Answer:
the process in which energy is emitted by one object, transmitted through space, and absorbed by another
Explanation:
Radiation is energy that comes from a source and travels through space and may be able to penetrate various materials. Light, radio, and microwaves are
types of radiation that are called nonionizing.
1.27moles of K3PO4 can be formed.
Answer: In a chemical equation the reactants are located on the left side and the products are located on the right side.
One aluminum atom will cost 0.84 × 10⁻²³ cents.
Explanation:
Aluminium costs 85 cents per 453.592 grams.
number of moles = mass / atomic weight
number of moles of aluminium = 453.592 / 27 = 16.8 moles
To calculate the number of aluminum atoms we use the Avogadro's number:
if 1 mole of aluminum contains 6.022 × 10²³ aluminum atoms
then 16.8 moles of aluminum contains X aluminum atoms
X = (16.8 × 6.022 × 10²³) / 1 = 101.17 × 10²³ aluminum atoms
Now, taking in account the aluminium price, we devise the following reasoning:
if 101.17 × 10²³ aluminum atoms costs 85 cents
then 1 aluminum atom costs Y cents
Y = (1 × 85) / (101.17 × 10²³) = 0.84 × 10⁻²³ cents
