A scientist does one trial for an experiment on positively and negatively charged objects, and there is an error in the results.

What should the scientist do instead?(2 points) He should choose different objects and conduct another experiment. He should complete more than one trial for more accurate results. He should complete a conclusion that gives an explanation of the result. He should complete research to gather more evidence and support.\

A phase is a part of a system with what type of composition?
TiliK225 [7]

Answer:

<u>uniform composition.</u>

Explanation:

A phase is a part of a system with uniform composition.

  • In physics and chemistry , a phase in a physically distinctive form of matter , such as solid , liquid , gas or plasma.
  • A phase matter is characterised by having relatively uniform chemical and physical properities . Phases are different from states of matter.
  • The states of matter (e.g ., solid , liquid , gas ) are phases but matter can exist in different phases and yet be in the same type of matter. For example , liquid mixtures can exist in multiple phases such as oily and aqueous phase.
  • some different types of phases are : solid, liquid,gas , plasma etc.
  • The term phase can also sometime mean describe equilibrium in phase diagram

What is the density of the marble when the mass = 10g
Marysya12 [62]
The density of marble is between 2.6 and 2.8 grams per cm³ .

Density doesn't depend on how much mass or volume of it you have.
The density of a chip of it is the same as the density of a truckload of it.

In an organic structure, you can classify each of the carbons as follows: Primary carbon (1o) = carbon bonded to just 1 other ca
Alla [95]

The question is incomplete, complete question is :

In an organic structure, you can classify each of the carbons as follows: Primary carbon (1°) = carbon bonded to just 1 other carbon group Secondary carbon (2°) = carbon bonded to 2 other carbon groups Tertiary carbon (3°) = carbon bonded to 3 other carbon groups Quaternary carbon (4°) = carbon bonded to 4 other carbon groups How many carbons of each classification are in the structure below? How many total carbons are in the structure? How many primary carbons are in the structure? How many secondary carbons are in the structure? How many tertiary carbons are in the structure? How many quaternary carbons are in the structure?

Structure is given in an image?

Answer:

There are 10 carbon atoms in the given structures out of which 6 are 1° , 1 is 2° , 2 are 3° and 1 is 4°.

Explanation:

Total numbers of carbon = 10

Number of primary carbons that is carbon joined to just single carbon atom = 6

Number of secondary carbons that is carbon joined to two carbon atoms = 1

Number of tertiary carbons that is carbon joined to three carbon atoms = 2

Number of quartenary carbons that is carbon joined to four carbon atoms = 1

So, there are 10 carbon atoms in the given structures out of which 6 are 1° , 1 is 2° , 2 are 3° and 1 is 4°.

Using what you know about the periodic table, choose all of the correct answers.
a_sh-v [17]

Answer:

Explanation:

Which of the following elements would lose an electron easily?

In particular, cesium (Cs) can give up its valence electron more easily than can lithium (Li). In fact, for the alkali metals (the elements in Group 1), the ease of giving up an electron varies as follows: Cs > Rb > K > Na > Li with Cs the most likely, and Li the least likely, to lose an electron
