Even if hydrogen is in 1 group originally you can still say it is in 6 groups.

Even though Hydrogen is originally in group 1, based on this property, we can say it is in group 6.

Because:

Group 6 would mean that it only needs 2 more valence electrons till the octet (8 valence electrons). This would make it reactive, yet, in normal conditions, unlike group 7.

What is bond stability??​
Nookie1986 [14]

Answer:

Bond order is a counting method that gives an idea about numbers of electrons shared between atoms. A species with a higher bond order is more stable. A bond order equal to 2 is a double bond, and a bond order of 3 is a triple bond.

Convert 7.1X1025 molecules of water to moles
scoundrel [369]

Answer:

Moles of water in 7.1×10²⁵ molecules are 118 mol.

Explanation:

Given data:

Number of molecules of water = 7.1×10²⁵ molecules

Moles of water in 7.1×10²⁵ molecules = ?

Solution;

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

1 mole = 6.022 × 10²³ molecules of water

7.1×10²⁵ molecules of water × 1 mol / 6.022 × 10²³ molecules of water

1.18×10² moles of water 0r 118 moles of water

Try to rationalize the sign of ΔS∘rxn in each case.
bonufazy [111]

Answer:

a) decrease, gas

b) increase, gas

c) liquid

d) increase, solid

Explanation:

Entropy refers to the degree of disorderliness of a system. If the number of moles of gas increases from left to right in a reaction, the entropy of the system increases positively.

Similarly, when the number of liquid molecules remain constant, there could only be a very little increase in entropy.

However, solids have the least entropy and the entropy of a system decreases when a system yields solid products.
