Answer:

In the case of the Hardwood floor vacuum, you have to use a vacuum cleaner to clean hardwood floors. If you use a hard-bristled broom, it can damage the exterior of Hardwood floors. On the other hand, the vacuum creates less airborne dust and doesn't damage the surface of hardwood floors.When done correctly, the vacuuming process can remove more soil from a floor than a dust mop or broom. ... “The vacuum sucks up and removes all the dust, even the fine dust. It removes all the soil.” Vacuums typically do a better job than mops at reaching dirt in cracks and corners

At 3 atm pressure the volume of gas is 1200ml. What pressure is required to reduce the volume of the gas to 300ml if the tempera
Rufina [12.5K]
States that when a gas is held at a constant temperature and mass in a closed container, the volume and pressure vary inversely. The equation to use is P1V1=P2V2.

Given
V1=200mL×1L1000mL=0.2 L
P1=700 mmHg
V2=100mL×1L1000mL=0.1 L

Unknown
P2

Equation
P1V1=P2V2

Solution
Rearrange the equation to isolate P2 and solve.

P2=P1V1V2

P2=(700mmHg×0.2L)0.1L=1400 L, which must be rounded to 1000 L because all of the measurements have only one significant figure.

ruslelena [56]

Answer:

A) The reaction is exothermic reaction

B) 46 gm CH3CH2OH  = 1236KJ

15.3 gm ch3ch2OH = 1236/46 x 15.3

= 411.10 KJ..........released

therefore  1 KJ = 0.239 K cal

so, 411.10 x 0.239 kcal

= 98.2529 .................. released

c) 54 gm of H2O produced = 1236KJ

so, 42.7 gm H2O produced = 1236/54 x 42.7KJ

= 977.35 KJ released.
