You will have to check the datasheets for both the CMOS gate and the LED, then if the CMOS gate's rated output current is enough to light the LED you will need to do a little arithmetic using Ohm's law to calculate the resistor to put in series with the LED to limit current and avoid damaging the parts.

Is cmos is static complementary logic?
No. CMOS stands for Complementary Metal Oxide Semiconductor. Basically, it is a transistor formed by semiconductor bar to which an electrode (gate) attaches. This gate is isolated from the bar. A voltage on the the gate will create an electrostatic field that will prevent the current to circulate along the semiconductor bar. CMOS transistors are mostly used for digital (binary) application and consume very little current.

What is a cmos gate?
A CMOS gate is a logical switch used in electronics. CMOS stands for Complimentary Metal Oxide Silicon. These types of semiconductors have a very high input impedance, are very sensitive use low current and work over a larger range of voltage. The alternative is TTL(Transistor to Transistor Logic) which work at 5volts only and draw higher currents. A gate, is a switch that changes state (on/off) depending on the logic voltage levels applied to it's inputs.
What is the significance of high impedance state in tri-state gates?
This is a state that disconnects the gate from the line it drives so that another gate can connect to it and drive it instead. This permits sharing so that multiple sources can drive common lines without fighting and/or damaging each other.
What is voltage of TTL circuit?
CMOS gate circuits have input and output signal specifications that are quite different from TTL. For a CMOS gate operating at a power supply voltage of 5 volts, the acceptable input signal voltages range from 0 volts to 1.5 volts for a "low" logic state, and 3.5 volts to 5 volts for a "high" logic state. "Acceptable" output signal voltages (voltage levels guaranteed by the gate manufacturer over a specified range of load conditions) range from 0 volts to 0.05 volts for a "low" logic state, and 4.95 volts to 5 volts for a "high" logic state:It should be obvious from these figures that CMOS gate circuits have far greater noise margins than TTL: 1.45 volts for CMOS low-level and high-level margins, versus a maximum of 0.7 volts for TTL. In other words, CMOS circuits can tolerate over twice the amount of superimposed "noise" voltage on their input lines before signal interpretation errors will result.CMOS noise margins widen even further with higher operating voltages. Unlike TTL, which is restricted to a power supply voltage of 5 volts, CMOS may be powered by voltages as high as 15 volts (some CMOS circuits as high as 18 volts). Shown here are the acceptable "high" and "low" states, for both input and output, of CMOS integrated circuits operating at 10 volts and 15 volts, respectively:The margins for acceptable "high" and "low" signals may be greater than what is shown in the previous illustrations. What is shown represents "worst-case" input signal performance, based on manufacturer's specifications. In practice, it may be found that a gate circuit will tolerate "high" signals of considerably less voltage and "low" signals of considerably greater voltage than those specified here.Conversely, the extremely small output margins shown -- guaranteeing output states for "high" and "low" signals to within 0.05 volts of the power supply "rails" -- are optimistic. Such "solid" output voltage levels will be true only for conditions of minimum loading. If the gate is sourcing or sinking substantial current to a load, the output voltage will not be able to maintain these optimum levels, due to internal channel resistance of the gate's final output MOSFETs.Within the "uncertain" range for any gate input, there will be some point of demarcation dividing the gate's actual "low" input signal range from its actual "high" input signal range. That is, somewhere between the lowest "high" signal voltage level and the highest "low" signal voltage level guaranteed by the gate manufacturer, there is a threshold voltage at which the gate willactuallyswitch its interpretation of a signal from "low" or "high" or vice versa. For most gate circuits, this unspecified voltage is a single point:
Why is a TTL logic gate faster than a CMOS logic gate?
The switching time (on and off) of the TTL logic gate is very fast in comparison with CMOS logic gate. However, they could not tolerate higher range of power supply.

What is the importance gate capacitance in CMOS device?
For the gate to change state, the gate capacitance must be charged or discharged. Since the transistor driving the gate has a certain amount of output impedance (resistance), this together with the gate capacitance forms an RC network. The gate capacitance must charge through the driver's output impedance, and this takes time. So, gate capacitance limits the maximum speed at which the device can be operated. Decrease the capacitance, and you can clock the device faster!
