Answer:
- 1.602 x 10⁻¹⁹coulombs
Explanation:
Charge on individual oil droplet would be multiple of charge on one electron . So we will find out the minimum common factor of given individual charges that is the LCM of all the charges given.
LCM of given charges like 3.204 , 4.806 ,8.01 and 14.42 . We have neglected the power of ten( 10⁻¹⁹) because it is already a common factor to all.
The LCM is 1.602 . So charge on electron is 1.602 x 10⁻¹⁹.
Answer:
0.375 grams are needed to make 25 mL solution.
Explanation:
Mass of 
cuprous nitrate required to make 1 l of solution = 15 g.
1 L = 1000 mL
Mass of cuprous nitrate required to make 1000 mL of solution = 15 g
Mass of cuprous nitrate required to make 1 mL of solution:
Mass of cuprous nitrate required to make 25 mL of solution:
0.375 grams are needed to make 25 mL solution.
It has an excess of electrons
the nuclei of its atoms are positively charged
it has a deficiency of electrons
the electrons of its atoms are positively charged
Answer:
4.62 atm
Explanation:
To find the missing pressure, you need to use the Combined Gas Law equation:
P₁V₁ / T₁ = P₂V₂ / T₂
In this equation, "P₁", "V₁", and "T₁" represent the initial pressure, volume, and temperature. "P₂", "V₂", and "T₂" represent the final pressure, volume, and temperature.
P₁ = 8.01 atm P₁ = ? atm
V₁ = 715 mL V₁ = 963 mL
T₁ = 67 °C T₁ = 52 °C
P₁V₁ / T₁ = P₂V₂ / T₂
(8.01 atm)(715 mL) / 67 °C = P₂(963 mL) / 52 °C
85.47985 = P₂(963 mL) / 52 °C
4444.952 = P₂(936 mL)
4.62 atm = P₂
