answer : 6CO2 + 6H2O → C6H12O8 + 5O2
Explanation:
Label Each Compound With a Variable
aCO2 + bH2O = cC6H12O8 + dO2
2. Create a System of Equations, One Per Element
C: 1a + 0b = 6c + 0d
O: 2a + 1b = 8c + 2d
H: 0a + 2b = 12c + 0d
3. Solve For All Variables
a = 6
b = 6
c = 1
d = 5
4. Substitute and Verify Result
6CO2 + 6H2O = C6H12O8 + 5O2
Answer:
- Initial: forward rate > reverse rate
- Equilibrium: forward rate = reverse rate
Explanation:
2NO₂(g) → N₂O₄(g) Kc=4.7
The definition of <em>equilibrium</em> is when the forward rate and the reverse rate are <em>equal</em>.
Because in the initial state there's only NO₂, there's no possibility for the reverse reaction (from N₂O₄ to NO₂). Thus the forward rate will be larger than the reverse rate.
Density= mass/volume
step one :
convert m3 to ml
1m^3 =1000000ml
0.250m^3 x1000000=250000ml
step two: convert mg to g
1mg=0.001g, therefore 4.25 x108mg=0.459g
density is therefore= 0.459g/250000=1.836 x10^-6g/ml
I think the sun would've seem bigger than the moon.
<u>Given:</u>
Initial amount of carbon, A₀ = 16 g
Decay model = 16exp(-0.000121t)
t = 90769076 years
<u>To determine:</u>
the amount of C-14 after 90769076 years
<u>Explanation:</u>
The radioactive decay model can be expressed as:
A = A₀exp(-kt)
where A = concentration of the radioactive species after time t
A₀ = initial concentration
k = decay constant
Based on the given data :
A = 16 * exp(-0.000121*90769076) = 16(0) = 0
Ans: Based on the decay model there will be no C-14 left after 90769076 years
