As we know,
1 mole of any substance contains 6.022 × 10²³ particles. And 1 mole of NO₂ (equal to 46 g) contains 6.022 × 10²³ Molecules. Hence,
6.022 × 10²³ Molecules of NO₂ = 46 g
So,
2.4 × 10²³ Molecules of NO₂ = X g
Solving for X,
X = (2.4 × 10²³ Molecules × 46 g) ÷ 6.022 × 10²³ Molecules
X = 18.33 g
Answer:
B
Explanation:
Applying law of electrostatic which states that like charges repel each other and unlike charges attract each other
N and S are unlike charges that turn and make the former repulsive force (due to two like charges N and N)to <em>reduce</em> and attractive force between N and S to <em>increa</em><em>se</em>
To convert from atoms of argon to moles of argon, you need to divide by Avogadro's constant.
3.01*10^23 atoms *(1 mole/6.022*10^23 atoms) = 0.500 moles Ar
0.500 moles of Argon is equal to 3.01*10^23 atoms of Argon.
Because seasons are caused by the changing angles that sunlight strikes the Earth (due to it's tilted axis), a decrease in tilt would mean less extreme seasons. Spring and fall are not affected by tilt because they are at the point in orbit where sunlight is hitting the earth evenly. However, less tilt would mean less of a change in angle around the orbit and therefore cooler summers and warmer winters.
