Calcium Carbonate is very cheap to produce in bulk and has some properties that can be favorable for building a house.  That being said, im guessing you got this question from the acid rain post with calcium carbonate.  Many things will break down in contact with an acidic substance but it will take a very long time in the case of acid rain (because it is dilute)

Because it is used for building - making concrete and cement - and the manufacture of glass, steel and iron.

Annette [7]

Answer: Zn(s)+CuSO_4(aq)\rightarrow ZnSO_4+Cu

Explanation:-

Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.

As zinc is more reactive than copper, it could easily displace copper from its aqueous solution and thus leads to formation of zinc (II) sulfate and pure copper.

The chemical reaction can be represented as :

Zn(s)+CuSO_4(aq)\rightarrow ZnSO_4+Cu

The phases are represented as (s) for solid sate, (l) for liquid state, (g) for gaseous state and (aq) for aqueous state.

Calculate the total mass of the protons and electrons in 19 9F. Use 1.007825 amu as the mass of 11H (mass of a proton and an ele
SVETLANKA909090 [29]

Explanation:

Atomic mass means the sum of total number of protons and neutrons present in an atom.

When an atom is neutral then number of protons equal the number of electrons.

Mass of a proton equals to 1.007276 u, mass of neutron equals to 1.008664 u.

For example, in a ^{19}_{9}F atom there are total 9 protons and number of neutrons is 19 - 9 = 10.

Since, it is a neutral atom so number of electrons will also be 9.

So, total mass will be calculated as follows.

                  Total mass = 9 (mass of electron + mass of proton)

                                      = 9 (1.007825 u)

                                      = 9.07043 u

Therefore, we can conclude that total mass of protons and electrons in ^{19}_{9}F is  9.07043 u.
