Yes, it is a liquid because a solid is a state of matter with a fixed volume and shape; and Gases take both the shape and the volume of their container; and liquid is the one that takes the shape of their container but not necessarily the volume.
Answer:
The empirical formula for C12 H24 O6 is C2 H4 O.
Answer:
Structural formula
Explanation:
This is because structural formula is use to show or indicate chemical bonds that are present between atoms of molecules. structural formula comprises of symbols that represent the atoms which are connected by short lines which indicate the presence chemical bonds which could be single line, double lines or even triple lines.
<u>Given:</u>
Frequency (ν) = 319 THz
<u>To determine:</u>
The wavelength corresponding to the given frequency
<u>Explanation:</u>
Wavelength (λ) and Frequency(ν) are related as:
λ = c/ν
where c = speed of light = 3*10⁸ m/s
Now:
SI unit of frequency is Hertz (Hz) also expressed as cycles per second
i.e 1 Hz = 1 s⁻¹
1 Terahertz (THz) = 10¹² Hz
therefore the given frequency ν = 319 *10¹² s⁻¹
λ = 3 * 10⁸ ms⁻¹/319 *10¹² s⁻¹ = 940 * 10⁻⁹ m
since 1 nanometer (nm) = 10⁻⁹ m
The wavelength is λ = 940 nm
Ans: The infrared wavelength = 940 nm
Answer:
Explanation:
Since this problem is incomplete, let us give a simple explanation to solve it.
In any reaction, we always have reactants that are in short supply and those that are in excess.
A reactant in short supply in a reaction is called the limiting reagent. This reactant will usually determine the extent of the reaction. When it is used up, the reaction will stop and will not proceed further.
To solve for the limiting reagent, convert the given mass to number of moles. Always work with number of moles.
Then write the balanced reaction equation.
Compare the moles from the balanced equation to that obtained. The reacting specie that is lesser in proportion is the limiting reagent
To solve the second part;
Compare the number of moles of the limiting reactant to that of the product i.e H₂O;
Use this number of moles to find mass;
Mass of H₂O = number of moles x molar mass
