Question

consider the thermal decomposition reaction for magnesium sulfate monohydrate below: mgso4·h2o(s)→mgso4(s)+h2o(g) which one of the following is the anhydrate in the above reaction? so4²- mgso4 h2o mg²+ mgso4·h2o question 2 (1 point) the simplest formula always indicates __________. how many of each atom are in a molecule the isotope of each element in a compound which atoms are attached to which in a molecule the geometry of a molecule the lowest whole - number ratio of different atoms in a compound

Explanation:

• For the first question: An anhydrate is a compound without water. In the reaction \(MgSO_{4}\cdot H_{2}O(s)\to MgSO_{4}(s)+H_{2}O(g)\), \(MgSO_{4}\) has no water of crystallization, while \(MgSO_{4}\cdot H_{2}O\) is a hydrate (\(SO_{4}^{2 -}\) is an ion, \(H_{2}O\) is water, \(Mg^{2+}\) is an ion).
• For the second question: The simplest formula (empirical formula) of a compound gives the lowest whole - number ratio of different atoms in a compound. A molecular formula shows how many of each atom are in a molecule. Isotopes are not indicated by formulas. Structural formulas show which atoms are attached to which. Molecular geometry is not shown by the simplest formula.

Answer:

1. \(MgSO_{4}\)
2. the lowest whole - number ratio of different atoms in a compound
