Each species is a separate type of organism.
A species is a group of creatures that share similar traits. The same species of organisms are capable of sexual reproduction as well as interbreeding and producing fertile offspring. It is a fundamental unit of taxonomy and classification.The system is divided into seven categories: Kingdom, Phylum or Division, Class, Order, Family, Genus, and Species. Kingdom is the most inclusive category.In a group, many types of an organism can be included even if they do not share the same traits. But species is a group of organisms that share similar traits.For example, human beings are species as they are all alike in physical features, way of reproduction, etc. But the animal is considered a group because it included a variety of living beings.Therefore, Each species is not considered a group.

Why is isopropyl alcohol a pure substance?
Answer:
A substance is considered a chemically pure substance when it has a fixed chemical composition throughout, and uniform physical and chemical properties. Because isopropyl alcohol ( C3H8O ) Is a homogenous compound with constant physical and chemical properties, as well as a uniform chemical structure, isopropyl alcohol is definitely fit to be considered a pure substance.

0.05016 grams is there if you have 2.85x10^-4 with 176g/mol.
The mass of a certain molecule is its molecular mass, which is expressed in daltons. Because they contain various isotopes of an element, multiple molecules of the same substance can have distinct molecular weights.
mole = 2.85x10^-4
mol. weight = 176g/mol
Formula,
mole = weight taken / mol. wt of the compound
2.85x10^-4 = weight taken / 176g/mol

According to Newton's law of universal gravitation, what is the effect of gravity on two objects as the distance between them increases?
OA. The force of gravity increases.
OB. The force increases by twice the previous amount.
OC. There is no effect on the force of gravity.
O D. The force of gravity decreases.
Answer:
Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
Answer:
The force of gravity decreases.

what distance in miles can you drive in your new Prius hybrid, if your car gets 56 miles per gallon and you have 15.5 gallons of gas?
Taking into account the rule of three, you can drive your new Prius hybrid a distance of 868 miles.
Rule of threeRule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.
If the relationship between the magnitudes is direct, the direct rule of three must be applied as follow, being a, b and c known data and x the variable to be calculated:
a ⇒ b
c ⇒ x
So: x= (c×b) ÷a
Distance in miles in this caseIn this case, you can apply the following rule of three: If the car for 1 gallon of gasoline gets 56 miles, for 15.5 gallons of gasoline it gets how many miles?
1 gallon ⇒ 56 miles
15.5 gallons ⇒ x
So: x= (15.5 gallons ×56 miles) ÷1 gallon
Solving:
x= 868 miles
In summary, you can drive your new Prius hybrid a distance of 868 miles.

the mass of the new solid substance increases because a substance in the gas state has mass and contributes
to the new substance's mass.
the mass of the new solid substance does not change because a substance in the gas state does not have

it is difficult to determine if the new substance will increase in mass because it depends on the type of gas.
According to the law of conservation of mass, if a chemical reaction occurs and a solid reacts with a gas to form a new solid: (a) the mass of the new solid substance increases because a substance in the gas state has mass and contributes to the new substance's mass.
Law of conservation of mass states that, the mass can neither be created nor be destroyed in a chemical reaction, it can only be transferred rom one form to another or from the reactants to the products of a chemical reaction.

Answer:
Personally I think thatthr answer could be 5.38853503%, you can round it however you need.
Explanation:
There's a value of error between the noted square meters and the actual room's area. which is 4.23. Using the formula to get the percentage of error is getting the value (78.5 - 74.27 = 4.23) and dividing it by 78.5. Then just multiply it by 100 to get the percentage.
A nugget of gold occupies 5.64 mL of water and weighs 108.8521g. Its density is
The density of a nugget of gold which occupies 5.64 ml of water and weighs 108.85 g is 19.29 g/cm^3.
The density of a gold nugget can be calculated by using the following formula:
Density of nugget = Mass of gold nugget/Volume occupied by gold nugget
Here,
the mass of gold is given to be 108.85 grams and the volume occupied by gold is given to be 5.64 ml or 5.64 cm^3.
Putting these values in the above equation
Density = 108.85 g / 5.64 cm^3
Density = 19.29 g/cm^3
Thus, the density of a nugget of gold which occupies 5.64 ml of water and weighs 108.85 g is 19.29 g/cm^3.

If the oxide contains 22.24 % O by mass, what is the identity of the metal?
Express your answer as a chemical symbol.
The oxide contains 22.24% O by mass, so the identity of the metal as a chemical symbol is lead (Pb).
What is metal?A substance with high electrical conductivity, luster, and malleability, which readily loses electrons to form positive ions (cations) are called metals.
Mass percentage of oxygen in the oxide, i.e.,
ω(O) divided by 100 ω(O)
=22.24% ÷ 100%.
Mass percentage of oxygen in the oxide, i.e .ω(O) = 0.2224
Now the mass percentage of oxygen in the oxide multiplied by 100 ten we get the mass of oxygen in the oxide. If we take 100 grams of compound:
1) m(O) = ω(O) * 100 g.
Mass of oxygen in the oxide, i.e. m(O) = 0.2224 * 100 g.
Mass of oxygen in the oxide. i.e., m(O) =22.24g
Amount of oxygen, i.e.,
n(O) = mass of oxygen in the oxide ÷ molar mass of oxygen.
n(O) = m(O) ÷ M(O) amount of oxygen
n(O) = 22.24g ÷ 16 g/mol,
amount of oxygen i.e. n(O) = 1.39 mol
Mass of metal in the oxide, i.e., m(M) = 100 g - 22.24 g.
Mass of metal in the oxide i.e., m(M) = 77.76g
Now we to find the molar mass of metal oxide,
Molar mass of the metal :
= mass of metal in the oxide ÷ amount of oxygen(M)
= m(M) ÷ n(M). M(M)
= 77.76 g ÷ 1.39 mol.
Molar mass of the metal will be 5.94 g/mol.
Therefore, The identity of the metal is lead (Pb).

Phase Transition:
The three main states of matter are Solid, Liquid, and gas. A phase transition occurs from one state of matter to another when energy is supplied or cut.When energy is supplied to the molecules, solid converts to liquid, and liquid converts to gas. Then, the energy increases the speed of the molecules, the density decreases and phase transition takes place.On the other hand, when the supply of energy is stopped from the molecules, the gas turns to liquid, and liquid converts to solid. Both the temperature and pressure are in the same phase.Therefore, there will be no phase transition in the sample. Hence, it is a true statement.
