Determine el volumen de las siguientes figuras: Un cubo de 3.5 cm. De lado. Una esfera de 5.8 cm. De diámetro. Cubo A= l 3 Esfera A = 4 π R 2
Answer:
42.875cm³ ; 422.73 cm³
Explanation:
Given that:
Volume of a cube (V) = a³
a = 3.5cm
V of a cube = (3.5cm)^3
Volume of a cube = 3.5cm * 3.5cm * 3.5cm
Volume of a cube = 42.875cm³
Volume of a Sphere, V = 4πR²
V = 4 * π * 5.8²
V = 4 * π * 33.64
V = 422.73270
V = 422.73 cm³

There are only 90 naturally occurring elements on Earth but there are millions of different substances explain how this is possible and describe how it applies to at least three examples
Answer:
See explanation
Explanation:
While it is true that there are only about 90 naturally occurring elements, these elements are capable of combining with each other to form millions of substances.
Most of the substances that we see around us today result from a combination of one or more of these naturally occurring elements.
Let us look at three examples;
The carbohydrate in food is composed of carbon, hydrogen and oxygen
The stainless steel materials we use are composed of iron, carbon and other trace elements
Glass is made up of silicon, oxygen and other elements
Only 90 naturally occurring elements capable of combining with each other to form millions of substances.
Compounds:
When two or more elements combine in a certain ratio to form a molecule.
For example-
Water is made up of two hydrogen and one Oxygen ration is 2:1.
If hydrogen and Oxygen combine inn 2:2, they for Hydrogen peroxide.
Water gives life and Hydrogen peroxide can kill a person.
Other examples are,
The carbohydrate in food is composed of carbon, hydrogen and oxygen. The stainless steel is made up of iron, carbon and other trace elements. Glass is composed of silicon, oxygen and other elements.Therefore, only 90 naturally occurring elements capable of combining with each other to form millions of substances.

If you need to produce 9.75 moles of iron(III) oxide (Fe2O3), how many moles of iron will be required? *
Answer: Thus 9.75 moles of iron will be required.
Explanation:
The balanced chemical reaction is:
[tex]2Fe+3O_2\rightarrow 2Fe_2O_3[/tex]
According to stoichiometry :
2 moles of [tex]Fe_2O_3[/tex] are produced by= 2 moles of [tex]Fe[/tex]
Thus 9.75 moles of [tex]Fe_2O_3[/tex] are produced by=[tex]\frac{2}{2}\times 9.75=9.75moles[/tex] of [tex]Fe[/tex]
Thus 9.75 moles of iron will be required.

Answer:
1-1) NaHCO3 + CH3COOH --> NaCH3COO + H2O + CO2
1-2) 0.5 mole of CO2
2-1) 2C4H10 + 13O2 --> 8CO2 + 10H2O
2-2) 4 mol CO2
Explanation:
Question 1
NaHCO3 + CH3COOH --> NaCH3COO + H2O + CO2
To balance the equation, count the number of atoms on both sides of the equation
(1 Na, 1+3+1H, 1+1+1C, 3+2Oxygen) --> (1 Na, 1+1+1C, 3+2H, 2+1+2Oxygen)
Combining the pluses will give you the following
(1 Na, 5H, 3C, 5Oxygen) --> (1 Na, 3C, 5H, 5Oxygen)
Both sides are the same, therefore the chemical equation is balanced (originally).
From the equation, we can see that 1 mole of NaHCO3 produces 1 mole of CO2.
So that means 0.5 mole of NaHCO3 would produce 0.5 mole of CO2.
Question 2
C4H10 + O2 --> CO2 + H2O
Again, count the number of atoms on both sides of the equation
(4C, 10H, 2O) --> (1C, 2H, 3O) This time left does not equal right side
You now need to find factors that can make both sides equal.
C4H10 + O2 --> 4CO2 + H2O Now the C is balanced, let's recount
(4C, 10H, 2Oxygen) --> (4C, 8+1Oxygen, 2H) H&O is still not balanced
C4H10 + O2 --> 4CO2 + 5H2O Now the H is balanced, let's recount
(4C, 10H, 2Oxygen) --> (4C, 8+5Oxygen, 10H) O is still not balanced
C4H10 + (13/2)O2 --> 4CO2 + 5H2O Now the O is balanced
(4C, 10H, 13Oxygen) --> (4C, 13Oxygen, 10H)
But because 13/2 is a fraction, we want to eliminate that by multiplying every reactant and product by 2 (the denominator).
2C4H10 + 13O2 --> 8CO2 + 10H2O Now it's completely balanced!
(8C, 20H, 28Oxygen) --> (8C, 28Oxygen, 20H) Yayy! It's balanced.
Now, 2 mol C4H10 produces 8 mol CO2.
So 1 mol C4H10 produces 4 mol CO2.

Which phrase describes the changes that take place when a gas condenses?
Choose the correct answer
A: loss of energy and increased freedom of particle motion B: gain of energy and increased freedom of particle motion. C: loss of energy and decreased freedom of particle motion
D: gain of energy and decreased freedom of particle motion
Answer:
The Answer is (C)
Explanation:
Reasons are when anything cools or condenses it tends to be more solid, and solids don't move.
Loss of energy and decreased freedom of particle motion describes the changes that take place when a gas condenses. The correct option is option C.
What is phase?The phases of matter, such as liquid, solid, and gas, are its states, yet even in distinct phases, matter can still be in the same condition. Liquid mixes, for instance, can have several phases, including an oil phase as well as an aqueous phase.
On a phase diagram, equilibrium states may also be referred to as phases. Because the characteristics that define the phase include the structure of matter as well as elements like temperature and pressure, when the word "phase" is employed in this context, it is frequently used synonymously with a state of matter. Loss of energy and decreased freedom of particle motion describes the changes that take place when a gas condenses.
Therefore, the correct option is option C.

3.84 L (1 gallon) of water? water's density is 1000 g/1L
Answer:
William Shakespeare (bapt. 26 April 1564 – 23 April 1616)[a] was an English playwright, poet, and actor, widely regarded as the greatest writer in the English language and the world's greatest dramatist.[2][3][4] He is often called England's national poet and the "Bard of Avon" (or simply "the Bard").[5][b] His extant works, including collaborations, consist of some 39 plays,[c] 154 sonnets, two long narrative poems, and a few other verses, some of uncertain authorship. His plays have been translated into every major living language and are performed more often than those of any other playwright.[7] They also continue to be studied and reinterpreted.
Shakespeare was born and raised in Stratford-upon-Avon, Warwickshire. At the age of 18, he married Anne Hathaway, with whom he had three children: Susanna and twins Hamnet and Judith. Sometime between 1585 and 1592, he began a successful career in London as an actor, writer, and part-owner of a playing company called the Lord Chamberlain's Men, later known as the
