The answer is na3po4+3koh=3naoh+k3po4
<span>Answer:
2 C8H18 + 25 O2 => 16 CO2 + 18 H2O
1.0 kg = 1000 g C8H18 = 1000 g / 114.2293 g/mole = 8.75 moles C8H18
8.75 moles C8H18 produce (16/2) (8.75) = 70 moles CO2
70 moles CO2 = (70 moles) (44.0096 g/mole) = 3081 g CO2 = 3.1 kg CO2</span>
When we can get the Kinetic energy from this formula KE= 1/2 M V^2and we can get the potential energy from this formula PE = M g H
we can set that the kinetic energy at the bottom of the fall equals the potential energy at the top so, KE = PE
1/2 MV^2 = M g H
1/2 V^2 = g H
when V is the velocity, g is an acceleration of gravitational force (9.8 m^2/s) and H is the height of the fall (8 m).
∴ v^2 = 2 * 9.8 * 8 = 156.8
∴ v= √156.8 = 12.5 m/s
Radiation is a bad chemical it can cause death
H₂ = 2 g/mol
1 x 2 = 2 g of H₂
________________________
K = 39.09 g/mol
2 x 39.09 = 78.18 g of K
________________________________
Mg = 24.3 g/mol
3 x 24.3 = 72.9 g of Mg
_________________________________
He = 4 g/mol
4 x 4 = 16 g of He
___________________________________
Order : K , Mg , He and H₂
hope this helps!
