Scientists define work as the spending of energy. True False

Chemistry
1 answer:
Hoochie [10]3 years ago
7 0
True; scientist define work as the spending of energy. This is because energy is required to move an object. For work to be done an object has to be moved from one point to another. Work is measured in joules similar to energy which is also measured in joules. Mathematically, work done is given by the product of force and distance moved by an object or a body.

Besides water, what is the product of a Neutalization Reaction between H2SO4 and LiOH?
tigry1 [53]

Answer:

The answer to your question is d. Li₂SO₄

Explanation:

Data

H₂SO₄ reacts with LiOH

Process

This is a neutralization reaction that occurs between an acid and a base and the products will always be water and a binary or ternary salt.

In this reaction, the acid is H₂SO₄ and the base is LiOH, then the products will be water and Lithium sulfate.

Balanced chemical reaction

                                 H₂SO₄  +  LiOH  ⇒   Li₂SO₄  +  H₂O

How the fossil evidence helped you put the landmasses together (what was your process)
Otrada [13]

Explanation:

The idea behind using fossils to correlate two land masses was first put into limelight by a British geologist, Williams Smith.

According to the principle of fossil and fauna succession "fossils and fauna succeed one another in a define order".

This implies organisms evolve in predictable manner.

Since we know that certain types of organisms live within a period in time on the earth surface, we expect that such organisms would be fossilized in the geologic record and preserved.

  • Identify the fossil record in one part of the land mass. Log the rock types with the corresponding fossils in them.
  • On the other side, repeat the same process.
  • Look for unconformity surfaces where some part of the stratigraphic records might have been lost.
  • If the fossil records on one side corresponds with that on the other other side, it suggests that the land masses must have once been joined together.
  • The logic is that when the organism were on the same land mass, they thrived and lived together.
  • They became fossilized together till the lands separated.
