whixh equals
C4 H12 +O20 > C4O8(g) + H12O12
C4=C4
H12=H12
O20=O20
balanced
Answer:
CuNO3
Explanation:
In order to calculate the empirical formula in this question;
Cu = 50.61% = 50.61g
N = 11.16% = 11.16g
O = 38.23% = 38.23g
Next, we convert each gram unit to moles by dividing by their respective molar mass (Where; Cu = 63.55, N = 14, O = 16)
Cu = 50.61 ÷ 63.55 = 0.796mol
N = 11.16 ÷ 14 = 0.797mol
O = 38.23 ÷ 16 = 2.389mol
Next, we divide each mole value by the smallest (0.796)
Cu = 0.796mol ÷ 0.796 = 1
N = 0.797mol ÷ 0.796 = 1.001
O = 2.389mol ÷ 0.796 = 3.001
Approximately, the simple whole number ratio between Cu, N and O is 1:1:3, hence, the empirical formula is CuNO3.
Answer:
Shampoo < corn syrup < honey
Explanation:
Shampoo flows fairly easily from the bottle, so would say it is the least viscous.
Both honey and corn syrup are quite viscous.
However, honey can range from liquid to solid at room temperature.
I have not seen solid corn syrup, so I would predict that it is less viscous than honey at a given temperature.
The results of Rutherford's experiment were surprising as most of the alpha particles went straight without any deflection
<h3>Rutherford's Gold Foil experiment:</h3>
During the experiment, Rutherford directed beams of alpha particles at the thin gold foil and observed the following things:
- Most of the alpha particles passed straight without any deflection
- Few alpha particles got deflected from their paths on small angles
- Very few alpha particles got deflected from their paths on very large angles
<h3>Results of the experiment:</h3>
- Most of the space inside an atom is empty
- The center of the atom is occupied by a tiny positively charged dense body called a nucleus. Most of the mass of the atom is concentrated in the nucleus
- The electrons revolve around the nucleus in circular orbits and are called planetary electrons
Thus, the results of the experiment were surprising due to the above-stated facts.
