Answer:
<u><em>100N</em></u>
Explanation:
<u>Given</u> <u>Required</u>
Effort force = 50N Force applied to a resistance = ??
Ideal Mechanical Advantage (IMA) = 2
<u>Solution</u>
Force applied to a resistance = Effort force x Ideal Mechanical Advantage (IMA)
= 50N x 2
= 100N
Solution;
The gas is at STP;
Where; T = 273 K , P = 1 atm
We know that 1 mole of a gas at STP occupies a volume of 22.4 liters .
V1/n1 = V2/n2
n2 = (V2/V1) n1
n2 = (2 l/22.4 l)(1 mole)
n2 = 0.0893 moles
But 1 mole of a compound has 6.022 × 10^23 molecules
Thus, number of molecules = 0.0893 moles × 6.022 ×10^23 molecules
= 5.378 × 10^22 molecules.
Gold isn't very reactive (it's low on the reactivity table).
It doesn't react with oxygen or halogens with any ease, nor does it tend to dissolve in acid.
