Sodium reacts with chlorine as shown in the equation below;
2Na(s) + Cl2(g) = 2NaCl(s)
The molar mass of sodium chloride is 58.44g/mol,
while that of sodium is 23 g/mol.
The moles of sodium cholride formed will be 351 g / 58.44 g = 6.006 moles
The mole ratio of sodium to Sodium chloride is 2 : 2,
therefore the moles of sodium used will be 6.006 moles,
Hence, mass of sodium used, 6.006 × 23 = 138.142 g or 0.1381 kg
i believe the answer would be D. When ordered by atomics mass every eighth element has similar properties.
Body temperature is the main one. blood ph is very important. and reflex reactions. if this was right please give me brainliest
Answer:
D will be the answer of no 43
150 kg will be the answer of no 44
