Each section would be 230 centimeters or 2.30 meters long.
<h3>Sectional division</h3>
The original wood pole is 12 meters long.
12 meters = 12 x 100 = 1200 centimeters
It is to be cut into 5 equal sections: 1200/5 = 240 centimeters
But each cut wastes 10 cm of the pole.
240 - 10 = 230 centimeters.
Thus, each section would be 230 centimeters or 2.30 meters long.

Those are types of water on a pH scale 7.0 and above are alkili water and anything under that is acidic
Compound A : SnCl2
the mass ratio of Cl and Sn: 71 g Cl/ 119 g Sn = 0.579 g Cl/ 1 g Sn
Compound B: the ratio of mass of chlorine per 1 g Sn is twice the ratio of chlorine per 1 g Sn in compound A => 1,194 g Cl/ 1 g Sn = 142,086 g Cl/ 119 g Sn
=> the number of chlorine/ 1 atom Sn = 142.086/ 35.5 = 4.
=> the formula of B: SnCl4
Answer:
Explanation:
Carbon Dioxide-CO2
To get molecules, we must convert grams to moles and moles to atoms using Avogadro's number.
Molar mass of CO2=
C:12.0g+O:16.0gx2=44.0g CO2
25.0g CO2 | 1 mol CO2 | 6.02x10 23 molecules CO2
= 3.42x10 23 molecules CO2
1 | 44.0g CO2 | 1 mol CO2
Now to get the number of oxygen atoms.
Since there are 3 atoms in CO2 and 2 of them are oxygen, we will divide by 3 (1.14x10 23) and multiply by 2 (2.28 x10 23)
So the number of oxygen atoms in 25.0 grams of CO2 is 2.28x10 23 or 228 000 000 000 000 000 000 000
Answer:
C 2sp³ + 2sp³ O
Explanation:
Carbon has an atomic number equal to <em>6</em>, so its electronic distribution is:
1s²2s²2p²
Oxygen has an atomic number equal to <em>8</em>, so its electronic distribution is:
1s²2s²2p⁴
In dimethyl ether, the bonds between carbon and hydrogen and carbon and oxygen are saturated, so there will be only sigma bonds. The sigma bonds occurs in hybrids orbitals, and pi bonds on normal orbitals. So, the carbons and the oxygen of that compound has hybridization
2sp³, because they need 4 hybrid orbitals.
So the bond C-O occurs between C 2sp³ + 2sp³ O
