C. Red, violet, green
B. Green, blue, red
D. Red, green, violet
Answers
Answer:
The correct answer is - D. Red, green, violet.
Explanation:
Visible light is the spectrum of light that can be seen by the naked eyes of humans without any equipment. This spectrum has various frequency light that helps us see things in color. The frequency of light ranges between seven different colors in which violet has the highest frequency and red has the lowest.
The different frequencies are as follows:
color frequency
red (limit) 1.77
red 1.91
orange 2.06
yellow 2.14
green 2.25
cyan 2.48
blue 2.75
violet (limit) 3.10
On this basis of this the group of colors of the visible light is listed from
lowest to the highest frequency - Red, green, violet

Answers
Answer:
3.0 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\ [/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
[tex]n = \frac{1.8 \times {10}^{24} }{6.02 \times {10}^{23} } = 2.990.. \\ [/tex]

When the space shuttle took off it used two different rocket systems. The main engines were powered by combining oxygen and hydrogen in the highly exothermic reaction
2H2 + O2 ⇌ 2H2O
The fuel was stored in that brown tank in liquid form as liquid oxygen (LOX) and liquid hydrogen (LH2). Liquids are much more dense than gases, so storage in the liquid phase allows the shuttle to carry an immense amount of fuel.
Unfortunately, that fuel made up the majority of the weight of the shuttle at liftoff. So most of what the shuttle engines lifted from the ground was fuel. That means it was very important not to have too much of one or the other reactant on board. We'd want just enough hydrogen to react with the amount of oxygen on board, and vice versa. That's where stoichiometry and moles are essential. Sana makatulong po sa inyo
1. What volume of gas (NU) is formed by the interaction of 13 g of zinc with 400 g of sulfuric acid solution with a mass fraction of 10%?
Answers
Answer:
4.5L of gas are produced
Explanation:
Based on the reaction:
Zn + H2SO4 → ZnSO4 + H2(g)
Where 1 mole of Zn reacts with 1 mole of sulfuric acid to produce 1 mole of H2, the gas
To solve this question we must find the moles of each reactant in order to find limiting reactant and, thus, the moles of H2 produced. Then using PV=nRT we can find the volume of the gas:
Moles Zn -Molar mass: 65.38g/mol-
13g * (1mol / 65.38g) = 0.20 moles Zn
Moles H2SO4 -Molar mass: 98g/mol-
400g * 10% = 40g H2SO4 * (1mol / 98g) = 0.41 moles H2SO4
As the ratio of the reaction is 1:1, the limiting reactant is Zn and the moles produced of H2 are 0.20 moles
Using PV = nRT; V = nRT/ P
Where V is the volume of the gas
n are the moles = 0.20 moles
R is gas constant = 0.082atmL/molK
T is absolute temperature = 273.15K at STP
P is pressure = 1atm at STP
V = 0.20mol*0.082atmL/molK*273.15K / 1atm
V = 4.5L of gas are produced

What is the balanced chemical equation?A chemical equation represents a chemical reaction in terms of the chemical symbols of the substances. A chemical equation of a reaction posses of participated reactants, formed products, and an arrow to indicate the direction of the chemical reaction.
The chemical equation of a reaction in which the number of atoms of each element is equal on either side of the equation is known as a balanced chemical equation.
The law of conservation of mass is always followed by a balancing of a chemical equation. By following this law, the total mass of all the elements on the reactant side will be equal to the total mass of all elements on the product side in a balanced chemical equation.
Therefore, the number of hydrogen atoms on the reactant side is equal to 6 (4+2) and the same number of atoms will be on the product side.

Answers
Answer:
Explanation:
Heat is a reactant.
If the equation requires heat to occur, the reaction is endothermic
The equation would have this model
A + B + heat =====> C + D
If the equation gives away heat, then it is exothermic
The equation would look like this. (I'll use a common reaction)
CH4 + 2O2 - heat ===> CO2 + 2H2O
The heat is minus when it has to be given away.
The nature particle model of matter describe the property of solid, liquid and gas in molecular level. Which of the given statements below is TRUE?
A. Matter is made up of large particles.
B. Particles of matter have spaces between them.
C. Particles of matter are not moving all the time.
D. The particles of matter do not attract each other.
Answers
Answer:
B. Particles of matter have spaces between them.
Explanation:
The particle nature model of matter is an model used to explain the properties and nature of matter. The statements of the particle nature model of matter are as follows :
1. Matter is made of small particles of atoms or molecules.
2. The particles of matter have space between them. The spaces between the particles are least in solids as they are closely packed together but are greatest in gases whose particles are far apart from each other.
3. The particles of matter are in constant motion at all times. Solids particles are not free to move due to strong molecular forces between the particles, but are constantly vibrating in their mean positions. Liquid particles free to move due to lesser molecular forces while gas molecules which have negligible intermolecular forces have the greatest ability to move.
4. The particles of matter are attracted to each other by intermolecular forces. These forces are greatest in solids and least in gases.
The correct option is B.

Group of answer choices
Equation 2, because K being more reactive, exchanges position with Pb in PbNO3
Equation 2, because K being more reactive, exchanges position with N in PbNO3
Equation 1, because Mg being more reactive, replaces N from PbNO3
Equation 1, because Mg being more reactive, replaces Pb from PbNO3
Answers
Answer:
Equation 2, because K being more reactive, exchanges position with Pb in PbNO3.
Explanation:
Hello there!
In this case, according to the given reactions, it is possible to realize that according to the reactivity series, since K is is group 1A of alkali metals, we infer it is by far more reactive than magnesium, for that reason last two choices can be easily discarded. Now, considering equation 2, it would be necessary to complete it to figure out the correct option:
[tex]Pb(NO_3)_2 + KI \rightarrow PbI_2+KNO_3[/tex]
Whereas it can be seen that potassium exchanges position with Pb according to the double displacement reaction; therefore, the correct answer is "Equation 2, because K being more reactive, exchanges position with Pb in PbNO3".
