After 17190 years, Carbon-14 will reach a mass of 15 grams.
Pi is your initial amount (120 grams)
0.5 as your exponential base represents your HALF life hence 0.5
t represents the time elapsed
c represents your given half life value of (5730)
P(t) represents the exponential function of your half life
120/2 =60
60/2 = 30
30 /2 = 15
As you can see above, 3 half lives of 5730 years EACH degraded the carbon-14 to 15 grams. You divide each number by two as it is a HALF life.
P(t)= Pi (0.5) ^t/c
P(17190) = 120 (0.5) ^17190/5730
P(17190) = 120 (0.5) ^3
P(17190) = 15 grams
So your answers should be 3 half lives or after 17190 years have elapsed!
Answer:
RbH(s)+ H2O(l) → RbOH + H2
Explanation:
The reaction is;
RbH(s)+ H2O(l) → Product
From Ahmad's statement, we know that the product of he reaction is going to be an Hydroxide (-OH) and hydrogen gas (H2)
So we have;
RbH(s)+ H2O(l) → RbOH + H2
0.276 kg
Explanation:
the reason for this is because according to abraham james when one butthole is in the other gives you a big huge belly causing you to review another butthole
Answer:
114.4 grams of P₄O₁₀
Explanation:
P₄ + 5O₂ → P₄O₁₀
50 grams of P₄ are (50 g / 123.88 g/m) = 0.403 moles
Ratio is 1:1 so 0.403 moles of phosphorus can produce the same amount of P₄O₁₀.
Molar mass P₄O₁₀ = 283.88 g/m
0.403 moles . 283.88 g/m = 114.4 g
Answer:
COARSE ADJUSTMENT KNOB — A rapid control which allows for quick focusing by moving the objective lens or stage up and down. ... FINE ADJUSTMENT KNOB — A slow but precise control used to fine focus the image when viewing at the higher magnifications. 6.
Coarse adjustment, using the coarse adjustment knobs, raises and lowers the stage more rapidly. Fine adjustment knobs are the smaller knobs and are also used to raise and lower the stage but more slowly and in a more controlled manner under higher magnifications.
