-- Most of the southern part of the state is considered to have
no risk of damage.
-- Most of the upper part of the state is considered to be at risk
for only minor damage.
-- A tiny part of the state, in the 'Big Bend' region in the west, is
considered to be at risk for moderate damage.
Answer:
v ≈ 4.47
Explanation:
The Formula needed = <u>KE = </u>
<u> m v²</u>
<u></u>
Substitute with numbers known:
2000J =
× 200kg × v²
Simplify:
÷100 ÷100 (Divide by 100 on both sides)
2000J = 100 × v²
= v²
20 = v²
√ √ (Square root on both sides)
√20 = √v²
4.472135955 = v (Round to whatever the question asks)
v ≈ 4.47 (I rounded to 2 decimal places or 3 significant figures, as that is what it usually is)
A. is a neutral substance.
Only neutral substances (like pure water) can have a pH of 7.
Answer:

Explanation:
The work (W) done by the gas can be calculated using the following equation:

<u>Where:</u>
p: is the pressure
[tex}V_{f}[/tex]: is the final volume
[tex}V_{i}[/tex]: is the initial volume
In the first process, the work done by the gas is:

Since the volume remains constant, the total work done by the gas is equal to zero.
In the second process, the work done by the gas is:
Now, the total work done by the gas during both processes is:

Therefore, the total work done by the gas during both processes is - 24 kJ.
I hope it helps you!
Constant = 8.314JK⁻¹mol⁻¹
T is for temperature which is 298K
Faraday constant value is 96500C/mol
n is the number of electrons which are transferred in the reaction.
Ecell = E₀cell - RT/nFiN [cathode]/[anode]
Ecell = E₀cell - RT/nF In [PH₂]/[H⁺]²
Ecell = 0.00-8.314 JK⁻¹ mol⁻¹ × 298k/ 2× 96500C/mol In [2.4atm]/ 0.70]²
Ecell = 0.00 - 0.0129 In (2.59)
Ecell = 0.00 - 0.0129 × 0.951
Ecell = -0.0122V
∴Ecell is = -o.0122v
