Choose the transition metal among the following which has only single ionic charge ?

Chemistry
1 answer:
Law Incorporation [45]3 years ago
7 0

Answer:

Silver (Ag)

Explanation:

The electronic configuration of copper is shown below;

[Kr]4d10 5s1

We can see that there is only one 5s1 electron. Hence Ag^+ tends to display a pseudo noble gas configuration. This pseudo noble gas configuration explains why silver is prevalent in the +1 oxidation state.

The other transition metals have many stable oxidation states found in nature. Chromium is observed both in +3 and +6 oxidation states. Iron is found in +2 and +3 oxidation states and copper is mostly stable in the +2 oxidation state since the +1 oxidation state readily disproportionate.

Hence silver tends to have only a single ionic charge for reasons aptly stated above.

Suppose the volume of a container is decreased, but the same number of gas molecules is present at the same temperature. What wi
charle [14.2K]

Answer: Option (C) is the correct answer.

Explanation:

When the volume of a container is decreased and same number of gas molecules are present inside the container at the same temperature then it means that more number of gas molecules are spread per unit volume.

As earlier when the volume of container was more then the molecules were widely spread inside the container but on decreasing the volume of container, molecules come closer to each other and hence there will be increase in molecules per unit volume.

if you supply 3600 kJ of heat, how many grams of ice at 0°C can be melted, heated to its boiling point? (Make M your X in equati
DanielleElmas [232]

Answer:

=1.36kg

Explanation:

First heat is absorbed to melt the ice- latent heat of fusion of ice then heat is absorbed to raise the temperature to 373K

The specific heat capacity of water is 4.187kJ/kg/K while  the latent heat of fusion of ice is 2230kJ/kg/K.

Letting the mass of the ice to be =x

x×2230kJ/kg/K + x×4.187kJ/kg/K×100K= 3600kJ

2230x+418.7x=3600

2647.8x=3600

x=1.36 kg

The molecule with the largest dipole moment (a) co2 (b) h2o (c) ch4 (d) c2h4 (e) ph3
storchak [24]

The molecule with the largest dipole moment will be CH_{4}.

A dipole moment would be a unit used to describe how far apart two electrical charges are from one another. Dipole moments represent a type of vector. The direction could be from negative charge to positive charge, while the magnitude has been equal to the charge times the distance between most of the charges.

The polar bonds, of  CO_{2} as well as H_{2} O have chemical configurations where the polarity cancels, leaving no net dipole. Regardless of the molecule's shape, CH_{4} lacks a net dipole due to its non-polar links.

The molecule with the largest dipole moment will be CH_{4}.

Hence the correct answer will be option (c).

Why do northern lights appear in different colors? Because charged particles of solar wind ignite different gases in Earth's atm
Fofino [41]

Answer:

It is A. Because charged particles of solar wind ignite different gases in Earth's atmosphere.

Explanation:

Since the solar wind from the sun is too radioactive for humans (they would die), once the charged particles hit the earth's atmosphere it shows its color. Every element has its own color and once it hits the atmosphere it really starts to show.
