Scientific notation for 5,098,000
Answers
So now 5,098,000.
Now we need to move the decimal over to make this problem greater than 1 and less than 10. So if we but the decimal Right after 5 we have 5.098 which is greater than 1 and less than 10.
So now we write it out like this
5.098*10^x
let's find x.
X is how many times we moved the decmal over, in this case 6.So now
5.098*10^6
Does this help?

The volume of the gas at 127.0 °C is 321.28 ml.
What is volume?
The volume of any substance is the total space it occupies.
Given data is
V₁ is 400.0 mL
T₁ is 225.0ºC + 273 = 498 K
T₂ = 127.0ºC + 273 = 400 K
To find V₂
By Ideal gas law
Thus, the volume of the gas at 127.0 °C is 321.28 ml.
Learn more about volume, here:
T₁ = 225.0ºC + 273 = 498 K
V₂ = ?
T₂ = 127.0ºC + 273 = 400 K
V₁ / T₁ = V₂ / T₂
400.0 / 498 = V₂ / 400
498 x V₂ = 400 x 400
498 x V₂ = 160000
V₂ = 160000 / 498
V₂ = 321.28 mL

Cl2(aq) + 2Br-(aq) --> 2Cl- + Br2(aq)
Looking at each substance involved in the reaction:
Cl2 has 0 charge and gains a charge of -1 after the reaction
Br- has a charge of -1 but turns to 0 after the reaction
Cl2 gained an electron which means it is the reduced substance
Br- lost an electron which means it is the oxidized substanced
Consequently, Cl2 is the oxidizing agent and Br- is the reducing agent.
Answer:
Bromine (Br) loses an electron, so it is the reducing agent.
