The law of conservation of mass states that in a chemical reaction mass is neither created nor destroyed.

Answer:

Beta decay changes the atomic number of the nucleus by increasing the number of protons, by decreasing the number of neutrons while leaving the atomic mass essentially the same.

Answer:

i think its replacement

Explanation:

By definition, the correct answer is the second option: the reaction is a replacement.

A simple substitution reaction or simple displacement reaction, called single-displacement reaction, is a reaction in which an element of a compound is substituted by another element involved in the reaction.

The starting materials are always pure elements and an aqueous compound. And a new pure aqueous compound and a different pure element are generated as products.

The general form of a simple substitution reaction is:

AB + C → A +BC

where C and A are pure elements; C replaces A within compound AB to form a new co, placed CB and elementary A.

A single-displacement reaction is characterized by a place of exchange of cations or anions with another to form a new product. A begins as an ion in the solution and appears elementally in the reaction products. In case of reagent C it starts in its elemental form and ends as an ion in an aqueous state forming compound BC.

In this case, it is a single replacement reaction where 1 atom of Zinc metal displaces 2 H⁺ ions from the hydrochloric acid to form hydrogen gas and zinc chloride, a salt.

Finally, the correct answer is the second option: the reaction is a replacement.

Answer:

2,780,000mg

Explanation:

Using the Metric Staircase photo provided, you can calculate how many mg there are in 2.78 kg by simply moving the decimal point six places to the right, since the "Kilo" step takes six places to move to the "Milli" step.

2.78 kg

---------------

2 7 8 0 0 0 0 .

we can see that the decimal point is moved to the right six places.

Answer:

2,780,000mg

Answer:

No, there is not because it would form H2 instead of methane if hydrogen bonded with itself.

Explanation:

from the shape of methane which is tetrahedral it's evident there's no hydrogen bond only C-H bond.

The chemical formula of methane is [tex]CH_4[/tex] but: C. No, there is no bond between any of the hydrogen atoms because it would form [tex]H_2[/tex] instead of methane if hydrogen bonded with itself.

A chemical bond is defined as the forces of attraction existing between ions, crystals, atoms or molecules and they are mainly responsible for the formation of chemical compounds.

This ultimately implies that, a chemical bond refers to a force holding two or more atoms together and binding ions, crystals, or molecules together, in order to form a chemical compound.

Methane comprises of an atom of carbon and four (4) atoms of hydrogen.

Basically, hydrogen only shares a single (one) valence electron with carbon but not itself (hydrogen atoms) to form methane because of the [tex]sp^3[/tex] hybridization.

Hence, there is no bond existing between any of the four (4) hydrogen atoms because it would form [tex]H_2[/tex] instead of methane ([tex]CH_4[/tex]), if hydrogen bonded with itself.

Answer:

270 sec . ( = 4 min . 30 sec . ) Explanation: Any radio wave is moving at the speed of light, regardless of the frequency, so the frequency should be superfluous information. The speed is light is close to 300 , 000 k m s I take the distance you are given, to be 8.2 ⋅ 10 7 k m (since 8.2 ⋅ 107 k m doesn't make good sense - it's less than 1000 km) i.e. 82 , 000 , 000 km.

Before we actually compute this, we can notice that this is a little more than half the distance of the earth from the sun (150 mill. km), a distance the light uses 500 sek. = 8 min 20 sec. to travel, so we should get about 4 1 2 min for the radio wave to reach Mars from the earth.

Actual calculation: 82 , 000 , 000 km/300 , 000 k m s = 820 3 s = 273.3 s As the distance is given with 2 significant figures, we round this off to 270 sec = 4 min 30 sec.

Explanation:

Answer:

Explanation:

The elements in the long form of periodic table are classified into four blocks. They are s, p, d and f-block elements. The classification is based on the name of orbitals which receive the last electron. The elements in which the valence shell electron enters the s-orbital are called s-block elements.

Answer:

1. 50 km/hr

2. 5 m/s

3. 180 km/hr 50 m/s

4. 30.56 m/s

5. 11.4 km/hr

Explanation:

#1 500 km/ 10 hours = 50 km/hr

#2 100 m/ 20 s = 5 m/s

#3 540 km/3 hrs = 180 km/hr

180 km/1 hr x (1000 m/ 1 km) x (1 hr/ 60 minutes) x (1 minute/ 60 seconds) = 50 m/s

Answer:

# of Proton: 48

# of Electron: 48

# ofNeutron: 64

Explanation:

The atomic number of cadmium is 48.

∴  atomic number = protons = electrons = 48.

Neutrons = mass number - atomic number

∴ Neutrons = 112 - 48 = 64.

⇒ number of protons= 48; neutrons= 64; electrons=48

Answer:

The mass number is the sum of protons and neutrons. This means to find the number of neutrons you subtract the number of protons from the mass number.

The reactivity of fluorine can be explained from molecular orbital theory with the calculation of the bond order.

The molecular orbital theory is assigned to explain the movement of the electrons in the bonding and anti-bonding orbitals.

The number of atom in the bonding and anti-bonding atomic orbits results in the elucidation of the bond order for the element.

The bond order and reactivity are inversely proportional to each other. The higher bond order depicts the presence of stronger bonds between the molecules and lower reactivity.

The bond order of fluorine atom is elucidated from the molecular orbital theory. The bond order of fluorine atom is 1, that explains the high reactivity of fluorine.

Sodium chloride solution contain free electron to conduct electricity. But in solution is not acid or basic media that is why not active in litmus paper

Explanation:

The sodium chloride solution a good conductor of electricity but does not have any effect on litmus paper because sodium chloride solution have free electron to conduct electricity. But in solution is not acid or basic media.

The sodium atoms and chlorine atoms separate when sodium chloride dissolves in water due to the influence of the water molecules. They are free to move as positively and negatively charged ions in the water. This charge separation enables the solution to conduct electricity.

Because cane sugar is a covalent compound bonded by electron sharing, a solution of cane sugar does not conduct electricity. There are no ions in the solution to conduct electrical charges across the solution.

Thus, sodium chloride solution have free electron to conduct electricity. But in solution is not acid or basic media.
