Answer:
3.6 × 10²⁴ atoms of O
Explanation:
Let's consider the molecular formula of silver nitrate: AgNO₃.
We can establish the following relations:
- 1 mol of AgNO₃ has 6.02 × 10²³ molecules of AgNO₃ (Avogadro's number).
- 1 molecule of AgNO₃ has 3 atoms of oxygen.
The atoms of oxygen in 2.0 moles of silver nitrate are:
Answer:
i. The height of its jump is approximately 0.115 m
ii. The time of flight of its jump is approximately 0.306 seconds
iii. The range of its jump is approximately 0.795 m
Explanation:
The angle at which the grasshopper jumps, θ = 30°
The speed with which the grasshopper takes off, u = 3 m/s
i. The height of its jump 'h', is given by the following relation;
Where;
g = The acceleration due to gravity ≈ 9.81 m/s²
Therefore;
The height of its jump, h ≈ 0.115 m
ii. The time of flight of its jump, 't', is given as follows;
Therefore;
The time of flight of its jump, t ≈ 0.306 seconds
iii. The range of the jump is given by the following projectile motion equation for the range as follows;
Therefore;
The range of the jump, R ≈ 0.795 m.
Answer: Metalloids
Explanation:
The dark “stair step” line on the right side of the periodic table is where the metalloids are. Metalloids “touch” the SSL. (Stair step line)
The metals are to the left of the SSL and the non metals are to the right of the SSL.
Since there are 22.4 L/mol at STP, you would convert 1000mL to 1 L then divide that by 22.4, meaning your answer would be 0.0446 rounded to 0.04
