Answer:
object's inertial property
Explanation:
The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.

The chemical equation describing the burning of hydrogen gas is: 2H2 + O2 ---> 2H2O.
Why is this both a synthesis and a combustion reaction?
Answer:
"A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. Combustion reactions must involve O2 as one reactant. The combustion of hydrogen gas produces water vapor." and "A synthesis reaction occurs when two or more reactants combine to form a single product. ... In a double replacement reaction, two compounds exchange elements. A combustion reaction occurs when a substance reacts quickly with oxygen. Combustion is commonly called burning"

12) Which model of the atom is thought to be true?
a. Protons, electrons, and neutrons are evenly distributed throughout the volume of
the atom.
b. The nucleus is made of protons, electrons, and neutrons.
c. Electrons are distributed around the nucleus and occupy almost all the volume of
the atom.
d. The nucleus is made of electrons and protons.
Answer:
B
Explanation:
The neucles is surrounded by electrons. Electrons occupy most of the volume of the atom.
Atomic Model:
Atoms are the smallest unit of elements, which form bonds with others. In an atom, electrons revolve around the nucleus.
The nucleus is composed of positively charged protons and neutrons. The nucleus occupies a very small part of the atom.
Electrons are negatively charged particles, they are found around the nucleus and occupy most of the part of the atom.
Therefore, The neucles is surrounded by electrons. Electrons occupy most of the volume of the atom.

Provide your answer in the following format: [element name], [chemical family]
Answer: Bismuth (Bi) , Nitrogen family
Explanation:
As the element has 5 valence electrons in the sixth energy level, which mens it belongs to 6th period as the valence electron has entered the 6th energy level.
Now as the electrons are filled according to afbau's rule , the electronic configuration of the element will be :
[tex][Xe]4f^{14}5d^{10}6s^26p^3[/tex]
Now as the atomic number of element is equal to the number of electrons in a neutral atom , the atomic number is 83 and the element is Bismuth (Bi). As the last electron enters p -subshell , it is a p block element. It lies in group 15 which is nitrogen family.

Based on the chemical formula and state of matter, which of these substances will conduct electricity?
CuSO4(s)
CuSO4(aq)
C5H12(l)
CO2(g)
Answer:
CuSO4(aq)
Explanation:
The aqueous form of copper sulfate will conduct electricity.
The Solid form will not be a good conductor.
C₅H₁₂ will not conduct electricity
CO₂ will not conduct electricity
Copper sulfate is an ionic compoundIn aqueous solutions or molten forms, ionic compounds can conduct an electric current using free mobile ions as carriers. This way, they are electrolytes. In solid state, the ions are arranged into a crystal lattice and will not conduct a current of electricity.Wax melts when it is heated. Which most likely describes what is true of the result of this reaction?
The bonding of the atoms is not the same before and after the change.
The wax has the same density before and after the change.
The same amount of wax exists before and after the change.
The wax cannot be changed back into a solid.
quickly help!!!
Answer:
The same amount of wax exists before and after the change.
Explanation:
Answer:
c -the same amount of wax exists before and after the change-
Explanation:
I did the quiz (edg.) :)
Some notes for you:
A physical change is a change in some of the physical properties of matter, but not in its identity.Wax melting is an energy change, and the energy change can be reversed, which means the wax cools into hard wax again. The wax didn't leave, nor did it somehow get less of it. It stays the same! :)I hope you have an amazing day, I mean it. God bless you!

Which of the following equations of CH4 + Cl2
-
CCl4+ HCl is balanced?
A. O CH4 + Cl2 - CC14+ HCI
B.
CH4 + Cl2 - CCl4 + 4HCI
С.
CH4 + 4Cl2 - CCl4 + 4HCI
D
CH4 + 2Cl2 - CCl4 +2HCI
Balanced equation : C. CH₄ + 4Cl₂⇒ CCl₄+ 4HCl
Further explanationEqualization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:
1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.
2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product
3. Select the coefficient of the substance with the most complex chemical formula equal to 1
Reaction
CH₄ + Cl₂⇒ CCl₄+ HCl
Give coefficient :aCH₄ + bCl₂⇒ CCl₄+ cHCl
Make equation :C, left=a, right=1⇒a=1
H, left=4a, right=c⇒4a=c⇒4.1=c⇒c=4
Cl, left=2b, right=4+c⇒2b=4+c⇒2b=4+4⇒2b=8⇒b=4
The equation becomes :
CH₄ + 4Cl₂⇒ CCl₄+ 4HCl

how can you tell if an element has been reduced?
Answer:
Chemists keep track of how electrons are transferred between atoms in a reaction using an oxidation number. If the oxidation number of an element in the reaction increases or becomes less negative, the element has been oxidized, while a decreased or more negative oxidation number means the element has been reduced.

It has more electrons in the product than in the reactant

Answer:
0.86 moles of CO₂
Explanation:
Given data:
Number of atoms of CO₂ = 5.2×10²³ atom
Number of moles = ?
Solution:
Avogadro number:
The given problem will solve by using Avogadro number.
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 = 6.022 × 10²³ atoms
5.2×10²³ atom× 1 mol / 6.022 × 10²³ atoms
0.86 mol

Impurities that evaporate easily and travel with the water vapor are not removed when using this type of distillation. Explain the reason for this.
Answer:
Please add as brainlist
Explanation:
Distillation is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components in the mixture. In either case, the process exploits differences in the relative volatility of the mixture's components. In industrial applications, distillation is a unit operation of practically universal importance, but it is a physical separation process, not a chemical reaction.
