Answer:
line graph
Explanation:
The type of graph would be used to display the data is line graph.
What is graph?Graph is defined as a visual representation, such as a picture or diagram, that shows information or values in a structured way. The graph's goal is to visually represent numerical data so that it can be quickly, simply, and clearly understood. As a result, graphs are visual displays of data.
Although a graphical display is easier to understand, data can also be presented as a table. For this kind of data, a line graph will be used. This will show more clearly how the temperature of the water fluctuates over the course of two hours. Time is an independent variable, whereas temperature is a dependent variable.
Thus, the type of graph would be used to display the data is line graph.

Which answer below correctly identifies the type of change and the explanation for the boiling of water?
physical change because even though the change caused the temperature of the water to increase,
the water's physical properties remained exactly the same
physical change because even though gas formation was observed, the water was undergoing a
state change, which means that its original properties are preserved
chemical change because gas formation was observed, which indicated that the water was
transformed into a different substance
0 chemical change because a temperature change was observed, which indicated that the water was

Explain how NOTHING is ZERO, but ZERO is more than NOTHING?
Answer:
Nothing can be zero, but zero isn't nothing. If someone asks you if you have money and you say "I've got nothing!" when you actually don't have a cent, then you have zero money. However, zero is a number, so it itself is something, therefore more than nothing. So technically, you do have something.
When zero is on a number line, you could classify it as nothing, but it is the number between 1 and -1. Hypothetically speaking, if you took the zero away, wouldn't the number line be the same?
Zero isn't positive or negative. The number zero on a graph, or in a coordinate can tell you where something is. Zero can be a word to describe if something is existent, or non-existent.

The top diagram represents a mixture of S atoms and O2 molecules in a closed container.
Which symbolic notation best represents the molecule in the bottom picture?
A) S2O6
B) SO3
C) 2 SO3
D) 2 S and 6 O
Answer:
S2O6 best represents the bottom picture. When atoms are bonded in a molecule, the number of them is represented as a subscript in a chemical formula.
Explanation:
The symbolic notation that best represents the molecule in the bottom picture is S2O6.
Sulfur is a chemical element that has the symbol S. It also has the atomic number of 16. It should be noted that sulfur is known as the 10th most abundant element that we've in the universe.It should be noted that S2O6 is the chemical formula for Disulfur Hexoxide. Di simply indicates that there are two sulfur atoms. Hexa indicates that there are six oxygen atoms.In conclusion, the symbolic notation best represents the molecule at the bottom is S2O6.

Carbon dioxide in the air dissolves in rain as it falls to Earth. This results in the formation of carbonic acid, a weak acid. Explain why the student blowing into test tube B is similar to the process of forming slightly acidic rain.
Explanation:
Acid rain :
Acid rain is also known as acid deposition. It may be defined as a form of precipitation of the acidic components like nitric acid or sulfuric acid and fall to the earth surface from the atmosphere.
In the context, the student doing the experiment blows air in to the test tube B containing chalk dipped in water is similar to the process of acidic rain as it results in the formation of a weak carbonic acid when the carbon dioxide present in the air mixes with the chalk in the form of calcium carbonate.
Carbon dioxide reacts with water to from carbonic acid which dissociated into hydrogen ion and hydrogen carbonate ion.

60 N net force is applied to a 12 KG box. What is the acceleration of the box?
Answer:
The answer is
5 m/s²Explanation:
The acceleration of an object given it's mass and it's net force can be found by using the formula
[tex]acceleration = \frac{force}{mass} \\ [/tex]
From the question
force = 60 N
mass = 12 kg
So we have
[tex]acceleration = \frac{60}{12} \\ [/tex]

10. When 5.1 x 10^-3 is subtracted from 1.0051 the difference is:
a) 1.0000
b) 1.000
c) 1.00
d) 1.0
To find the difference between 1.0051 and 5.1 x 10⁻³, subtract the second number from the first number from its decimal form.Thus, the correct option is A.
First, convert 5.1 x 10⁻³to decimal form:
5.1 x 10⁻³ = 0.0051 is the decimal form of the given number 5.1 x 10⁻³.
Then subtract the 2 numbers that is,0.0051 from 1.0051:
1.0051 - 0.0051 = 1.0000 which has 4 digits after the decimal.
So, the difference between the two numbers 1.0051 and 5.1 x 10⁻³ is 1.0000.
Thus,the correct option is a) 1.0000 which is the difference between 1.0051 and 5.1 x 10⁻³.

When moving down a Column in the periodic table what stays the same ?
Answer:
Explanation:
When we go down in a column , we are going down in a period . In going down , one additional orbit go on adding to the atom . But the total number of electrons in the outermost orbit which is also called valence electron remains the same .
For example , when we go down in the first group A , the outermost orbit go on changing like 1 s¹ , 2 s¹ , 3 s¹ . 4 s ¹ etc which represents hydrogen , lithium . sodium , potassium etc.
So we see that , it is number of valance electrons that remains constant.

Answer:
A. 8.8 g.
B. 5.3 g.
C. 449 g.
Explanation:
A. Determination of the mass of CO2.
Mole of CO2 = 0.2 mole
Molar mass of CO2 = 12 + (2×16)
= 12 + 32
= 44 g/mol
Mass of CO2 =?
Mole = mass /Molar mass
0.2 = mass of CO2 /44
Cross multiply
Mass of CO2 = 0.2 × 44
Mass of CO2 = 8.8 g
B. Determination of the mass of Na2CO3.
Mole of Na2CO3 = 0.05 mole
Molar mass of Na2CO3 = (2×23) + 12 + (3×16)
= 46 + 12 + 48
= 106 g/mol
Mass of Na2CO3 =?
Mole = mass /Molar mass
0.05 = mass of Na2CO3 /106
Cross multiply
Mass of Na2CO3 = 0.05 × 106
Mass of Na2CO3 = 5.3 g
C. Determination of the mass of Fe(OH)2.
Mole of Fe(OH)2 = 5 moles
Molar mass of Fe(OH)2 = 55.8 + 2(16 + 1)
= 55.8 + 2(17)
= 55.8 + 34
= 89.8 g/mol
Mass of Fe(OH)2 =?
Mole = mass /Molar mass
5 = mass of Fe(OH)2/89.8
Cross multiply
Mass of Fe(OH)2 = 5 × 89.9
Mass of Fe(OH)2 = 449 g.

Calcium carbide ( CaC2) reacts with water to produce acetylene (C2H2) as shown in the unbalanced reaction below: CaC2(s)+H2O(g)->Ca(OH)2(s)+C2H2(g). How many grams of H2O are required to completely react with 82.4g of CaC2
The given reaction can be balanced as follows: CaC2 + 2H2O → Ca (OH)2 + C2H2. Grams of water required to completely react with 82.4 g of CaC2 is 46.28 g.
What is a balanced reaction?
In balanced reaction, the number of each and every element on both side is balanced. In the given reaction to balance the number of H and O, add 2 to H₂O so that, all the species will be equal in number on both side.
Now, as per the balanced reaction, 2 moles of water is required to reacts with 1 mole of CaC2.
Mass of one mole of water = 18 g/mol.
2 mole = 36 g
Mass of one mole of CaC2 = 64.09 g/mol
Thus 36 g of water is required to react with 64.09 grams of calcium carbide. Mass of water required to react with 82.4 g of calcium carbide is calculated as follows:
Mass of water = (36 g×82.4 g)/64.09 g = 46.28 g
Hence, 46.28 grams of water is required to completely react with 82.4 g of calcium carbide.
