Answer:

The given sample is aluminum.

Explanation:

Given data:

Mass of unknown sample = 54 g

Volume of given sample = 20cm³

Is sample is Al = ?

Solution:

In order to solve this problem we must know the density of Al from literature.

density of Al = 2.7 g/cm³

Now we will calculate the density of given unknown sample.

d = m/v

d = 54 g/  20cm³

d = 2.7 g/cm³

Thus given sample is aluminum.

Right from the start, you know that you're indeed dealing with a neutral atom, since the number of protons it has in its nucleus is equal to the number of electrons it has surrounding its nucleus.

Now, an atom's atomic number,  

Z

, tells you how many protons it has in its nucleus. Nothing more, nothing less.

In your case, you are told that the atom contains  

16

protons in its nucleus, which means that  

Z

will be equal to

A quick look in the periodic table will reveal that you're dealing with an atom of sulfur,

Black holes are so dense that light cannot escape from them, and they are difficult to detect. Satellites above the Earth's atmosphere can detect bursts of high energy radiation given off by black holes. Dozens of stellar black holes have already been detected in the Milky Way, where there may be tens of millions more.

Explanation:

Answer:

B)

Explanation:

Answer: When we represent a chemical reaction in terms of words, we write a word equation. For example, when hydrogen gas reacts with oxygen gas to form water, we can write a word equation for the reaction as follows: hydrogen + oxygen→ water To the left of the arrow, we have the 'before' situation.

Is there a question you need help with?

Answer:

Option A. Na⁺

Explanation:

Floride ion (F¯) simply indicates that the fluorine atom has gain an extra electron.

Thus, the electronic configuration of the fluoride ion (F¯) can be written as follow:

F¯ (10) => 1s² 2s²2p⁶

Next, we shall determine the electronic configuration of the element given in options to see which is the same as that of the fluoride ion (F¯). This is illustrated below:

Na⁺ (10) => 1s² 2s²2p⁶

Na (11) => 1s² 2s²2p⁶ 3s¹

Cl (17) => 1s² 2s²2p⁶ 3s²3p⁵

Cl¯ (18) => 1s² 2s²2p⁶ 3s²3p⁶

From the above illustrations, we can see that the fluoride ion (F¯) has the same electronic configuration as Na⁺.

Each element is made up of electrons and these electrons are filled in different shells. These are the following shells in the electrons:

According to the question, the fluoride ion has 10 electrons in its 2 shells, that is 2 in K shell and 8 in L shell.

A similar number of shell and electrons to the fluoride ion is sodium ion ([tex]Na^{+}[/tex])

The [tex]Na^+[/tex]has a total 10 number of electrons, hence the electronic configuration is 2 and 8.

Therefore, the [tex]Na^+[/tex] is the correct option.

Answer:

Explanation:

The atomic number (number at the top) is the amount of protons and the amount of electrons. So if an element has an atomic number of 5, you know that it has 5 protons and 5 electrons. The atomic mass (number at the bottom) is the amount of protons and neutrons added together.

Monosaccharides are the most basic units of carbohydrates. These are simple sugars, including glucose, fructose, and others. They contain between three and seven carbon atoms, have a sweet taste and are used by the body for energy.

The metric system is used to measure the objects based on various parameters. A centimeter is a unit of length. One inch is equivalent to 2.54 cms.

The Metric system is the system used to estimate the weight (mass), length, and capacity of the object and was first introduced in France by  Gabriel Mouton, a mathematician, and an astronomer. The metric system measures length, mass, volume, time, etc.

The metric system of length use the SI unit of meter, other units used to measure the length are centimeter, kilometer, millimeter, inches, yard, mile, feet, etc.

Given,

Length = 1 inch

It is known that an inch is equivalent to 2.54 centimeters, hence, 1 cm = 2.54 cms.

Therefore, there are 2.54 centimeters in one inch of the object.
