has atomic number 82
Ex Polonium (Po) has atomic number 84 and mass number 212
Answer:
c and o
Explanation:
Carbon and Oxygen cannot react to form an ionic compound because the two elements are non-metals.
- To form an ionic bond, a metal combines with a non-metal through electrostatic attraction of oppositely charged ions.
- This leads the bond formation.
- Carbon is a non-metal, with oxygen, they will prefer to form a covalent bond where they share their electrons
Answer:
fill the flask with water. apply heat, when you see the vapor you will know is heat
Answer:
Explanation:
Similarities.
Both Ionic and covalents bond produce exothermic reactions.
They are both neutral.in Ionic bonds, the two opposite charge will terminate each other and in covalent, the neutral molecules tend to share electrons.
Difference
Ionic bonds have high polarity while covalent have low.
Ionic bonds have no definite shape, covalent have.
Ionic have high melting points, covalent have low.
Io ic have high boiling point, covalents have low.
Explanation:
Mixture is the physical Combination Of two or Substance
Example
a mixture of sugar and water.
Compound is the chemical combination of two or more metals.
Example.
a mixture of hydrogen and water.
A mixture of hydrogen and oxygen forms water or H2O
whereas The dihydrogen monoxide parody involves calling water by an unfamiliar chemical name, most often "dihydrogen monoxide" (DHMO), and listing some of water's properties in a particularly alarming manner, such as accelerating corrosion (rust) and causing suffocation (drowning). The parody often calls for dihydrogen monoxide to be banned, regulated, or labeled as dangerous. It plays into chemophobia and demonstrates how a lack of scientific literacy and an exaggerated analysis can lead to misplaced fears. The parody has been used with other chemical names such as hydrogen hydroxide, dihydrogen oxide, hydroxic acid, hydric acid and oxidane.
