Explanation:
Weight is 120 pounds and mass is 54 kg
The mass of an object is same everywhere. If we were on the moon, its mass will remain to be 54 kg.
Weight of an object is given by :
g is acceleration due to gravity on that surface
For moon, it is 1/6 the gravitational force on Earth, g = 1.63 m/s²
1 pound = 4.45 N
It means my weight is 533.78 N
On the surface of Moon is will be :
Answer:
The answer to your question is: # of atoms = 2.42 x 10¹⁰
Explanation:
Data
radius = 248 pm
row = 6 cm long
Conversion
1 pm ------------------- 1 x 10 ⁻¹⁰ cm
248 pm -------------------- x
x = (248 x 1 x 10⁻¹⁰) / 1
x = 2.48 x 10⁻¹⁰ cm
Divide
# of atoms = 6 / 2.48 x 10⁻¹⁰
# of atoms = 2.42 x 10¹⁰
Answer:
Visible Light
Explanation:
It helps us see things around us!
Answer:
White or gray, odorless lumps or granular powder.
The ions present in the solution of Na₃PO₄ are:
3Na⁺¹ and 1PO₄⁻³
there are 3 sodium ions (Na⁺¹) are present, these are cations (+).
And 1 phosphate ion (PO₄⁻³) is present, this is anion (-),
When these cations and ions meet together a compound is formed, in this case 3 sodium ions make a bond with 3 oxygens of phosphate and makes a compound of sodium phosphate.
