Number of particles : 8.603 x 10²³
Further explanationStandard conditions for temperature and pressure are used as a reference in certain calculations or conditions
Assumption⇒ Standard Conditions
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters/mol.
1 mol = 6.02 x 10²³ particles (atoms, ions, or molecules)
32.0 liters of Helium
[tex]\tt mol=32:22.4=1.429[/tex]
Number of particles :
[tex]\tt 1.429\times 6.02\times 10^{23}\\\\=8.603\times 10^{23}[/tex]
A 5 kg block
is pulled across a table by a horizontal force of 4O N with a frictional force ot 8N pOsing the motion. Calculate the acceleration of the oject. 12 An ahia iddt
Answer:
By Newton's 2nd law, m*a=sum_of_forces where m is the mass and a the acceleration. Here there are two forces in opposed directions.
Thus 5*a=40-8=32 therefore a=32/5=6.4m^s/2
Convert each measurement into scientific notation. For example, 8.73 Ms is the same as 8.73 x 106 because the “M” stands for 106
107pg
(I'm assuming I have to convert the 107pg but I am unsure of how to answer this)
Answer:
[tex]107pg = 107 \times {10}^{ - 12}g =1.07 \times {10}^{ - 10} g\\ because \: pico, \: p = {10}^{ - 12} .[/tex]

A dark blue beaker labeled 100 millimeters Y has an arrow leading to a pale blue beaker labeled 99 millimeters H subscript 2 O. This has an arrow leading to a white beaker labeled 99 millimeters H subscript 2 O. Each arrow has a label 1 milliliter over it. The dark blue beaker has a box below it labeled Beaker number 1. The pale blue beaker has a box below it labeled Beaker number 2. The white beaker has a box below it labeled beaker number 3.
Does taking 1 mL of solution Y (pure bleach) out of the first beaker change the solution’s concentration?
What would the concentration of the second beaker be?
If Beaker #2 is a 1% solution of Y, and Beaker #3 is 1/100th of that in the final solution, what percentage solution would Beaker #3 be?

Create a sort of infomercial featuring a solution you created or designed.
Say a few statements about it.
please help
Answer:
Informercials, like the class Shamwow Informercial are an example of how structure and technique can have a huge effect on how a user or prospect is driven towards taking a specific action like clicking a buy button.
Informercials follow a specific structure that any small business can use to drive action but few businesses ever consider using it when they pitch their product or service. In this post, we'll describe the structure and give you examples of how you can use it in your business.
The question above wants to test your ability to create an infomercial using your creativity. For that reason, I can't create an infomercial for you, but I'll show you how to create one.
First, you need to know that an infomercial is an advertisement made to be played on television, usually associated with sales, but can be used to present information.
Based on this, you should create your newsletter as follows:
Establish the element that your infomercial wants to present.Show what are the issues related to this element.Show the solutions you want to present to these problems.Show how these solutions are truthful and reliable.In the image below, you can see a tutorial on how to make an infomercial.
