the first organisms to convert solar energy into chemical energy were most likely
Answers
First organisms to convert solar energy to chemical energy were the organisms which are called as cyanobacteria.
What is chemical energy?
Energy which is stored in the chemical bonds of chemical compounds is called chemical energy.Chemical energy is released during the occurrence of chemical reaction.Reactions wherein energy is given out in the form of heat is called exothermic reactions.
Chemical energy can be converted to other forms of energy like electrical energy during the process of electrolysis and to thermal energy as in the case of thermal engines.
It can also be converted to kinetic energy during explosions . It is stored in batteries, coal, biomass, food, vehicle air bags,etc.During digestion chemical energy is converted to mechanical and thermal energy.

rutherford and JJ thompson both contributed to what we know about the structure of the atom. What experiments did they perform and how did it change what we know about the structure of the atom? Furthermore describe the structure of an atom using only two words
Answers
Answer:
J.J. Thomson's experiments with cathode-ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. I would describe the structure of an atom as the plum pudding model.

Hello! My name is Galaxy and I will be helping you today. I hope you are having a nice day.
There are 3 main ways to measure temperatures, you have Celsius, Fahrenheit, and Kelvins.
Celsius and Fahrenheit are main ways to measure heat in non-scientific terms, althought they are used sometimes when needed.
Kelvins are used for Science as they are precise and can deal with temperatures that are super hot or super cold.
The lowest temperature in Kelvins is 0 degrees Kelvin, also known as Absolute Zero. There are no temperatures above that. So the answer to your question would be Kelvins.

Answer:
Plant cells and animal cells are both eukaryotic cells. They both have a nucleus, Golgi complex, endoplasmic reticulum, ribosomes, mitochondria, cytoskeleton and cell membrane. Only plants cells have a vacuole, cell wall and chloroplast, while animal cells have cilia, centrioles and lysosomes which plant cells don't usually have. Because of their cell walls plant cells are in rigid rectangular shapes while animal cells have looser round shapes. The main difference in their functions is that animals don't produce their own food while plan cells do.

Are crystals of different soluble solids similar?
Answers
Crystals of different soluble solids are not similar because they are amorphous and therefore do not have definite crystals.
What are crystal solids?A crystalline solid is a homogeneous solid in which the constituent particles, atoms, ions or molecules are arranged in a definite repeating pattern.
Most of the solid substances are crystalline in nature. The arrangement of particles in a crystalline solid is such that the total intermolecular force of attraction is at maximum.
Factors in which solubility depends are temperature, pH, and ionic strength.
Crystals of different soluble solids are not similar as they do not have definite crystals.

A car travels 76 km/hr for 11 hours. How far did the car travel in this time period (in kilometers)?
Answers
Answer:
836 km
Explanation:
76*11=836
Answer:
836km
Explanation:
76km/hr = 76×1000÷3600= 190/9 m/s
11hours =39600 s
Distance=speed×time
Distance=190/9 × 39600= 836,000m
So distance is 836,000m or 836 km.

What is the empirical formula of a molecule containing 65.5% carbon, 5.5% hydrogen, and 29.0% oxygen
Answers
number of moles= mass/molar mass(Mr)
=65.5/12
=5.5 moles
Hydrogen(H):
number of moles=mass/molar mass (Mr)
=5.5/1
=5.5 moles
Oxygen (O):
number of moles = mass/molar mass (Mr)
=29.0/16
=1.8 moles
EF= lowest number of moles over each of the elements
So,
C= 5.5/1.8 = 3
H= 5.5/1.8 = 3
O= 1.8/1.8 = 1
Therefore Emperical formula= C3H3O
