Answer:
32.1 g
Explanation:
Step 1: Write the balanced combustion reaction
C₄H₁₀ + 6.5 O₂ ⇒ 4 CO₂ + 5 H₂O
Step 2: Calculate the moles corresponding to 97.4 g of CO₂
The molar mass of CO₂ is 44.01 g/mol.
97.4 g × 1 mol/44.01 g = 2.21 mol
Step 3: Calculate the moles of butane that produced 2.21 moles of carbon dioxide
The molar ratio of C₄H₁₀ to CO₂ is 1:4. The moles of C₄H₁₀ required are 1/4 × 2.21 mol = 0.553 mol
Step 4: Calculate the mass corresponding to 0.553 moles of C₄H₁₀
The molar mass of C₄H₁₀ is 58.12 g/mol.
0.553 mol × 58.12 g/mol = 32.1 g
D, obviously. All living things are made of one or more cells, therefore non-living things aren’t made of cells
Answer: 0.01645
Explanation:to long tosovles.
An element is a substance made entirely from one type of atom. For example, the element hydrogen is made from atoms containing a single proton and a single electron.
Answer:
Oxygen 16 has 8 protons and 8 neutrons while Oxygen 18 has 8 protons and 10 neutrons . These are isotopes of oxygen i.e same no. of protons but different no. of neutron .
