5. The diagram above shows what happened when an irregular solid was immersed in water. This irregular solid has the same mass as a gold block, which is 2 cm wide by 2 cm high by 5 cm long. Using the method described in the passage, compare the density of the unknown with the density of gold.
A. Equal to gold
B. Less than gold
C. Greater than gold
D. Cannot be determined
Answers
The density of the unknown will be greater than the density of gold.
An overview will be given since the diagram isn't given. The formula to calculate the density of an irregular shape will be the mass divided by the volume.
The density is the mass per volume. From the information given, since they've the same mass, then it means that the volume of the gold will be more than the volume of the unknown. Therefore, the density of the unknown will be greater than gold.

An object has a mass of 4 grams and a volume of 2 cm3. What is the density of the object
Answers
Answer:
The answer is 2.0 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
From the question
mass = 4 g
volume = 2 cm³
We have
[tex]density = \frac{4}{2} \\ [/tex]
We have the final answer as
2.0 g/cm³Hope this helps you
Answer:
D = 2 g/cm³
Explanation:
Density = mass over volume
D= m/v
Step 1: Define
m= 4 grams
v= 2 cm³
Step 2: Substitute and Evaluate
D= 4 g/2 cm³
D= 2 g/cm³

The total thermal energy of a system is not only dependent on the state of the material but also on the (resistance, heat, temp, half-life) and the total number of (atoms, currents, compounds, electromagnetic waves) in the system.
Answers
Answer:
The correct options are;
1) Heat
2) Atoms
Explanation:
The heat required to raise a unit mass of a substance by one degree which is the specific heat capacity of the substance, is a quantity characteristic of a given substance and the amount of temperature change experienced by the substance when an amount of heat energy transferred to the substance is a function of the mass of the substance, which is a function of the number of atoms present in the substance.
So also, the total thermal energy that is stored by a substance, that causes a given amount of temperature change, is a function of the heat capacity of the substance.

after eating an apple and levaing it on top of the table. what will happend to the color of the inner part of the apple? what makes the color of the apple change
Answers
Answer:
Answer Below
Explanation:
When you leave an apple on a table outside it will turn brown. This happens because when you cut an apple, you are exposing it's insides to the oxygen in the air. This causes the PPO (polyphenol oxidase) enzyme in the apple's flesh to oxidize the polyphenols, turning them into some other brown colored products. Hence, the color change.
Answer:
brown i can't explain because its a matter of the atoms in the apple mixing with the air and apple is made with nitrogen
Write a complete, balanced chemical equation where tin metal reacts with aqueous hydrochloric acid to produce tin(II) chloride and hydrogen gas. Include states.
From the equation, which element is oxidized, and which element is reduced?
Answers
Answer:
1. The balanced equation is given below:
Sn (s) + 2HCl (aq) –> SnCl₂ (aq) + H₂ (g)
2a. H is oxidized.
2b. Sn is reduced.
Explanation:
1. Balanced equation for the reaction between tin (Sn) metal and aqueous hydrochloric acid (HCl) to produce tin(II) chloride (SnCl₂) and hydrogen gas (H₂).
This is illustrated below:
Sn (s) + HCl (aq) –> SnCl₂ (aq) + H₂ (g)
There are 2 atoms of Cl on the right side and 1 atom on the left side. It can be balance by putting 2 in front of HCl as shown below:
Sn (s) + 2HCl (aq) –> SnCl₂ (aq) + H₂ (g)
Now, the equation is balanced
2. Determination of the element that is oxidize and reduced.
This can be obtained as follow:
We shall determine the change in oxidation number of each element.
NOTE:
a. The oxidation number of H is always +1 except in hydrides where it is –1.
b. The oxidation state of Cl is always –1.
Sn (s) + 2HCl (aq) –> SnCl₂ (aq) + H₂ (g)
For Tin (Sn):
Sn = 0
SnCl₂ = 0
Sn + 2Cl = 0
Cl = – 1
Sn + 2(–1) = 0
Sn – 2 = 0
Collect like terms
Sn = 0 + 2
Sn = +2
Therefore, the oxidation number of Tin (Sn) changes from 0 to +2
For H:
H = +1
H₂ = 0
The oxidation number of H changes from +1 to 0
For Cl:
Cl is always –1. Therefore no change.
Summary:
Element >>Change in oxidation number
Sn >>>>>>>From 0 to +2
H >>>>>>>>From +1 to 0
Cl >>>>>>>No change
Therefore,
Sn is reduced since its oxidation number increased from 0 to +2.
H is oxidized since it oxidation number reduced from +1 to 0
The balanced chemical equation for the reaction is
Sn(s) + 2HCl(aq) → SnCl₂(aq) + H₂(g)
and the element that oxidized is tin (Sn) while the element that is reduced is hydrogen (H)
The balanced chemical equation for the reaction where tin metal reacts with aqueous hydrochloric acid to produce tin(II) chloride and hydrogen gas is
Sn(s) + 2HCl(aq) → SnCl₂(aq) + H₂(g)
From the equation,
The element that is oxidized is tin (Sn), because the oxidation state of Sn increased from 0 to +2
The element that is reduced is hydrogen (H), because the oxidation state of H decreased from +1 to 0.
Hence,
The balanced chemical equation for the reaction is
Sn(s) + 2HCl(aq) → SnCl₂(aq) + H₂(g)
and the element that oxidized is tin (Sn) while the element that is reduced is hydrogen (H).

3. In an exercise to teach students how to use and analytical balance, the instructor
gives a student a quarter which has been pre-weighed as 5.6026 g. The weight that the
student obtains for the same quarter is 5.6013 g. What is the percent error in the
students reading?
Answers
Answer:
The percent error is 0.023%.
Explanation:
Pre-weighed of a quarter is 5.6026 g.
The weight that the student obtains for the same quarter is 5.6013 g.
We need to find the percent error in the students reading. It is given by the formula as follows :
[tex]\%=\dfrac{|\text{original value-calculated value}|}{\text{original value}}\times 100[/tex]
Putting all the values, we get :
[tex]\%=\dfrac{5.6026 -5.6013 }{5.6026 }\times 100\\\\\%=0.023\%[/tex]
So, the percent error is 0.023%.
