By determining the period that the element is in. For example, Calcium is in period 2 therefore its valence electron is located on energy level 2.
Answer:
1.15 atm
Explanation:
According to Dalton's law of partial pressures, the total pressure is the sum of all the partial pressures of the gases present in the mixture.
Therefore we have:
Total pressure = partial pressure of carbon monoxide + partial pressure of oxygen + partial pressure of carbon dioxide
We were given the following:
Total pressure = 2.45 atm
Pressure of oxygen = 0.65 atm
Pressure of carbon monoxide = x
Pressure of carbon dioxide = 0.65 atm
Therefore:
2.45 = x + 0.65 + 0.65
2.45 = x + 1.3
x = 2.45 - 1.3
x = 1.15 atm
Answer:
The correct answer is option C, that is, has an irritating odor and is colorless.
Explanation:
Sulfur dioxide refers to a gas. It has a nasty, sharp smell and is invisible. It associates with other components to produce harmful compounds like sulfurous acid, sulfuric acid, and sulfate particles. It is the chemical compound with the formula SO. At standard temperature, it is a toxic gas with an irritating and pungent smell. The gas is released naturally by the volcanic activity.
If we draw the lewis structure, we can see that all Cl
atoms are all connected to the B atom. Now Cl atoms has 7 electrons each on its
outermost shell while B can donate 3 electrons. So by octet rule, each Cl will
gain 1 electron each from the B atom. From the Lewis structure, we can see that
there are actually No Lone pairs on the central atom.
