Answer:

b. the ability to maintain homeostasis.

Explanation:

Homeostasis is the ability of the body to regulate its temperature within a given range of values. This is majorly a property of living thigns with a constant body temperature, e.g human being. Not all living thigns have this characteristics, like if you compare man and plants.

At 150°C the decomposition of acetaldehyde CH3CHO to methane is a first order reaction. If the
Crank

The decomposition time : 7.69 min ≈ 7.7 min

<h3>Further explanation</h3>

Given

rate constant : 0.029/min

a concentration of  0.050 mol L  to a concentration of 0.040 mol L

Required

the decomposition time

Solution

The reaction rate (v) shows the change in the concentration of the substance (changes in addition to concentrations for reaction products or changes in concentration reduction for reactants) per unit time

For first-order reaction :

[A]=[Ao]e^(-kt)

or

ln[A]=-kt+ln(A0)

Input the value :

ln(0.040)=-(0.029)t+ln(0.050)

-3.219 = -0.029t -2.996

-0.223 =-0.029t

t=7.69 minutes

With the kinetic energy of a sample increases the____ will also increase
klemol [59]

Answer:

Its Temperature.

Explanation:

  • Kinetic energy is the energy possessed by a body while in motion. Potential energy on the other hand is the energy possessed by a body based on its position.
  • Kinetic energy of a body is determined by the equation; K.E = 3RT/2;
  • From the equation, kinetic energy is directly proportional to the temperature of the system and therefore an increase in the kinetic energy of a sample causes an increase in temperature of the system.
