Answer:
Density
Explanation:
The ratio of mass to the volume of an object is called its density. Unit of mass is grams and that of volume is mL.
Density = mass/volume
[tex]\text{Density}=\dfrac{\text{grams}}{\text{mL}}\\\\=\text{grams/mL}[/tex]
If you are calculating the grams to mL ratio, it means that we are trying to find the object's density.
Based on these footprints, you decide that the organism started to run.

What happens immediatesly after you dissolve acid in water? Positively charged hydrogen atoms are released. Positively charged hydrogen atoms are released. Negatively charged hydrogen atoms are released. Negatively charged hydrogen atoms are released. Hydronium ions are released. Hydronium ions are released. Neutrally charged hydrogen atoms are released. Neutrally charged hydrogen atoms are released.
Answer:
The correct answer is A.
Explanation:
The acids with hydrogen atoms in them are the ones that dissolve best in water and when they do, they get diluted, raising their pH level by releasing hydrogen ions (H+) into the solutions.
So when acids get dissolved in water, positively charged hydrogen atoms are released.
The answer is A.

Placing a sample of iron (II) oxide into a graduated cylinder makes the water volume increase 12.0 ml. The weight of the sample is 76.6g. What is it’s density? (Round to the nearest hundredths)
Answer:
The answer is 6.83 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass of iron (II) oxide = 76.6 g
volume = 12 mL

what does it mean when you hear science is tentative?
Answer/Explanation:
Tentative means that something is uncertain. So if some aspect of science is described as "tentative" it probably means that there is some evidence to support a hypothesis, but there is more work to be done to be sure about the statements being made.
You may also see these reports described as "preliminary", as they are acknowledging the work is not complete

Which of the subatomic particles are responsible for the differences in isotopes?
Protons
Electrons
Atoms
Neutrons
Answer: Neutrons
Explanation:
Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.
Answer:
neutrons
Explanation:
isotopes has the same proton number but different nucleon number because there's different numbers of neutrons in isotopes
Which mineral is soft enough to be scratched by a fingernail?
a)
corundum
b)
calcite
c)
talc
d)
topaz
Answer:
Talc
Explanation:
Talc only has a hardness of one on the Moh's scale of hardness. This translates into a very soft material, which results from its layered nature. Naturally, this substance is hydrophobic (dislikes water), and tends not to absorb water, therefore giving some of its favourable water-resistant characteristics.
How many neon atoms are in 2.7 moles of neon ?
Answer:
2.7 moles of neon contain 16.3 × 10²³ atoms of neon.
Explanation:
Given data:
Number of moles of neon = 2.7 mol
Number of atoms of neon = ?
Solution:
We will use using Avogadro number to solve given problem.
"It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance"
The number 6.022 × 10²³ is called Avogadro number.
1 mole of neon = 6.022 × 10²³ atoms of neon
2.7 mole of neon × 6.022 × 10²³ atoms of neon / 1 mole of neon
16.3 × 10²³ atoms of neon
Thus, 2.7 moles of neon contain 16.3 × 10²³ atoms of neon.

arrange 0.35 kilograms 9.4 grams and 5 grams to smallest to largest
Answer:
5 grams < 9.4 grams < 0.35 kilograms
Explanation:
Kilograms (Kg) and grams (g) are both units of measurement for MASS quantity. However, these units are not the same as they vary in magnitude. The kilograms is bigger unit of measurement than the grams. 1000grams makes 1kilograms.
According to this question, 0.35 kilograms 9.4 grams and 5 grams are to be arranged in ascending order i.e. from smallest to largest. First, we need to change all the units to the same.
We change 0.35kg to g
Since 1000g = 1kg
Then, 0.35kg = 0.35 × 1000
= 350g.
Rearranging the values, we have:
5 grams < 9.4 grams < 0.35 kilograms
Which of the following can be inferred from the diagram above that shows the dependence of potential Energy on the Internuclear distance between two atoms?
A - The atoms form a bond with a bond length of 25 pm
B - The atoms form a bond with a bond length of 75 pm
с - The net force between the atoms is attractive at 25 pm
D - The net force between the atoms is attractive at 75 pm
Answer:
B - The atoms form a bond with a bond length of 75 pm
From the potential energy diagram of shown, we can infer that the atoms form a bond with a bond length of 75 pm.
When atoms are far away from each other, there exists no interaction whatsoever between the atoms.
However, as the atoms draw closer to each other, the potential energy diagram begins to shift towards an energy minima as we can see from the potential energy diagram.
As the system continues to tend towards this minima, the distance between the atoms decreases. The distance at which the two atoms have the lowest energy is called the bond length.
For this system, such a bond length occurs at 75pm as we can see from the diagram.

what other substances are considered pure substances
Explanation:
B and C they are the pure substances
Elements are considered as pure substances . Elements are mostly metals, non - metals and metalloids , so option C is right.
What are Elements ?An element is a substance that cannot be broken down by non - nuclear reaction. Elements considered as a pure substance . All elements are mostly pure substances. A few of them include gold, copper, oxygen, chlorine, diamond, etc. Compounds such as water, salt or crystals, baking soda amongst others are also grouped as pure substances.
An element is a fundamental item that cannot be easily broken in smaller pieces. There are about 100 elements ,each with it's own types of atom. Everything in universe contain an atom of at least on or more than one elements.
Elements are pure substances ,hence option C is correct.

Which of the following does not affect the gravitational force
between the earth and the sun
A
The mass of the earth
B
The mass of the sun
с
The distance between the earth and the sun
D
The net electrical charge of the earth
Answer:
D. The net electrical charge of the Earth.
Explanation:
I remember from middle school. The other three options affect the gravitational force.
The gravitational force between the earth and the sun is dependent on the mass of these two objects as well as the distance between the earth and the sun. Thus, option D is the correct answer.
Why is gravitational pull important?Gravitational pull is referred as a force of attraction beared by the planetary objects. Gravity is responsible for the revolution of planets around the sun in their fixed orbits.
Gravitational pull is important as it keeps the earth revolving around the sun from a safe distance. It holds the earth in position and thus supports the life on earth. Gravity is responsible for optimum atmosphere on earth.
The formation of celestial bodies is also under the influence of gravitational pull. Gravitational force thus is consired as a fundamental force that govers all the celestial bodies.
Gravitational pull is therefore important for the life on earth.
