Answer:
Patter 1: Ionization Energy Decreases going down a group
Pattern 2: Ions tend to gain/lose the least amount of electrons
Take oxygen, for example. Oxygen has 8 electrons. To become like a noble gas it could either gain two to become like neon or it could lose six to become like helium. So what will oxygen do—gain two or lose six? As a general rule, atoms will gain or lose the fewest number of electrons possible.
Explanation:
Answer:
N(Au) = 1,20 × 10²²
Explanation:
1) n(Au) = m ÷ M = 4.60 g ÷ 197 g/mol = 0,02 mol
2) N(Au) = n(Au) × N(a) = 0,02 × 6.02*10²³ = 1,20 × 10²²
Answer: Option (B) is the correct answer.
Explanation:
Equilibrium constant is defined as the relationship present between the amounts of products and reactants which are there at equilibrium in a reversible chemical reaction at a given temperature.
For example,
Mathematically,
As the value of equilibrium constant depends on rate constants of the forward and reverse reactions. And, this rate of reaction also changes with change in pressure and temperature.
Therefore, it will also lead to change in equilibrium constant but it does not depend on initial amount pf reactants.
Thus, we can conclude that in general, the value of the equilibrium constant for a chemical reaction does NOT depend on the initial amounts of reactants present.
Answer is 456 mmHg.
<em>Explanation;</em>
This is a simple unit conversion problem.
1 atm = 760 mmHg
Hence,
0.600 atm = (760 mmHg
/ 1 atm) x 0.600 atm
= 456 mmHg
Pressure can be measured by using many units such as atm, Pa, torr, bar, cmHg, mmHg and so on.
The relationships among those units as follows
1 atm = 101325 Pa = 1.01325 bar = 760 torr, 760 mmHg = 76 cmHg
