Hey there!
D = m / V
13.6 = 76.2 / V
V = 76.2 / 13.6
V = 5.602 mL
Answer:
6.0 L
Explanation:
For this question, we can use
P1×V1= P2 × V2
where
P1 (initial pressure)= 0.2 kPa
V1 (initial volume)= 15L
P2 (final pressure)= 0.5 kPa
V2(final volume)= ?
Since we are trying to find final volume, we can rearrange the equation to make V2 the subject.
V2= (P1 × V1)/ P2
V2= (0.2 ×15)/0.5
V2 =6 L
Answer:
Explanation:
The metallic properties of steel would strongly not favor its use in construction of aircraft.
Steel is an alloy of carbon and iron. It is denser and generally weighs more than equivalent amount of aluminum. This would imply that the weight of aircrafts would be much more heavier than usual. Weight is a very key component in construction of aircraft. The lighter the mass, the faster propellers can move the craft and lesser amount of energy used. The weight would be a major problem.
Although alloying iron and carbon improves the resistant of the steel to corrosion, it still cannot be compared to that of aluminium. We would build airplanes that would not be durable for so long and that can readily rust on frequent usage.
A tetrahedral carbon is sp3 hybridized while a linear carbon is sp hybridized.
Carbon is a chemical element with the symbol C and atomic number 6. It is a non-metal and is tetravalent. That atom donates four electrons to form a covalent chemical bond. It belongs to group 14 of the periodic table. Carbon makes up only about 0.025% of the Earth's crust.
Carbon is used in some form in almost every industry in the world. It is used as fuel in the form of coal, methane gas, and crude oil (used to make gasoline). It is used to manufacture all kinds of materials, including plastics and alloys such as steel (a combination of carbon and iron). Carbon is an essential element for all life forms on earth. Carbon uptake and release are part of all plant and animal life, whether these life forms take up carbon to help make food or release carbon as part of respiration. Carbon is in constant motion from place to place.
