Is MgS ionic or covalent

Answers

Answer 1

Answer:

Ionic

Explanation:

Mg has 2 electron in it's outermost orbit, by donating this two electron to Sulfur it get stable mg 2+ electronic configuration while sulfur has 6 electron in it's outermost shell ,so sulfur accept this 2 electron and complete it's octet and become s2–.

There are only 90 naturally occurring elements on Earth but there are millions of different substances explain how this is possible and describe how it applies to at least three examples

Answers

Answer:

See explanation

Explanation:

While it is true that there are only about 90 naturally occurring elements, these elements are capable of combining with each other to form millions of substances.

Most of the substances that we see around us today result from a combination of one or more of these naturally occurring elements.

Let us look at three examples;

The carbohydrate in food is composed of carbon, hydrogen and oxygen

The stainless steel materials we use are composed of iron, carbon and other trace elements

Glass is made up of silicon, oxygen and other elements

Only 90 naturally occurring elements capable of combining with each other to form millions of substances.

Compounds:

When two or more elements combine in a certain ratio to form a molecule.

For example-

Water is made up of two hydrogen and one Oxygen ration is 2:1.

If hydrogen and Oxygen combine inn 2:2, they for Hydrogen peroxide.

Water gives life and Hydrogen peroxide can kill a person.

Other examples are,

The carbohydrate in food is composed of carbon, hydrogen and oxygen. The stainless steel is made up of iron, carbon and other trace elements. Glass is composed of silicon, oxygen and other elements.

Therefore, only 90 naturally occurring elements capable of combining with each other to form millions of substances.

Determine el número de moles presentes en una esfera de titaniode 0.5 cm de radio, sabiendo que la densidad del titanio es de 4507kg/m³. =433

Answers

Answer:

0.0493 moles de Titanio

Explanation:

Primero, debemos hallar el volumen de la esfera. Usando la densidad podemos hallar la masa de titanio y usando la masa atómica encontraremos las moles de titanio:

Volumen de la esfera:

Volumen esfera = 4/3π * Radio³

Volumen = 0.5236cm³

En m³ (1m³ = 1x10⁶cm³):

0.5236cm³ * (1m³ / 1x10⁶cm³) = 5.36x10⁻⁷m³

Masa en gramos:

5.36x10⁻⁷m³ * (4507kg / m³) = 2.36x10⁻³kg * (1000g / 1kg) = 2.36g de Titanio

Moles -Masa molar Ti: 47.867g/mol-:

2.36g de Titanio * (1mol / 47.867g) =

0.0493 moles de Titanio

A tank for storing liquid as a base of area 1.5 meters square. What is the pressure on the base of the tank when it contains water weighting 4500n

Answers

Answer:

3000 Nm^2

Explanation:

We must remember that pressure is defined as force per unit area.

We have been given the following information in the question;

Area of the tank= 1.5 m^2

Weight of water in the tank = 4500N

And;

P = F/A

F= force

A = area

P = 4500 N/1.5m^2

P= 3000 Nm^2

Which organism in the food chain is
responsible for transforming radiant
energy into chemical energy?

Grass->Prairie Dog -> Coyote -> Soil Bacteria

Answers

Answer:

The organism in the food chain responsible for transforming radiant energy into chemical energy is;

Grass

Explanation:

Radiant energy is the energy present in electromagnetic waves which carry photons that may be considered as energy packets. It is an energy present in the Sunlight, which is an electromagnetic waves, and it is the energy in the electromagnetic waves that plants convert to chemical energy for food in the process known as photosynthesis as follows;

6CO₂ + H₂O + Radiant energy → C₆H₁₂O₆ + 6O₂

Therefore the organism in the food chain responsible for transforming radiant energy into chemical energy is the plant, grass

(2) Far from simply brightening our day, engagement with the natural world through social media may actually be helping to save our planet.(3) Both individuals and organizations increasingly use social media to raise awareness of environmental issues and support conservation research. (4) A research article, news report, or photograph that goes viral can reach a global audience in a matter of minutes, connecting interested people with each other and allowing for a nearly immediate exchange of ideas. (5) In 2012, for example, a high school student posted a picture of an unusual lizard he saw in a local park to a nature-focused social network, where other members identified the lizard and noted how far it was from its known habitat. (6) This in turn became useful data for researchers studying these lizards and their changing ecosystem.(7) The global audience provided by social media can also have a considerable economic impact for environmental causes. (8) Consumer pressure following the viral circulation of photos of turtles and other marine life injured by plastic drinking straws, for example, has led major corporations to seek more environmentally sustainable options. (9) Partly because viral content often makes people get all weepy, social media has also provided powerful fund-raising opportunities. (10) After a video recently circulated showing a rescued chimpanzee who enjoys playing with dolls, online donations to the rescue organization began pouring in.
