Water can be formed in the following reaction: 2H2 + O2 —> 2H2O

Chemistry
1 answer:
slega [8]3 years ago
8 0

Answer:

7 moles

Explanation:

Given data:

Moles of hydrogen = 7 mol

Moles of water formed = ?

Solution:

Chemical equation:

2H₂ + O₂ → 2H₂O

Now we will compare the moles of water with hydrogen from balance chemical equation:

              H₂          :        H₂O

                2          :           2

                7          :           7

So in the presence of excess oxygen and 7 moles of hydrogen seven number of moles of water produced.

Consider the following reaction: Cd (s) AgCl (aq) --> CdCl2 (aq) Ag (s) In this reaction, a. electrons are transferred from s
madam [21]

Answer:

a. electrons are transferred from silver in AgCl (aq) to Cd (s)

Explanation:

In this reaction Ag is reduced:

  • Ag⁺ + 1e⁻ → Ag⁰

While Cd is oxidized:

  • Cd⁰ → Cd⁺² + 2e⁻

With those two semi-reactions we can see that there's a transfer of electrons from silver in AgCl(aq) to the solid cadmium.

For the record, given that Ag was reduced, Cd was the reducing agent. And because Cd was reduced, Ag was the oxidizing agent.

A sample of thorium-234 has a half life of 25 days. Will the thorium undergo rafioacrive decay and be completely gone in 100 day
Sunny_sXe [5.5K]
I don't know terribly much about radioactive decay, but yes, it WILL decay. If it's half life is 25 days, it will be completely consumed in 50 days. By 100 days, it should be long gone. As far as I know, the reason for this is (besides the simple math which is self-explanatory) the Thorium has so many protons/neutrons, it's unstable and thus undergoes radioactive decay as it cannot maintain stable form.

I hope this helps! :)

Which ion(s) would bond by electrostatic attraction with an ion of Fluorine?
satela [25.4K]

Answer:

Intermolecular forces (IMF) (or secondary forces) are the forces which mediate interaction between atoms, including forces of attraction or repulsion which act between atoms and other types of neighboring particles, e.g. atoms or ions. Intermolecular forces are weak relative to intramolecular forces – the forces which hold a molecule together. For example, the covalent bond, involving sharing electron pairs between atoms, is much stronger than the forces present between neighboring molecules. Both sets of forces are essential parts of force fields frequently used in molecular mechanics.
