#I'm not sure#happy learningIn Experiment 1, what volume did the propane gas occupy in the Erlenmeyer flask before the addition of any water?
This question is mentioning an experiment that is not being described about the volume of the propane gas in an Erlenmeyer before the addition of water.
In this case, since no information is given, it is possible to propose a suggested procedure of how to figure it out via gas laws, specifically, the ideal gas one, since no change is decribed before the addition of water:
[tex]PV=nRT[/tex]
Thus, you can solve for the volume, by dividing both sides by the pressure, so that you will get:
[tex]V=\frac{nRT}{P}[/tex]
Now, to ensure a correct calculation, make sure you have the moles (divide by the molar mass of propane, 44,1 g/mol, if you were given the grams), the temperature in K (add 273.15 if you have degree Celsius), the ideas gas constant as 0.08206 and the pressure in atm, in order to have consistent units.
If you need the volume in milliliters, you will need to multiply the previous answer by 1000 in order to perform the appropriate conversion.

The first stage of the experiment is focusing only on the physical properties of acidic property.
What is physical property?A physical property would be any quantifiable attribute whose value describes the condition of a physical system. Changes in a system's physical attributes are able to characterize its transitions between brief states. Physical attributes are sometimes known as observables.
Physical characteristics are frequently classified as intense or extensive. An intense property is independent of the system's size or extent, as well as the amount of material in the item, whereas an extended property has an additive link. The first stage of the experiment is focusing only on the physical properties of acidic property.

1. Describe what happens when two substances at different temperatures come into contact. Describe how the
law of conservation of energy applies to this system.
Answer:
Explanation:
When two substances at different temperatures like into contact, the substance that is at higher temperature will transfer energy, in the form of heat, to the substance that is at lower temperature, until their temperatures get equal.
In this case, if the two substances are isolated of the rest of the universe, the law of conservation of energy states that the heat released by the substance initially at higher temperature is the same amount of heat gained by the substance originally at lower temperature.

What element is being reduced in the following redox reaction? Cr(OH)4-(aq) ClO-(aq) → CrO42-(aq) Cl-(aq).
The element that is being reduced in the given redox reaction is Cl (Chlorine)
The given redox reaction is
Cr(OH)₄⁻(aq) + ClO⁻(aq) → CrO₄²⁻(aq) + Cl⁻(aq)
First, we will define the terms oxidation and reduction
Oxidation can be defined as an increase in oxidation number
Reduction is defined as a decrease in oxidation number
This means the element that is being reduced in the reaction would have a decrease in oxidation number.
Oxidation number of Cr in Cr(OH)₄⁻ is +3; and the oxidation number of Cr in CrO₄²⁻ is +6. This is an increase in oxidation number and it means Cr is being oxidized.
Oxidation number of Cl in ClO⁻ is +1; and the oxidation number of Cl in Cl⁻ is -1. This is a decrease in oxidation number and it means Cl is being reduced.
Hence, the element that is being reduced in the given redox reaction is Cl (Chlorine).

Why do we fill balloons
with helium gas instead
of oxygen gas?
Answer:
Helium is less dense. Because helium is lighter than air, a helium balloon rises, just as an air bubble rises in more dense water
Explanation:
Also why not. It just is.
Answer:
This is due to the fact that helium has a lower density. A helium balloon rises like an air bubble in more dense water because helium is lighter than air. Another gas lighter than air is hydrogen, which is even lighter than helium.

Which action reflects irresponsible lab safety behavior?
A chemist has dissolved a certain substance in water. The chemist knows that more of the substance could be dissolved into the water before it stops dissolving. Therefore, the current solution is
.
Answer is: the current solution is unsaturated.
Unsaturated solution means that more of a substance can be dissolve.
For example:
Solubility of potassium chlorate (KClO₃) at 100 grams of water at 80°C is 37.5 g, that means that all 37.5 g is completely dissolves, this is the saturated solution.
If we add 20 grams of potassium chlorate in 100 grams of water, there is less solute than the saturated solution, so this is unsaturated solution.

Answer:
Copper
Explanation:
Copper has this electronic configuration.
You can count the total number of electrons
= 29
Cu is the 29 th in the periodic table.( atomic number = 29)
Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Therefore, the given electronic configuration represents copper element.
What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.
The systematic distribution of electrons in the various atomic orbitals is called its electronic configuration. The atomic number of copper is 29. The electronic configuration of copper is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹ 3d¹⁰. 1,2,3 represents the number of shells and s and represents the orbitals.
