Which chemical equation below is not balanced?

Chemistry
1 answer:
Effectus [21]3 years ago
6 0

Answer:

B

Explanation:

The second one is not balanced correctly.

2 NaOH + 2HNO3 → 2NaNO3 + 2 H20

I didn't notice this before but it can be balanced without the twos.

 NaOH + HNO3 → NaNO3 +  H20

It was still wrong. It needed to have the twos removed, not 2 more added. Adding two more isn't wrong, but it should be balanced without 2s if at all possible.

How does the principle of electromagnetism explain the interaction between Earth’s magnetic field and the solar wind?
Otrada [13]

Answer:

Electromagnetism studies the attraction of two bodies within a magnetic field.

Electromagnetic interaction is one of the four fundamental forces of the known universe. The charged particles interact electromagnetically through the exchange of photons. Experimentally it was concluded that the lines of force of magnetic fields were always closed, eliminating the possibility of a magnetic monopole, so that within a magnetic field there are two poles, in the solar system the attraction between earth and wind Solar is by means of a field.

The most correct theory on this topic is the Earth itself is protected from the solar wind by its magnetic field, most of those charged particles, and most of those charged particles are trapped in the Van Allen radiation belt.

Explanation:

The magnetosphere or magnetosphere is a region around a planet in which its magnetic field deflects most of the solar wind, forming a kind of protective shield against high energy charged particles from the Sun. This magnetic or magnetosphere atmosphere does not It is only in the solar system, but also usually occurs on other planets such as jupiter and others (since it occurs on all planets with a magnetic field)

What is the pH of a weak base solution that has an [OH–] of 2.1 g 10–6 M? (4 points)<br><br> APEX
Amiraneli [1.4K]

Answer:

  • <u><em>8.3</em></u>

Explanation:

<u>1) Data:</u>

a) [OH⁻] = 2.1 × 10⁻⁶ M . . .  (the symbol g shown in the question is a typo)

b) pH = ?

<u>2) Formulae:</u>

  • pH + pOH = 14

  • pOH = log 1 /[OH⁻]

<u>3) Solution:</u>

  • pOH = log ( 1 / 2.1 × 10⁻⁶ ) = 5.7
  • pH = 14 - pOH = 14 - 5.7 =  8.3

How can you tell if a chemical is an ionic bond?
Klio2033 [76]
Classifying compounds as ionic or covalent
If a compound is made from a metal and a non-metal, its bonding will be ionic.
If a compound is made from two non-metals, its bonding will be covalent.
