She remembered that chemical equations can summarize what happens in a chemical reaction. What is the name of the two parts found on the left side of the equation below? 4 Fe + 3O2 → 2Fe2O3 A. products B. reactants C. scientific notation D. synthesis
Answer:
The name of the two parts found on the left side of the equation is reactants.
Explanation:
Chemical reaction is the way one substance reacts against another. That is, a chemical reaction is that chemical process in which two or more substances, by the action of an energy factor, are converted into other substances. The new substance (s) that are formed usually present a totally different appearance from that of the starting substances.
In a chemical reaction there are the substances that react, that is, the reactants, and the substances produced, called products.
A chemical reaction is represented by a chemical equation. The formulas of the reactants are written on the left, and those of the products on the right, both separated by an arrow indicating the direction of the reaction.
Reactants ⇒ Products
Then, the name of the two parts found on the left side of the equation is reactants.

[2nd Row L-R] - Force, Ionic, Covalent
[3rd Row L-R] - Atoms, Lost or Gained, Shared
[4th Row L-R] - More stable, Metal and Nonmetal, Nonmetal and Nonmetal
Explanation:
Chemical bonds are a force that hold together atoms in a substance to make compounds more stable.
Chemical bonds include two kinds: Ionic and Covalent.
Ionic in which electrons are lost or gained where attraction is between a Metal and Nonmetal.
Covalent in which electrons are shared where attraction is between a nonmetal and nonmetal.

what volume of water has a mass of 1 kg
Answer:
[tex]V=0.001\ m^3[/tex]
Explanation:
Mass, m = 1 kg
The density of water, d = 1000 kg/m³
We need to find the volume of water. The formula for the density of an object is equal to mass divided by volume. Its formula is :
d = m/V
V is the volume of water
[tex]V=\dfrac{m}{d}\\\\V=\dfrac{1\ kg}{1000\ kg/m^3}\\\\=0.001\ m^3[/tex]
So, the volume of water is [tex]0.001\ m^3[/tex].
Answer:
Volume of water has a mass of 1 kg is explained below in details.
Explanation:
One liter of h2O has a volume of approximately specifically one kilogram when estimated at its maximum frequency, which happens at about 4 °C. It observes, therefore, that thousand of a liter, recognized as one milliliter (1 mL), of h2O has a volume of about 1 g; 1000 liters of h2O has a volume of about 1000 kg (1 tonne).
True testing means that a serious effort is made to _________.
Question 8 options:
be absolutely positively, without a shadow of a doubt, correct.
create experiments that support your hypothesis
falsify (“disprove”) each possible explanation.
complete testing that supports manufacturers claims, so you can cash in and make money.
Explanation:
This explanation is the opposite of true testing - a term known as falsifiability. Falsifiability, when it relates to science, refers to how it should be possible to prove a hypothesis or theory wrong. Thus, the point of testing for falsifiability is to test in which condition is the theory wrong.
A term that might relate to the phrase ‘true testing’ used in the question would be testability. Which refers to the practice of testing a hypothesis or theory to see whether it is true or false.
True testing has been the scientific method that uses various steps to conclude the findings. "True testing means that a serious effort is made to create experiments that support your hypothesis." Thus, option B is correct.
What is True testing?True testing has been defined as the assessment scientific method that is involved in solving the question and issue by formulating the hypothesis and then researching the possible observations and solution that concludes and proves the findings.
It falsifies or proves the hypotheses right or wrong based on the experimental design setup. It does not falsify each possible explanation, nor is always fully correct. It also is not conducted to support the manufacturing and support it financially.
Therefore, option B. True testing experiments to sustain the hypothesis.

The % yield of Ca(OH)₂ : 62.98%
Further eplanationPercent yield is the compare of the amount of product obtained from a reaction with the amount you calculated
General formula:
Percent yield = (Actual yield / theoretical yield )x 100%
An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients

An atom has an atomic number of 15 and a mass number of 31. How many protons are there in the atom?
Answer:
No of protons = 15
Explanation:
Given that,
Atomic number = 15
Mass number = 31
We need to find the no of protons in the atom.
We know that,
No of protons = Atomic no of the atom
No of protons = 15
Hence, there are 15 protons in the atoms.

Need help. Is this correct
Answer:
Yes, that is correct!
Explanation:
Answer:
Yes
Explanation:
A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.
Is it possible for two different compounds to be made from the exact same two elements? Why or why not? With a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds or do we have a large number of compounds in this world?
PLEASE HELP ASAP
Thank you!!
Answer:
Yes. The two elements can combine to form different compounds.
Explanation:
Two elements can combine at different ratios.
Consider CO and CO₂. Both are made from carbon and oxygen. However, C and O combine at a 1:1 ratio in CO but at a 1:2 ratio in CO₂. CO is a fuel; it burns in the air. CO₂ does not burn in the air; it is used to put out fires and is found in extinguishers. CO and CO₂ are two distinct compounds.
There are many ways for the elements to combine with each other. As a result, the first twenty elements on the periodic table alone can produce a large number of compounds.

What do you think causes a lunar eclipse? (Use your knowledge of solar eclipses and feel free to run the Gizmo to help you.)
Moon reflects the light frim the sun, thats why we are able to see it and it shines in the night. But, we know that Earth revolves around Sun and Moon revolves around Earth. During this revolution, Earth and Moon comes in a position when Earth is in the middle of the Moon and Sun. So, it blocks the light of Sun frim reaching Moon. Hence, we see no reflection and it causes Lunar eclipse.
Answer:
A total lunar eclipse occurs when the moon and the sun are on exact opposite sides of Earth. Although the moon is in Earth's shadow, some sunlight reaches the moon. The sunlight passes through Earth's atmosphere, which causes Earth's atmosphere to filter out most of the blue light.

Thank you
The answer is B
HF, because both fluorine and hydrogen are capable of forming only one covalent bond.
The formula for a compound made from fluorine and hydrogen is HF, because both fluorine and hydrogen are capable of forming only one covalent bond. The correct option is option B.
What is chemical Compound?Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion. Covalent bond is weaker than ionic bond.
There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron.
The formula for a compound made from fluorine and hydrogen is HF, because both fluorine and hydrogen are capable of forming only one covalent bond.

Answer:
I believe it's j, convergent plate boundaries
The type of plate boundary that forms snowy mountains are convergent plate boundaries. option J is correct.
What are convergent plate boundaries?The convergent plate boundaries are which consist of two plates that move toward each other which results in the process called collision of two plates with each other.
The snowy mountains are full of snow which melts due to the change in temperature and leads to the formation of different plates and boundaries and the collision of two continental plates leads to the formation of this.
Therefore, option J is correct, the type of plate boundary that forms snowy mountains are convergent plate boundaries.
