Answer:
The Carbonate (CO2−3) Ion
Unlike O3, though, the actual structure of CO32− is an average of three resonance structures. 2. Carbon has 4 valence electrons, each oxygen has 6 valence electrons, and there are 2 more for the −2 charge. This gives 4 + (3 × 6) + 2 = 24 valence electrons
Explanation:
The absolute temprature is the limit to the highest and lowest temprature while the kinetic energy is the amunt of energy acquired by molecule to aid movement
Answer:
The combining capacity or power of iron in FeCl3 is +3
Explanation:
The combining capacity or power of an atom of an element is the charge which that atom possesses when it combines with other atoms to form compounds. It is also known as valency or valence.
To determine the combining capacity of iron in FeCl3, the following steps are followed:
1. Group 7 elements have a combining capacity of -1, therefore, the combining capacity of Chlorine in FeCl3 is -1
2. The sum of oxidation numbers of a neutral compound is zero, therefore, Fe + 3 × Cl = 0
Let, the combining capacity of Iron be y.
y + (-1 × 3) = 0
y - 3 = 0
y = +3
Therefore, the combining capacity of iron in FeCl3 is +3
Answer:
What are the correct coefficients when this chemical equation is
balanced? *
P4 + 02 P2O5
<h2>1, 5, 2</h2>
Explanation:
For this reaction we have a combination reaction. Balancing Strategies: This combination reaction is a lot easier to balance and if you can get an even number of oxygen atoms on the reactants side of the equation.
Explanation:
Al2O3
16=molar mass of one oxygen atom
Number of moles: mass/molar mass
Mol of O3: 19÷(16*3) = 0.40 g/mol
mole ratio
0.40: 3 (oxygen)
0.27: 2 (aluminum)
Mass = molar mass*mole
0.27*(27*3)= 21.87g
