What does it mean when to say that mass is coserved during a physical change?

SAT
1 answer:
Likurg_2 [28]3 years ago
4 0

During a physical change, the mass is conserved because it isn't permanently changed, like a chemical change. A chemical change would be something like burning a piece of paper, and a physical change would be something like cutting up pieces of paper (can be put back together).

Sav [38]

The classification of each of the elements into nonessential element, essential bulk element, or essential trace element are as follows:

Nonessential elements:

  • Alumimium,
  • Argon,
  • Helium

Essential bulk elements:

  • Carbon,
  • Nitrogen,
  • Calcium,
  • Hydrogen

Essential trace elements:

  • Iron,
  • Copper.

The complete question

The elements are: Hydrogen, iron, Copper, Nitrogen, Helium, Carbon, Aluminum, Calcium, Argon

<h3>What is Essential and Nonessential Elements?</h3>

Nonessential elements as the name implies are elements which are not necessary for the functional routine of the body and hence are not included in diets.

Essential bulk elements are elements which are needed for the proper functioning of the body and hence are required in relatively large amounts.

Essential trace elements are required in minute quantities in the body.

Which one of the following chemical equations does not correspond to a standard molar enthalpy of formation?.
o-na [289]

There are different kinds of theory. The chemical equation that does not correspond to a standard molar enthalpy of formation is c. N₂(g) + O₂(g) ⇒ 2 NO(g).

<h3>What is standard enthalpy of formation ?</h3>

The standard enthalpy of formation of any element  is known to often occur in the standard state that is zero  of that element.

For example, even though oxygen can be found as ozone (O3), O2 is the known to be the most stable form.

What can you say about the series an in each of the following cases?
Likurg_2 [28]

The exercise is related to the Ratio Test for Convergence. The rules for this kind of test are given below.

<h3>What are the rules for Ratio Test for Convergence?</h3>

The rules are:

  • If the limit is less than 1 when conducting the ratio test, your series is definitely convergent.
  • The test is inconclusive if the limit is equal to 1.
  • The series is divergent if the limit is greater than 1.

Using this knowledge, we are able to state that

  • A is not conclusive.
  • C's convergence is absolute.
  • There is divergence with D and E.
  • B and F appear to be employing the nth-term test. The nth-term involves determining the sequence's limit as it approaches infinity.

The nth-term test determines whether a series is divergent if the limit is bigger than 0, thus, both B and F are divergent series.

Please see the attached for the full question and the link below for more about Ratio Test for Convergence:
