Answer:
= 29.64 g NaNO3
Explanation:
Molarity is given by the formula;
Molarity = Moles/Volume in liters
Therefore;
Number of moles = Molarity × Volume in liters
= 1.55 M × 0.225 L
= 0.34875 moles NaNO3
Thus; 0.34875 moles of NaNO3 is needed equivalent to;
= 0.34875 moles × 84.99 g/mol
= 29.64 g
Answer:
The Rutherford Model shows an atom with electrons orbiting a fixed, positively charged nucleus in set, predictable paths. The Bohr model shows electrons travel in defined circular orbits around the nucleus.
Answer is: Reactants and products are written in words; reactants are on the left, products are on the right side of reaction.
For example, balanced chemical reaction for cellular respiration (convert biochemical energy):
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O or:
glucose + oxygen → carbon dioxide + water.
Glucose and oxygen are reactants and carbon dioxide and water are products of reaction.
This reaction is exothermic (energy is released).
Word equation is a chemical reaction expressed in words rather than chemical formulas.

Radiation has optimized a number of process in the plastics industry. Infrared emitters are the devices that uses radiation which are used in the said industry. These are devices which could be adjusted precisely depending on the product and the process. These emitters can make plastics welding within seconds. And since they can be adjusted precisely, it saves a lot of time, space and of course energy.
