Answer:
Both ammonia and chlorine are soluble in water and hence, would dissolve in water if substance X is water and could not be collected. Ammonia gas would react with concentrated sulphuric acid to produce a salt and as ammonia is less dense than air, it should not be collected via a downwards delivery method.
Answer:
Answer is below.
Explanation:
Photosynthesis is a process that involves three main actors (or ingredients); sunlight, water, carbon dioxide.
Statistics has it that there was no sunlight all through the day.
- Let's check then if there was availability of water and the gas carbon dioxide.
There was rainfall all day
- This means that some photosynthetic activity would take place.
What about the gas that plants breathe in?
- There is always substantial amount of CO₂ in the atmosphere.
A SECOND WAY TO LOOK AT IT IS:
by checking the two stages of photosynthesis.
- In the first stage, sunlight is the main actor. Sunlight is trapped and stored as energy in the chloroplasts of green plants.
- In the second stage, CO₂ is the main actor. With CO₂, the chemical compound - from the first stage - ATP is used to produce sugar and organic compounds which are the food of/for green plants.
Answer: The correct option is (2).
Explanation:
Spring tides
When the Sun, the Moon and The Earth, all are arranged in straight line.Due to gravitational pull of Sun and Moon these tides are occurred.These tides occur twice in a lunar month regardless to any season.
Whereas Lunar tide is due to gravitational pull of Moon on the the sea of the earth planet.
Low tide: These are the tides formed in the sea when the sea is at the lowest level.
Neap tides occur when the Sun and the Moon form right angles with the Earth
So, the given figure represent Spring tide.
