NaCl and AgNO3 react in a double replacement reaction. Which is one of the products of this reaction?

NaNO3
AgClO3
CO2

2Na + 2H2O → 2NaOH + H2

The balanced equation

Answer:

A covalent bond

Explanation:

the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.

Answer:

I recently answered this question. The response I submitted is included below. I beleive my answer should be correct.

Explanation:

Question 1:

C: 48.38g(1mol/12g) = 4.0317 

H: 8.12g(1mol/1.01g) = 8.12

O: 53.5g(1mol/16g) = 3.34375

Divide by the smallest amount (3.34375)

C = 4.0317/3.34375 = 1.206 = 1

H = 8.12/3.34375 = 2.42 = 2

O = 3.34375/3.34375 = 1

Empirical formula = CH2O

Question 2:

Molecular formula = n(empirical formula)

n = molar mass (compound)/molar mass (empirical)

Empirical formula: CH2O

Molar mass of CH2O = 12 + 2x1 + 16 = 30 g/mol

Molar mass of compound: 180.15 g/mol

[tex]n=\frac{180.15g/mol}{30g/mol}= 6[/tex]

Molecular formula = C6H12O6

Answer/Explanation:

Stars spend the majority of their lifespan medling hydrogen nuclei together to form helium. When the hydrogen that in the core of the star begins to run out, the star will start using hydrogen away from its core and this is what causes the star's outer layer to expand and slowly cool down.

From the table showing the data involving the neutralization reaction between HCl and NaOH, the concentration of the HCl solution would be 0.864 M

From the available data:

Volume of acid used = 0.0351 - 0.0131 = 0.022 L

Volume of base used = 0.0575 - 0.0385 = 0.019 L

Concentration of base = 1.00 M

Number of moles of acid and base = 1

Using the equation:                      CaVa/CbVb = Na/Nb = 1

Ca = 1x0.019/0.022 = 0.864 M

The atom that moves at its rms velocity at 100°C with a wavelength of 2.31 * 10 m is : SULPHUR ( s )

To determine the atom we will have to determine the molar mass of the atom

Applying De Broglie equation

λ = h / mv

Vrms = [tex]\sqrt{\frac{3RT}{M} }[/tex]  ---- ( 1 )

Where : λ  = 2.31 * 10⁻¹¹,  R = 8.314 J / k.mol,  T = 373 K, h = 6.626 * 10⁻³⁴ J.s

From equation ( 1 )

M = ( h² Ua ) / 3RT*λ² --- ( 2 )

where : Ua ( mass of an atom ) = 6.022 * 10²³,  h = 6.626 * 10⁻³⁴,  R = 8.314 J / k.mol, λ  = 2.31 * 10⁻¹¹,    T = 373 K

Insert values into equation ( 2 )

M ( molar mass ) = 32 g/mol

Sulphur has a molar mass of 32 g/mol therefore the atom is sulphur.

Hence we can conclude that The atom that moves at its rms velocity at 100°C with a wavelength of 2.31 * 10 m is : SULPHUR ( s ).

The partial pressure is the pressure exerted by a single gas in a volume of the mixture. The partial pressure of dihydrogen is 737.5 mmHg.

According to Dalton's law, the sum of partial pressure of non-reacting gases gives the total pressure of the system.

Given,

Total pressure = 755.0 mmHg

The partial pressure of water = 17.5 mmHg

The partial pressure of dihydrogen = ?

The partial pressure of dihydrogen is calculated as:

[tex]\begin{aligned}\rm p_{total} &= \rm p_{H_{2}O} + p_{H_{2}}\\\\755.0 &=\rm 17.5 + p_{H_{2}}\\\\&= 737.5 \;\rm mmHg\end{aligned}[/tex]

Because gathering it leaves a negative impact on natural habitats.

Answer:

diseases where microbes are the immediate cause are called infectious diseases. Infectious diseases are disorders caused by organisms — such as bacteria, viruses, fungi or parasites. Many organisms live in and on our bodies. They're normally harmless or even helpful.

Answer:

Three principal theories about acid-base are,

1. Arrhenius theory

2. Bronsted-Lowry theory

3. Lux-Flood definition

4. Lewis theory

5. Usanovich definition

1. According to the Arrhenius, acids give up hydrogen ion in aqueous medium and a base give up hydroxyl ion in its aqueous medium. Examples are aqueous solution of HCl, CH3COOH, PhCOOH, and H2SO4. These give up H+ in an aqueous medium. Aqueous solutions of NaOH, Ca (OH)2 are Arrhenius bases.

Arrhenius theory has some limitations. This theory cannot explain the acidic nature of BF3 or basic behavior of NH3. This theory fails to give any explanation about acidity and basicity which does not produce H+ and OH- in their aqueous solutions.

2. According to the Bronsted-Lowry, an acid releases proton and a base accepts proton. NH3 accepts proton and forms ammonium ion, so ammonia acts as a base.

But this theory also has limitations. According to this theory acidic behavior of BF3 still cannot be explained.

3. Lux-Flood describes the acid-base theories based on oxide ion transformation. It gives clear explanation for acid-bases theories of non-protonic system. According to them, a base will donate the oxygen atom and an acid will accept oxygen atom.

4. According to the Lewis theory, acids are those substances which accept electron pair and base are those substances which donates electron pairs. Lewis theory can explain the acidic nature of BF3. In BF3, B is two electrons short to fulfil its octet. So it can accept a pair of electrons from an electron donating substituent. So it is an electron pair acceptor compound and acts as an acid.

Substances which have π electrons can donate electron pair to an electron deficient substance and acts as a base. Ethylene and acetylene is Lewis bases. AlCl3, PCl3 are Lewis acids.

5. According Usanovich, an acid is some chemical species which would react with bases and yields cations or accepts anions or electrons. A base is some chemical species which would react with acids, yield anions or electrons or combine with cations.

The molar mass of the gas that has a mass of 3.82 g and occupies a volume of 0.854 L is 106.66g/mol.

The molar mass of a substance can be calculated by dividing the mass of the substance by its number of moles.

However, the number of moles of the gas in this question needs to be calculated first using the ideal gas law equation:

PV = nRT

Where;

1.04 × 0.854 = n × 0.0821 × 302

0.888 = 24.79n

n = 0.888/24.79

n = 0.036mol

Molar mass of gas = 3.82g/0.036mol

Molar mass = 106.66g/mol

Therefore, the molar mass of the gas that has a mass of 3.82 g and occupies a volume of 0.854 L is 106.66g/mol.

The element that is commonly used to reduce iron oxide would be carbon.

Explanation:

:)

Iron oxide is reduced to a lower oxide or metal by gaseous carbon monoxide or solid carbon.

Reduction is defined as the chemical reaction which involves addition of hydrogen or removal of oxygen or gain of electrons.

For example,

2Na + H2 → 2NaH (addition of hydrogen)

CuO + H2 → Cu + H2O(removal of oxygen)

Fe3+ + e- → Fe2+ (gain of electron)

Above example of reduction reaction is when oxygen reacts with iron to form rust. In this reaction oxygen is reduced because it accepts electrons from iron, which is oxidized.
