Answer:(16)(2000)m/s=32000m/s
Explanation: A diatomic oxygen has a molar mass of 16
Answer:
Mass % of hydrogen = 20.9 %
Explanation:
Given data:
Mass of hydrogen = 0.485 g
Mass of water = 2.32 g
Mass percent of hydrogen = ?
Solution:
Mass % of hydrogen = mass of hydrogen / mass of water × 100
Mass % of hydrogen = 0.485 g/ 2.32 g × 100
Mass % of hydrogen = 0.209 × 100
Mass % of hydrogen = 20.9 %
Yes because obviously some other organism lives off eating that organism so if they die off the other organisms will be affected heavily
Answer:
