Answer:

In general, a scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of a phenomenon is called a scientific theory. It is a misconception that theories turn into laws with enough research.

Answer:

A scientific law is a description of an observed phenomenon.this is not an explanation of a phenomenon but a description.

Hypothesis becomes a law when  they follow a line of reasoning and formulate a theory.then once a theory has been evaluated through a series of testing it becomes a law.

Hope this helps and if it does pls mark as brainliest answer

What is the mass of an aluminum cylinder with 0.234 in diameter and a length of 2.697
Lemur [1.5K]

0.33g

Explanation:

Given parameters:

Diameter of cylinder = 0.234cm

length = 2.697cm

unknown:

mass of the cylinder = ?

Solution:

To solve this problem, we know that density of the aluminium can be determined and it is a constant.

 Density is the mass per unit volume of a substance

 Density = \frac{mass}{volume}

 Mass of the cylinder = density x volume

To calculate the volume of cylinder;

  Volume = π r² h

     radius of the cylinder = \frac{0.234}{2} = 0.12cm

Volume = 3.142 x 0.12² x 2.697 = 0.12cm³

Density of aluminium = 2.7g/cm³

 Mass of the cylinder = 0.12 x 2.7 = 0.33g

Draw the structure corresponding to the common name α−chloro−β−methylbutyric acid
uysha [10]

Structure of a-chloro-b-methylbutyric acid (2-chloro-3-methylbutyric acid is attached below.


The structure was drawn using following information.


1) First, the parent chain was identified. The parent chain is containing four carbon atoms, also, this chain belongs to carboxylic acid as the compound name ends with Butyric acid i.e. butyr (Butane) -ic acid (carboxylic acid).


2) Secondly, the positions of substituents were assigned by using the rule which sates that the numbering in carboxylic acid must satrt from the carbonyl carbon. Therefore, the carbon which is attached to carbonyl carbon is named as alpha (2nd position) and carbon next to alpha carbon is named as beta carbon (3rd position). Hence, we add chlorine atom on 2nd carbon next to carbonyl group and methyl group at 3rd carbon with respect to carbonyl carbon.

The increase in atomic radius as you go down the periodic table is caused by?​
Kryger [21]

Answer: The number of energy levels increases as you move down a group as the number of electrons increases. Each subsequent energy level is further from the nucleus than the last. Therefore, the atomic radius increases as the group and energy levels increase.

If the density of a metal bar is 3.47 g/mL and volume is 30 mL, calculate the mass of the metal bar in grams (g). Show the steps
Hitman42 [59]

Answer:

m=104.1g

Explanation:

Hello,

In this case, considering that the density is considered as the quotient of the mass and volume:

\rho =\frac{m}{V}

We can easily compute the mass by solving for it as follows:

m=V*\rho =30 mL*3.47g/mL\\\\m=104.1g

Best regards.
