What are Boron and Potassium?

Boron is a chemical element with the symbol B and atomic number 5. Produced entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, it is a low-abundance element in the Solar System and in the Earth's crust. It constitutes about 0.001 percent by weight of Earth's crust while potassium is a chemical element with the symbol K and atomic number 19. Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force. Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure.

What are boron and potassium used for?

Boron is a mineral that is found in food and the environment. People take boron supplements as medicine. Boron is used for building strong bones, treating osteoarthritis, as an aid for building muscles and increasing testosterone levels, and for improving thinking skills and muscle coordination while Potassium is a mineral that plays many important roles in the body. Food sources of potassium include fruits (especially dried fruits), cereals, beans, milk, and vegetables. Potassium is most commonly used for treating and preventing low potassium levels, treating high blood pressure, and preventing stroke.

When magnesium reacts with chlorine, magnesium ions, Mg2+, and chloride ions, Cl−are formed. In this reaction, magnesium atoms A

Slav-nsk [51]

Answer: In the reaction, magnesium atoms lose electrons.

Explanation:

An ionic compound is defined as the compound which is formed when electron gets transferred from one atom to another atom. These are usually formed when a metal reacts with a non-metal or a metal reacts with a polyatomic ion or a reaction between two polyatomic ions takes place.

Magnesium is 12th element of the periodic table having electronic configuration of $1s^22s^22p^63s^2$

This element will loose 2 electrons to form $Mg^{2+}$ ion

Chlorine is 17th element of the periodic table having electronic configuration of $1s^22s^22p^63s^23p^5$

This element will gain 1 electron to form $Cl^-$ ion

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

The ionic compound formed is $MgCl_2$

Hence, in the reaction, magnesium atoms lose electrons.

How many atoms are in TWO water (H20) molecules?

WINSTONCH [101]

Answer:

6

Explanation:

There are two atoms of hydrogen and one atom of oxygen in each water molecule, making the formula H 2 O. So in two there would be 4 hydrogen and 2 oxygen

The chemical formula of ordinary sugar is C12H22O11. Calculate the mass of 7.35 mol of sugar.

ch4aika [34]

First, you need to find the mass of 1 mol of sugar. Mass, or molar mass, can simply be found by adding the masses of the individual elements. These are given to you on the periodic table.

$C_{12}H_{22}O_{11}$
