Disorder in the universe increases because A. spontaneous changes produce more order in a system.
B. work produces disorder in a system.
C. work produces waste heat, which leaves a system.
D. all of the above

Answers

The correct answer would be the letter C.
A is obviously not right since it says "more order". B is incorrect because work is obligatory to make an order. If A and B are wrong, then D must be wrong. You're left with C, which is the only true statement here.

Explanation:In thermodynamics, a parameter representing the state of disorder of a system at the atomic, ionic, or molecular level; the larger the disorder the upper the entropy. A live of disorder within the universe or of the inconvenience of the energy during a system to try to work.

in the equation 2kclo3 → 2kcl + 3o2, how many moles of oxygen are produced when 3.98 mol of kclo3 decompose completely?

Answers

2 KClO₃= 2 KCl + 3 O₂

2 moles KClO₃ -------> 3 moles O₂
3.98 moles KClO₃ -----> ?

moles O₂ = 3.98 x 3 / 2

moles O₂ = 11.94 / 2

= 5.97 moles of O₂

Technician A says that a soldering gun must be energized for several minutes before it warms up to the melting point of solder. Technician B says that a soldering torch is heated by burning butane gas. Who is right

Answers

Answer:

Both are right

Explanation:

A constant heat must be supplied for several minutes to soldering gun to overcome the melting point of solder. A butane torch is a type of soldering device powered (energised) by the burning of butane gas to melt and solder common metals

Solid samples of the element phosphorus can be white, black, or red in color. The variations in color are due to different(1) atomic masses
(2) molecular structures
(3) ionization energies
(4) nuclear charges

Answers

Answer:

Due to molecular structures.

Explanation:

The different forms of phosphorus (white, black or red) are allotropes of phosphorus.

They differ in molecular structures.

White phosphorus: It has four phosphorus which form a tetrahedral shape.

Black phosphorus : It has orthorhombic structure and due to interlinked six membered rings, it is least reactive.

Red phosphorus: It is formed on heating white phosphorus. It is initially amorphus and turns crystalline on further heating.

Solid samples of the element phosphorus can be white, black, or red in color. The variations in color are due to different Molecular structures.
