Answer:
HI(aq) + NaOH(aq)-------------> NaI(aq) + H2O(l)
Explanation:
The molecular reaction between hydroiodic acid and aqueous sodium hydroxide is shown above. It is a reaction of one mole of hydroiodic acid with one mole of sodium hydroxide to yield salt and water only. It is a neutralization reaction. Hydrogen iodide dissolves in water to produce hydronium ions which agrees with Arrhenius description of acids. Hydroiodic acid is a strong acid with PKa of -9.3
Hydrogen (H2). A single replacement reaction occurs where the metal bonds with Cl and replaces the metal-acting Hydrogen
N2 + 3H2 ----> 2NH3
! mole of nitrogen reacts with 3 moles of hydrogen to give 2 moles of ammonia.
So by proportion number of moles NH3 obtained from 0.60 moles of N2 =
0.6 *2 = 1.2 moles Answer
Answer:
The smaller a particles the higher the surface area to volume ratio
Explanation:
In a grain silo, there are lots of minute dust grain particles and chaff floating in the air. The silo is important in keeping the grains dry hence there is little moisture. These particles, when concentrated, are therefore highly combustible and the slightest spartk can cause a spectacular explosion.
Answer:
A)3410K
B)5678.6 °F
Explanation:
✓ To convert Celcius to Kelvin expression below can be used
K= °C + 273
We were given T=3137 °C
= 3137 + 273= 3410K
✓To convert Celcius to Fahrenheit, expression below can be used
°F =(°C × 9/5) + 32
We were given T=3137 °C
°F= (3137 × 9/5) + 32
= 5646.6+32
=5678.6 °F
