So to solve this you need to know Charles’s law which is: V1/T1=V2/T2. Where T1 and V1 is the initial volume and Temperature and V2 and T2 is the temperature and volume afterwards. So first plug in the numbers you are given. V1= 1.55L T1= 32C° V2= 755mL T2=?. Since your volumes are two different units you change 755mL to be in L so that would be 0.755 L. And since your temp isn’t in Kelvin you do 273+32= 305K°. You then would rearrange your equation to solve for T2 which is V2T1/V1. Then you plug in your numbers (0.755L)(305K)/1.55L. Then you solve and would be 148.5645161 —> 1.49 x 10^2 K
It becomes "ion". anion or cation.
Answer:
4.921.
Explanation:
- It is an acidic buffer solution;
∵ pH = pKa + log[salt]/[acid].
<em>∴ pH </em>= - log(1,8 x 10⁻⁵) + log[0.75/0.50] = 4.745 + 0.1761 = <em>4.921.</em>
OK so the answer to your question will be option D. because chemical energy is being transferred as heat and light
The answer is B milliliter
