Answer:
CO
Explanation:
the rest are elements. CO is made up of one carbon atom and one oxygen atom
Explanation:
The given data is as follows.
,
Work produced per kJ of heat extracted from hot reservoir = 0.45 kJ = Efficiency
If the device is Carnot cycle then its efficiency will be maximum and its value will be equal to
Using this relation we will calculate the efficiency as follows.
Efficiency =
=
= 0.928
Hence, it means that this type of device is possible and the claim is also believable.
Be careful on this one! Mass is always conserved, based on the law of conservation of mass. Since their was a change in state, we went from a solid to a gas, so, the weight would be lighter, not the mass.
Same amount of mass.
Answer:
B.109.5
Explanation:
Bond angle :This is the angle between the two bonds present in the atoms or molecule.
Sulphur difluoride(SF2) has a bond angle of 109.5 degrees.
