Density is mass over volume. The density of iron is given in g/cm³
we have to first convert g/cm³ to kg/dL.
1000 g = 1 kg and 100 cm³ = 1 dL
the mass of 1 cm³ = 1 g
the mass of 100 cm³ / 1 dL = 100 g
then mass of 1 dL in kg is = 100 g / 1000 g/kg = 0.1 kg
volume of 0.1 kg is 1 dL
therefore density of iron is 7.86 g/cm³ x 0.1 kg/dL / g/cm³ = 0.786 kg/dL
volume of iron having mass 0.786 kg is 1 dL
then volume of iron having a mass of 4.62 kg is - 1 dL / 0.786 kg x 4.62 kg = dL
volume of iron is 5.88 dL
Answer:
D) constructive
Explanation:
Deposition is a constructive force since it involves dumping sediment in a particular location.
Answer: Chlorophyll is a green photosynthetic pigment found in plants, algae, and cyanobacteria.
Chlorophyll absorbs mostly in the blue and to a lesser extent red portions of the electromagnetic spectrum, hence its intense green color.
Green substance in producers that traps light energy from the sun, which is then used to combine carbon dioxide and water into sugars in the process of photosynthesis Chlorophyll is vital for photosynthesis, which helps plants get energy from light.
Chlorophyll molecules are specifically arranged in and around pigment protein complexes called photosystems, which are embedded in the thylakoid membranes of chloroplasts.

Answer:
236.02 grams of Na is produced by 600g of NaCl.
Explanation:
NaCl --> Na+Cl-
to find the number of moles NaCl has, divide the grams over the molar mass which is 600/58.44
number of moles of nacl= 10.2 moles
then turn moles back to grams which is moles x molar mass
10.2 moles x 22.9 mass
= 236.02 grams
