It’s called an ion . An atom that loses electron is called an ion
Answer : A.By
Step by Step Explanation
From the coefficients of the equation, we know that for every 3 moles of water consumed, 1 mole of diphosphorus trioxide is consumed.
This means we need to find the mass of 0.75 moles of diphosphorus trioxide.
- The atomic mass of phosphorous is 30.973761998 g/mol.
- The atomic mass of oxygen is 15.9994 g/mol.
So, the formula mass of diphosphorus trioxide is:
- 2(30.973761998)+3(15.9994)=109.945723996 g/mol.
Thus, 0.75 moles have a mass of:
- 0.75(109.945723996), which is about 82.5 g (to 3 sf)
The answer is 80 m.
Centripetal force (F) is a force that makes body move around a circular curve. The unit of force is N (N = kg * m/s²).
It can be represented as:

where:
m - mass
v - velocity
r - radius of the curve
We have:
m = 1,200 kg
V = 20 m/s
F = 6,000 N = 6,000 kg * m/s²
We need radius of the curve:
r = ?
So, if <span>

, then:
</span>

Number of protons is 11
Number of neutrons is 12
Number of electrons is 10
For a neutral Na, Sodium atom:
The mass number P+N = 23
Atomic number (E or P) = 11
A charged Na atom that has lost an electron is positively charged and so: Number of Protons = 11 (Still the same)
Number of neutrons = 12
Number of electrons = 11-1=10 (the atom has lost an electron)
If an atom loses electron, it becomes positively charged ie. P>E
