Iron Man died in Infinity Wars, so Mrs. Nogaki has decided that she is going to make her own super hero suit to save the world. She has decided that her suit must have these properties.• It must not be brittle (it must with stand Hulk’s temper without cracking)

• It must have a high melting temperature (so the rockets don’t melt it)

Which kind of bonds should the material Mrs. Nogaki chooses to make her suit from have?

Question 6 options:

Metallic Bonds


Covalent Bonds


Ionic Bonds

Answer is (2) - hydrogen carbonate

Explanation:

NaHCO₃ is an ionic compound which is made from Na⁺ and HCO₃⁻ ions. The decomposition is

NaHCO₃ → Na⁺ + HCO₃⁻

Among the resulted ions, Na⁺ is a monatomic ion while HCO₃⁻ is a polyatomic ion.

Polyatomic ions mean ions which are made of two or more different atoms.

HCO₃⁻ is made from 3 atoms as H, C and O. The name of HCO₃⁻ ion is bicarbonate or hydrogen carbonate.

Answer:

A neutral atom can become positively charged by loosing electrons

Explanation:

this is because the number of protons are the same as the number of electrons and so by loosing electrons there are now more protons and so they become positively charged

Answer:

b

Explanation:

losing electrons,the atom becomes a cation ,,in other words becomes positively charged

Final answer:

An electric field is created by particles that have a charge. These can be either positively or negatively charged. The direction of the field is away from positive charges and towards negative charges.

Explanation:

An electric field is generally created by particles that have a charge. These particles can either be positively or negatively charged. The direction of the electric field is always directed away from positively charged particles and towards negatively charged particles. The magnitude (or strength) of the electric field at a point in space is defined as the force that a positive test charge would experience if it was placed at that point divided by the magnitude of the test charge. For example, if we place a positive test charge in the field produced by another positive charge, the test charge will be repelled - illustrating the direction of the electric field. Hence, even though moving charged particles and radioactive particles can create an electric field, the most generalized answer to this question is that an electric field is created by particles that have a charge regardless of their state of motion or radioactivity.

Final answer:
The difference between covalent bonds and ionic bonds is b. Covalent bonds involve the sharing of electrons between atoms; ionic bonds involve the electrical attraction between atoms.

Final answer:

In covalent bonds, atoms share pairs of electrons to achieve a stable electron configuration. This sharing creates a strong bond between the atoms, and they are typically nonmetals. In ionic bonds, there is a transfer of electrons from one atom to another, resulting in the formation of ions with opposite charges.

One atom becomes positively charged (cation), and the other becomes negatively charged (anion). The electrical attraction between these oppositely charged ions holds them together, forming an ionic bond. Ionic bonds typically form between a metal and a nonmetal.
