Neither

Explanation:

Answer:

elements

Matter that has only one kind of atom is called an element. Gold, copper, oxygen, and mercury are examples of elements. Most matter is made up of two or more different kinds of atoms that are chemically combined. This kind of matter is called a compound.

Explanation:

Answer:

Element

Explanation:

This is the answer because:

1) All matter is made up of substances called elements.

2) Matter that iis made up of only one kind of Atom is called an Element.

Answer:

The main difference between an atom and a molecule lies in the size: while the atom is the smallest unit into which matter can be divided into any of its states, a molecule is the union of a group of atoms, that is, this composed of several atoms. Thus, for example, a water molecule is composed of two hydrogen atoms and one oxygen atom (H2O). Therefore, it can be said that atoms are the smallest unit in which the chemical elements of the world can be divided, while molecules are the particles of matter that are formed through the combination of these elements.

Explanation:

Answer: Carbon Dioxide, Methane, Nitrous Oxide and Fuorinated Gases

Explanation:Carbon dioxide (CO2): Carbon dioxide enters the atmosphere through burning fossil fuels (coal, natural gas, and oil), solid waste, trees and other biological materials, and also as a result of certain chemical reactions (e.g., manufacture of cement). Carbon dioxide is removed from the atmosphere (or "sequestered") when it is absorbed by plants as part of the biological carbon cycle.

Methane (CH4): Methane is emitted during the production and transport of coal, natural gas, and oil. Methane emissions also result from livestock and other agricultural practices and by the decay of organic waste in municipal solid waste landfills.

Nitrous oxide (N2O): Nitrous oxide is emitted during agricultural and industrial activities, combustion of fossil fuels and solid waste, as well as during treatment of wastewater.

Fluorinated gases: Hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride are synthetic, powerful greenhouse gases that are emitted from a variety of industrial processes. Fluorinated gases are sometimes used as substitutes for stratospheric ozone-depleting substances (e.g., chlorofluorocarbons, hydrochlorofluorocarbons, and halons). These gases are typically emitted in smaller quantities, but because they are potent greenhouse gases, they are sometimes referred to as High Global Warming Potential gases ("High GWP gases").

Answer:

Cells are the basic building blocks of living things. The human body is composed of trillions of cells, all with their own specialised function. Cells are the basic structures of all living organisms. Cells provide structure for the body, take in nutrients from food and carry out important functions.

Answer:

we need to know it's

mass and velocity

Explanation:

then use the formula of kinetic energy

Answer:

Mass and velocity (or motion).

Explanation:

KE=(1/2)mv^2.

The kinetic energy of an object is the amount of work (expended energy) that's required to move (or more accurately, to accelerate) the object to a specific velocity.  So, if you know the mass of the object, and you know it's current velocity, you can determine it's kinetic energy with the formula above.

Answer:

Protons, neutrons, and electrons are the three main subatomic particles found in an atom. Protons have a positive (+) charge. An easy way to remember this is to remember that both proton and positive start with the letter "P." Neutrons have no electrical charge.

Answer:

Protons, positive charge

Neutrons, neutral

Electrons, negative charge

Explanation:

The mass, in kg, of Sulfur produced : 2.072 kg

Given

V = 8.56 kL = 8560 L

P = 175 kPa = 1,73 atm

T = 250 + 273 = 523 K

Required

mass of Sulfur produced

Solution

mol of H₂S :

[tex]\tt n=\dfrac{PV}{RT}\\\\n=\dfrac{1.73\times 8560}{0.082\times 523}\\\\n=345.3[/tex]

mol of Sulfur based on mol  H₂S as a limiting reactant( excess Sulfur  dioxide)

From equation, mol ratio  H₂S : S = 16 : 3, so mol S :

[tex]\tt \dfrac{3}{16}\times 345.3=64.74[/tex]

Mass S(Ar = 32 g/mol) :

= mol x Ar s

= 64.74 x 32

= 2071.68 g = 2.072 kg

Answer:

a) silver

Explanation:

Given data:

Mass of object = 26.94 g

Volume of object = 2.568 cm³

Which subject is this = ?

Solution:

Formula:

d = m/v

by putting values

d = 26.94 g/ 2.568 cm³

d =  10.49 g/cm³

Densities of objects: g/cm³

iron =  7.874

gold = 19.32

silver =  10.49

copper = 8.92

Thus, given object is silver.

Explanation:

Carbon-12 and carbon-14 are two isotopes of the element carbon. The difference between carbon-12 and carbon-14 is the number of neutrons in each of their atoms. Atoms of both isotopes of carbon contain 6 protons. Atoms of carbon-12 have 6 neutrons, while atoms of carbon-14 contain 8 neutrons.

Answer:

Hydrosulfuric acid will act as limiting reactant.

Explanation:

Given data:

Mass of iron(III) chloride = 3243.0 g

Mass of hydrosulfuric acid = 511.8 g

Limiting reactant = ?

Solution:

Chemical equation:

2FeCl₃ + 3H₂S       →       Fe₂S₃ + 6HCl

Number of moles of iron(III) chloride:

Number of moles = mass/molar mass

Number of moles = 3243.0 g/ 162.2 g/mol

Number of moles = 20 mol

Number of moles of hydrosulfuric acid:

Number of moles = mass/molar mass

Number of moles = 511.8 g/ 34.1 g/mol

Number of moles = 15 mol

Now we will compare the moles of both reactant with products

                      FeCl₃          :          Fe₂S₃

                       2                :            1

                      20               :          1/2 ×20 = 10

                      FeCl₃          :            HCl

                       2                :              6

                      20               :          6/2 ×20 = 60

                      H₂S             :          Fe₂S₃

                       3                :            1

                      15               :          1/3 ×15 = 5

                      H₂S            :            HCl

                       3                :              6

                      15                :          6/3 ×15 = 30

Hydrosulfuric acid producing less number of moles of product thus, it will act as limiting reactant.
