Total 5 valence electrons nitrogen provide to distribute when constructing the Lewis structure of NH3.

Ammonia (NH3) is a colourless, pungent gas and is made up of nitrogen and hydrogen. It's molecular geometry is trigonal pyramidal and it's hybridization is sp3 hybridization. In NH3, N is a central atom which contributes 5 valence electrons as we know Nitrogen belongs to the 15th group and each hydrogen contributes 1 electrons and that 1 electron is its valence electron. In the chemical compound NH3, we can see that there is 1 Nitrogen and 3 Hydrogen atoms are present, so the total no. of valence electrons in ammonia is 8 electrons (1x5 electrons of N and 3x1 electrons of Hydrogen). So, Nitrogen contribute 5 valence electrons in which 3 electrons are utilised for the 3 N-H bonds and the remaining 2 are localised on the Nitrogen as a lone pair.

CH, (g) + 20 (g) → CO(g) + 2H 0(g)

galben [10]

<h3>Answer:</h3>

126.14 g

<h3>Explanation:</h3>

Complete combustion of hydrocarbons yields water and carbon dioxide.
Methane is a hydrocarbon in the homologous series known as alkanes.
Methane undergoes combustion in air to produce water and carbon dioxide according to the equation below.

CH₄ (g) + 2O₂ (g) → CO₂(g) + 2H₂O(g)

<u>We are given;</u>

3.5 moles of Methane

We are required to determine the mass of H₂O produced

<h3>Step 1: Moles of H₂O produced</h3>

From the equation 1 mole of methane undergoes combustion to produce 2 mole of H₂O.

Therefore, Moles of methane = Moles of H₂O × 2

Hence, Moles of H₂O = 7.0 moles

<h3>Step 2: Mass of H₂O produced </h3>

We know that; mass = Moles × Molar mass

Molar mass of water = 18.02 g/mol

Therefore;

Mass of water = 7.0 moles × 18.02 g/mol

= 126.14 g

Thus, the mass of water produced is 126.14 g

. Which characteristic of water will allow a paperclip to remain floating on water when the paperclip is gently placed on top of

Len [333]

Answer:

The answer is surface tension.

Explanation:

The high surface tension helps the paper clip - with much higher density - float on the water. The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension. hope this helps :)

Without looking at the periodic table, identify the group, period, and

kobusy [5.1K]

the group : 2

periode : 6

block = 2

atomic number = 56

<h3>Further explanation </h3>

We can divide the periodic system into several parts:

1. Block s: groups 1 and 2 (having a configuration of 1s-7s) consist of active metals except for H (non-metals) and He (noble gases)

2. Block p: group 13-18 (has a 2p-6p configuration), also called a representative element because it includes metals, non-metals and metalloids

3. Block d: group 3-12 (having the 3d-6d configuration), are transition metal elements

4. Block f: Lanthanides and Actinides (having a 4f-5f configuration), are inner transition elements that are also metal

The element with the electron configuration : [Xe]6s²

The outer shell 6s² :

Electron configuration :

1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s² : electron =56

group⇒valence electron ⇒2

period⇒the greatest value of the quantum number n⇒6

The element that is in period 6, and belongs to group 2 and has the atomic number 56 and in the block s
