Explanation:
Potassium and Sodium are both metals on the periodic table. Both elements are found on the s-block of the table. Therefore, it is not possible for both of them to combine to form a compound.
For a compound to form two elements must combine in a definite order to given single product.
The combination is facilitated by a loss, gain or sharing of electrons between two species. This leads to an attraction between the combining species.
Both Sodium and potassium would prefer to lose electrons and there is no reason for them to combine to form a compound.
Explanation:
We know that,
1 mile = 1609.34 m
We need to find how many meters are present in the 12.45 miles. To find it use unitary method as follows :
12.45 mile = 1609.34 × 12.45
12.45 mile=20036.283 meters
or
Hence, this is the required solution.
Answer is B, because CaSO3 only has one S
<u>Answer:</u> The new pressure will be 101.46 kPa.
<u>Explanation:</u>
To calculate the new pressure, we use the equation given by Gay-Lussac Law. This law states that pressure is directly proportional to the temperature of the gas at constant volume.
The equation given by this law is:
where,
are initial pressure and temperature.
are final pressure and temperature.
We are given:
By using conversion factor:
Putting values in above equation, we get:
Hence, the new pressure will be 101.46 kPa.
