Answer:
A
Explanation:
because B is wrong as it doesn't have the same mass number. C is wrong as it has different number of neutrons. D is wrong as it has more neutrons than protons.
Answer:
The atoms are separating, and sublimation is happening.
Explanation:
I think the correct answer from the choices listed above is option C. The process that describes a chemical property of a substance is that when <span>sugar burns in air to form water and carbon. Hope this answers the question. Have a nice day.</span>
The procedure for this is the next one:
moles CaC2 = 485 g/64.1 g/mol=7.57
<span>moles H2O = 2 x 7.57 =15.1 </span>
<span>mass H2O = 15.1 mol x 18.02 g/mol=272.8 g
</span>
Answer:
The one with the full load.
Explanation: We can prove this by doing V^2 X M = KE
where V= velocity M= mass and KE= kinetic energy.
is both are traveling at the same speed (let's say 2kmph) and one has a mass of 50 kg with the other having a mass of 100kg.
(plug in the values) . 2^2 X 50 = KE and 2^2 X 100= KE
(simplify) 200=KE and 400=KE
This proves that a dump truck with a larger load (if traveling at the same speed) will always contain more energy than a dump truck with a smaller load.
