we will all die bc plants make oxygen and and if we dont have oxygen then we die
Explanation:
Answer:
Applied
Explanation:
Since Brent is using his existing scientific knowledge to create a new product or invention then this falls under the category of Applied Research. Applied research includes using any theoretical or proven information in order to create something physical that can be used in our real-life world. Usually, this research focuses on solving a problem through the use of technology. Thisis exactly what Brent is trying to do by creating a new plastic that does not have harmful chemicals that can hurt babies in the long term.
The graph shouldn't change because a catalyst isn't supposed to have any type of affect
It would be in the fourth shell.
The density of silver can be calculated by using the following formula:
Here, m is mass and V is volume.
To calculate density, mass of silver needs to be calculated first.
In FCC, the number of Ag atoms in a unit cell will be 4, atomic mass of Ag is 107.87 g/mol and number of atoms in 1 mol are 
atoms, thus, mass can be calculated as follows:
.
Now, volume can be calculated as follows:
First convert pm to cm:
Thus,
Putting the value to calculate volume,
Now, calculate density as follows:
Therefore, density of silver is 
.
