In the compound nh3, nitrogen has an oxidation number of 3+ and hydrogen has an oxidation number of -1
The molecule NH3 have a neutral charge so the number of oxidation number of it's component must be equal to zero. The molecule NH composed of 1 nitrogen and 3 hydrogens. If the nitrogen oxidation number is 3+, then hydrogen would be:
1* N + 3*H=0
1*+3 +3*H=0
3H= -3
H= -1
Its probably becuase of the amount of minerals found in the ocean floor.Salt just so happens to be a major one.not only that,but the amount of salt that the human body emits while while outside,normally by bodies of water,it could also be that.
<em>Electrolytes</em> are substances -minerals- that conduct electricity once they are dissolved in water. Some examples include Na⁺ (Sodium), Ca⁺² (Calcium), PO₄⁻³ (Phosphate) and Mg⁺² (Magnesium).
They are important because of the rols they play in our organism: The electrical charges they carry are what allow muscles to contract and nerve impulses to be transmitted. Without proper muscle contractions or nerve transmissions we would die.
We do not need to drink Gatorade to get electrolytes. It's true that sport drinks contain electrolytes, but those electrolytes can also come from different sources in our everyday diet, such as salt or fruits and vegetables.
It would use rapid combustion
Answer:
Explanation:
Equation of reaction:
2HCl → H₂ + Cl₂
From the equation of reaction,
From ideal gas equation,
PV = nRT
P = pressure of the ideal gas
V = volume of the gas
n = number of moles
R = ideal gas constant
T = temperature of the gas
At STP,
P = 1.0atm
T = 273.15K
R = 0.082J/mol.K
PV = nRT
1 .0 × 11.2 = n × 0.082 × 273.15
11.2 = 22.398n
n = 11.2 / 22.398
n = 0.50mole
From the equation of reaction,
2 moles of HCl = 1 mole of Cl₂
X moles HCl = 0.5mole
X = (2 × 0.5) / 1
X = 1 mole of HCL
Number of mole = mass / molar mass
Molar mass of HCl = 1 + 35.5 = 36.5g/mol
Mass = number of mole × molar mass
Mass = 1 × 36.5
Mass = 36.5g
36.5g of HCl is required to to produce 11.2L of Cl₂
