Answer:
What is the best definition of "vehicle of contamination"?
-A preventive vaccine
-Any source of biological -contamination
An ambulance
-A food truck
Answer:
48 000 cm^2
Explanation:
8000 1cm cubes
each 1 cm cube side is 1 cm^2 and there are six sides to the cube , so each cube has 6 cm^2 surface area
and there are 8000 of them 8000 * 6 cm^2 = 48 000 cm^2
Answer:
The answer to your question is 203.8 g
Explanation:
Data
Average atomic mass = ?
Centium-200
Centium-203
Centium-209
Equal amounts
Process
1.- Determine the abundance of each isotope.
If they are in equal amounts in nature, just divide 100 by 3
100/3 = 33.33 % or 0.333
2.- Determine the Average atomic mass
Average atomic mass = Atomic mass 1 x abundance + Atomic mass 2 x
abundance + Atomic mass 3 x abundance
- Substitution
Average atomic mass = 200 x 0.333 + 203 x 0.333 + 209 x 0.333
- Simplification
Average atomic mass = 66.6 + 67.6 + 69.6
Result
Average atomic mass = 203.8 g
Answer:
Explanation:
Here, we want to write the chemical reaction
step 1:
we start by writing the reaction between iron and oxygen
We have this as:
step 2:
Now, we want to predict the product as follows:
step 3:
We proceed to balance the chemical reaction as follows by ensuring that the number of elements moles on the reactant side is equal to the number of moles of the elements on the products side as follows:
Answer:
C,
to make it simple 10 to the power of 3 is 1000, and 1000 multiplied by 3.753 is equal to 3,753.
