A(n) _____ reaction is a self-sustaining series of chemical reactions in which the product of one reaction are the reactsnts in the next reaction.* not a multiple choice *

Answers

Answer 1
Answer:

Answer : The answer is, Chain reaction.

Explanation :

Chain reaction : It is defined as the series of successive elementary processes in which the active intermediate species are consumed and regenerated before the products are obtained.

It is a self-sustaining series of the chemical reactions where the product obtained from one reaction are the reactants in the next reaction and so on.

Hence, a chain reaction is a self-sustaining series of chemical reactions in which the product of one reaction are the reactants in the next reaction.

Answer 2
Answer: it is called a Chain reaction

Whh is most carbon compound poor conductor of electricity

Answers

Explanation:

Most of the carbon compound are convalent in nature and all of the electrons participates in bond formation as such there is no free electrons left to conduct electricity. Moreover carbon compound doesn't readily dissociates to form ions, which conduct electricity. Hence carbon compound are poor conductor of electricity.

Answer:

It is because all the valence electrons are used to form covalent bonds. So, there will be no electrons left to flow the electric current through them.

Carrying capacity is _____.the ratio of predators to prey
the number of populations in a specific area
the number of organisms in a population
the number of organisms an ecosystem can support

Answers

Carrying capacity is the number of organisms an ecosystem can support. It is the maximum size of a population that can survive in the ecosystem. If the animals reach the carrying capacity, the population may crash. As the consequence, the number of animals will decrease due to predators or diseases.

The answer is: number of organisms an ecosystem can support.

A similarity between the separation of powers the system of checks and balances and federalism is

Answers

Hi There! :)

A similarity between the separation of powers the system of checks and balances and federalism is?

A similarity between the separation of powers, the system of checks and balances, and federalism is that they all are meant to keep the federal government from becoming too powerful and tyrannical. 

Answer:

Federalism and Separation of Powers policies seek for decentralised the power and avoid tyranny.

Explanation:

Separation of Powers, according to Montesquieu, is a policy that allow the country to have democracy, because this separation is constituted by three main autonomous powers: judicial, executive and legislative. Each institution can judge others, so this way whole nation power is not concentrated in one point.

In this way, Federalism is alike, because this policy is about having a central government (Federal), and regional governments (States) in a whole political system. So, each regional government has their own rules and freedom to their jurisdiction.

The recipe for pumpkin pie calls for 3 tablespoons of flour and 1.5 cups of sugar for each pie. Which of the following conversion factors would be used to find out how many pies could be made from 7.5 cups of sugar.

Answers

Answer:

5 pumpkin pies could be made with 7.5 cups of sugar.

Explanation:

The conversion factor to solve the problem is:

7.5 cups of sugar*(1 pie)/(1.5 cups of sugar) = 5 pies

a cylinder of oxygen gas is cooled from 300K to 150K by what factor does the average kinetic energy of the oxygen molecules in the cylinder decrease

Answers

Answer:

The factor by which the average kinetic energy of the oxygen molecules in the cylinder decreases is '0.5'.

Explanation:

Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system. It is determined by the equation:

K=(3RT)/(2N_A)

where,

K = Average kinetic energy

R = Gas constant

T = Temperature of the system

N_A = Avogadro's number

Average kinetic energy of oxygen gas molecule at 300 K.

K.E=(3R* 300 K)/(2N_A)..[1]

Average kinetic energy of oxygen gas molecule at 150 K.

K.E'=(3R* 150 K)/(2N_A)..[2]

[1] ÷ [2]

(K.E)/(K.E')=((3R* 300 K)/(2N_A))/((3R* 150 K)/(2N_A))=(300)/(150)=2

K.E'=0.5* K.E

The factor by which the average kinetic energy of the oxygen molecules in the cylinder decreases is '0.5'.

Temperature is a measure of average kinetic energy thus absolute temperature is proportional to average kinetic energy. It should be half: same factor as the temperature.
