Physical and Chemical Properties of Magnesium

Here is an EXAMPLE of how it has to be like. Instead of Mercury, you HAVE to do Magnesium

Physical Properties of Mercury: ”I’m a highly stable element, so you can count on me”

Chemical Properties of Mercury: ”I love to travel but I do corrode aluminum so we won’t be flying off on adventures in airplanes planes anytime soon”

Answers

Answer:

Some of the physical and chemical properties of magnesium are:

-The term ‘magnesium’ is derived from the Greek word magnesia, which refers to the name of the place from where it was extracted.

-Magnesium is closely related to manganese and magnetite.

-About 2.1% of the Earth’s crust contains magnesium. This makes magnesium the 6th most found element.

-The biggest deposits of magnesium is found in the seawater. It has been calculated by scientists that a cubic mile of seawater contains about 6 million tons of this element

With radiocarbon dating, scientists compare an object's carbon-14 levels with _____. the carbon-14 levels of an object from the same time period carbon-14 levels in the atmosphere the carbon-14 levels in the rock surrounding the object the object's carbon-12 levels

Answers

Answer:carbon-14 levels in the atmosphere

Explanation:

When carrying out radiocarbon dating, the level of carbon-14 in a sample is compared with the level of carbon 14 in the atmosphere because, objects exchange carbon-14 with the atmosphere.

Comparison of the activities of carbon-14 in the atmosphere and in the sample gives the age of the sample since the half-life of carbon-14 is a constant.

Which statement best supports the idea that water conservation is important for human societies?

OA Once humans use water, it cannot be reused ever again,

OB. Only about 1% of the freshwater on Earth is easily accessible.

OC Water is constantly being lost from the hydrosphere

OD. Most land animals use salt water instead of freshwater.

Answers

Answer:

Only about 1% of the freshwater on Earth is easily accessible.

Explanation:

Freshwater accounts for a minimal proportion of water resources on planet earth. About 70 percent of the world surface area  is covered by water, but only  about 2.5 percent of this mass of water is fresh. The remaining are marine or salt water. Amazingly, just about 1 percent of this  freshwater is easily accessible. The other 1.5% is trapped in glaciers and snowfields.

This underscore the need for water conservation on the planet since fresh water is a scarce resource and people living in many areas have no access to fresh water.

Using the formula M=dx v, Calculate the mass of a liquid with a density of
17.5 g/mL and a volume of 7mL.

Answers

Answer:

The answer is 122.5 g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

volume = 7 mL

density = 17.5 g/mL

We have

mass = 17.5 × 7

We have the final answer as

122.5 g

A ball initially at rest is dropped from a window sill 14.2 m off the ground. Find the velocity of the ball the moment it hits the ground. Round your answer to 2 decimals places.

Answers

Answer:

16.68 m/s

Explanation:

The following data were obtained from the question:

Height (h) = 14.2 m

Initial Velocity (u) = 0 m/s

Final velocity (v) =?

Thus, the velocity (v) with which the ball hit the ground can be obtained as follow:

v² = u² + 2gh

NOTE: the acceleration due to gravity (g) = 9.8 m/s²

v² = u² + 2gh

v² = 0² + 2 × 9.8 × 14.2

v² = 0 + 278.32

v² = 278.32

Take the square root of both side

v = √278.32

v = 16.68 m/s

Therefore, the velocity with which the ball hit the ground is 16.68 m/s

The discovery of optics gave scientists instruments such as microscopes and telescopes.

Explanation:

The period between the 16th-8th century was called the period of the scientific revolution. At this time, the foundations  of our modern science was laid.

One of the characteristic of this period was the emphasis on the scientific method which upheld results from reproducible experiments.

Nicolaus Copernicus, Francis Bacon and Isaac Newton were leading names in this period.

It was within this period that the discovery of optics gave scientists instruments such as microscopes and telescopes and scientific  examination of the celestial bodies was launched.
