Answer:
2:1
Explanation:
The Law of Multiple Proportions states that when two elements A and B combine to form two or more compounds, the masses of B that combine with a given mass of A are in the ratios of small whole numbers.
That is, if one compound has a ratio r₁ and the other has a ratio r₂, the ratio of the ratios r is in small whole numbers.
1. Compound 1
Mass of O = 100.0 - 61.4 = 38.6 g
2. Compound 2
Mass of O = 100.0 - 76.1 = 23.9 g
3. Ratio of the ratios
For example. the compounds might be VO₂ and VO.
If the water molecule was linear instead of bent the water would no longer produce hydrogen bonds.
<u>Explanation:</u>
- Yes, If the water molecule was linear instead of bent the water would no longer produce hydrogen bonds.
- The water would no longer generate hydrogen bonds.
- It will lose its polar features and nearly all of its features will change such as boiling point, water tension and solubility.
- It would be more like to gas, rather than liquid.
- If the water was in the linear, the water would have all the features and it would produce the hydrogen bonds.
Answer:
Hydrogen is the chemical element with the symbol H and atomic number 1. With a standard atomic weight of 1.008, hydrogen is the lightest element in the periodic table.
Explanation:
Answer:
Option A. 1191.49 K
Explanation:
Data obtained from the question include:
The equation for the reaction is given below:
4HCl + O2 —> 2Cl2 + 2H2O
Enthalpy (H) = +280 KJ/mol = +280000 J/mol
Entropy (S) = +235 J/Kmol
Temperature (T) =..?
The temperature at which the reaction will be feasible can be obtained as follow:
Change in entropy (ΔS) = change in enthalphy (ΔH)/T
(ΔS) = (ΔH)/T
235 = 280000/T
Cross multiply
235 x T = 280000
Divide both side by 235
T = 280000/235
T = 1191.49 K
Therefore, the temperature at which the reaction will be feasible is 1191.49 K
The general properties of matter result from its relationship with mass and space. ... Because it occupies space, all matter has volume and impenetrability, since two objects cannot occupy the same space simultaneously.
