Explanation:

Higher the frequency smaller will be the wavelength. Higher frequency have shorter wavelength and lower frequency waves have larger wavelength. Also, Beats are formed by the superposition of two waves with slightly different frequencies but with similar amplitudes. In time, waves switch between constructive interference and disruptive interference, giving the resultant wave a time-varying amplitude.

The true statement about these two waves is option C. Wave A has a lower pitch.

Sound waves when traveling via air are known as longitudinal waves .

Since sound passes via air, the particles of air does not vibrate in a transverse manner. Also, amplitude controls the loudness while on the other hand, frequency controlled the pitch. That means, the more frequent the higher should be the pitch.

Therefore, the correct option is C.

Answer:

Calcium carbonate (CaCO3), essentially, is an ionic compound having the bivalent calcium and carbonate ions.

But the carbonate anion is a polyatomic species. The carbon atom is bonded to all the three oxygen atoms by covalent bonds - two carbon-oxygen single bonds and one carbon-oxygen double bond. Owing to resonance, the three carbon-oxygen bonds are also of equal length in the carbonate anion.

Any salt having a polyatomic ion invariably contains both ionic and covalent bonds.

Answer:

Although they have the same mole, they have different molar masses because of their chemical composition.

1. Iron: 55.845 g/mol

2. Sodium Chloride: 58.44 g/mol

3. Sodium Bicarbonate (NaHCO3): 84.006 g/mol

4. Aluminum: 26.982 g/mol

Explanation:

Use the periodic table to determine their molar masses by looking at the atomic mass of each element

1. Given

2. 22.99 (Na) +35.45(Cl) =58.44

3. 22.99(Na)+1.008(H)+12.011(C)+[3*15.999 (O)] = 84.006

Notice how O is multiplied by 3 because there are 3 atoms of oxygen

4.Given

Answer: To calculate the number of molecules and atoms in a water drop, you need to know the chemical formula of water. There are two atoms of hydrogen and one atom of oxygen in each water molecule, making the formula H 2 O. So, each molecule of water contains 3 atoms. Molar Mass of Water

[tex]\boxed {\boxed {\sf About \ 2.96 \ moles \ of \ Argon}}[/tex]

Explanation:

To convert from grams to moles we must use the molar mass, which is found on the Periodic Table.

Use the molar mass as a ratio.

[tex]\frac{39.9 \ g \ Ar}{1 \ mol \ Ar}[/tex]

Multiply by the given number of grams: 118

[tex]118 \ g \ Ar *\frac{39.9 \ g \ Ar}{1 \ mol \ Ar}[/tex]

Flip the fraction so the grams of argon will cancel each other out.

[tex]118 \ g\ Ar * \frac{1 \ mol \ Ar}{39.9 \ g \ Ar}[/tex]

[tex]118 * \frac{ 1 \ mol \ Ar}{39.9 \ g \ Ar}[/tex]

[tex]\frac {118 \ mol \ Ar }{ 39.9 }[/tex]

[tex]2.95739348 \ mol \ Ar[/tex]

The original measurement of grams had 3 significant figures, so our answer must have 3 sig figs.

For the number we calculated, that is the hundredth place. The 7 in the thousandth place tells us to round the 5 to a 6.

[tex]2.96 \ mol \ Ar[/tex]

There are about 2.96 moles of Argon in 118 grams.

Answer:

712 moles of Hg are produced

Explanation:

Based on the reaction:

2HgO → 2Hg + O₂

Where 2 moles of HgO reacts producing 2 moles of Hg and 1 mole of O₂

To solve this question we need to find the moles of Hg produced, then, using its molar mass:

Moles Hg:

3.55mol HgO * (2 mol Hg / 2 mol HgO) = 3.55 mol Hg

Grams -Molar mass Hg: 200.59g/mol-:

3.55mol Hg * (200.59g/mol) =

712 moles of Hg are produced

Option B is correct. Phosphates are formed when phosphorus reacts with Oxygen

A phosphate group is formed from the bonding of four oxygen atoms to a phosphorous atom. The chemical reaction is as shown:

P + O₄ -> PO₄

P is the symbol of phosphorus

O is the symbol of oxygen

When both elements combine, they form phosphates.

Hence we can conclude that Phosphates are formed when phosphorus reacts with Oxygen

Answer:

1.64 moles O₂

Explanation:

Part A:

Remember 1 mole of particles = 6.02 x 10²³ particles

So, the question becomes, how many  '6.02 x 10²³'s are there in 9.88 x 10²³ molecules of O₂?

This implies a division of given number of particles by 6.02 x 10²³ particles/mole.

∴moles O₂ = 9.88 x 10²³ molecules O₂ / 6.02 x 10²³ molecules O₂ · mole⁻¹ = 1.64 mole O₂

Part B needs an equation (usually a combustion of a hydrocarbon).

Bacteria reproduces asexually and produce genetically identical offspring. They produces a large number of offspring quickly and all will be uniform.

Binary fission is the asexual method of reproduction in  bacteria. Asexual reproduction creates clones of the original parent, which results in kids that are genetically identical to the parent.

Asexual reproduction allows for the rapid production of vast numbers of children by a single person. Asexual reproduction is a successful method of reproduction in a stable or predictable environment since all the children will be suited to that environment.

Asexually reproducing organisms may be at a disadvantage in an unstable or unpredictable environment since all of the progeny are genetically similar and might not have the genetic diversity to survive in new or changing settings.
