Answer:
The symbol used to separate the product from each other or reactants from each other is 'plus' (+) .
Explanation:
In chemical equation the symbol used to separate the product from each other or reactants from each other is 'plus' (+) .
While the symbol used to separate the reactant and product from each other is '→'
For example:
Consider the following reaction.
2H₂ + O₂ → 2H₂O
Two moles of hydrogen react with one mole of oxygen to form two moles of water. The both reactant hydrogen and oxygen are separated by the + while reactant and products are separated by → .
Answer:
Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals (with different energies, shapes, etc., than the component atomic orbitals) suitable for the pairing of electrons to form chemical bonds in valence bond theory.
Answer:
240 seconds
Explanation:
Data Given:
Distance Radio travel to earth = 7.19 ×10⁷ km
Speed of this radio signal = 3.00 ×10⁸ m/s
Solution:
First convert Km to m
1 km = 1000 m
7.19 ×10⁷ km = 7.19 ×10⁷ x 1000 = 7.19 × 10¹⁰m
Formula used to calculate time
Speed (S) = distance (d) / time (t)
rearrange above equation for time
time (t) = distance (d) / Speed (S) . . . . . . . . .(1)
Put values in equation 1
time (t) = 7.19 × 10¹⁰/ 3.00 ×10⁸ m/s
time (t) = 240 s
So 240 seconds it take for the signal to reach the earth
