The answer should be A. It takes a very small amount of mass to produce a lot of energy which is displayed in Einstein's equation E=mc². E is the amount of energy given off when some mass is converted into energy.
E=the energy given off, m=the mass turned to energy (I think this is sometimes referred to as the mass defect), and c=the speed of light. Nuclear reactions do not fallow the law of conservation of mass since some of the mass is converted into energy.
I hope this helps. Let me know if anything is unclear.
Answer:
4
Explanation: on the left side of the equation there are 4 carbons, to make 4 carbons on the right side of the equation you need 4 of the CO2 molecules.
Answer: Cesium is more reactive toward water than lithium because the ionization energy decreases down the group reactivity increases down the group.
Explanation: Please mark me as brainliest and i hope that helped!
The capability to do work is said to be energy. It can neither be created nor be destroyed according to law of conservation of energy. Energy exist in different forms depends upon the work to be done such as potential energy, kinetic energy, mechanical energy, heat energy etc.
Now, when the guitarist plucks the guitar strings to make sound, he uses mechanical energy and when guitarist plucks the guitar strings guitar produces sound energy also.
Thus, option (d) is the correct answer.
Answer:
Concentration of solution B is
Explanation:
Solution A: Total volume of solution A = (9.00+1.00) mL = 10.00 mL
According to law of dilution,
where and are initial and final concentration respectively. and are initial and final volume respectively.
Here = , = 1.00 mL, = 10.00 mL
So, =
So, concentration of solution A =
Solution B: Total volume of solution B = (2.00+8.00) mL = 10.00 mL
Similarly as above, =
So, concentration of solution B =
Explanation:
Hope this helps:)
