Answer : The final equilibrium temperature of the water and iron is, 537.12 K
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of iron = 560 J/(kg.K)
= specific heat of water = 4186 J/(kg.K)
= mass of iron = 825 g
= mass of water = 40 g
= final temperature of water and iron = ?
= initial temperature of iron = 
= initial temperature of water = 
Now put all the given values in the above formula, we get:
Therefore, the final equilibrium temperature of the water and iron is, 537.12 K
Answer:
water and vinegar
:salad
Explanation:
There is two kind of mixture the heterogeneous and homogeneous mixture.Which water and vinegar is the homogeneous and the salad is heterogeneous mixture based on my example above.
Answer:
Explanation:
The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (group one) has one electron in its outer shell.
For each pair of molecules given in the table below, the correct relationships are identified as follows.
<h3>The relationships between the molecules are given as?</h3>
- These are structural isomers. This is because, they have the same molecular formula (C₆H₁₂) but possess varying structures.
- The given pair of molecules posses similar formula (C₄H₁₀O) and can be superimposed on one another via rotation of the entire molecule, hence they are identical isomers.
- In this case the pair of molecules possess similar molecular formula (C₄H₁₀O) and similar arrangement of atoms. Hence, they are identical isomers.
- This case also features structural isomers. They both contain the same carbon chain with similar formula - C₃H₆BrCl
- These pair as identical isomers. They are also derived from C₃H₆BrCl.
- This pair are called stereoisomers isomers. This is because they contain the same about of molecules but are different in the position of the alcohol (-OH) group. But more importantly, the position of the bonding is the same.
- This set is a functional pair. This is because the composition of the molecules present in each case are different.
- This is also a functional pair.
<h3>What is a molecules?</h3>
A molecule is a bonded collection of atoms that represents the smallest fundamental unit of a chemical compound that may participate in a chemical process.
