Answer:
Out of personal experience (lol), I'd say the stick of butter is hard, cold, and very smooth at first. Once heated up or just kept at room temp for a while, it becomes mushy.
Hope I helped! ☺
Answer: chemistry question??
Explanation:
Displacement reaction
Because Al goes to SO4 and
Cu goes from SO4 to Cu
This happens because Al is more reactive (higher up in the reactivity series) than Cu
As sulfur-31 has 16 protons (equivalent to the atomic number) in total. The quantity of protons and electrons in an atom is equal. Consequently, sulfur-31 has 16 electrons in total.
As a result, sulfur-31 has (31-16) or 15 neutrons (the difference between the mass number and atomic number).
What is the atomic number?
The average mass of an element's atoms expressed in atomic mass units is known as its atomic mass (amu, also known as daltons, D).
- The mass of each isotope is multiplied by its abundance to produce the atomic mass, which is a weighted average of all the isotopes of that element.
- (Atomic mass is also known as atomic weight however, "mass" is a more precise phrase.)
The atomic mass of an element, measured in AMU, is equal to the mass in grams of one mole of an element.
- This relationship between the atomic mass and the mole concept is important in chemistry.
Hence, the answer is 15neutrons.
