Convert the given masses to moles.
• (55.0 g Na) (1/22.989 mol/g) ≈ 2.39 mol Na
• (67.2 g Cl₂) (1/70.9 mol/g) ≈ 0.948 mol Cl₂
The reaction consumes a ratio of 2 mol Na to 1 mol Cl₂, which means 0.948 mol Cl₂ reacts with 2 × 0.948 ≈ 1.90 mol Na, leaving an excess of about 0.494 mol Na.
The amount of NaCl produced is the same as the amount of Na consumed, so we end up with about 1.90 mol NaCl, which has a mass of about
(1.90 mol NaCl) (58.44 g/mol) ≈ 111 g NaCl
That sounds like a rectangular pyramid to me
The net of a rectangular pyramid consists of one rectangle and four triangles. The rectangle is the base of the pyramid, and the triangles are the lateral faces.
Answer:
endometrium

Answer:
Stroma, in botany, refers to the colorless fluid surrounding the grana within the chloroplast. Within the stroma are grana (stacks of thylakoid), and the sub-organelles or daughter cells, where photosynthesis is commenced before the chemical changes are completed in the stroma. Photosynthesis occurs in two stages.
