Answer:

All scientific research helps to generate new knowledge and improve the understanding of what is currently known, so it is important to support all scientific progress as long as it is developed in safe conditions and with the aim of increasing the knowledge of the world that we surrounds and of the universe.

Explanation:

The super-heavy elements are a group of elements of the periodic table that have very large and therefore very heavy nuclei, because of this they are very unstable (sometimes they are only stable less than a second and then they decompose into other atoms more stable) and that is why they have not been discovered so far in nature.

Super-heavy elements are studied in special laboratories as they are created when other atoms of smaller nuclei are "stuck" through a shock that requires a lot of energy. This clash that a new element can generate is achieved after millions of tests are carried out, and in each attempt a lot of information is generated that must be analyzed by super computers in order to determinate whether that attempt was successful (created a new element) or not.

That is why it takes a long time to study and develop new elements, but during this time and through the tests we get very important information that allows us to better understand the behavior of atoms and ratify or assume new theories that advance in the scientific community which may not currently be applicable but in the future.  

Thanks to the past investigations of scientist along the history they discovered all the elements of the current periodic table that allows us to undestand the properties of atoms and their uses for a huge amount of applications.

But the hunt for new elements started with efforts to develop nuclear power and the atomic bomb during World War II. At the time, uranium was the heaviest known element, sitting at number 92 in the periodic table.

Researchers quickly discovered that when uranium is placed in a nuclear reactor, a complex sequence of interactions leads to the production of several so-called transuranic elements (elements beyond uranium).

Probing around in the debris of the first hydrogen bomb test revealed two further transuranic elements, einsteinium and fermium, bringing the total to an even

An ionic compound that results from the reaction of an acid and a base is called a(n)______. the cation in this compound comes f
harkovskaia [24]

An ionic compound that results from the reaction of an acid and a base is called a(n) salt. the cation in this compound comes from the base while the anion comes from the acid.

When an acid and a base are together, they react to counteract each other's effects and create a salt.

Water is created when the OH(-) anion of the base and the H(+) cation of the acid mix.

A salt is a substance that is created when an anion from an acid and a base combine.

Common table salt, NaCl, is created when sodium hydroxide and hydrochloric acid are combined.

The positive ion (cation) of a base and the negative ion (anion) of an acid make up a salt.

A neutralizing reaction occurs when an acid and a base interact. Additionally, sodium chloride, generally known as table salt, is referred to as salt.

Which Locations are likely to have subatomic particles with the GREATEST mass?
wlad13 [49]

2 and 3, because there are the protons and neutrons which have a greater mass than the electrons which are found in the locations 1 and 4.

Explanation:

The atom contains a nucleus, which is made from protons and neutrons, and electrons which are found around the nucleus.

The mass of the atoms is concentrated in the very tiny space represented by the nucleus. Of course the electrons have a mass too, but is very small compared to the protons and neutrons, and we usually neglect its mass.

How much water would I need to add to 700 mL of a 2.7 M KCl solution to make a 1.0 M solution?
geniusboy [140]

Answer:

1190\ \text{mL}

Explanation:

M_1 = Initial Concentration of KCl = 2.7 M

V_1 = Volume of KCl = 1 M

M_2 = Final concentration of KCl = 1 M

V_2 = Amount of water

We have the relation

M_1V_1=M_2V_2\\\Rightarrow V_2=\dfrac{M_1V_1}{M_2}\\\Rightarrow V_2=\dfrac{2.7\times 700}{1}\\\Rightarrow V_2=1890\ \text{mL}

The amount of water that is to be added is 1890-700=1190\ \text{mL}.

Oxygen and Oxygen Ionic or Covalent? Defense how do you know
Marat540 [252]

Answer:

oxygen are covalent bonds because they require 2 more electrons to obtain their octet shell

so when they combine with any other element, they form a covalent bond
