Explanation:

Genetic mutation refers to the changes in the arrangement of the bases that make up a gene. This sudden change may have positive or negative consequences for the individual specie.

Some genetic mutations actually alter a gene's sequence of bases but do not alter the function of the particular protein that the gene in question makes.

The two options chosen in the answer shows situations in which a genetic mutation causes harm to the organism involved.

Explanation:

A boulder sits at rest on top of a mountain. What conclusion can be made about the forces acting on the boulder? The forces acting on the boulder are balanced (net force equals zero).

If a boulder sits at rest on the top of the mountain , the forces acting on the boulder are zero as it is in the state of rest.

Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.

It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.

The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.

Answer:

There are  there are 8.13-10^25

Explanation:

N(CS2)= 1.35* (times) 6.02-10^ 25= 3.13-10^25 molecules

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 8.12×10²³ molecules are in 1.35 mole of CS[tex]_2[/tex].

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity of amount of substance. It measure the number of elementary entities of a given substance that are present in a given sample. There are so many formula for calculating mole.

we know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number

number of atoms/molecules=number of moles × 6.022×10²³(Avogadro number)

number of moles of CS[tex]_2[/tex] =  1.35 mol

Substituting all the given values in the above equation, we get

number of atoms/molecules= 1.35 × 6.022×10²³

number of atoms/molecules=8.12×10²³ molecules

Therefore, 8.12×10²³ molecules are in 1.35 mole of CS[tex]_2[/tex].

The end product of the decay of uranium 238 is Pb-206.

Heavy elements are generally grouped into four decay series which are; Thorium series, Uranium series and actinium series and Neptunium series.

These heavy elements decay via a series of α and β emissions until a stable nucleus is finally achieved. All these decay series usually terminate in a lead nucleus.

Uranium 238 belongs to the uranium decay series and terminates at Pb-206.

Answer:differentiate between two compounds i think!

Explanation: taking a test!

Answer:(1) differentiate between two compounds

Explanation:

A Chemical property tells us the  characteristics of a particular matter or substance after a  chemical change. This property helps us to differentiate a compound from another or differentiate   elements or substances. Examples of a Chemical property are  acidity, reactivity and heat, etc .

For example to differentiate between Water H2O and  Hydrogen peroxide, H202

Even though they are made up of  oxygen and hydrogen. Hydrogen peroxide  (H2O2), has  more(1) oxygen than water (H2O).

Using Acidity as a chemical property to differentiate these substances

Water, H20  is amphoteric in nature ie having both acidic and basic properties, while H202 is a weak acid.

Answer:

Elements that are metals tend to lose electrons and become positively charged ions called cations.

Elements that are nonmetals tend to gain electrons and become negatively charged ions called anions.

Hope it helps:)

Metal are the  family of elements which is most likely to lose electrons. Non metals are the  family of elements which is most likely to gain electrons.

The quantity of protons an element has defines it. An element's atoms all contain the same amount of protons, but its electron and neutron counts might vary. Ions are produced by altering the electron to proton ratio, whereas isotopes are produced by altering the neutron count.

118 known elements are present. A study is being done to create element 120.1. The periodic table will have to be modified to include element 120 after it has been created and validated. Metal are the  family of elements which is most likely to lose electrons.

Therefore,  metal are the  family of elements which is most likely to lose electrons.

Answer:

From 4.9 g of sulfuric acid 8.175 g of potassium sulfate is formed.

Explanation:

Given data:

Mass of H₂SO₄ = 4.9 g

Mass of K₂SO₄ formed = ?

Solution:

Chemical reaction:

H₂SO₄ + 2KOH    →    K₂SO₄ + 2H₂O

Number of moles of H₂SO₄:

Number of moles = mass/ molar mass

Number of moles = 4.9 g/ 98.1 g/mol

Number of moles = 0.05 mol

Now we will compare the moles of  H₂SO₄ with  K₂SO₄ .

                       H₂SO₄         :             K₂SO₄

                            1             :                  1

                       0.05           :             0.05

Mass of K₂SO₄:

Mass = number of moles × molar mass

Mass = 0.05 mol × 174.3 g/mol

Mass = 8.715 g

Thus, from 4.9 g of sulfuric acid 8.175 g of potassium sulfate is formed.
