The average (mean) is equal to the sum of all the data values divided by the count of values in the data set.
Average = Sum / Count
= 48 / 3
= 16
Answer:
Nitrates compared to sulphates are much more soluble therefore won't form precipitates easily.
<u>Answer:</u> The change in temperature is 84.7°C
<u>Explanation:</u>
To calculate the change in temperature, we use the equation:
where,
q = heat absorbed = 1 kCal = 1000 Cal (Conversion factor: 1 kCal = 1000 Cal)
m = mass of steel = 100 g
c = specific heat capacity of steel = 0.118 Cal/g.°C
= change in temperature = ?
Putting values in above equation, we get:
Hence, the change in temperature is 84.7°C
Answer: it is likely soluble in water
It will likely light up a bulb in a conductivity apparatus
It will likely have a high melting point
Explanation:
Explanation:
In a chemical reaction, the atoms and molecules produced by the reaction are called products.
In a chemical reaction, only the atoms present in the reactants can end up in the products. No new atoms are created, and no atoms are destroyed.
In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
