Answer: Oxalic Acid is and
Arrhenius Acid.
Explanation: According to
Arrhenius Theory of acid and base, "Acid is any substance which when dissolved in water produces H⁺ Ions".
Therefore, Oxalic Acid is a diprotic substance, which is capable of donating protons in water. This acidity of oxalic acid can be dedicated to the stability of
conjugate base, this stability comes from resonance of the negative charges on
Oxalate ion. Below reaction shows the dissociation of Oxalic Acid into Protons and Oxalate Ion.
Answer:
The density of the substance is 3.9 grams per cubic centimeter.
Explanation:
Given mass=27.3 grams
volume=7 cubic centimeter
We need to find the density.
Density of a substance can be calculated by dividing mass of substance by volume of a substance
Hence Density of the substance is 
.
Answer:
For Mass N, Mass H, and Mass O, the mass is 28.0 g N, 4.0 g H, and 48.0 g respectively
Explanation:
The computation of the mass of each element is given below:
As we know that
A1 mole of ammonium nitrate i.e. 2 mol N, 4 mol H, 3 mol
Now we multiply each of above by the molar masses
For N
= 14.0 g/mol × 2
= 28.0 gN
For H
= 1.0 g/mol × 4
= 4.0 gN
ANd, for O
= 16.0 g/mol × 3
= 48.0 gN
Hence, For Mass N, Mass H, and Mass O, the mass is 28.0 g N, 4.0 g H, and 48.0 g respectively
As reactant concentration decreases, the forward. reaction slows. As product concentration increases, the reverse reaction becomes faster. The forward. reaction will continue to slow and the reverse reaction will continue to increase until they are the same.Then the situation will be at equilibrium.
Answer:
Explanation:
Formula
Heat = m * c * delta t
t = temperature in centigrade.
The first thing you have to do is convert kelvin degrees to centigrade. The conversion factor is - 273. The formula is degrees centigrade = degrees kelvin - 273. It is easier to understand with a couple of examples.
- 290o K = 290 - 273 = 17
- 325. K = 325 - 273 = 52
Solution
Heat = 100.0 grams * 4.18 J/g*C * (52 - 17)
Heat = 100 * 4.18 * 35
Heat = 14630 Joules
But you want kj
Heat = 14630 / 100 = 14.63
Answer
Heat = 14.6 kj
