Answer:
B I have taken the quiz already 90%
Answer: how much mass is in a certain amount of space
Explanation: density is g/mL; therefore it’s the mass (g) in a certain amount of space (mL)
You can put magnets on a fridge
Answer:
Mass = 5.56 g
Explanation:
Given data:
Mass of Cl₂ = 4.45 g
Mass of NaCl produced = ?
Solution:
Chemical equation:
2Cl₂ + 4NaOH → 3NaCl + NaClO₂ + 2H₂O
Number of moles of Cl₂:
Number of moles = mass/molar mass
Number of moles = 4.45 g/ 71 g/mol
Number of moles = 0.063 mol
Now we will compare the moles of Cl₂ with NaCl.
Cl₂ : NaCl
2 : 3
0.063 : 3/2×0.063 =0.095 mol
Mass of NaCl:
Mass = number of moles × molar mass
Mass = 0.095 mol × 58.5 g/mol
Mass = 5.56 g
Explanation:
biotic factors are the things which have life like animals and plants
And Abiotic factors are the things which don't have life like air,stone and river
