Answer:

Wire.

Explanation:

The wire has movable electrons, which moves the charge and the electricity around.

Battery provides the electricity by electrical potential energy, not transport it.

The switch toggles between an open circuit and a closed one, where only the closed one has a full loop of wire to transport electricity.

And the light bulb uses electricity.

Answer:

309.2 ml of oxygen

Explanation:

2 ( 12X2 +Ix 2 ) = S2 ml

O2 = 5 x 16 x 2 = 160 ml

volume of O2 needed = 160×100. 5 / 52 = 309.2 ml

Explanation:

Answer:

they all have the same ionic charge.

Explanation:

Alkaline earth metals are group 2 metals on the periodic table. They are divalent elements because they have two valence electrons and ionize by donating these two valence electrons. Elements in this group have the same numbers of electrons in their outermost shell of their atoms. i.e. they all have the same number of valence electrons and ionic charge.

The density of the sample : 0.827 g/L

In general, the gas equation can be written  

[tex]\large {\boxed {\bold {PV = nRT}}}[/tex]

where  

P = pressure, atm , N/m²

V = volume, liter  

n = number of moles  

R = gas constant = 0.082 l.atm / mol K (P= atm, v= liter),or 8,314 J/mol K (P=Pa or N/m2, v= m³)

T = temperature, Kelvin  

n= 1 mol

MW Neon = 20,1797 g/mol

mass of Neon :

[tex]\tt mass=mol\times MW\\\\mass=1\times 20,1797 =20.1797~g[/tex]

The density of the sample :

[tex]\tt \rho=\dfrac{m}{V}\\\\\rho=\dfrac{20,1797}{24.4}=0.827~g/L[/tex]

or We can use the ideal gas formula ta find density :

[tex]\tt \rho=\dfrac{P\times MW}{RT}\\\\\rho=\dfrac{1\times 20.1797}{0.082\times 298}\\\\\rho=0.826~g/L[/tex]

The mass of the 2.34 × 10²³ atoms of copper is equal to 24.68 grams.

The Avogadro constant can be defined as the proportionality factor that the number of constituent particles in a sample with the amount of substance.

Avogadro’s number can be described as a dimensionless number that represents the number of entities in one mole of any substance. These elementary entities can be molecules, atoms, ions, electrons, or protons, etc.

Avogadro’s constant has a value approximately equal to 6.022 × 10²³ mol⁻¹.

Given, the number of atoms of copper = 2.34 × 10²³

The atomic mass of Cu Copper = 63.5 g/mol

So 6.022 × 10²³ atoms of Cu have mass = 63.5 g

Then 2.34 × 10²³  Cu atoms will have mass = [tex]\frac{63.5 \times 2.34 \times 10^{23}}{6.02 \times 10^{23}}[/tex] = 24.68 g

Therefore, 24.68 grams of Cu are there in 2.34 × 10²³ atoms of Cu.

Explanation:

Answer:

13598 J

Explanation:

Q = m × c × ∆T

Where;

Q = amount of energy (J)

m = mass (grams)

c = specific heat capacity

∆T = change in temperature

m = 65g, specific heat capacity of water = 4.184J/g°C, initial temperature= 100°C, final temperature = 150°C

Q = 65 × 4.184 × (150 - 100)

Q = 271.96 × 50

Q = 13598 J

Hence, 13598 J of energy is required to boil 65 grams of 100°C water and then heat the steam to 150°C.

Explanation:

chemical formulas show what atoms are in a molecule.  In this case there is 1 hydrogen (H), 1 chlorine (Cl), and 3 oxygens (O).  The 3 behind the oxygen is a subscript and tells us that there are 3 oxygen atoms.

Another example is H2O which as 3 atoms. 2 hydrogens (H) and 1 oxygen (O).  This formula has a subscript 2 behind the hydrogen showing that there are 2 hydrogens.

B is a decomposition reaction

The chemical equation which represents decomposition reaction is 2 NaCl[tex]\rightarrow[/tex] 2 Na + Cl₂.

Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.

A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .

The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

Answer: Yes- Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Iron and steel rust when they come into contact with water and oxygen – both are needed for rusting to occur. Rusting is an example of a chemical change. A chemical property describes the ability of a substance to undergo a specific chemical change. A chemical property of iron is that it is capable of combining with oxygen to form iron oxide, the chemical name of rust.

Answer:

117g

Explanation:

Given parameters:

Number of moles = 2moles

Unknown:

Mass of NaCl  = ?

Solution:

To solve the problem, we need to use the expression below;

    Mass of NaCl  = number of moles x molar mass

Molar mass of NaCl  = 23 + 35.5  = 58.5g/mol

So;

Insert the parameters and solve;

     Mass of NaCl  = 2 x 58.5  = 117g

Answer:

The correct option is A

Explanation:

Radium is an atom with the atomic number of 88. It is a metal found in group 2 of the periodic table; meaning that it has two valence electrons in it's outermost shell. As a metal that wants to form an ionic compound, radium would have to lose these two valence electrons to become a divalent positively charged cation (Ra²⁺). Thus, the correct option is A
