What type of covalent bond is present in a molecule of hydrogen?

Chemistry

Answer:

In molecular hydrogen, H2H2, the two hydrogen atoms are joined by a nonpolar covalent bond. There’s a lot to unpack in that term, so let’s get started.

What is a covalent bond? A covalent bond happens when two atoms share electrons. (Compare it to an ionic bond, which happens when one atom loses electrons to the other atom.) In a single covalent bond, each atom shares one electron with the other atom, so there are a pair of electrons that simultaneously belong to both atoms.

Sometimes the atoms share electrons evenly; sometimes they don’t. If one of the atoms has a greater attraction for electrons than the other atom does, the electrons are drawn more strongly to one side of the bond than to the other. We call that a polar covalent bond. But in the case of H2H2, where both atoms are exactly the same, the electrons are evenly distributed. That’s called a nonpolar covalent bond.

If you want to get even more technical, you could say that the bond between the hydrogen atoms is a sigma bond. Covalent bonds happen when atoms’ orbitals overlap. (Orbitals are the regions where electrons are most likely to be found.) A sigma bond is formed when the area of overlap is directly between the two atomic centers. (Orbitals can also overlap side-to-side, which is called a pi bond, but that’s not what happens in a hydrogen molecule.)

Answer:

To plot a graph, you put the independent variable on the y-axis and the dependent on the x-axis. This might sound really hard, but it's not.

A dependent variable is something that is changed by other factors. For example, in this question, the temperature is dependent on the time. You can't change time by temperature, it's impossible. But you CAN change temperature by the more time that goes by. This makes Time independent and Temperature Independent.

You write the graph so that Time (1-10) goes up the side (the y-axis), starting from the bottom left (this point is called the origin). Then you write the Temperature on the bottom, from left to right. The numbers you are given have to have the same amount of points (the little squares you see) in between them, and you have to be able to fit all of the numbers on the graph.

The last step is to plot the points on the graph so they match up. If the time is 1, then you go to where the time says one and move over to the right to where it is the correct temperature. That is where you put your point. You keep doing this until you have all the points plotted and you can connect the dots.

What is the electron configuration of a chlorine ion in a compound of BeCl2
Liula [17]
The electronic configuration of a chloride ion in a compound of BeCl2  is

2.8.8

This is because   chlorine atom   which electronic configuration 2.8.7  gain one electron  form Be to  form chloride ion with 2.8.8 electronic configuration.  BeCl2 is an ionic bond which is formed by a metal and a non metal.metal (Be)loses electron  and become positively charged while  non metal (Cl2) gain electron  and become negative charged.

What is the main use of Cellulosic Ethanol?
KonstantinChe [14]

Explanation:

Cellulosic ethanol is ethanol (ethyl alcohol) produced from cellulose (the stringy fiber of a plant) rather than from the plant's seeds or fruit. It can be produced from grasses, wood, algae, or other plants. It is generally discussed for use as a biofuel.

A child on a high dive has a mass of 40 kilograms. If the high dive is 10 meters in the air, what is the potential energy?
Otrada [13]

Answer:

<h2>3920 Joules</h2>

Explanation:

The potential energy of a body can be found by using the formula

PE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 9.8 m/s²

From the question we have

PE = 40 × 9.8 × 10

We have the final answer as

<h3>3920 J</h3>

Hope this helps you
