Answer:
C. Horizontal
Explanation:
The type of cylinder arrangement that is shown in the figure is "Horizontal"
The arrangement is actually horizontal which is known to be horizontally opposed engine. Such engine is known as flat engine. It's a piston engine that has the cylinders located on either side of a crankshaft. It is usually located at the central crankshaft. This type of engine has performance advantage over others.
Answer:
1.25 cm/day
Explanation:
An air thickness , (l) = 0.15 cm
Air Temperature =
Mass Diffusion coefficient (D) =
If the air pressure
We are to determine how fast will the water level drop in a day.
From the property of air at T = 20° C
from saturated water properties.
The mass flow of can be calculated as:
where:
R(constant) = 8.314 kJ/mol.K
Since 1 mole = 18 cm ³ of water
will be:
Again:
Converting the above value to cm/day: we have:
= 1.25 cm/day
∴ the rate at which the water level drop in a day = 1.25 cm/day

Answer:
Rubber:Covalent bonding
Barium sulfide:ionic bonding
Solid xenon: Van daar Waal bond.
Bronze:Metallic bond
Nylon:Covalent bonding
Aluminum phosphate: mixture of ionic and covalent bond
Explanation:
Rubber is mainly composed of isoprene which is predominantly covalent bond
Barium sulphide is predominantly ionic bonding
Is xenon is inert its bond is van daar Waal
Bronze is an alloy of metal usually held by metallic boding
Nylon:covalent bonding
Aluminium phosphate have a mixture of covalent and ionic bond
Answer:
10.41 kg
Explanation:
The gas state equation is:
p * V = n * R * T
For this equation we need every value to be in consistent units
1.5 bar = 150 kPa
5 C = 278 K
n = p * V / (R * T)
n = 150000 * 10 / (8.31 * 278) = 649 mol
Multiplying the amount of moles by the molecular weight of the gas we obtain the mass:
m = M * mol
m = 16.04 * 649 = 10410 g = 10.41 kg
