Compare an object sliding across carpet and that same object sliding across a bare floor. Why is the object quicker to slow down on carpet than on the bare floor?
The same object moves quicker through the bare floor than carpet as there has been no friction force acting on the object on the bare floor.
The friction force has been the force that has been applied against the motion of the object. The friction force has been created with the uneven surfaces that result in the slowing of the motion of the object.
The object has been slid against the carpet and the bare floor. The carpet has been the rough surface, that has been able to apply the friction force against the object.
The bare floor has been the smooth surface that has been able to slide down the object without the application of any friction force that has been able to move the object faster.
Thus, the same object moves quicker through the bare floor than carpet as there has been no friction force acting on the object on the bare floor.

The compound V₂O₅ has a Seebeck coefficient at a temperature of 50 °C of -990 μV/K.
What is a compound?Compound is defined as a chemical substance made up of identical molecules containing atoms from more than one type of chemical element.
Molecule consisting atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding present in them.They are:
1)Molecular compounds where in atoms are joined by covalent bonds.
2) ionic compounds where atoms are joined by ionic bond.
3)Inter-metallic compounds where atoms are held by metallic bonds
4) co-ordination complexes where atoms are held by co-ordinate bonds.
They have a unique chemical structure held together by chemical bonds .Compounds have different properties as those of elements because when a compound is formed the properties of the substance are totally altered.

2) Gas in a balloon occupies 3.3 L. What volume will it occupy if the pressure
is changed from 100 kPa to 90 kPa,
Answer:
The answer is 3.7 LExplanation:
The new volume can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we are finding the new volume
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
From the question we have
[tex]V_2 = \frac{3.3 \times 100000}{90000} = \frac{330000}{9000 } \\ = 3.666666...[/tex]
We have the final answer as

Explanation:
The Synthesis Reaction of aluminum (Al) and iodine (I) forms a new, more complex
product. What is the product?
Answer:
Aluminum iodide (AlI₃)
Explanation:
The synthesis reaction of aluminum (Al) and iodine (I) can be illustrated as shown below:
Aluminium exhibit trivalent positive ion (Al³⁺)
Iodine exhibit univalent negative ion (I¯)
During reaction, there will be an exchange of ion as shown below:
Al³⁺ + I¯ —> AlI₃
Thus, we can write the balanced equation for the reaction as follow:
Al + I₂ —› AlI₃
There are 2 atoms of I on the left side and 3 atoms on the right side. It can be balance by putting 2 in front of AlI₃ and 3 in front of I₂ as shown below:
Al + 3I₂ —› 2AlI₃
There are 2 atoms of Al on the right side and 1 atom on the left side. It can be balance by putting 2 in front of Al as shown below:
2Al + 3I₂ —› 2AlI₃
Thus the equation is balanced.
The product on the reaction is aluminum iodide (AlI₃)

In this periodic table, which type of element is shown in green boxes?
A. Noble gases
B. Metalloids
C. Nonmetals
D. Metals
The correct answer is B. Metalloids
Explanation:
In this periodic table, the green boxes include elements such as Boron (B), Arsenic (As), and Antimony (Sb). All these elements are known in chemistry as semimetals or metalloids. This classification is because these elements cannot be completely classified into metals or non-metals. Moreover, they all display similar properties including some level of conductivity, malleability, and solid-state. According to this, the correct answer is B.

how is sonoluminescence similar to what we see in fireworks?
Answer:
Explanation:
Sonoluminescence is a phenomenon in which small gas bubbles burst to produce light when intense sound wave is introduced. Thus, it can be said that sound energy is converted to light energy here. This is similar to the process of how fire crackers work except that sonoluminescence occurs in a liquid medium while firecrackers work in solid media. In firecrackers, when the tip is lit with fire, the initial explosion is caused by the expansion of some nitrogen and carbon present in some constituent compounds, this explosion produces heat which causes some other constituent chemicals in the firecracker to quickly react and produce light. Thus, this can also be said to convert sound energy to light energy and are thus similar to what occurs in sonoluminescence.
