Answer:
- The answer is the concentration of an NaOH = 1.6 M
Explanation:
The most common way to solve this kind of problem is to use the formula
In your problem,
For NaOH
C₁ =?? v₁= 78.0 mL = 0.078 L
For H₂SO₄
C₁ =1.25 M v₁= 50.0 mL = 0.05 L
but you must note that for the reaction of NaOH with H₂SO₄
2 mol of NaOH raect with 1 mol H₂SO₄
So, by applying in above formula
- (C₁ * 0.078 L) = (2* 1.25 M * 0.05 L)
- C₁ = (2* 1.25 M * 0.05 L) / (0.078 L) = 1.6 M
<u>So, the answer is the concentration of an NaOH = 1.6 M</u>
Answer:
helium and neon are both noble gases their outermost shells are full or stable the elements will agree with the statement s above
Answer:
C
Explanation:
1mL = 1cm
3 * 1 = 3cm³
We use "³" because we are working with units that represent volume.

The balloon will reach its maximum volume and it will burst.
Given:
- A weather balloon at sea level, with gas at 65.0 L volume, 745 Torr pressure, and 25C temperature.
- When the balloon was taken to an altitude at which temperature was 25C and pressure was 0.066atm its volume expanded.
- The maximum volume of the weather balloon is 835 L.
To find:
Whether the weather balloon will reach its maximum volume or not.
Solution:
The pressure of the gas in the weather balloon at sea level = 

The volume of the weather balloon at sea level = 
The temperature of the gas in the weather balloon at sea level:

The balloon rises to an altitude.
The pressure of the gas in the weather balloon at the given altitude:

The volume of the weather balloon at the given altitude = 
The temperature of the gas in the weather balloon at the given altitude:

Using the Combined gas law:

The maximum volume of the weather balloon= V = 835 L

The volume of the weather balloon at a given altitude is greater than its maximum volume which means the balloon will reach its maximum volume and it will burst.
