Answer:
21.344%
Explanation:
For the given chemical reaction, 8 moles of the reactant should produce 4 moles of . However, 195 g of was produced instead. The molar mass of is 61.9789 g/mol.
Thus, the moles of produced = 195/61.9789 = 3.1462 moles
The percent error = [(Actual -Experiment)/Actual]*100%
The percent error = [(4.00 - 3.1462)/4.00]*100% = (0.85376/4.00)*100% = 21.344%
<u>Answer:</u>
An example of a capital good is "the government will open another public school in the area".
<u>Explanation:</u>
A capital good or complicated products and systems or (CoPS) is a reliable commodity used in the manufacturing of goods and services. These are one of three kinds of consumer commodities, while the other two are property and labor.
The three are also commonly referred to as primary production factors.They are recorded on a company's balance sheet as assets, and can be depreciated over time. Capital goods instances include furniture, buildings, machinery, equipment and fixtures.
Answer:
1.2 L
Explanation:
Step 1: Write the balanced equation
Mg + 2 HCl ⇒ MgCl₂ + H₂
Step 2: Calculate the moles corresponding to 2.3 g of Mg
The molar mass of Mg is 24.31 g/mol.
2.3 g × 1 mol/24.31 g = 0.095 mol
Step 3: Calculate the moles of H₂ produced
0.095 mol Mg × 1 mol H₂/1 mol Mg = 0.095 mol H₂
Step 4: Calculate the volume occupied by the hydrogen
We will use the ideal gas equation.
P × V = n × R × T
V = n × R × T/P
V = 0.095 mol × (0.0821 atm.L/mol.K) × 298 K/2 atm = 1.2 L
Answer:The Peruvian west coast bordering the Pacific Ocean is a long desert strip that stretches from the departments of Tumbes in the north bordering Ecuador, to Tacna in the south bordering Chile for a total length of 1,555 miles or 2,500 km. The average temperature from December to April is 25 to 28C or 53 to 59F and the average temperature from May to November is 12 to 15C or 53 to 59F.
The coast covers about 10% of the territory but is home to more than 50% of the population. Large cities such as Lima, the capital, Trujillo, Chiclayo and Tacna are located in the coast. Cities along the coast are the center of economic activity attracting people from the interior of the country looking for economic prosperity.
idk hope this helps !!!!
