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

A motorcycle starts at rest and moves a distance of 460m .
If it has constant acceleration of 4m55 m/s2 what is its final velocity
Answer:
The final velocity of the motorcycle is 64.7 m/s
Note: Since the value for the acceleration of the motorcycle is not clear, it is assumed to be 4.55 m/s² in the calculation
Explanation:
Using the equation of motion that contains all the given values in the question: v² = u² + 2as
where v is final velocity; u is initial velocity; a is acceleration; s is horizontal distance
v = ?, u = 0 (since the motorcycle starts from rest), a = 4.55 m/s², s = 460 m
v² = 0² + 2 * 4.55 * 460
v² = 4186
take square root of both sides
v = 64.7 m/s
Therefore, the final velocity of the motorcycle is 64.7 m/s

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. Which of the following represents the tiny parts within a cell? *
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.

A sample of calcium oxide (CaO) has a mass of 2.80 g. The molar mass of CaO is 56.08 g/mol. How many moles of CaO does this sample contain?
0.0499
20.0
58.9
157
Answer:
A) 0.0499
Explanation:
According to the mole concept, 2.80 g of calcium oxide sample has 0.0499 moles.
What is mole concept?
According to the mole concept,mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.
It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.
It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons. Molar mass has units of gram per mole . In case of molecules, where molar mass in grams present in one mole of atoms is its atomic mass.
As per the formula for number of moles, which is mass/molar mass
number of moles of calcium oxide is:2.80/56.08=0.0499 moles.
Hence, 2.80 g sample of calcium oxide has 0.0499 moles.

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)
