I think the answer is, Thermal? I hope u get it right
Answer:
mass spectrometer
Explanation:
The masses of atoms and molecules can be measured using an instrument called mass spectrometer. This instrument can be used to also measure their relative concentrations. The mass spectrometer functions using the magnetic force that is applied on a charged particle that is in motion.
The answer is B
Because u ask questions first, then do a background research about the topic, then construct hypothesis for the topic, then test with an experiment, analyze results and form conclusions, report the results
Answer:
The mass of water produced is 59.22 g
Explanation:
This is the balanced equation of methane combustion:
CH₄(g) + 2O₂(g) → CO₂(g) +2H₂O(g)
This equation is balanced because we have the same amount of each element at each side of the equation:
Left side:
CH₄= 1C and 4H
2O₂ = (2x2)O = 4O
Total: 1C, 4H, and 4O
Right side:
CO₂ = 1C and 2O
2H₂O = (2x2)H + (2x1)O = 4H + 2O
Total: 1C, 4H, and 4O
Once it is balanced, we know from the equation that 1 mol of methane (1 CH₄) produces two mols of water ( 2 H₂O) when it reacts with oxygen. The mass of a mol of methane is:
Molar mass CH₄ in grams = mass of the carbon atom + mass of the four H atoms.
Molar mass CH₄ = 12 + 4 = 16 g
The same procedure with water:
Molar mass H₂O in grams = mass of the 2 H atoms + mass of the O atom
Molar mass H₂O in grams = 2 + 16 = 18 g
Hence 16 g (1 mol) CH4 will produce 36 (18 x 2)g H2O.
Therefore:
16 g CH4 ⇒ 36 g H20
26.32 g CH4 ⇒ x= 26.32 * 36 / 16 = <u>59.22 g.</u>
Have a nice day!
The answer is Reduction.
What is Reduction ?
- Reduction is a process that involves the addition of hydrogen or any other electropositive element or the removal of oxygen or any other electronegative element, according to classical or older concepts.
- The process through which an atom or an ion gains one or more electrons is known as reduction, according to the electronic idea.
- At the anode, oxidation takes place while reduction happens at the cathode. Anode is a positive electrode in this instance, and cathode is a negative electrode.
An electrochemical cell is a device that can use electrical energy to facilitate chemical reactions inside of it or create electrical energy from those reactions. These gadgets can change chemical energy into electrical energy or the other way around.
Hence, Reduction takes place at the cathode of an electrochemical cell.
