Answer:
The ratio of the mass ratio of S to O; in SO, to the mass ratio of S to O; in SO₂, is 2:1
Explanation:
According to the consideration, let us first find the ratio of S and O in both the compounds
For SO:
Let us express it as
For SO₂,
Due to two oxygen atoms in the molecule, the mass of oxygen will be taken two times
Let us express it as
Now, for the ratio of both the above-calculated ratios,
The required ratio is 2:1
Answer:
Iodine
Explanation:
It's in the same group as chlorine.
The coefficient for sulfuric acid wen reaction between calcium phosphate and phosphoric acid occurs is
three (3)
<h2>explanation</h2>
write a balanced chemical equation for the reaction
that is
Ca3(PO4)2 + 3 H2SO4 →2 H3PO4 + 3CaSO4
since coefficient is number in front of a chemical formula the coefficient of H2SO4 is 3
Answer:
W = -120 KJ
Explanation:
Since the piston–cylinder assembly undergoes an isothermal process, then the temperature is constant.
Thus; T1 = T2 = 400K
change in entropy; ΔS = −0.3 kJ/K
Formula for change in entropy is written as;
ΔS = Q/T
Where Q is amount of heat transferred.
Thus;
Q = ΔS × T
Q = -0.3 × 400
Q = -120 KJ
From the first law of thermodynamics, we can find the workdone from;
Q = ΔU + W
Where;
ΔU is Change in the internal energy
W = Work done
Now, since it's an ideal gas model, the change in internal energy is expressed as;
ΔU = m•C_v•ΔT
Where;
m is mass
C_v is heat capacity at constant volume
ΔT is change in temperature
Now, since it's an isothermal process where temperature is constant, then;
ΔT = T2 - T1 = 0
Thus;
ΔU = m•C_v•ΔT = 0
ΔU = 0
From earlier;
Q = ΔU + W
Thus;
-120 = 0+ W
W = -120 KJ
The recipe for an omelet are:
<u>Ingredients</u>
- 1 Egg
- Salt and pepper ( 1 tablespoon )
- Butter ( 1 tablespoon )
<u>Recipe:</u>
- Turn on the heat and place a pan on it.
- Add butter to the pan.
- Crack the egg and whisk it properly.
- Add the whisked omelet onto the pan and stir.
- Add salt and pepper.
<h3>How to illustrate the information?</h3>
When we turn on the heat and place the pan, a heat transfer takes place and heat transfers from one body to another.
When we add butter to the pan, then the temperature of the pan was more than that of the butter.
Since the melting point of butter was less than the temperature of the pan, the the melting of butter takes place.
When we add the egg, the evaporation of the liquid present in the egg yolk and the egg white takes place.
These are the chemical reactions depicted.
