Answer:
The reaction is B. Synthesis
Explanation:
In the case of this reaction, it corresponds to a synthesis where 2 compounds (calcium oxide and water) are combined to form a new one (calcium hydroxide).
<h2>The required "options are (II), (III), and (IV)".</h2>
Explanation:
Postulates of Dalton's atomic theory which are scientifically accepted are:
- Atoms are indestructible.
- Compounds are combinations of different atoms.
- A chemical reaction changes the way atoms are grouped together.
Postulates of Dalton's atomic theory which are not accepted scientifically are:
- All atoms of the same elements are identical.
The theory states that the atoms of the same element are identical in every aspect but it is now scientifically proved that the same element should differ in their mass which is known as isotopes.
Answer:
Heat or electricity in the atmasphere
Explanation:
Answer:
1. The same pattern of phases repeats monthly
2. Waxing moon phases are visible between the new and full moon
6. A full moon appears toward the middle of a lunar month
Explanation:
Moon has eight phases which is used by the ancient people for the identification of date of the month. Phases of moon tells us about the starting, middle and end of the month. At the starting of the month, waxing crescent appears while at the middle of the month, the moon gains its full shape. Phases which occurs between new and full moon is known as waxing.
<u>Answer:</u> The new pressure of CO is 0.09 atm
<u>Explanation:</u>
For the given chemical reaction:
The expression of 
for above equation follows:
.......(1)
We are given:
Putting values in above equation, we get:
Addition pressure of chlorine added = 0.39 atm
Now, the equilibrium is re-established:
Initial: 0.26 0.15 0.66
At eqllm: 0.26-x 0.54 0.66+x
Putting values in expression 1, we get:
So, new pressure of CO = 0.26 - x = (0.26 - 0.17) = 0.09 atm
Hence, the new pressure of CO is 0.09 atm
