Solubility<span> is a chemical property referring to the ability for a given substance, the solute, to dissolve in a solvent. It has units of grams of the substance per grams of solvent. We calculate the mass as follows:
311 g AgNO3 / 100 g water (350 g water) = 1088.5 g AgNO3
It can be rounded of to 1100 g of AgNO3. Therefore, option B is the correct answer.</span>
Answer:
1.4 × 10² mL
Explanation:
There is some info missing. I looked at the question online.
<em>The air in a cylinder with a piston has a volume of 215 mL and a pressure of 625 mmHg. If the pressure inside the cylinder increases to 1.3 atm, what is the final volume, in milliliters, of the cylinder?</em>
Step 1: Given data
- Initial volume (V₁): 215 mL
- Initial pressure (P₁): 625 mmHg
- Final pressure (P₂): 1.3 atm
Step 2: Convert 625 mmHg to atm
We will use the conversion factor 1 atm = 760 mmHg.
625 mmHg × 1 atm/760 mmHg = 0.822 atm
Step 3: Calculate the final volume of the air
Assuming constant temperature and ideal behavior, we can calculate the final volume of the air using Boyle's law.
P₁ × V₁ = P₂ × V₂
V₂ = P₁ × V₁ / P₂
V₂ = 0.822 atm × 215 mL / 1.3 atm = 1.4 × 10² mL
The given blanks can be filled with meteorology, atmosphere, biosphere, SI, and scientific notation.
In the field of meteorology, scientists measure the pressure, temperature, and humidity. Their measurements come from the characteristics of the atmosphere, and hydrosphere, and they look at how the weather influences the biosphere and the geosphere. The units of their measurements come from SI and the metric system. The numbers usually are not large, so scientific notation is not used.
Answer: d-orbitals account for the sulphur- oxygen double bond.
Explanation:
Looking at the nature of bonding in SOCl2, the sulphur is bonded to two chlorine atoms and one oxygen atom. The sulphur has a lone pair of electrons. There are four bonds and four electron pairs if we don't count the lone pair on sulphur. This leads to a tetrahedral shape. However, if we invoke a valence state in which d orbitals are involved and the thionyl chloride is still sp3 hybridized, then we will have one electron in the d-orbital which overlaps with a 2p electron from oxygen to form the double bond. The four sp3 orbitals accommodate eight electrons including the lone pair on sulphur while the d-orbital accommodates the remaining two electrons from the pi-bond thereby completing the ten electrons.
