Basically, since buildings are made from limestone, acids react with the limestone in the building, breaking it down continually to form salt thereby causing in the destruction of the building.ie
CaCO3 + H2SO4
--> CaSO4 + H2CO3
H2CO3 --> CO2 gas + H2O
Mass is the measure of the quantity of the substance present in the sample containing a compound or molecule. The mass of sucrose in the sample is 171 g.
<h3>What is mass?</h3>
The mass of the compound in the sample is the product of the number of moles of the substance and the molar mass of the compound.
Given,
The molar mass of the sucrose compound = 342.3 g/mol
Number of moles of sucrose = 0.500 moles
Mass of sucrose is calculated as:
Therefore, option A. 171 gm is the mass of sucrose.

Answer:
Only the oxygen needs to be balanced. There are equal numbers of hydrogen and carbon
Explanation:
Given expression:
C₂H₄ + O₂ → 2H₂O + 2CO₂
The law of conservation of mass suggests that chemical equations be balanced since atoms are neither created nor destroyed in the course of a chemical reaction. In retrospect, bonds are broken and chemical species are change to another form.
From the given equation, only oxygen is not balanced. This flouts the law of conservation.
On the reactant side, we have 2 oxygen on the product, we have 6.
Answer:
Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position). A moving car possesses mechanical energy due to its motion (kinetic energy).
Explanation:
The temperature that the balloon will expand to 3.50 l is 463.56 K
<em><u> calculation</u></em>
by use of Charles law formula
that is V1/T1 = V2/T2 where;
V1 = 2.25 l
T1= 298 k
V2= 3.50 l
T2=?
make T2 the subject of the formula T2 =(V2 xT1) /v1
T2= (3.50 l x 298 K) /2.25 L = 463.56 K
