What makes the element oxygen different from the element hydrogen?

Answers

Answer 1

Answer: the difference is due to the fact that one water molecule has two hydrogen atoms to one oxygen this means it takes two water molecules (2 H2O) to make one oxygen molecule (02) .At the same time however two molecules of water (2 H20) can make two molecules of hydrogen (2 H20)

The cell starts like this: o

First, the DNA inside the cell replicates and condenses into chromosomes. The also gathers all the materials necessary to divide and duplicates some organelles. (represented by 0)

Then the chromosomes pair up and are pulled to opposite poles of the cell. Then, the membrane pinches (invaginates) in in preparation to make two cells (8).

Then, cytokinesis occurs, when the cytoplasm splits and two new cells are formed (oo)

When a solid with a mass of 53.78 g is added to 50.0 ml of water in a graduated cylinder, the volume increases to 56.4 ml. Calculate the density of the solid.

Answers

Answer:

The answer is 8.40 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

volume = final volume of water - initial volume of water

volume = 56.4 - 50 = 6.4 mL

We have

[tex]density = \frac{53.78}{6.4} \\ = 8.403125[/tex]

We have the final answer as

8.40 g/mL

Arrange the following elements in order from least to greatest electronegativity:
Ca, F, Ne, Fe?

Answers

Answer:

The electronegativity from order of least to highest is:

Ne, Ca, Fe, F

Explanation:

Elements in the periodic table have been arranged based on their level of electronegativity (which is the ability of an atom to attract electrons).

According to Paulings scale of rating elements based on their electronegativity, the electronegativity value of Fe, Ca, Ne, and F are 1.83, 1, 0 and 3.98 respectively.

Hence, based on Pauling scale, the order of electronegativity from least to highest is:

Ne > Ca > Fe > F

lonic bonds tend to form between two atoms with what characteristics?​

Answers

Answer:Ionic bonds are formed through the exchange of valence electrons between atoms, typically a metal and a nonmetal. The loss or gain of valence electrons allows ions to obey the octet rule and become more stable. Ionic compounds are typically neutral. Therefore, ions combine in ways that neutralize their charges.

Explanation:

Ionic bonds tend to form between two atoms with a high electronegativity difference.

Explanation:

An Ionic bond is defined as a chemical bond in which the complete transfer of electrons occurs from one atom to another.The transfer of electrons occurs from less electronegative atom to highly electronegative atomThe high electronegativity difference between the atomsCompounds with ionic bonds categorized as ionic compounds

So, from this, we can conclude that ionic bonds tend to form between two atoms with a high electronegativity difference.

at 25°C
. Which of the following graphs shows the distribution of speeds for a sample of O2(g)
at 25°C
(dashed line) ?

Answers

Answer:

A

Explanation:

The Maxwell-Boltzmann equation, is the basis for discussion of the kinetic theory of gases. From it we can understand how gases are distributed at a particular temperature.

Let us remember that the kinetic energy of all gases is the same at the same temperature. However, the distribution of gases depends on their molecular weight at that particular temperature.

Heavier molecules are known to move slowly compared to lighter molecules. Heavier molecules generally have a smaller distribution while lighter molecules spread out.

For this reason, oxygen which is heavier than nitrogen has a smaller distribution as shown in the diagram (molar mass of oxygen = 32g/mol) while nitrogen (molar mass 28 g/mol) has a distribution that is more spread out being a lighter molecule. Hence the option chosen.

What is the chemical equation?

A chemical equation can be defined as the expression of a chemical reaction in terms of the chemical symbols of the substances. A chemical equation has reactants, formed products, and an arrow indicating the direction of the reaction.

The equation in which the number of atoms of each element is equal on either side of the chemical equation of a reaction is called a balanced chemical equation.

According to the law of mass conservation, the total mass of the elements on the reactant side should be equal to the total mass of elements on the product side.

Given, the chemical equation of the reaction of nitrogen ad oxygen gas can be written as:

2N₂  +  O₂ → 2N₂O

The number of molecules of Nitrogen gas is 2 and the molecules of oxygen gas are one and the molecules of N₂O are equal to 2.
