Answer:

Heavy elements are created by fusing two elements together in a lab. They look for “events” that comprise a series of alpha decays that result in spontaneous fission.

Explanation:

Atoms of different element can not have same atomic number because only same type of atoms combine to form element. Atoms belonging to different element can have different atomic number. Therefore, in below given ways we can summarize how heavy elements are created.

Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.

Elements heavier than iron cannot be created by fusion because the reaction requires energy to occur. We do, however, perceive elements other than iron all around us. This is accomplished by supernova explosions, which result in neutron capture processes and the production of heavy materials.

Therefore, in above ways we can summarize how heavy elements are created.

Answer:

Dihydrogen Dioxide

The name of binary molecule H₂O₂ is also known as hydrogen peroxide and is a popular disinfectant for cuts or scrapes is dihydrogen dioxide. The correct option is A.

Dihydrogen dioxide is the substance of water with extra oxygen molecules. In the dihydrogen monoxide parody, water is referred to by a strange scientific term, most frequently "dihydrogen monoxide,". It is a poisonous gas, and it is leading to the death of many people in America. It is known as DHMO.

Some of its characteristics are listed in an especially ominous manner, such as speeding up corrosion and inducing asphyxia. This substance, commonly referred to as hydrogen peroxide, is used frequently as a disinfectant for cuts and scrapes.

Thus, the correct option is A. Dihydrogen dioxide.

Answer:

It represents the relationship between the distance travelled and time spent as constant or at a stop.

Explanation:

This is because as the line progresses, the time increases the distance should change as well my moving up or down, in a linear equation this relationship is constand but if the line is horizontal though, the distance is not changing despite time passing which means it has come to a stop.

Explanation:

Percent Error = measured value - accepted value/ accepted value x 100

Measured Value: 15.78

Accepted Value: 16.00

Work:

[tex]\frac{15.78-16.00}{16.00}[/tex] * 100

Explanation:

Mass is the most basic property of matter and it is one of the fundamental quantities. Mass is defined as the amount of matter present in a body. The SI unit of mass is the kilogram (kg). The formula of mass can be written as:

Mass = Density × Volume

The mass of a body is constant; it doesn’t change at any time. Only in certain extreme cases when a huge amount of energy is given or taken from a body, the mass may be impacted. For example, in a nuclear reaction, a tiny amount of matter is converted into a huge amount of energy, this reduces the mass of the substance.

There are various units for calculating mass, like, kilograms, grams, lbs, pounds, etc., but the SI unit of mass is "kilograms" or kg. Every unit of mass can be converted to other units by using a proper conversion formula without affecting the meaning and essence of the quantity to be measured.

Answer:

9.012182 u

Explanation:

Explanation:

Relative molecular mass of CH4 = 12 * 1 + 4 = 16

Relative molecular mass of SO2 = 32 + 10 *2 = 64

tSO2/tCH4 = √MSO2/MCH4

t/20 = √64/16 = √4

t/20 = 2

∴ t = 20 * 2 = 40sec
