Explanation:
1. H2SO4, sulfuric acid, contains three different types of atoms: hydrogen (H), sulfur (S), and oxygen (O). Each of these atoms represents a different . Since the three types are combined in a fixed ratio, this means that H2SO4 is a(n) molecule. 2. The smallest unit of matter that retain all of the physical properties of that type of matter is a(n) atom. 3. is anything that occupies space and/or has any substance. 4. If two or more atoms are bonded together, they form a(n) . 5. The scientific study of matter is called . 6. Within a plant, water (H2O) and carbon dioxide (CO2) can be combined (using the energy of sunlight) to produce glucose (C6H12O6) and oxygen (O2). If you were to write out this chemical reaction, water and carbon dioxide are each an example of a(n) while glucose and
Answer:
The blanks can be completed with words in the following sequence

2) atom
3) matter
4) compound
5) chemistry
6) reactants
product
Explanation:
In H2SO4, atoms of hydrogen, sulphur and oxygen represent different elements that are combined to form the compound.
The smallest indivisible unit of matter that still retains all the properties of matter is an atom. Matter is anything that has weight and occupy space.
Atoms combine in fixed ratios to form compounds. Chemistry studies matter scientifically and pays specific attention to the changes that matter undergoes.
Considering the reaction of photosynthesis, water and carbon dioxide combine to give glucose so the water and carbon dioxide are reactants while the glucose is the product of the reaction.

which is not a redox reaction?
a. Formation of ammonium sulphate from ammonia and sulphuric acid
b. formation of nitrogen monoxide from ammonia
c. formation of sulphuric acid from sulphur
d. formation of zinc from zinc sulphide
help me please
Answer:
D. formation of zinc from zinc sulphide
Explanation:
A redox reaction could be explained as an artificial reaction in which electrons are moved between two reactants partaking in it. This substitution of electrons can be recognized by examining the variations in the oxidation states of the reacting classes. The generation of hydrogen fluoride is an illustration of a redox reaction. We can crack the reaction down to investigate the oxidation and loss of reactants.

7. The atomic number equals the number of blank or blank in a stable atom of an element.
Answer:
Atomic Number
Neutral atoms of an element contain an equal number of protons and electrons. The number of protons determines an element's atomic number (Z) and distinguishes one element from another.
Explanation:
if a star were 36 trillion miles from the earth it would be about ___ light years from the earth
Answer:
6.12light years
Explanation:
Given parameters:
Distance of star from earth = 36 trillion miles
Unknown:
Distance in light years = ?
Solution:
A light year is the distance light travels in one year.
1 mile = 1.7 x 10⁻¹³ light years
36 trillion miles = 36 x 10¹² x 1.7 x 10⁻¹³ light years
= 6.12light years
The molar mass of a gas is 56 grams. What is its density at STP in grams per liter?
Answer:
d = 2.5 g/L
Explanation:
Given data:
Molar mass of gas = 56 g/mol
Density of gas = ?
Temperature = 273.15 K
Pressure = 1 atm
Solution:
Formula:
d = PM/RT
d = 1 atm × 56 g/mol / 0.0821 atm.L/mol.K ×273.15 K
d = 56 atm g/mol./ 22.42 atm.L/mol
d = 2.5 g/L
Meg used two examples to represent two different states of matter.
Example 1: Young children dancing slowly around one another
Example 2: Newborn babies sitting in their given spots in a crib
Which statement is correct? (1 point)
a
Example 1 represents a gas and Example 2 represents a liquid.
b
Example 1 represents a liquid and Example 2 represents a gas.
c
Example 1 represents a liquid and Example 2 represents a solid.
d
Example 1 represents a solid and Example 2 represents a liquid.
Answer:
c Example 1 represents a liquid and Example 2 represents a solid.
Explanation:
Example 1: Young children dancing slowly around one another
The young children dancing slowly around one another can be pictured as the flow of liquid. In liquids, the molecules are held about weakly and they slide on top of each other. They are held by weak attractive forces. This is clear picture of a liquid.
Example 2: Newborn babies sitting in their given spots in a crib
This is clear example of a solid. In a solid the molecules are held about a fixed spot. The attractive forces in liquids is very great and the molecules therein do not move about randomly.
The volume of an object is 55mL in this city is 30g/mL. what is its mass
Answer:
Mass = 1650g
Explanation:
30g per mL is the density I suppose...
Solve for m!
30g/mL = m/55mL
Multiply by denominator to get numerator!
30* 55 =1650g
m = 1650g

What is the volume of a 25 g object with a density of 9.1 g/mL? please help me
Answer:
The answer is 2.75 mLExplanation:
The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{density} \\ [/tex]
From the question we have
[tex]volume = \frac{25}{9.1} \\ = 2.747252...[/tex]
We have the final answer as
2.75 mLHope this helps you
Under a certain set of conditions, the percent yield of a reaction that produces carbon dioxide is 75.0%. What mass in grams of CO2 will actually be recovered if the theoretical yield is 26.7 grams?
Answer:
Actual yield = 20.03g
Explanation:
[tex]% yield = 100.\frac{actual yield}{theoretical yield}[/tex]% [tex]yield[/tex] = [tex]100. \frac{actual \ yield}{theoretical \ yield}[/tex]
Actual yield = % yield.(theoretical yield) / 100
Actual yield = 75.26.7/100
Actual yield = 20.025
Answer: I got 20.025 and then I rounded it to 20.0

Explanation:
Use your answers from questions 1–3 as the basis for the first section of your lab report. This section provides your reader with background information about why you conducted this experiment and how it was completed. Outline the steps of the procedure in full sentences. It also provides potential answers (your hypothesis/es) relative to what you expected the experiment to demonstrate. This section should be 1–3 paragraphs in length.
Answer:
1-state what the lab is about, that is, what scientific concept (theory, principle, procedure, etc.) you are supposed to be learning about by doing the lab. You should do this briefly, in a sentence or two. If you are having trouble writing the opening sentence of the report, you can try something like: "This laboratory experiment focuses on X…"; "This lab is designed to help students learn about, observe, or investigate, X…." Or begin with a definition of the scientific concept: "X is a theory that…." 2-give the necessary background for the scientific concept by telling what you know about it (the main references you can use are the lab manual, the textbook, lecture notes, and other sources recommended by the lab manual or lab instructor; in more advanced labs you may also be expected to cite the findings of previous scientific studies related to the lab). In relatively simple labs you can do this in a paragraph following the initial statement of the learning context. But in more complex labs, the background may require more paragraphs.

False
which bond is the strongest
Answer:
C
Explanation:
When two atoms share electrons, a covalent bond is formed. The more electrons shared between atoms, the stronger the bond. Single bonds have two electrons shared, double bonds have four electrons shared, and triple bonds have six electrons shared.
Therefore, triple bonds are the strongest as they require more energy to break.
Hope that helps.
