A transmission electron microscope would be the best microscope choice to study A. Structures smaller than cells. <span>Transmission electron microscopes are best used to study the internal organs of a cell.</span>
soap and water would be the best soak it in water for 20 miuntes then wash it
Solids are generally held together by ionic or strong covalent bonding, and the attractive forces between the atoms, ions, or molecules in solids are very strong. In fact, these forces are so strong that particles in a solid are held in fixed positions and have very little freedom of movement.
hope it helps...!!!
<span><span />It is water’s Ionization Property. Water
Ionization also known as self-ionization or auto ionization of water creates a
positive and Negative ion which is essential for chemical reactions. It is a
reaction of pure water in where a water molecule and H2O combined to make a
hydroxide ion. It usually occurs due to the electric field fluctuation between
2 neighbouring molecules. It is a property of pure water that mixed or
dissociates to from a new substance which is a hydrogen ion (positive ion) and
hydroxide ions (negative ion)</span>
Answer:
C8H17N
Explanation:
Number of moles of c
13.90 × 10^-3/44 g/mol × 1 = 0.000316 moles
Mass of C= 0.000316 moles × 12 = 0.00379 g
Number of moles of H
6.048 × 10^-3/18 × 2 = 0.000672 moles
Mass of H
0.000672 moles × 1 = 0.000672 g
Mass of N
0.005024 - [0.00379 g + 0.000672 g]
= 0.000562 g
Number of moles of N
0.000562 g/14 = 0.00004 moles
Divide through by the lowest ratio;
C= 0.000316/0.00004, H= 0.000672 /0.00004, N= 0.00004/0.00004
C= 8, H = 17, N = 1
Hence the empirical formula is;
C8H17N
