We can calculate for the amount of heat released using
the formula:
ΔH = ʎ m
where,
ΔH = heat released
ʎ = latent heat of fusing for water = - 333.55 J/g
m = mass of water = 13.3 g
Calculating:
ΔH = (- 333.55 J/g) * 13.3 g
ΔH = -4,503 J = 1.08 cal
The law of conservation holds true always so there the last two grams has be lost as a gas probably
Answer:
A. electrons simultaneously attracted by more than one nucleus
Explanation:
- Covalent bond is the bond which is formed with the sharing of the electrons between the two atoms which are taking part in the bond. It is generally formed between the atoms with similar electronegativity values.
- It is the bond which is generally occurs within non metals as they share electrons to complete their octet.
- The difference in the electronegativity values of the atoms involving in a covalent bond must not exceed the value of 1.7 .
Thus, the electrons are attracted by the two different nucleus of the atoms that are taking part in the bonding.
<u>So, the correct answer is:- A. electrons simultaneously attracted by more than one nucleus</u>
This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.
I looked this up but hope it helps!
Answer:
Torrey's neighbour is incorrect because increase in kinetic energy is proportional to velocity. If the velocity increases so will the object's kinetic energy. Because the mass is constant, if the velocity increases, so does the kinetic energy.
