Answer:
the volume should be in cubic cm so I assumed that you wanted to write the same . then the answer is 5489.07 kg/m^3
Answer:
Explanation:
<u>1) Arrhenius equation</u>
Arrhenius equation shows the relation between activation energy, temperature, and the equilibrium constant.
This is the equation:
Where:
- K is the equilibrium constant,
- A is the frequency factor,
- Ea is the activation energy (in J/mol),
- T is the temperature in kelvins (K), and
- R is the universal constant.
<u></u>
<u>2) Substitute, using the right units, and compute:</u>
- A = 4.20 × 10¹² (dimensionless)
- Ea = 67.0 kJ/mol = 67,000 J/mol
- T = 24.0°C = 24.0 + 273.15 K = 297.15 K
- R = 8.314 J/K mol
Answer:
Aluminum Reacts With Hydrochloric Acid To Produce Aluminum Chloride And Hydrogen Gas. 2Al(s) + 6HCl(aq) -> 2AlCl3(aq) + 3H2(g)What Mass Of H2(g) Is Required From The Reaction Of 0.75 G Of Al(s) With Excess Hydrochloric
Answer:
197.07 K
Explanation:
To solve this problem we can <u>use the PV=nRT equation</u>, where:
- P = 205 kPa ⇒ 205 * 0.00986 = 2.02 atm
- V = 0.0120 m³ ⇒ 0.0120 * 1000 = 12 L
- R = 0.082 atm·L·mol⁻¹·K⁻¹
We<u> input the data</u>:
- 2.02 atm * 12 L = 1.50 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * T
And <u>solve for T</u>:
The northern slope will have the least precipitation if winds blow against a mountain from the south.
<h3>What is Slope?</h3>
This is referred to as the degree of steepness on a surface such as rocky areas etc.
When wind blows on the southern part of a mountains, it gets stuck which is why the northern slope have the least precipitation.
