Answer:
4, 3 , 2 and 6
Explanation:
The reaction equation is given as;
NH₃ + O₂ → N₂ + H₂O
Now, we need to balance the reaction equation;
NH₃ + O₂ → N₂ + H₂O
put the numbers a,b,c and d;
aNH₃ + bO₂ → cN₂ + dH₂O
We need to balance the equation algebraically, ;
Conserving N;
a = 2c
Conserving H;
3a = 2d
Conserving O;
2b = d
Now, let c = 1, a = 2, d = 3 and b =
multiply through by 2;
a = 4, b = 3, c = 2 and d = 6
Insert the parameters:
4NH₃ + 3O₂ → 2N₂ + 6H₂O
We are given the following data.amount of oxygen gas mixed=108 grams molar mass of oxygen gas 32 g/mol volume of c3h8ch8.
Answer:
i took the test but failed and just got that question right so b
Explanation:
Answer:
Explanation:
= Half-life of carbon = 5700 years
t = Time at which the remaining mass is to be found = 10400 years
= Initial mass of carbon = 11 g
Decay constant is given by

Amount of mass remaining is given by

The amount of the substance that remains after 10400 years is
.
Dissociation of NaCl in water is given as below,
NaCl ₍s₎ → Na⁺ ₍aq₎ + Cl⁻ ₍aq₎
According to this balanced equation the moles on RHS and LHS are as,
Moles on LHS,
NaCl ₍s₎ = 1 Mole
Moles on RHS,
Na⁺ ₍aq₎ = 1 Mole
Cl⁻ ₍aq₎ = 1 Mole
Result:
<span>When one mole of sodium chloride dissociates in water, it produces 2 Moles of Ions.</span>
