It was the English chemist, John Dalton, who put the pieces of the puzzle together and developed an atomic theory in 1803. Dalton 's atomic theory<span> contains five basic assumptions:
- All matter consists of tiny particles called </span>atoms<span>.
</span>- Atoms are indestructible and unchangeable.- Elements are characterized by the weight of their atoms.
- In chemical reactions, atoms combine in small, whole-number ratios.
- When elements react, their atoms may combine in more than one whole-number ratio.
Hope this helped!
Answer:
Volume of flask = 29.134 cm³
Explanation:
Mass of water = mass of filled stoppered flask - mass of empty stoppered flask.
Mass of water = 65.858 - 36.724 = 29.134 g
Density of water = 1 g/cm³
Volume = mass/ density
Volumeof water = 29.134 g/ 1g/cm³ = 29.134cm³
Therefore, volume of flask = 29.134 cm³
Most of the organic compunds burn to give CO2 and H2O
2C2H2 + 5O2 = 4CO2+ 2H2O

Answer:
<em>Neutron (¹₀n)</em>
Explanation:
<em>Nuclear Fission: </em>This is a process in which two or more light nuclei fuse or combine to form a heavier nucleus with a release of energy and radiation.
<em>Neutron: </em><em>A neutron is located in the nucleus of an atom, It has a neutral charge, The mass of neutron is 1.660540 x 10⁻²⁷ kg</em>
Therefore The type of radiation emitted during a nuclear process in which a nucleus with greater atomic number is formed is <em>Neutron (¹₀n)</em>
Answer:
1.006 * 103
Explanation:
Add the number between 1 and 9 and add a decimal accordingly . so the answer is 1.006 multiplied by 10 raised to power 3
