molar mass Mg = 24 g/mol ; MgF2 = 62 g/mol
<span>Mg + 2 NaF = MgF2 + 2 Na
</span>
24 g Mg ------------ 62 g MgF2
5.50 g Mg ---------- ( mass MgF2)
mass MgF2 = 5.50 x 62 / 24
mass mgF2 = 341 / 24
= 14.208 g of MgF2
hoope this helps!
Answer:
→
Explanation:
→
On the left you have:
Na: 1
Br: 2
On the right you have:
Na: 1
Br: 1
To get the Br to be the same on both sides, you would multiple the NaBr by 2. Then, you will have 2 Na so you put a coefficient of 2 in front of the Na aswell.
Answer:
666.67 kg is the mass of a car.
Explanation:
Momentum is defined as amount of motion possessed by the the moving body. It is mathematically calculated by multiplying mass into velocity by which object is moving.
Mass of the car = m =?
Velocity of the car = v = 15.0 m/s
Momentum of the car = P = 10,000.00 kgm/s
666.67 kg is the mass of a car.
To answer this, we look at the polarities of these molecules given. A molecule is said to be polar when there is an unequal shraing of electrons the opposite is called nonpolar.
CH4 = nonpolar
CH3OH = polar
CH3 CH3 = nonpolar
CH3 CH2 CH2 OH = polar
<span>CH3 CH2 CH2 CH2 CH2 CH3 = nonpolar</span>
