How is mass measured? What are standard units used to measure mass?
Answer: Mass in an object is often weighed on a scale. The standard units used to measure mass are the grams (g) and kilogram (kg).
Answer:
The basic SI unit of mass is the kilogram(kg). In physics mass is not the same as weight even though mass is determine by measuring the object's weight using spring scale rather than balance scale comparing it directly with known masses..

On a number line, suppose the coordinate of A is 0, and ARequals5. What are the possible coordinates of the midpoint of AR overbar? The possible coordinates for midpoints of the segment are nothing. (Type integers or decimals. Use a comma to separate answers as needed.)
Answer:
2.5, - 2.5
Explanation:
Given that :
Coordinate of A = 0
and AR = 5 ; distance between A and R
Possible. Coordinate of the midpoint of AR overbar.
Hence for a distance of 5 points between A and R, then R may be located 5 points either side of A, that is to the left of right.

If A + B → C + D You start with 50 g of A and 30 g of B and 40 g of C are produced, how many g of D would also be produced?
Answer:40g of D
Explanation:
Law of conservation of matter:
Matter can neither be created nor be destroyed but can change from one form to another.
The total of the reactants must be equal to that of the product.
A+B=>C+D
50g+30=40g+D
80g=40g+D
D=80-40
D=40g

B.It is the sum of internal energies of two or more substances.
C.It is the portion of internal energy that can be transferred from one substance to another.
D.It is the portion of potential energy that can be transferred from one substance to another.
Answer:
Tha answer I s D. Hope it will work to u
Thermal energy is the difference between internal energies of two or more substances. Therefore, option A is correct.
What is thermal energy ?The energy present in a system that determines its temperature is referred to as thermal energy. Thermal energy flows as heat. Thermodynamics is a whole field of physics that studies how heat is transmitted across various systems and how work is done in the process.
The average kinetic energy of the system's component particles as a result of their motion makes up the thermal energy of the system. The sum of the kinetic and potential energies of the system's component particles represents the system's overall internal energy.
Thermal energy is also referred to as heat energy. A moving object's kinetic energy is its energy. Thermal energy is a type of kinetic energy because it is produced by moving particles.
Thus, option A is correct.

A solution contains 90 mL of methanol, 18 mL of propanol, and 2 mL of diethyl ether. Which is the solvent in this solution
solution?
O methanol
O propanol
O diethyl ether
O water
Answer:
Methanol
Explanation:
The solvent in this solution is methanol
What is Solvent?Solvent is a substance in which the solute is dissolved.polar and non polar are two types of solvent.
What are Polar solvents and Non Polar solvents?A solvent which has dipole moments are known as polar solvents.A polar solvent can dissolve ions and other polar compounds.A non polar solvent is a solvent which does not have dipole moments.
What is solute?A substance that dissolves in solution is called solute.When two liquids are mixed to form a solution, the solute is the species that is present in the smaller ratio.
Why Methanol is the solvent in this solution?Methanol is the component that has the greatest volume compared to other solvents. It means that it is found in a greater proportion. So methanol is the solvent in this solution.
Hence the other options are incorrect.

Ne - 1s² 2s² 2p⁶
pls give me brainliest!!!
The electronic configuration of the first ten elements are as follows:
H → 1s¹
He → 1s²
Li → 1s² 2s¹
Be → 1s² 2s²
B → 1s² 2s² 2p¹
C → 1s² 2s² 2p²
N → 1s² 2s² 2p³
O → 1s² 2s² 2p⁴
F → 1s² 2s² 2p⁵
Ne → 1s² 2s² 2p⁶
Elements are named according to there atomic number in the periodic table.
The number of electron in an electronically neutral atom is equals to the number of protons.
The number of protons is also the atomic number of that element.
The first ten elements are Hydrogen, Helium, lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Fluorine and Neon.
The electronic configuration of elements is base on the number of electrons.

Can someone give me an explanation about the location of the protons, neutrons, electrons in the atom
There are two main areas of an atom, the electron cloud and the nucleus
First, let's talk about the atom's nucleus. The nucleus is in the middle of the atom. The nucleus contains neutrons (particles with no charge) and protons (positively charged protons). The number of protons is constant in every atom of the same element, meanwhile the number of neutrons is not. The atomic number of an element describes the amount of protons in a atom of that same element and it is fixed.
The electron cloud, on the other hand, is a predicted zone that's used to roughly estimate where the electrons are within the atom. Electrons are said to have no fixed orbit.

Explain why the boiling point of ethanol is higher than that of hexane
(Relative molecular mass of ethanol is 46 while that of hexane is 86)
The boiling point of ethanol is higher than hexane as ethanol has the presence of strong intermolecular forces.
The boiling point has been the temperature required by the substances for converting from liquids to gases. The boiling point of a substance has been based on the intermolecular forces present in the compound.
The stronger the intermolecular force, the higher will be the energy required for the conversion of the body, and the higher will be the boiling point.
The intermolecular force present in the hexane is hydrogen bonding. The force present in ethanol has been a strong van der wall force with hydrogen bonding.
The intermolecular force in ethanol is stronger than the hexane, thus ethanol has a higher boiling point than hexane.

What is the wavelength of waves that have a frequency of 2.20 x 10 −4 Hz
Answer:
1.36 x 10^12 m
Explanation:
This is because the equation for wavelength is a modification of c = λf.
c is the speed of light, which is 3.00 x 10^8 m/s
2.20 x 10^-4 Hz is the frequency (f)
so to find λ, which is the wavelength, you would have to divide c by f. You would write it out like 3.00 x 10^8 m/s divided by 2.20 x 10^-4 1/s (Hz is a unit whose time is measured in seconds). The s would cancel out, you would divide 3.00 by 2.20, and you would apply the rule of exponents to the 10^8 power divided by 10^-4 for 10^12 power because the -4 is the denominator, and because it is negative, instead of subtracting the exponent you would add it
