A scientist in London and a scientist in California both conducted independent investigations that produced similar results. Wha

t does this mean about the data that was collected? The findings are considered stronger and more reliable because they were repeated. The scientists will have to compete for the credit for this discovery. The scientific community will vote on the name of any resulting theory, in order to keep things fair. The findings are automatically promoted to a law because they were proven by two different scientists.

Answer:

A) The findings are considered stronger and more reliable because they were repeated

Explanation:

Because the same thing was experimented twice, and the final result was still the same, it means this is more of a strong and reliable experiment outcome.

Imine formation from an aldehyde and an amine proceeds reversibly under slightly acidic conditions. The reaction is reversible d
Lostsunrise [7]

Answer:

Imine can be isolated from the reaction mixture as water is continuously removed from the reaction chamber

Explanation:

In this reaction, a non -aqueous solvent  is not used (not mentioned in the question). Thus, we can say that there is continuous removal water under suitable reacting conditions and hence the imine formed is left behind.

A small gas cylinder of Helium can be used to fill many more balloons than would fit inside it. Explain how this works, in your
Fudgin [204]
<h2>Gas Molecules Move in Random Motion </h2>

Explanation:

  • According to the property of an ideal gas the volume occupied by the gas molecules themselves is negligible as compared to the volume occupied by the gas
  • The molecules of ideal gas obey Newton's laws of motion thus they move in random motion
  • According to the above statements we can conclude that Helium gas can fill many more balloons as compared to fit the baloons inside the cylinder because the particles of gas is free to move in random motion and can occupy more volume

  A solution is made by dissolving 20 ml of acetic acid in 180ml of water. Calculate its volume concentration​
inn [45]

Answer:

water is 9/10

chemical would be 1/10

Explanation:

180/200 would be water concentration in solution

and 20/200 would be chemical solution concentration in solution (if the chemical were to be polar and mix)

Radon is: Select one: a. an alpha-emitting gas that penetrates the skin naturally. b. a naturally occurring gas produced during
inysia [295]

Answer:

A

Explanation:

Radon is an alpha emitter. It emits alpha particles giving off gamma ray. It is a radioactive byproduct of radium-222.

Radon also penetrates the skin. This is because radon is a gas and chemically unreactive with most materials, it moves easily through very small spaces, such as those between particles of soil and rock, to the soil surface

Option B is wrong. It is produced during radioactive decay of radium and not uranium.

Option C is wrong. Radon is not a metallic element.

Option D is wrong also. It is not produced from photochemical smog

Option E is wrong. This is an extension of option B. Uranium is generally used in nuclear plant operations and not radium

Characteristics of the water at the mountain source: Speed: Temperature Oxygen Level Nutrient Level
aksik [14]

Describe the characteristics of the water at the mountain source:

Answer:

The answer is below

Explanation:

Speed: there will be faster speed due to the steep slope movement of water from the mountain.

Temperature: there will be lower temperatures as a result of the faster speed of water movement which reduces the influence of solar radiation on it.

Oxygen: the oxygen content is higher due to little or no residue particles present in it.

Nutrient Level: this is considered somewhat low as a result of the water coldness and speed which does not support the nutrition base to form.
