An atom of gold with 79 protons, 79 Electrons and 118 neutrons would have a mass number of....
A) 39
B) 158
C) 197
D) 276
Answers
Answer:
C
Explanation:
An atom of gold with 79 protons, 79 Electrons and 118 neutrons would have a mass number of 197 gold. Therefore, option C is correct.
What is mass number ?The total number of protons and neutrons in an atomic nucleus is known as the mass number, often known as the atomic mass number or nucleon number. In atomic mass units, it is roughly equivalent to the atom's atomic mass.
Because it indicates the mass of the entire number of protons and neutrons in an element, the mass number of an element is so named. The atomic number and atomic mass of an element are typically listed in periodic tables along with the chemical symbols for each element.
The third element in the periodic table's eleventh column is gold. It is under the transition metal category. The most common isotope of gold has 118 neutrons and 79 protons together with 79 electrons.
Thus, option C is correct.

A space shuttle is covered with two layers of carbon. The two layers are the same size and have the same number of molecules. When the space shuttle is sitting on the ground, the layers do not touch, as shown in the diagram above. When the space shuttle takes off, the layers move so that they are touching. Use the information in the diagram to answer the question.
How does the temperature of the outer layer compare with the temperature of the inner layer before the layers touch? What will happen after the layers have been touching for a while?
Answers
Answer:due to the heat of it the molicules expand and therefor touch also on rentry due to heat
Explanation:
The characteristics of the thermal transfer process allow to find the results for the questions regarding the temperature in the two cases are:
When the material is separated, the transfer is carried out by radiation, the internal temperature rises slowly. When the material is bonded, the heat transfer is carried out by conduction, the interior temperature rises rapidly.
Thermal conduction processes are mechanical by which thermal energy (temperature) is transported, they ask to be of three types:
Conduction. When there is no displacement of matter, the energy is transported by the agitation of the molecules. Convection. When matter is transported, very important for liquids and gases. Radiation. When there is no physical contact and the energy is transferred by the radiation of electromagnetic waves.
At the initial moment the two layers are not touching, therefore the only possible process is radiation, therefore the outermost body may be at a very high temperature and the inner body may be cold since radiation heating is the less efficient.
When the materials touch, the energy transfer process is thermal conduction, therefore the interior temperature will increase significantly. The thermal conduction process is one of the fastest, therefore the temperature rises rapidly.
In conclusion, using the characteristics of the thermal transfer process, we can find the results for the questions regarding temperature in the two cases are:
When the material is separated, the transfer is carried out by radiation, the internal temperature rises slowly. When the material is bonded, the heat transfer is carried out by conduction, the interior temperature rises rapidly.

Laura and Jess observed two points, P and Q, on a number line. A number line is shown from negative 2 to positive 2 with increments of 2 over 8. A point P is shown at the fifth tick mark to the left of 0, and a point Q is shown at the fifth tick mark to the right of 0. Jess said that the absolute values of the numbers represented by the two points are different. Laura said that the absolute values of the numbers represented by the two points are the same. Which of the following explains who is correct?
Jess, because the points are of different signs
Jess, because the points are at different locations
Laura, because the distance between the two points is 10 over 8 units
Laura, because each of the two points is 10 over 8 units from 0
Answers
Answer:
P is 5 ticks to the left of 0, so it would be -5/8
Q is 5 ticks to the right of 0, so it would be at 5/8
an absolute value turns a negative number into a positive number
so absolute value of P located at -5/8 = 5/8
this is the location of point Q
Jimmy said that the absolute values of the numbers represented by the two points are the same.
so Jimmy is correct

How small are the microorganisms that live on and in the human body? Answer it in at least 1 paragraph
Answers
Answer: The human body contains trillions of microorganisms — dwarfing human cells by 10 to 1. Due to their little size, nonetheless, microorganisms make up just around 1 to 3 percent of the weight's (in a 200-pound grown-up, that is 2 to 6 pounds of microscopic organisms), yet assume a crucial function in human wellbeing. In 2016, a survey of over forty years of examination into the human microbiome found that there is zero logical proof to back this frequently refered to tidbit up. Rather, the proportion appears to be about 1.3-to-1, with the normal human playing host to around 100 trillion microorganisms, plus or minus.

What are microorganisms?
Microorganisms are tiny living organisms that can be only seen by microscopes. These organisms are found everywhere on earth. They are free-living and parasitic. There are good and bad microorganisms.
Some are useful to the earth and the living creature, but some are harmful to the health of other living creatures. They are responsible for many diseases in plants, animals, and other organisms.
There are many bacteria present inside the body. They are present in the digestive system, and our mouth. They help in the digestion and breakdown of many food materials and macromolecules.
Thus, the size of microorganisms that are present and live in the human body is 1 to 10 micrometers.

B.) a mixture
C.) a substance
D.) a compound
Answers
According to the forces of attraction, if three different samples of a liquid have different compositions, then the liquid can be classified as a mixture.
What are forces of attraction?Forces of attraction is a force by which atoms in a molecule combine. it is basically an attractive force in nature. It can act between an ion and an atom as well.It varies for different states of matter that is solids, liquids and gases.
The forces of attraction are maximum in solids as the molecules present in solid are tightly held while it is minimum in gases as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.
The physical properties such as melting point, boiling point, density are all dependent on forces of attraction which exists in the substances.
