Answer:There is no change in identity of the substance and we can visually see a substance being drawn into wires. Hence ductility is not a chemical property, it is a physical property. Some examples of ductile materials, include metals such as copper, aluminium, silver, gold, etc.
Explanation:
14040/4=3510 wheels per 4 nuts
3510/4=877.5 cars per 4 wheels
877 possible cars.
actual yield 850/theortical yield 877=96.92%
Tollen's test is an organic test that determines whether the sample is an adehyde or not. When aldehydes are present, the reaction forms a silver compound which refers to the other name of Tollen's as silver mirror test. The aldehyde among the choices is C. pentanal
Answer: 211 kPa
Explanation:
Given that,
Original pressure of gas (P1) = 125 kPa
Original volume of cylinder (V1) = 760 cm3
New pressure of gas (P2) = ?
New volume of cylinder (V2) = 450 cm3
Since pressure and volume are given while temperature is held constant, apply the formula for Boyle's law
P1V1= P2V2
125 kPa x 760 cm3= P2 x 450 cm3
95000 kPa•cm3 = 450 cm3•P2
Divide both sides by 450 cm3
95000 kPa•cm3/450 cm3 = 450 cm3•P2/450 cm3
211.1 kPa = P2
[Round the value of P2 to 3 significant numbers. Hence, P2 becomes 211 kPa]
Thus, the new pressure within the cylinder is 211 kPa
The fertilizer they're putting down on the fields, will eventually run into waterways and contaminate the water and make the PH levels out of wack and cause the water to be polluted, it will also cause coral bleaching
