Which formula is a molecular compound? A. NaCl B. CaO C. H2O2 D. MgS
bija089 [108]

Answer: Option (C) is the correct answer.

Explanation:

When atoms which are chemically combining tend to share electrons with each other, that is, forming covalent bonds with each other then the compound formed is known as a molecular compound.

For example, H_{2}O_{2} is a molecular compound.

This is because hydrogen atom has only one electron in its valence shell and an oxygen atom needs two electrons to complete its octet.

Therefore, sharing of electrons take place between the hydrogen and oxygen atom. As a result, it is a molecular compound.

Whereas NaCl, CaO, and MgS compounds are formed due to transfer of electron from one atom to another.

Thus, we can conclude that out of the given options H_{2}O_{2} formula is a molecular compound.

When calcium metal (Ca) reacts with oxygen gas (O2), it produces the ionic compound calcium oxide (CaO). Write the balanced equa
Vanyuwa [196]

Step-by-step explanation:

Hey there! Down here :D

\bf{Ca + O_2 \longrightarrow CaO}

Now , let's balance it by Multiplying 2 on Calcium Side.

\sf{2Ca + O_2 \longrightarrow 2CaO}

Is the Required Equation.

Hope it helps :)

<h3>Redox Reaction: Is it?</h3>

Yes, this is because:-

\sf{2Ca + O_2 \longrightarrow 2CaO}

  • Here, Calcium acts as Reducing Agent
  • And Oxygen is oxidizing agent.
  • And also, Cao gets oxidized.

It is also a Combination reaction.

\sf{A + B \longrightarrow AB}

  • Here A is Calcium
  • Here B is Oxygen.

If a is a rational number and b is an irrational number, then the sum a + b is
Mumz [18]

Answer:

C: Irrational

Explanation:

the reason i chose C because when you add a rational and irrational number together you still get a repeating number which is irrational.

For Example: Take a rational number 5 and Pi

if you ad those together 5+3.1415... you still get a repeating decimal, and repeating decimals are also irrational numbers.

Hope this helps :D
