TRUE.
Taste and smell senses are separate senses with their own receptor organs yet they are intimately entwined. Tastants, chemicals in foods are detected by taste buds which consist of special sensory cells.. When stimulated, these cells send signals to specific areas of the brain which then makes us conscious of the perception of taste. Also specialized cells in the nose pick up odorants, airborne odor molecules. Odorants stimulate receptor proteins found on hairlike cilia at the tips of the sensory cells, a process that initiates a neural response.

Hydrogen sulfide, H2S, and hydrogen chloride, HCl, are both gases at temperatures above –50 °C.
vladimir1956 [14]

Explanation:

A gas at higher temperature is able to gain more heat from the environment/surroundings and has more kinetic energy to diffuse at a faster rate.

Hence a temperature at -20°C is more ideal.

Molar mass of H2S = 34.07g/mol

Molar mass of HCl = 36.45g/mol

Since H2S has a smaller molar mass, the same number of moles of H2S gas will diffuse faster as compared to the same number of moles of HCl gas.

Hence the answer is Hydrogen sulfide at -20°C. (D)

A car is traveling with an initial velocity of 15 m/s when the driver decides to go faster by accelerating at 5 m/s squared for
tiny-mole [99]

Answer:

x = 400 [m]

Explanation:

To solve this problem we must use the following kinematics equations, first, we find the final speed, and then we proceed to find the distance traveled.

v_{f}=v_{i} +(a*t)\\

where:

Vf = final velocity [m/s]

Vi = initial velocity = 15 [m/s]

a = acceleration = 5 [m/s^2]

t = time = 10 [s]

Note: the positive sign in the Equation indicates that the car is accelerating, i.e. its speed is increasing.

<u>Now replacing</u>

Vf = 15 + (5*10)

Vf = 65 [m/s]

Now using the second equation:

v_{f} ^{2}= v_{i} ^{2}+(2*a*x)

where:

x = distance traveled [m]

x = (65^2 - 15^2)/ (2*5)

x = 400 [m]
