Answer:
Cell Differentiation and Tissue.
Explanation:
tissues are organized communities of cells that work together to carry out a specific function.
the molecular formula is calculated as follows
find the mole of each molecule
that is for carbon = 26.7/12= 2.23 moles
hydrogen= 2.24/1=2.24 moles
oxygen= 71.1/16=4.44 moles
find the mole ratio of each element
that is divide all moles by the smallest mole( 2.23)
for carbon=2.23/2.23=1,
hydrogen = 2.24/2,23=1
oxygen= 4.44/2.23= 2
the empirical formula = CHO2
therefore the molecular formula=(CHO2)n=270.1
{ ( 12x 1) + 1x1) +(16x2)}n=270.1
45n=270.1
n=6
molecular formula is therefore=(CHO2)6=C6H6O12
Answer:
Nuclear transmutation
Explanation:
The process in which an element spontaneously transforms into another isotope of the same element, or into a different element is called nuclear transumutation. It occurs when the number of protons or neutrons in the nucleus of an atom is changed.
<u>Answer:</u> 1.2 moles of carbon dioxide is produced for the given value of oxygen.
<u>Explanation:</u>
The chemical reaction for the combustion of acetylene follows the equation:
By stoichiometry of the reaction:
5 moles of oxygen produces 4 moles of carbon dioxide.
So, 1.5 moles of oxygen will produce = 
of carbon dioxide.
Hence, 1.2 moles of carbon dioxide is produced for the given value of oxygen.
