Answer:
Ca(s)+Mn2+(aq)(1M)⇌Ca2+(aq)(1M)+Mn(s)
Explanation:
Answer :
The atomic mass is the sum of the number of protons and neutrons in the nucleus of an atom.
Explanation :
Atomic number : it is defined as the number of protons or number of electrons.
Atomic number = number of protons = number of electrons
Mass number or atomic mass : It is defined as the sum of the number of protons and the number of neutrons.
Mass number or atomic mass = Number of protons + Number of neutrons
For example :
Number of protons in carbon = 6
Number of neutrons in carbon = 6
Mass number or atomic mass = Number of protons + Number of neutrons
Mass number or atomic mass = 6 + 6
Mass number or atomic mass = 12
Thus, the atomic mass is the sum of the number of protons and neutrons in the nucleus of an atom.
2. 5 acids: coffee, lemonade, soda pop, orange juice, vinegar
5bases: ammonia, baking soda, cough medicine, liquid soaps
3. Acids are very common in some of the foods we eat.
Bases have properties that mostly contrast with those acids
4. Acid+Base=H2O+Salt
HCI+NaOH=H2O+NaCI
Explanation:
2. (all those acids are strong (in pH meaning those are weak and don't affect you) (most the bases are very strong like ammonia)
4. Salt means any ionic compound formed from an acid/base reaction
Hope this helped

Answer:
Explanation:
Hello!
In this case, when writing net ionic equations, we first need to identify the complete molecular equation; thus for potassium dichromate reacting with copper (I) bromide, we have:
Thus, since all the species are aqueous except copper (II) dichromate, we can write the complete ionic equation by ionizing the aqueous ones:
Finally, for the net ionic equation, we need to cancel out the spectator ions as they are present at both reactants and products sides, thus, we obtain:
