Answer:
They all end up in the oceon
Explanation:
Answer:
Explanation:
The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged). Atoms have different properties based on the arrangement and number of their basic particles.
Answer:
Explanation:
Since, the atomic mass of the elements is a characteristic property of the elements, you can use the data given, number of moles and mass in grams of the product, to calculate the atomic mass of the product, and then compare with the atomic masses of the elements (information foun in any periodic table).
<u>1) Atomic mass of the product</u>:
- Atomic mass = mass in grams / number of moles
- Atomic mass = 604.4 g / 6.3 mol = 95.94 g/mol ≈ 94.9 g/mol (rounded to three significant figures)
<u>2) Periodic table:</u>
- Molybdenum, Mo, the element with atomic number 42, has atomic mass equal to 95.94 g/mol.
<u>3) Conclusion</u>:
So, you can conclude safely that the element you have produced is Molybdenum.
Answer:
The answer to your question is V2 = 18.45 l
Explanation:
Data
Volume 1 = V1 = 12.3 l
Temperature 1 = T1 = 40°K
Volume 2 = V2 = ?
Temperature 2 = T2 = 60°K
Process
To solve this problem use Charles' law
V1/T1 = V2/T2
-Solve for V2
V2 = V1T2 / T1
-Substitution
V2 = (12.3 x 60) / 40
-Simplification
V2 = 738 / 40
-Result
V2 = 18.45 l
