Answer:
Gently place 2 fingers of your other hand on the left side of your chest. · Do not use your thumb because it has its own pulse that you may feel. · Count the beats for 30 seconds
Explanation:
Heart rate can be measured using electrocardiography, pulse ... Heart rate is generally expressed as the number of beats per minute (bpm). ... Because perfect accuracy is not always required in pulse-counting,
Answer:
MOLARITY = 0.9554 mol/dm3
Explanation:
525 grams of SnF2 in 3.50 L of wate
To obtain the molarity, calculate the concentration in g/dm3 and then concentration in mol/dm3
Concentration in g/dm3 = 525 g/ 3.50 L
= 525g/ 3.50 dm3
= 150g/dm3 of SnF4
Concnetration in mol/dm3
concentration in mol/dm3 = concentration in g/dm3 / Relative molecular mass of SnF2
RMM of SnF2 = ( 119 + 19*2) = 157 g/mol
= 150g/dm3 / 157g/mol
= 0.9554 mol/dm3 of solution.
The molarity of the solution is therefore 0.9554mol/dm3
Answer:
The half cell reaction when it used as an anode
H₂(g) → 2 H⁺ + 2 e⁻
Explanation:
Standard hydrogen electrode used as reference electrode & acts as an cathode as well as anode half cell.
The half cell reaction when it used as an anode
H₂(g) → 2 H⁺ + 2 e⁻
(Pressure should be 1 bar , temperature 273 k and concentration of HCl = 1 Molar)
Cell representation
H₂(g) , H⁺(1 M)
The standard electrode potential i.e oxidation as well as reduction = 0.00 V
The minerals?
when an acid reacts with a base it forms salts depending on the acids and bases reacted it will determine its formula
for example HCl + NaOH = NaCl + H20
