Explanation:

a. direct

Amplitude and wavelength are the property of the waves. These both are directly related to each other. Thus, option A is correct.

Amplitude is the measure of the wavelength that is estimated from the peak or crest to the trough of the wave. Wavelength is the measurement of the length of the wave from one peak to the crest of another wave.

Though there is no relationship between the wavelength and amplitude of the waves they can be said to have direct relation as wavelength and frequency are indirectly related.

Therefore, option A. direct relation is correct.

Answer:asexual- Energy is not required to find a mate. Offspring are genetic clones. A negative mutation can make asexually produced organisms susceptible to disease and can destroy large numbers of offspring. Some methods of asexual reproduction produce offspring that are close together and compete for food and space.

Explanation:During sexual reproduction the genetic material of two individuals is combined to produce genetically diverse offspring that differ from their parents.

Answer:

The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles K2SO4, or 174.2592 grams.

Explanation:

The potassium sulphate( [tex]K_{2} SO_{4}[/tex] )contain 940.95 gram in 5.4 moles.

A mole is described as the quantity of a material that includes precisely 6.02214076 X [tex]10^{23}[/tex] of the substance's elementary constituents.

Given data:

Mole = 5.4

Molar mass = 174.25 g/mol

Mass = ?

Mole can be calculated by using the formula:

Mole = mass / molar mass

Put the value of given data in above equation.

Mass = Mole × molar mass

Mass = 5.4 mole × 174.25 g/mol

Mass = 940.95 gram

Therefore, there are 940.95 gram in [tex]K_{2} SO_{4}[/tex]

The first step in the digestive process happens before we even taste food. Just by smelling that homemade apple pie or thinking about how delicious that ripe tomato is going to be, you start salivating — and the digestive process begins in preparation for that first bite.

Almost all animals have a tube-type digestive system in which food:

enters the mouth

passes through a long tube

exits the body as feces (poop) through the anus

Along the way, food is broken down into tiny molecules so that the body can absorb nutrients it needs:

Protein must be broken down into amino acids.

Starches break down into simple sugars.

Fats break down into into fatty acids and glycerol.

Answer:

For pure water, the values of [H3O+] and [OH-] are equal and thus their values are both 1.0 x 10-7. If there is an equal amount of acid and base present in any solution, the solution is called "neutral" and the pH of the solution is 7. ... The sum of the pH and pOH must always equal 14.

Explanation:

The equation of the reaction;

KHSO4(aq) + KOH(aq) -------> K2SO4(aq) + H2O(l)

Number of moles of KHSO4 = 49.6 g/136.169 g/mol = 0.36 moles

Since the reaction is in a mole ratio of 1:1, 0.36 moles of K2SO4 is produced.

Number of moles of KOH = 25.3 g/56.1056 g/mol = 0.45 moles

Since the reaction is 1:1, 0.45 moles of K2SO4 is produced

Hence K2SO4 is the limiting reactant.

Mass of K2SO4 formed = 0.36 moles of K2SO4 * 174.26 g/mol = 62.7 g

So;

1 mole of KHSO4 reacts with 1 mole of KOH

0.36 moles of KHSO4 reacts with 0.36 * 1/1 = 0.36 moles of KOH

Amount of excess KOH = 0.45 moles - 0.36 moles = 0.09 moles

Mass of excess KOH = 0.09 moles * 56.1056 g/mol  = 5 g of excess KOH

Answer:

C2H3Br + O2 → CO2 + H2O + HBr

Explanation:

The term balancing of chemical reaction equation has a unique meaning in chemistry. What it actually means is to ensure that the number of atoms of each element on the left hand side of reaction equation becomes equal to the number of atoms of the same element on the right hand side of the reaction equation.

When we look at the equation; C2H3Br + O2 → CO2 + H2O + HBr, the number of atoms of each element on the left and right hand sides of the given equation are not the same hence the equation is unbalanced.

If we look at the equation; 2C2H3Br + 5O2 → 4CO2 + 2H2O + 2HBr, the number of atoms of each element on both sides of the reaction equation are now equal, thus the later equation is the balanced version of the former.

Answer:

[CH₃COOH] = 1.70 M

Explanation:

When we talk about concentration we can determine Molarity

Molarity determines the moles of solute that are contained in 1L of solution.

In this case our solute is the acetic acid.

M = mol/L

M = 0.99 mol /0.58L → 1.70 M

We can also make a rule of three

In 0.58 L of solution we have 0.99 moles of solute

In 1 L of solution we may have (1 . 0.99) / 0.58 = 1.70 moles

Acetic acid is a weak acid, partially dissociated in water.

CH₃COOH  +  H₂O  ⇄  CH₃COO⁻  +  H₃O⁺     Ka

O-18 is used as a tracer in many hydrologic studies. It is most often used as a component in a mixing-model and hydrograph separation, as O-18 acts conservatively and is applied naturally and uniformly over broad areas. O-18 can be used when different sources (old water/new water) have different isotopic values.

Answer:

6.31g/mol

Explanation:

Using the ideal gas equation;

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas law constant (0.0821 Latm/molK)

T = temperature (K)

Mole (n) = mass (m)/molar mass (Mm)

* Mm = m/n

Also, density (p) = mass (m) ÷ volume (V)

PV = nRT

Since n = M/Mm

PV = M/Mm. RT

PV × Mm = m × RT

Divide both sides by V

P × Mm = m/V × RT

Since p = m/V

P × Mm = p × RT

Mm = p × RT/P

Mm = 0.249 × 0.0821 × 293/0.95

Mm = 5.989 ÷ 0.95

Mm = 6.31g/mol

P. Cyanide is toxic to clover plants because they use cytochrome c oxidase for electron transport in the mitochondria.

The correct option is B.

Various bacteria, fungi, and algae have the ability to produce cyanides. Tapioca, spinach, willow shoots, almonds, string beans, fruit seeds, and car fumes are other items that contain cyanides.

Smoking cigarettes and the byproducts of the combustion of synthetic fibers, including plastics, contain cyanide. Combustion products are chemicals that are released while combustion. The paper production, textiles, and plastics all use cyanide. The chemicals used it to develop pictures include it. Unfortunately, cyanide is not like other materials. By utilizing this approach, you simply cannot develop a natural tolerance to cyanide.
