Fusion and fission are nuclear reactions that convert a small amount of matter into a large amount of energy.
The fusion reaction is the reaction in which the molecules combine and form energy. The fission reaction is the decomposition nuclear reaction where the matter is degraded into a small entity and the energy is released.
The energy is not converted into matter in both reactions. There is no splitting or combination of nuclei in both reactions.
Thus, the small amount of matter is converted into a large amount of energy is correct.

The answer would be gas.
(1) An atom is electrically neutral.
(2) An atom is mostly empty space.
(3) The nucleus of an atom is negatively
charged.
(4) The electrons in an atom are located in
specific shells.
Answer;
-(2) An atom is mostly empty space.
Experiment
-Rutherford conducted the "gold foil" experiment where he shot alpha particles at a thin sheet of gold. The conclusion that can be drawn from these experiment is that an atom is mostly empty space.
-Rutherford found that a small percentage of the particles were deflected, while a majority passed through the sheet. This caused Rutherford to conclude that the mass of an atom was concentrated at its center, as the tiny, dense nucleus was causing the deflections.

Answer: It is a Heterogeneous mixture.
The beaker contains a mixture of three solids, namely flour, sugar, and baking soda. These components retain their properties in the mixture and are not chemically combined.
The contents of the beaker can be described as a mixture. A mixture is a combination of two or more substances that are not chemically combined. In this case, the beaker contains flour, sugar, and baking soda. These are solid substances that maintain their own properties in the mixture. They're simply combined in the same space (the beaker), but they are not interacting on a molecular level to form a new substance.

b. raising the temperature
c. increasing the concentration
d. adding more of a substance to a mixture
The action that could slow a chemical reaction rate is adding more of a substance to a mixture. The answer is letter d. It does not give time for the rest of the reactants to be consumed because you are adding more of it causing to slow the reaction.
Answer: 0.469 J / g°C
Explanation:
1) Data:
m = 0.158 kg
Q = 2,150.0 J
ΔT = 61.0°C - 32.0°C
Cs = ?
2) Formula:
Q = m×Cs×ΔT
3) Solution
i) Solve for Cs: Cs = Q / [m×ΔT]
ii) Plug in the data and compute
Cs = 2,150.0 J / [158 g × (61.0°C - 32.0°C) ] = 0.469 J / g°C
A. FeS
B. Fe2S3
C. Fe2(SO3)3
Chemical formula of iron (III) sulfide is Fe₂S₃.
A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus and minus signs.
We can write a chemical formula by following steps-
1. Write both the atoms that are present in the chemical compound.
2. Write the valencies of both the atoms that are present in the chemical compound.
3. Now cross multiply both the atoms such that 1 atom's valency goes to the subscript of another atom and vice versa.
Given,
oxidation state of Fe = +3
Valency of Fe = 3
Valency of sulphide ion = 2
When we cross multiply both the atom's valencies we get chemical formula of iron (III) sulfide as Fe₂S₃.
Therefore, chemical formula of iron (III) sulfide is Fe₂S₃.
