Sink. This is because the density (mass divided by volume) is greater than that of water, and anything that has a greater density than water sinks while anything with a lower density than water floats. Hope this helps.
Answer:
Mass = 11.16 g
Explanation:
Given data:
Mass of hydrogen = 8 g
Mass of oxygen = 10 g
Mass of water produced = ?
Solution:
Chemical equation:
2H₂ + O₂ → 2H₂O
Number of moles of hydrogen:
Number of moles = mass / molar mass
Number of moles = 8 g/ 2 g/mol
Number of moles = 4 mol
Number of moles of oxygen:
Number of moles = mass / molar mass
Number of moles = 10 g/ 32 g/mol
Number of moles = 0.31 mol
now we will compare the moles of hydrogen and oxygen with water.
O₂ : H₂O
1 : 2
0.31 : 2/1×0.31 = 0.62
H₂ : H₂O
2 : 2
4 : 4
Number of moles of water formed by oxygen are less this it will act as limiting reactant.
Mass of water:
Mass = number of moles × molar mass
Mass = 0.62 mol × 18 g/mol
Mass = 11.16 g
Answer:
0.0761.
0.0059.
Explanation:
Hello!
In this case, since the writing of numbers in standard notation given the scientific notation requires adding zeros to the left of the first nonzero digit, for the first number, we need to add two zeros as seven is the third digit position:
0.0761.
Next, we need to add three zeros as 5 would be the fourth digit:
0.0059.
Best regards!
Answer:
in my opinion it wouldn't be regular seasons like what we have now it would be equal in every poles .. there would not be ice in North. [its my opinion though] sorry if I am wrong
Density = mass/volume
Density (iron) = 117 g/15.0 cm³ = 7.80 g/cm³
