Answer:
48.67 seconds
Explanation:
From;
1/[A] = kt + 1/[A]o
[A] = concentration at time t
t= time taken
k= rate constant
[A]o = initial concentration
Since [A] =[A]o - 0.75[A]o
[A] = 0.056 M - 0.042 M
[A] = 0.014 M
1/0.014 = (1.1t) + 1/0.056
71.4 - 17.86 = 1.1t
53.54 = 1.1t
t= 53.54/1.1
t= 48.67 seconds
Hence,it takes 48.67 seconds to decompose.
The semi will have the hardest time changing direction because of its mass. The more mass there is, the more effort it takes to accelerate and decelerate as well as change direction.
Monosaccharides are the simplest unit of carbohydrates. They're composed of carbon, hydrogen, and oxygen atoms, and they cannot be broken down further since they are already in their simplest form. Their general formula is (CH2O)n, where n is any number equal or greater than 3.
Answer : The characteristic properties of a substance always remains the same irrespective of the sample being observed is large or small.
Few examples of characteristic properties of any substances includes freezing or melting point, boiling or condensing point, density, viscosity and solubility. They are specific for specific substances and which makes them easily recognizable.
Whereas chemical properties are specific for one substance which chemically transformed into another substances.
K.E. = 1/2 mv2
m= mass
v= volume
and since its measured in Joules, 1 Joule is equal to 1 kilogram-meters squared per second squared.
