You just need the number of protons and number of neutrons as the mass of eelctrons is negligible
I am going to be honest i’m good at chemistry but i need the point cause i need help on my history work
The answer is "chemical properties". The original water is split apart by the current
<span>to form its constituent elements, hydrogen & oxygen. This is a chemical change, as </span>
<span>the original water is lost and new substances, H2 & O2, are produced. </span>
<span>Hope this answers your question.</span>
Answer:
Explanation:
The answer is C Enthaply and entropy because temperature plays a big role in reactions
The heat released by reaction : C) -8870 J
<h3>Further explanation</h3>
Given
1.008 g of hydrogen
500.00 g water
The temperature rises 25.00 °C to 29.24 °C
Required
energy required
Solution
Q absorbed by water :
Q = m.c.Δt
Q = 500 g x 4.18 J/g C x (29.24-25)
Q = 8870.08 J
The reaction to produce HCl is an exothermic reaction (releasing heat), so that Q is negative
Q water = -Q HCl = -8870.08 J
