How does radiation differ from convection? (104 points)
a Radiation can move through empty space to transfer heat; convection cannot.
b Radiation needs a medium in order for heat to transfer; convection does not.
c Radiation requires objects to have direct physical contact; convection does not.
d Radiation transmits heat by circulating particles in an object; convection does not.
Answer:
Choice A
Radiation can move through empty space to transfer heat; convection cannot.
A student measured the pH of five different solutions. Match each pH with the term that best describes each solution.
Answer:
7ph - Neutral
1ph - weak base
14ph - strong acid
10ph - strong base
5ph - weak acid
Hope this helps!
Explanation:
1 is the weakest and 14 is the strongest
What kind of chemical bond is formed between nonmetals? Explain your answer.
Answer:
The ionic bond is formed due to an electrostatic force of attraction between two oppositely charged ions. This bond is usually formed between a metal and a nonmetal. Prior to the electrostatic attraction, there is a total transfer of valence electrons from one atom to the other atom.
Explanation: hope that helps
In general, nonmetals form covalent bonds, metals and nonmetals form ionic bonds, and metals form metallic bonds.
What are non-metals?Non-metals are natural materials that do not generate heat or electricity and are structurally brittle, making them difficult to roll, mold, extrude, or press.
Non-metallic elements in the periodic table include hydrogen, carbon, nitrogen, oxygen, phosphorus, arsenic, and selenium.
Ionic compounds are formed when metals and nonmetals combine, whereas covalent compounds are formed when nonmetals combine with other nonmetals.
Metal atoms have only a few electrons in their outer shell, whereas non-metal atoms have many electrons.
This means that metals are more likely to react with nonmetals. Electrons transfer from the metal to the nonmetal when it reacts with it.
Thus, there will be covalent bonding between nonmetals.
