Answer:
''The relationship between air pressure, air density, or altitude? As altitude increases, pressure increases. As altitude increases, air density increases. Air pressure and density are lowest at sea level.''
Explanation:
Answer:
Volume of water it can hold 63000,000 cm³
Mass of water is 63000,000 g.
Explanation:
Given data:
Length of tank = 70.00 cm
Width of tank = 300.00 mm
Height of tank = 300.00 m
Volume of water it can hold = ?
Mass of water = ?
Solution:
First of all we will convert the units into same unit.
Width of tank = 300.00 mm × 1 cm / 10 mm = 30 cm
Height of tank = 300.00 m× 100 cm / 1 m = 30000 cm
Volume of water it can hold:
V = l×w×h
V = 70.00 cm × 30 cm × 30000 cm
V = 63000,000 cm³
Mass of water:
Density of water from literature = 1 g/cm³
d = m/v
1 g/cm³ = m/ 63000,000 cm³
m = 63000,000 g
Hey ! I Don’t see the picture above.
Hello!
The general chemical reaction for the combustion of a fossil fuel is the following one:
C(s) + O₂(g) → CO₂(g)
Now, we use the following conversion factor to go from kilograms of CO₂ to kilograms of O₂, using the molar masses of each compound and the reaction coefficients:
So, for producing 5*10¹² kg of CO₂,
3,64*10¹² kg of O₂ are required.
Have a nice day!
