It describes how, when particles/mc/elements react, despite forming different substances the mass is neither created nor destroyed but only converted.
Travka [436]3 years ago

Answer:

It is a statement based on repeated experiments and observations, that assures its veracity.

Explanation:

Hello,

In this case, a raft of experiments and observations were previously carried out and analyzed in order to substantiate whether the mass remains constant when a chemical reaction is undergone into an isolated system. This, in addition to the given conclusion, led to a scientific law as the law of conservation of mass is considered as a statement that came up from repeated experiments and observations in which a repeatable behavior of matter assured its veracity over a wide range of similar conditions.

Best regards.

Which molecule has the greatest difference in electronegativity (DE) between the two different elements? A. CO_2 B. H_2S C. NH_3
Natalka [10]

Answer:

Water has the greatest ΔEN

ΔEN H₂O → 3.4 - 2.1 = 1.3   Option D.

Explanation:

We should find the Electronegativity data in the Periodic table for all the elements:

C : 2.6

O: 3.4

H: 2.1

S: 2.6

N: 3.0

a. ΔEN CO₂ → 3.4 - 2.6 = 0.4

b. ΔEN H₂S → 2.6 - 2.1 = 0.5

c. ΔEN NH₃ → 3 - 2.1= 0.9

d. ΔEN H₂O → 3.4 - 2.1 = 1.3

David is making lemonade he asked you could you some lemon juice and water the sugar starts to dissolve what can we do to speed
suter [353]

We could (a) stir faster and (b) warm the mixture.

<em>Stirring faster</em> moves freshly-dissolved sugar away from the solid and allows new water molecules to contact with the surface,

<em>Warming the mixture</em> gives the water molecules more kinetic energy, so their collisions with the surface of the sugar will be more effective in removing the sugar molecules.

List and discuss at least 4 reasons why a laboratory should operate using GLP.
Drupady [299]

Answer:

The list and discussions are stated below:

Explanation:

Good Laboratory Practice (GLP) is extremely important.

1. Organization

With GLP we can guarantee an organized work environment, which is essencial in a laboratory.

2. Safety

GLP promotes laboratory safety for personell, avoiding unecessary risks and preventing accidents.

3. Quality control

GLP ensures that experiments made and products developed in a laboratory have the demanded quality.

4. Reliability of results

GLP promotes quality of results reporting, wich directly influences the reliability of results.
