Answer:
SeCl₆ + O₂ → SeO₂ + 3Cl₂
Explanation:
Unbalanced:
SeCl₆ + O₂ → SeO₂ + Cl₂
Count the atoms.
On the left side, we have 1 Se atom, 6 Cl atoms, and 2 O atoms.
On the right side, we have 1 Se atom, 2 O atoms, and 2 Cl atoms.
So everything is balanced except for Cl. To balance, we put a 3 coefficient in front of Cl₂.
SeCl₆ + O₂ → SeO₂ + 3Cl₂
c:
Answer: increases
Explanation:
Increase in the temperature of a reaction system will cause the molecules of the reactants to possess higher kinetic energy which they would use to travel more randomly in the system, colliding more frequently with other excited molecules and with the wall of the containing vessel.
Thus, if temperature is increased, the number of collision per second also increases.
Answer: You will need mountaineering equipment such as ice axes and crampons, clothing such as gloves and headwear, and supplies such as food, a stove to thaw water and the food, and first aid materials.
Explanation: Please mark as brainliest lol!
For each shift, you will earn 12/60*75=15 dollars=60 quarters. If the laundry is 12 quarters per load, you can make 60/12=5 loads. If the laundry is 16 quarters, you can make 60/16=3.75 loads. You can pay only 3 loads.
Answer: When the concentration of HI is tripled then the rate increases by a factor of 9.
Explanation:
The rate of a chemical reaction is the measure of concentration of reactants or the measure of concentration of products with respect to time.
As the rate of decomposition of HI is given as follows.
![Rate = k[HI]^{2}](https://tex.z-dn.net/?f=Rate%20%3D%20k%5BHI%5D%5E%7B2%7D)
When concentration of HI is tripled then the new rate will be as follows.
![R^{'} = k[HI]^{2}\\= k \times (3)^{2}\\= 9k](https://tex.z-dn.net/?f=R%5E%7B%27%7D%20%3D%20k%5BHI%5D%5E%7B2%7D%5C%5C%3D%20k%20%5Ctimes%20%283%29%5E%7B2%7D%5C%5C%3D%209k)
This shows that rate increases by a factor of 9.
Thus, we can conclude that when the concentration of HI is tripled then the rate increases by a factor of 9.
