Early stages of carbon monoxide poisoning is often confused with seasickness or intoxication.
This is so because some symptons of carbon monoxide (CO gas) poisoning are: irritated eyes, headache, nause, weakness and dizziness. As you can see those symptons are common to seasickness and intoxitation.
Carbon monoxide (CO gas) is colorless and odorless, so it may be difficult to detect the exposure to it before having some symptons of CO poisoning, but it is serious and can result in death. The victim shall be conducted to an open place promptly to receive fresh air and carried to a hospital to receive treatment urgently.
Volume of hydrogen at STP = moles x 22.4 = 7x22.4 = 156.8L
Answer:
Option D. 230 J
Explanation:
We'll begin by calculating the temperature change of the iron. This can be obtained as follow:
Initial temperature (T₁) = 50 °C
Final temperature (T₂) = 75 °C
Change in temperature (ΔT) =?
ΔT = T₂ – T₁
ΔT = 75 – 50
ΔT = 25 °C
Thus, the temperature change of the iron is 25 °C.
Finally, we shall determine the amount of heat energy used. This can be obtained as follow:
Mass (M) = 20 g
Change in temperature (ΔT) = 25 °C
Specific heat capacity (C) = 0.46 J/gºC
Heat (Q) =?
Q = MCΔT
Q = 20 × 0.46 × 25
Q = 230 J
Thus, the amount of heat used was 230 J
It might be more suitable because some data cannot use a graph to show data because there is too much data.
Answer:
Albert Einstein is perhaps most famous for introducing the world to the equation E=mc2. In essence, he discovered that energy and mass are interchangeable, setting the stage for nuclear power—and atomic weapons. His part in the drama of nuclear war may have ended there if not for a simple refrigerator.
