Answer:
Alkane
Explanation:
Definition of Alkane "any of the series of saturated hydrocarbons including methane, ethane, propane, and higher members. (google dictionary)"
CH4 is methane.
Answer:
false
Explanation:
i had the same thing to do
I think the effect of increasing temperature would be; the equilbrium will shift back wards. Increase in temperature favors backward reaction since the forward reaction is exothermic and the backward reaction is endothermic. Therefore, the equilibrium will shift back wards, and there will be more reactants (H2 and Cl2) compared to the products
The resulting number should have three significant figures, since both multipliers have 3 significant figures. The answer is as follows:

601.02
Taking 3 significant figures:

What is the wavelength of 101-WCHEM its broadcasting frequency is 101.9 megahertz?
The relationship between the frequency of an electromagnetic wave and its wavelength is given by this formula:
c = λ * f
where, c stands for the speed of light, λ is the wavelength and f is the frequency.
According to our problem:
f = 101.9 megahertz
λ = ??
And we can search for the value of the speed of light:
c = 2.99 * 10⁸ m/s
To solve the problem we have to convert MHz into cycles/sec
1 MHz = 1 000 000 Hz = 1 * 10⁶ Hz
1 Hz = 1 cycle/sec
f = 101.9 MHz * (1 * 10⁶ Hz) / (1 MHz) = 1.019 * 10⁸ Hz = 1.019 * 10⁸ cycles/sec
Our unknown is the wavelength. Let's solve our formula for λ:
λ = c / f
Replacing:
λ = (2.99 * 10⁸ m/s) / ( 1.019 * 10⁸ cycles/s)
λ = 2.93 m
The wavelength of 101-WCHEM is 2.93 m.
If we want to convert it to cm:
100 cm = 1 m
λ = 2.93 m * 100 cm/(1 m) = 293 cm
The wavelength of 101-WCHEM is 293 cm.
