Answer:
Silicon
Explanation:
One of the most similar elements to carbon on periodic table is silicon. Several compounds formed between carbon or silicon and other elements are identical.
Carbon is an element found in life forms as a building block while silicon is a building block of machine components such as semiconductors
Silicon is an element that can sustain bonds, similar to carbon bonds and it is situated directly under carbon on the periodic table
Answer:
Hi
The water molecule is composed of three atoms: an oxygen atom and two hydrogen atoms. Very strong electromagnetic forces hold the atoms inside the molecule.
A parallel electromagnetic attraction exists between the molecules individually. Water molecules are constantly moving and continuously form and break bonds with other molecules. As the temperature rises, the molecules move faster and the bonds weaken, changing their state to gas. This is called the boiling point. At this stage, the distance between water molecules is large and intermolecular bonds are almost non-existent.
Explanation:
Answer:
<u>One Electron</u> is transferred.
Explanation:
The reaction is as follow,
<span> AgNO</span>₃<span> + Na </span>→ <span>NaNO</span>₃<span> + Ag
Reduction of Ag;
AgNO</span>₃ + 1 e⁻ → Ag
Oxidation State +1 0
Oxidation of Na;
Na → Na⁺ + 1 e⁻
Oxidation State 0 +1
Result:
Therefore, Sodium transfers one electron to silver to reduce it.
The signs of ΔS° and ΔH° will be negative.
A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat.
Combustion reactions must involve O2 as one reactant.
Consider the combustion of butane gas:
C₄H₁₀(g ) + 13/2O₂(g) → 4CO₂(g) + 5H₂O(g)
4 + 13/2 4 + 5
10.5 mol -------------> 9 mol
As the number of moles decreases entropy will decrease
so ΔS° = negative
since this example for combustion reaction heat is released (exothermic)
so ΔH° = negative.
