Answer:
Thermal decomposition
Explanation:
The thermal decomposition of amino acids could be carried out at different temperatures and at fixed pressure in a reactor. The effect of temperature on products and pathway could be determined by using time as a function. The hydrothermal decomposition of amino acids takes two key paths
1. The delamination of amino acids to produce ammonia and organi acids
2. The decarboxylation to produce amines and carbonic acids.
The thermal decomposition is and effective experiment that could determine the chemical reaction rate and order of reaction, since it's working with time.
Answer:
THE PRESSURE EXERTED BY THE GAS IS THEREFORE 2.88 atm.
Explanation:
Boyle's law states that at constant temperature, the volume of a given mass of gas is inversely proportional to the pressure of the gas.
Mathematically, P1 V1 = P2 V2
Write out the values of the variables given:
P1 = 2.4 atm
V1 = 1.8 L
V2 = 1.5 L
P2 = unknown
Re-arranging the variables by making P2 the subject of the equation, we have:
P2 = P1 V1 / V2
P2 = 2.4 * 1.8 / 1.5
P2 = 2.9=88 atm
Hence, the pressure exerted by the gas is therefore 2.88 atm
Answer:
Explanation:
1. Arteries are the tubes responsible for the movement of blood from the heart to other parts of the body.
2. Power
(a) Work performed
w = mgh = 12 kg × 9.807 m·s⁻² × 15 m = 1800 J
(b) Power level
P = w/t = 1800 J/3 s = 600 W
3. Machine load
The formula for mechanical advantage (MA) is
where
Fₒ = the force of the object
Fₑ = the force exerted to overcome that of the object
Answer:
2.33*10^-15 s
Explanation:
We need to estimate the period of oscillation of an electron that bounced up/down due to the effects of a passing packet of red light. The period of oscillation is the wavelength of the red light divided by the speed of the red light. We know that:
V = f*λ
where V = speed of the red light = 3*10^8 m/s
f = frequency = 1/T where T is the period of oscillation in seconds (s)
λ = the wavelength of the red light = 0.7*10^-6 m
Thus:
V = λ/T
T = λ/V = (0.7*10^-6)/(3*10^8) = 2.33*10^-15 s
