B) Observations and experimentation
Explanation:
this is the most suitable words to describe how is Science used in describing the world. we collect the knowledge in organized way and provide it with explanations and start to predict about the future world
ِAny Inventions are based on Science and no Inventions without Observations and experimentation
No one of us have went to a chemistry or a physics labs without using Observations and experimentation
2NH₃(g) + CO₂(g) → CO(NH₂)₂(s) + H₂O(l)
is the balanced equation for the synthesis of urea.
Answer:
The coefficients are 2 for H₂O and 1 for Ca(OH)₂.
Explanation:
Let's consider the following reaction.
Ca(OH)₂(aq) + 2 HCl(aq) → CaCl₂(aq) + 2 H₂O(l)
According to the balanced equation, the molar ratio of H₂O to Ca(OH)₂ is 2:1. Using this conversion factor, we have the following proportion:
moles Ca(OH)₂. (2 mol H₂O ÷ 1 mol Ca(OH)₂) = moles H₂O
