Answer:
use the equation Q = mc ΔT
Q = heat energy transferred (joules)
m =mass of the liquid being heated (kilograms)
c = specific heat capacity of the liquid (joule per kilogram Celsius), ΔT = change in temperature (Celsius).
(anode +) Cu⁰(s) - 2e⁻ → Cu²⁺(aq)
Answer:
The correct answer is 4
Explanation:
Boron trifluoride (BF₃) has a molecular geometry (as shown in the image in the question) referred to as trigonal planar; this is because each of the the fluorine atoms/molecules (bonded to the central boron atom) is placed in such a way that they form the three "end points"/"domains" of an equilateral triangle. Hence, the correct option is the last option.
Answer:
Explanation:
Hello,
In this case, the chemical reaction is:
Thus, the reacting moles of hydrochloric acid are computed with the volume of the given solution:
Hence, we perform the proportional factors having the 2:1 molar relationship between hydrochloric acid and hydrogen to find the yielded moles of hydrogen:
Finally, by using the ideal gas equation we obtain the volume for the specified conditions as shown below:
Best regards.
Answer: Conduction, radiation and convection all play a role in moving heat between Earth's surface and the atmosphere. Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface. ... During the day, sunlight heats the ground, which in turn heats the air directly above it via conduction.
