At room temperature, water will condense to form liquid water.
1 mole of methane reacts with 2 moles of oxygen to form 1 mole of oxygen.
10 ml (0.445 moles) of methane will react with 20 ml (0.89 moles) of oxygen to form 10 ml (0.445 moles) of carbon dioxide.
Hence, the resulting mixture will contain 10 ml of unreacted methane and 10 ml of carbon dioxide.
The total volume of the mixture will be 20 ml.

Answer:
The perimeter of the garden is 14 yard.
Step-by-step explanation:
Consider the figure:
Each unit on the grid represents yard.
From the figure we can find that:
The length of FA is 3.5 yard
The length of EF is 3.5 yard
The length of DX is 2 yard
The length of CD is 2 yard
The length of CB is 1.5 yard
The length of AB is 1.5 yard
To find the perimeter of the garden we need to add all the length as shown:
Perimeter = FA + EF + DX + CD + CB + AB
Perimeter = 3.5 + 3.5 + 2 + 2 + 1.5 +1.5
Perimeter = 14 yards
Hence, the perimeter of the garden is 14 yard.

Answer:
22.0 inches
Step-by-step explanation:
Arc length = (2)()(radius)()
AR = (2)(3.14)(6)(210/360)
Multiply (2)(3.14)(6) to equal 37.60.
Then divide 210 by 360 to get 0.58333
Lastly multiply 37.68(0.58333) to get 21.98 inches which can be rounded to 22.0 inches.
