What colors are the fireworks in the photo? How do you
think the matter and energy of fireworks of different colors are similar and
different?

Answers

Answer 1

Answer:

Shortly after, the electron will fall back down to a lower energy level, releasing energy in the form of light. Therein lies the key to colorful fireworks!

Answer 2

The matter and energy of fireworks simply rely on the flow of electrons from the ground stage to the excitatory stage.

What is Matter?

Matter may be defined as any sort of substance that is constructed of numerous types of particles that occupy physical space and possess inertia. In simple words, matter may be characterized as anything which occupies space and has mass.

When the electrons move from the ground stage to the excitatory stage, they require a significant amount of energy in any form. But when they fall back to the ground stage from the excitatory stage, they liberates energy.

The same principle is applied in the colorful observation of fireworks. The stored energy is released and different colors of fireworks become visible.

Therefore, the matter and energy of fireworks simply rely on the flow of electrons from the ground stage to the excitatory stage and vice-versa.

Because too much Carbon Dioxide can kill us.

Explanation:

^^ what he said. carbon dioxide, if there is enough in our body, can eventually kill us. it can be seen with deep sea divers, which after several continuous deep dives can have a excessive amount of carbon dioxide in there body to a lethal amount, having to force them into special rooms which allows the deep sea divers to decompress slowly and remove a good bit of the dioxide to lower the amount in them.

Which of the following models best demonstrates the law of conservation of mass??
(LOOK AT THE PICTURES)!!

Answers

Answer:

i think its D

Explanation:

The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

Taking into account the law of conservation of mass,

The Law of Conservation of Matter is also called the law of conservation of mass or the Law of Lomonósov-Lavoisier. This law postulates that "The mass is not created or destroyed, only transformed."

This means that the reagents interact with each other and form new products with different physical and chemical properties than those of the reagents. And this is because the atoms of the substances are ordered differently.

But the quantities of the masses involved in a given reaction must be constant throughout it, that is, they will not have changed in their proportions when the reaction ends. Then the mass before the chemical reaction is equal to the mass after the reaction.

The exception to the rule is nuclear reactions, in which it is possible to convert mass into energy and vice versa.

Finally, the correct answer is option A. because the atoms of the substances are ordered differently, this is the reagents interact with each other and form new products.

Selena is learning about how engineers choose metals for spacecraft. She discovers that spacecraft engineers often mix other metals with titanium. Titanium is a metal that is both lightweight and strong. It also resists corrosion. Selena wants to compare titanium with other metals. She looks at the cell from the periodic table that represents titanium.




Explain what each of the four items in the cell represents. Then, classify titanium as an alkali, alkali earth, or transition metal.

Answers

Ti is a transition metal.

Further explanation

Chemical symbol represent element or compound

The elements are arranged in the periodic system

1. 22

This is the atomic number of Titanium

The Atomic Number (Z) indicates the number of protons of an element

2. Ti

This is the symbol (chemical formula) of titanium

3. 47.90

This is the mass number of Titanium

Mass Number (A) = Number of protons + Number of Neutrons

Atomic Number (Z) = Mass Number (A) - Number of Neutrons

4. Titanium

This is the name of the element

To determine which group, alkaline, alkaline earth or transition it can be seen from the electron configuration

alkali and alkali earth : configuration from orbital 1s-7s

transition : configuration from orbital 3d-6d (Block d)

Electron configuration from Ti : [Ar] 3d²4s²

if we look at the configuration, then Ti is in the d block which is included in the transition metal

How can you tell if an element is a metal or a nonmetal??

Answers

Answer:

Elements to the left of the line are considered metals. Elements just to the right of the line exhibit properties of both metals and nonmetals and are termed metalloids or semimetals. Elements to the far right of the periodic table are nonmetals. The exception is hydrogen (H), the first element on the periodic table.

Explanation:

Answer:

looking at its metallic luster

Explanation:

Elements may be classified as either metals or nonmetals based on their properties. Much of the time, you can tell an element is a metal simply by looking at its metallic luster, but this isn't the only distinction between these two general groups of elements. Most elements are metals.

8.280 μg = __________________________pg

Answers

Answer:

0.2007 nm

3.57 cm

0.01478 g

8280000 pg

Explanation:

1)200.7 pm

1 picometer is equal to 0.001 nanometer.

1 nm = 1000 pm

200.7 pm× 1 nm / 1000 pm  = 0.2007 nm

2)0.000357 hm

1 hectometer is equal to 10,000 centimeter.

1 hc = 10,000 cm

0.000357 hc× 10,000 cm / 1 hc = 3.57 cm

3) 14.78 mg

1 gram is equal to 1000 milligram.

1 g = 1000 mg

14.78 mg × 1 g/1000 mg = 0.01478 g

4)8.280 µg

1 microgram is equal to 10⁶ picogram.

1 µg = 1000000 pg

8.280 µg× 10⁶ pg/ 1µg = 8.280×10⁶ pg or 8280000 pg

Explanation:

Pretty sure protons matter a lot unless in acid and bases but ignore this. Atoms mostly empty space as electrons are reeeeeeeeeeaaaallllllyyyy far apart. number of electrons change it is an ion and neutrons change pretty sure its an isotope. Electrons are stupidly small and fast so they don't really count towards the weight. Most mas comes from neutrons and protons in the nucleus

Answer:

2,3,4,5

1st is wrong cuz if u change the number of proton it would change the atomic number which results in different element

6th is wrong because most mass of the atoms come from neutrons and protons collectively so if it would have said THE ATOMS MASS MOSLTY COMES FROM NUCLEONS then u could mark it right


When 3.00 grams of methane, CH,, reacts according to the balanced equation below, how many molecules of water are produced?
CH, + 202 - CO2 + 2H20

Answers

Answer:

2.41×10²³ molecules of water

Explanation:

Given data:

Mass of methane = 3 g

Molecules of water formed = ?

Solution:

Chemical equation:

CH₄ + 2O₂    →     CO₂  + 2H₂O

Number of moles of methane:

Number of moles = mass/ molar mass

Number of moles = 3 g/ 16 g/mol

Number of moles = 0.2 mol

Now we will compare the moles of water with methane.

               CH₄           :              2H₂O

                  1              :                  2

                0.2            :             2 × 0.2 = 0.4 mol

Molecules of water:

1 mole = 6.022×10²³ molecules of water

0.4 mol ×6.022×10²³ molecules of water / 1mol

2.41×10²³ molecules of water
