Answer:
The temperture and about to flowers could affect the behavior of the bees
Explanation:
Answer:
2 1 H
Explanation:
We must remember that a nuclear equation is only said to be balanced when the mass and charges on both sides of the nuclear reaction equation correspond.
If we look at the nuclear equation; the total mass on the right hand side is 4 units while the total charge on the right hand side is two units.
This implies that the missing particle must be 2 1 H
1.4448e24 or 1.448x10^24. Don't forget to round to your significant figures if required by your teacher.
1)
Moles = mass / Mr
Mr of Fe = 56
Moles of Fe = 225.5 / 56
Moles of Fe = 4.03
Molar ratio CO : Fe = 3 : 2
Moles of CO = 4.03 x 3/2
Moles of CO = 6.04 moles
Mass of CO = 6.04 x (12 + 16)
Mass of CO = 169.1 grams
2)
Moles of Na = 65.4 / 23
Moles of Na = 2.84
Molar ratio Na : H₂ = 2 : 1
Moles of H₂ = 1.42
Each mole has 6.02 x 10²³ particles
Molecules of Hydrogen = 1.42 x 6.02 x 10²³
Molecules of Hydrogen = 8.55 x 10²³ particles
We can theoretically create as many elements as we want in laboratories.
All the naturally existing elements on earth have however been discovered.
