Combustion, or __________, is an example of one of the most familiar chemical changes. Melting of ice, likewise, is one of the most common examples of physical changes. When a piece of coal burns, combines with the carbon in the coal. The products are carbon dioxide gas, water vapor, and a lot of ash. After careful measurements are taken, the of the reactants (coal and oxygen) is to the mass of the products (carbon dioxide, water vapor, and ash). During the_________ reaction, the quantity of matter is unchanged. Similarly, when 10 grams of ice__________ , grams of water is obtained. Mass is_________ in this change as well.
Answers
Answer:
a) Burning
b) physical
c) 10
d) constant
Explanation:
Mass remains same in a physical reaction. It changes only in chemical reactions where some of the mass is lost as energy /heat.
Thus, during combustion mass changes while during melting mass of water do not changes.

Muriatic acid is often used to remove rust. A solution of muriatic acid, HCl, reacts with Fe203 deposits on
industrial equipment. How many liters of 5.00 M HCl would be needed to react completely with 339 g
Fe203?
Answers
Answer:
2.54 L
Explanation:
Step 1: Write the balanced neutralization equation
6 HCl + Fe₂O₃ → 3 H₂O + 2 FeCl₃
Step 2: Calculate the moles corresponding to 339 g of Fe₂O₃
The molar mass of Fe₂O₃ is 159.69 g/mol.
339 g × 1 mol/159.69 g = 2.12 mol
Step 3: Calculate the moles of HCl that react with 2.12 moles of Fe₂O₃
The molar ratio of HCl to Fe₂O₃ is 6:1. The reacting moles of HCl are 6/1 × 2.12 mol = 12.7 mol
Step 4: Calculate the volume of HCl
12.7 moles are in 5.00 M (5.00 mol/L) HCl. The required volume is:
12.7 mol × 1 L/5.00 mol = 2.54 L

i If a chemical system is at equilibrium, any change in the system will always result in an increase of which of the following?
1.The reaction that opposes the change
2. The concentration of the product
3. The concentration of the reactants
4. The temperature of the system
Answers
Answer:
1.The reaction that opposes the change
Explanation:
Consider the reaction;
A + B ⇄ C + D
If a constraint such as a change in temperature, pressure or volume is imposed on this chemical system in dynamic equilibrium, the equilibrium position will shift so as to annul the constraint.
This shift in the equilibrium position will favour either the forward or reverse reaction depending on the type of constraint imposed on the system.
Hence, If a chemical system is at equilibrium, any change in the system will always result in an increase of the reaction that opposes the change.

What is the difference between 13.254 m/s and 7.7 m/s? Round your answer to the correct number of significant digits.
Answers
Answer:
5.6 m/s
Explanation:
Given,
First number = 13.254 m/s
Second number = 7.7 m/s
We need to find the difference between these two numbers. First we round off 13.254 to one decimal place i.e. 13.254 = 13.3 m/s
The difference between them is given by :
D = 13.3 - 7.7
= 5.6 m/s
Hence, the difference of the two numbers is 5.6 m/s.

Thermosetting polymers are less likely to be recycled than thermoplastic polymers because: Thermosetting polymers are less likely to be recycled than thermoplastic polymers because: Some other reason. They are so cheap that it is not worthwhile to recycle them. They cannot be re-melted by heating to form into new shapes. They are so durable that there are not enough thermosetting polymers in the waste stream to set up a recycling program.
Answers
Answer:
They cannot be re-melted by heating to form into new shapes.
Explanation:
Recycling refers to the process of melting a plastic and making it into another shape or size.
Thermoplastics can be softened repeatedly, melted and remoulded. Thermosetting polymers can not be softened, melted and remoulded once they are formed.
Hence, thermosetting polymers cannot be re-melted by heating to form into new shapes therefore they can't be recycled.
what blood vessels and chambers of the heart does a red blood cell pass as it delivers oxygen from the lungs to the brain and return to be oxygenated again.
Answers
Answer:
capillaries
Explanation:
hope it helps if I'm not tell me right away.
Answer:
Carotid artery, Jugular veins
The chambers are explained below.
Explanation:
THE BLOOD VESSELS
The carotid artery carries red blood (oxygenated) to the head and the neck region and that obviously include the brain via the aorta. To be precise the internal carotid artery supplies oxygenated red blood cells to brain. The jugular veins carry deoxygenated red blood cells from the head back to the heart via the superior vena cava. The most important function of the jugular vein is to drain deoxygenated blood from brain.
THE CHAMBERS
The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle which also pumps the same oxygenated blood to the rest of the body through the aortic valve (aorta).
The right atrium receives deoxygenated blood from the body via the vena cava and pumps the deoxygenated blood to the right ventricle which pumps the deoxygenated blood to be oxygenated by the lungs via the pulmonary valve (pulmonary artery).
CONCLUSION
The oxygenated red blood cells from the lung pass through the pulmonary vein through the left atrium to the left ventricle through the carotid artery (internal carotid artery) via the aorta to the brain and
The deoxygenated red blood cells in the brain are drained through the jugular vein via the superior vena cava to the right atrium, which pumps the deoxygenated blood to the right ventricle. From here the deoxygenated blood is pumped to the lungs via the pulmonary artery for oxygenation.
This is my answer, thus if I got your question right.

1.35 m solution NaOCl in water is prepared. What is the mole fraction of the NaOCl?
Answers
Answer:
NaOCl + H2O → HOCl + NaOH
so the mole fraction is = moles of NaOCl/(moles of NaOCl+moles of H2O)
so for 1.35 NaOCl it will require 1.35 moleof H2O
mole fraction = 1.35/(1.35+1.35)
mole fraction = 1/2 =0.5
is it correct i d ek but i tried :)
The mole fraction of the NaOCl is 0.0237
We'll begin by calculating the mole of solute (NaOCl) in the solution.
Molality = 1.35 mMass of water = 1 KgMole of NaOCl =?Mole = Molality x mass (Kg) of water
Mole of NaOCl = 1.35 × 1
Mole of NaOCl = 1.35 mole
Next, we shall determine the mole of water.
Mass of water = 1 Kg = 1000 gMolar mass of water = 18.01 g/mol Mole of water =?Mole = mass / molar mass
Mole of water = 1000 / 18.01
Mole of water = 55.52 moles
Finally, we shall determine the mole fraction of NaOCl.
Mole of NaOCl = 1.35 moleMole of water = 55.52 moles Total mole = 1.35 + 55.52 = 56.87 moles Mole fraction of NaOCl =?Mole fraction = mole / total mole
Mole fraction of NaOCl = 1.35 / 56.87
Mole fraction of NaOCl = 0.0237
