Mammals are affected through an increase in the number of cells and not in their size.
Hello!
The pressure of the gas when it's temperature reaches 928 °C is 3823,36 kPa
To solve that we need to apply
Gay-Lussac's Law. It states that the pressure of a gas when the volume is left constant (like in the case of a sealed container like an aerosol can) is proportional to temperature. This is the relationship derived from this law that we use to solve this problem:
Have a nice day!

Answer:
Mass = 23.95 g
Explanation:
Mass of iron = 16.7 g
Mass of iron(iii) oxide formed = ?
Solution:
Chemical equation:
Fe + 3O₂ → 2Fe₂O₃
Number of moles of iron:
Number of moles = mas/ molar mass
Number of moles = 16.7 g/ 55.85 g/mol
Number of moles = 0.3 mol
Now we will compare the moles of iron and iron oxide.
Fe : Fe₂O₃
4 : 2
0.3 : 2/4×0.3 = 0.15 mol
Mass of iron(iii) oxide:
Mass = number of moles × molar mass
Mass = 0.15 mol × 159.69 g/mol
Mass = 23.95 g
