Answer:
His phraseology and his turns of invention are too empirically pseudoscientific for the simplicity of nature.
Answer: The covalent bonds within a molecule are very (strong). However it requires (less) energy to melt a molecular compound than an ionic compound.
This is because the attractive forces between individual molecules are (weaker) than the forces between ions in an ionic compound.
D
Larger surface area speeds up reactions
Rust is an oxide so more oxygen should speed up rate of rust
Temperature also speeds up reactions
+ The humidity affects it aswell
Answer:
- The fuel for nuclear fusion is often uranium
- Nuclear fusion is used to generate electricity at nuclear power plants
Explanation:
The most common nuclear fuel is made up of fissile elements such as Uranium, Neptunium, Plutonium, Americium and Curium, which are fissionable elements, which is when its nucleus is capable of undergoing a fission with neutrons free of any energy.
Nuclear fission can be used both for warlike purposes, as in the construction of atomic bombs, as well as for pacifist purposes, in the construction of reactors for the production of electrical energy.
Answer is: identity of the metal is gold (Au).
ω(Cl) = 35.06% ÷ 100%.
ω(Cl) = 0.3506; mass percentage of chlorine.
If we take 100 grams of the compound:
m(Cl) = ω(Cl) · m(compound).
ω(Cl) = 0.3506 · 100 g.
ω(Cl) = 35.06 g.
n(Cl) = m(Cl) ÷ M(Cl).
n(Cl) = 35.06 g ÷ 35.45 g/mol.
n(Cl) = 0.99 mol; amount of substance.
In molecule MCl₃: n(M) : n(Cl) = 1 : 3.
n(M) = 0.33 mol; amount of unknown metal.
M(M) = m(M) ÷ n(M).
M(M) = (100 g - 35.06 g) ÷ 0.33 mol.
M(M) = 196.8 g/mol; molar mass of the gold.
