The reactant being used up is called limiting reagent as it limits the total amount of product produced.
if 4 units of HCL gives 2 units of Cl therefore
4:2
0.98:x
x=(0.98*2) /4
x=0.49L
Answer:
Amplitude does not effect the wavelength in linear system.
Explanation:
Amplitude:
It is the measure of height from peak to trough.
Wavelength:
It is measure of length from peak to peak.
There is no relation between the amplitude and wavelength but if the system will no more linear then high amplitude can cause the distortion in wave if more frequencies are present. However frequency and wavelength can be related. The wave with higher frequency have shorter wavelength and vise versa.
Frequency:
It is the number of waves passing through a given point in a given time period. It is measure in Hz or s⁻¹
Answer:
λ = 1.43 x 10³ meters (radio waves)
Explanation:
c = f·λ => λ = c/f
λ = wavelength = ?
f = frequency = 2.10 x 10¹⁴ Hz = 2.10 x 10¹⁴ cycles/sec
c = speed of light (vacuum) = 3.0 x 10⁸m/sec
λ = c/f = 3.0 x 10⁸m/sec / 2.10 x 10¹⁴sec⁻¹ = 1.43 x 10³ meters (radio waves)
Answer:
The boiling point wouldn´t be effected. The amount of time it would take to get it to that point would increase
Explanation:
Answer:
- 130.64°C.
Explanation:
- We can use the general law of ideal gas:<em> PV = nRT.</em>
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n and P are constant, and have two different values of V and T:
<em>V₁T₂ = V₂T₁</em>
<em></em>
V₁ = 634.0 L, T₁ = 21.0°C + 273 = 294.0 K.
V₂ = 307.0 L, T₂ = ??? K.
<em>∴ T₂ = V₂T₁/V₁ </em>= (307.0 L)(294.0 K)/(634.0 L) = <em>142.36 K.</em>
<em>∴ T₂(°C) = 142.36 K - 273 = - 130.64°C.</em>
