What is the period of a water wave with a frequency of 0.5 Hz?
Oxana [17]
T is the time it takes for one complete oscillation , it is measured in seconds. All waves, including sound waves and electromagnetic waves , follow this equation. For example, a wave with a time period of 2 seconds has a frequency of 1 ÷ 2 = 0.5 Hz. A sound wave has a time period of 0.0001 seconds.

State of matter
Nina [5.8K]

Answer:

H₂

Explanation:

To solve this question we must find, as first, find the molar mass of the homonuclear diatomic gas using Graham's law. With the molar mass we can identify this gas

<em>Graham's law:</em>

\frac{V_a}{V_b} =\sqrt{\frac{m_B}{m_A} }

<em>Where V is the speed of the gases and m the molar mass of those:</em>

<em>As Va is 3.98 times Vb (And mB is molar mass of oxygen gas = 32g/mol)</em>

3.98 =\sqrt{\frac{32g/mol}{m_A} }

15.84 = 32g/mol / mA

mA = 2.02g/mol

As is a homonuclear diatomic gas, the molar mass of the atom is 1.01g/mol. Thus, the gas is:

Potassium hydroxide, KOH, is considered a _____________ in an acid-base reaction because it ___________ a hydrogen ion to/from t
soldi70 [24.7K]
<span>Answer: Potassium hydroxide, KOH, is considered a BASE in an acid-base reaction because it ACCEPTS a hydrogen ion from the other reactant.

According to </span><span>Brønsted–Lowry acid–base theory, Base is a specie which accepts proton (H</span>⁺) while, Acid is a specie which donate proton.

Bases may contain a negative charge or lone pair of electrons, while, Acids contain positive charge or a neutral atom with incomplete octet.

In given statement KOH is acting as a base because it contains a negatively charged hydroxyl group which can accept proton from a acid, i.e. 

                                    KOH    →     K⁺  +  OH⁻

Reaction of OH⁻ with any acid,

                         K⁺    +   OH⁻  +   HCl      →       H₂O   +   KCl

The ideal gas constant, R has several different values that could be used. Which quantity causes these differences? pressure tem
Blababa [14]

Answer : The correct option is, pressure.

Explanation :

The ideal gas equation is,

PV=nRT

where,

P = pressure of the gas

V = volume of the gas

n = number of moles of gas

T = temperature of the gas

R = gas constant

The value of 'R' has several different values which are :

R=0.08205L.atm/mol.K

R=8.3145L.kPa/mol.K

R=8.3145J/mol.K 

R=1.987cal/mol.K

R=0.08314L.bar/mol.K

That means, the value of 'R' is different due the change in the pressure value and all the variables (temperature, volume and moles) are constant.

Hence, the correct option is, pressure.
