Chemistry
1 answer:
Likurg_2 [28]2 years ago
3 0

Answer:

D

Explanation:

Recall that entropy measures the number of microstates in a substance, which is highest in gases, followed by liquids and solids. Hence, entropy increases if the products have more gaseous molecules than the reactants.

  • In reaction one, chlorine gas is converted into solid NaCl, so entropy decreaes.
  • In reaction two, four moles of gas are converted into two moles of gas, so entropy decreases.
  • In reaction three, ice is melted to form water, which has higher entropy. Thus, entropy increases.
  • In reaction four, a liquid is freezed into its solid phase, leading to a decrease in entropy.
  • In reaction five, oxygen gas is converted into solid MgO, so entropy decreases.

In conclusion, the answer is D.

Lost one extensive and one intensive property of a marker ink
emmainna [20.7K]
An extensive property is a property that deals with the amount of a substance. An extensive property of marker ink would be the volume of the ink in the pen. An intensive property is a property about the type of substance you're looking at. So, an intensive property of marker ink would be the color of the ink.

Identify the correct descriptions of beta particles.
FrozenT [24]

Answer:

a. A beta particle has a negative charge. d. A beta particle is a high-energy electron.

Explanation:

Identify the correct descriptions of beta particles.

a. A beta particle has a negative charge. YES. A beta particle is originated in the following nuclear reaction: ¹₀n ⇒ ¹₁H + ⁰₋₁e (beta particle.)

b. A beta particle contains neutrons. NO. It is a electron originated in the nucleus.

c. A beta particle is less massive than a gamma ray. NO. Gamma rays don't have mass while a beta particle has a mass which is half of one thousandth of the mass of a proton.

d. A beta particle is a high-energy electron. YES. Beta particles are nuclear originated hig-energy electrons.

Now examine salts containing the halide anions, cl- and br-. Most of these are soluble. What two cations listed lead to insolubl
tatiyna

Ag+ and Pb+2 are two cations that are suggested as producing insoluble halide salts when studying salts containing the halide anions, cl- and br-. First, the charge's number is provided.

Neutral binary salts, also referred to as halide salts, are mixtures of metals and non-metals. The non-metal behaves in a reduced oxidation state at all times. They are the outcome of mixing a hydroxide and hydracid. halide salts of haloids are produced by the reaction of a hydroxide and a hydracid.

Ions are cations with positive charges. They emerge when the electrons of an elemental metal are lost. However, they don't lose any protons; they only lose one or more electrons. To denote a cation, the charge is superscripted following the element name or chemical formula.
