<u>Answer:</u> The mass of sulfur dioxide gas at STP for given amount is 16.8 g
<u>Explanation:</u>
At STP conditions:
22.4 L of volume is occupied by 1 mole of a gas.
So, 5.9 L of volume will be occupied by = ![\frac{1mol}{22.4L}\times 5.9L=0.263mol](https://tex.z-dn.net/?f=%5Cfrac%7B1mol%7D%7B22.4L%7D%5Ctimes%205.9L%3D0.263mol)
Now, to calculate the mass of a substance, we use the equation:
![\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20moles%7D%3D%5Cfrac%7B%5Ctext%7BGiven%20mass%7D%7D%7B%5Ctext%7BMolar%20mass%7D%7D)
Moles of sulfur dioxide gas = 0.263 mol
Molar mass of sulfur dioxide gas = 64 g/mol
Putting values in above equation, we get:
![0.263mol=\frac{\text{Mass of sulfur dioxide gas}}{64g/mol}\\\\\text{Mass of sulfur dioxide gas}=(0.263mol\times 64g/mol)=16.8g](https://tex.z-dn.net/?f=0.263mol%3D%5Cfrac%7B%5Ctext%7BMass%20of%20sulfur%20dioxide%20gas%7D%7D%7B64g%2Fmol%7D%5C%5C%5C%5C%5Ctext%7BMass%20of%20sulfur%20dioxide%20gas%7D%3D%280.263mol%5Ctimes%2064g%2Fmol%29%3D16.8g)
Hence, the mass of sulfur dioxide gas at STP for given amount is 16.8 g
Answer:
C
Explanation:
There will be a two long hair and two short hair
Answer:
C) It will accelerate.
Explanation:
According to Newton’s second law of motion, when an object is acted on by an unbalanced force, it will accelerate.
An unbalanced force will change the speed or direction (or both) of an object. A change in speed and/or direction is acceleration.
A) is wrong. The object will stop moving only if there is a balanced force in the opposite direction.
B) is wrong. The object will decrease speed only if the unbalanced force has a component opposite to the direction of motion.
d) is wrong. The object will increase speed only if the unbalanced force has a component in the direction of motion.
Polarity is the chemical property based on the electric charge and orientation of the poles. Al−O>H−Br>As−S is arranged in decreasing order of polarity. Thus, option d is correct.
<h3>What is polarity?</h3>
Polarity is a chemical property of the distribution of the electrical charges over their respective atom in the molecule joined by the bonds. The relation between the polarity and the difference in electronegativity is directly proportional.
The electronegativity difference between the elements are:
- Al−O = 1.8
- H−Br = 0.8
- As−S = 0.4
As the electronegativity difference between Al−O = 1.8 is the highest it will have the highest polarity followed by H−Br = 0.8, and As−S = 0.4, with the lowest polarity.
Therefore, option D. Al−O>H−Br>As−S is arranged in decreasing order of polarity.
