Answer:
Below.
Explanation:
The balanced equation is:
Ba(CN)2 + H2SO4 ---> 2H(CN) + BaSO4
Answer:
You will generate 0.124 moles of aluminum when you react 0.372 moles of potassium
Explanation:
Determine the reaction:
3K + AlBr₃ → Al + 3KBr
Ratio is 3:1
3 moles of K can produce 1 mol of Al
So, 0.372 moles of K, may produce (0.372 .1) /3 = 0.124 moles of Al
Answer:
116 °C
Explanation:
The given parameters of the Substance Q are;
The boiling point of Q = 445°
The substance <em>Q</em> is a solid at room temperature
Given that <em>Q</em> has a single fixed boiling point, <em>Q</em>, is suspected to be a pure substance, and it will therefore also have a fixed single melting point above room temperature;
Therefore, the best option is option C. 116 °C, which is above a single temperature value above 116 °C
The ignition occurs when a mixture of fuel & oxygen encounter an external heat source with sufficient heat<u> Piloted ignition.</u>
<h3>
What is Piloted ignition?</h3>
When a volatile fuel is close to a nearby local energy source (pilot) and reaches its lower limit of flammability in air, piloted ignition may be possible. The flame that originates in the premixed system spreads outward from the pilot. The first law of thermodynamics for systems with fixed mass only describes the energetics of this process.
<h3>Definition of thermodynamics </h3>
The science of thermodynamics examines how heat, work, temperature, and energy are related. The general topic of thermodynamics is the transfer of energy from one location or form to another. The fundamental idea is that heat is a type of energy that is equivalent to a specific quantity of mechanical labor.
