Answer:
7.71 × 10⁻⁴ M/s
Explanation:
The initial rate of the reaction can be expressed by using the formula:
![\dfrac{\Delta [O_2]}{\Delta t}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5CDelta%20%5BO_2%5D%7D%7B%5CDelta%20t%7D)
where the number of moles of O₂ = 
where;
Pressue P = 1.00 atm
Volume V =5.74mL = (5.74 /1000) L
Rate R = 0.082 L atm/mol.K
Temperature = 298 K

= 2.35 × 10⁻⁴ mol
Δ[O₂] = 
Δ[O₂] = 
Δ[O₂] = 0.04626 M
The initial rate = ![\dfrac{\Delta [O_2]}{\Delta t}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5CDelta%20%5BO_2%5D%7D%7B%5CDelta%20t%7D)
= 
= 7.71 × 10⁻⁴ M/s
Answer:
The new molarity is 0.614 M
Explanation:
Formula for dilutions is:
M concentrated . Volume of conc = Volume of dil . M diluted
6.54 M . 249 mL = 416 mL . M diluted
Notice that volume of diluted is = Initial volume + What we added of water
(249mL + 167 mL)
(6.54 M . 249 mL) / 416mL = M diluted → 0.614 M
Answer:
The chemical formula of diphosphorus monoxide is OP2.
I'm not sure if this is correct, but hope it helps! :)
Answer:
I hope the link above will be helpful
On the periodic table everything to the right of the line is a non metal
Everything to the left is a metal. So the line crosses to the right is NM to left is M
