Naily [24]3 years ago
7 0
Earth's outer core is a fluid layer about 2,400 km (1,500 mi) thick and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. Its outer boundary lies 2,890 km (1,800 mi) beneath Earth's surface. ... Unlike the inner (or solid) core, the outer core is liquid. Hope this helps

The initial concentration of reactants in a first order reaction is 0.27 M. The rate constant for the reactio is 0.75 s^-1. What
lawyer [7]

Answer:

Final concentration = 0.019 M

Explanation:

Initial Concentration [A]o = 0.27M

Rate constant, k = 0.75 s^-1

Final concentration [A] = ?

Time, t = 1.5s

The relationship between the variables is given by the equation;

ln[A] = ln[A]o - kt

ln[A] = ln(0.27) - (0.75)(1.5)

ln[A] = - 1.309 - 1.125

ln[A] = - 2.434

[A] = 0.019 M

Sergio039 [100]

"Polysaccharide carbohydrate" comprises an S. pneumoniae capsule.

<u>Option:</u> C

<u>Explanation:</u>

The lengthy sequences of carbohydrate molecules, primarily polymeric carbohydrates constructed of units of monosaccharides linked together through glycosidic connections, understood as Polysaccharides. This carbohydrate can respond to water by catalyzing amylase enzymes, which generate component sugars.

A major human pathogen is Streptococcus pneumoniae or pneumococcus. The virulence is primarily due to its polysaccharide envelope, which protects it from the recipient immune response, and this has led to comprehensive study of the shell.
