Answer:
Retrograde Motion
Explanation:
The theory that the earth revolves around the Sun is called the heliocentric theory, helio meaning 'sun' and centric meaning 'in the center.
' This theory was developed in parts by different astronomers over many years, namely Aristarchus, Copernicus, Kepler, and Galileo.
The reaction from society at the time was that the heliocentric theory was not even worth talking about.
Everyone had evidence to prove that the Earth was the center because if the sun started at one point in the morning and ended at another at night, it was common sense that we were obviously the center.
Copernicus heliocentric theory or it is also named as Sun-centred theory had accepted by Galileo.
The geocentric model is also known as geocentrism.
Answer:
Option 3 - Grignard reagents are strong bases and option 4 - Grignard reagents are strong nucleophiles
Explanation:
The carbon in grignard reagent has a very strong carbanionic character which gives grignard reaction it's unique characteristic of a strong base and strong nucleophile.

1.45 moles of P2O3 contains 1.45 moles of O3 which means 4.35 moles of O:
1.45 × 3 = 4.35 moles of O
Then you can calculate moles of O2 by dividing it by 2:
4.35 moles ÷ 2 = 2.175 moles of O2 needed

Plants are chlorophyll-containing photosynthetic organisms. Thus, they convert solar or radiant energy into chemical energy under the process termed as photosynthesis.
<u>Explanation:</u>
- Plants are chlorophyll-containing photosynthetic living beings. Consequently, they convert radiant energy into chemical energy under the procedure named photosynthesis.
- Except for remote ocean hydro-thermal environment, the sun is the only source for all biological systems on earth. Plants catch just 2-10 percent of the solar radiation and transmit it as chemical energy. All creatures are reliant for their nourishment on producers (plants), either directly or indirectly. So there is a stream of energy from the sun (radiant energy) to producers and then to consumers (chemical energy).
