Co2 is made of carbon ( atomic mass: 12) and oxygen (atomic mass : 16)
First : mass of 1 C atom + mass of 2 O atom = 12+(16*2)=44 amu so 1 mole CO2 =44 grams then 2.5 mole CO2 =44*2.5 =110 grams
So the answer is 110 grams
Malleability and ductility is present in substances in which the layers of atoms or molecules can slide over one another easily without fracturing.
Answer:
mass is 4.57 g
Explanation:
Ca(OH)₂ solution consists of Ca(OH)₂ solute molecules and solvent and we are asked to find the mass of Ca(OH)₂ in the solution
number of moles of Ca(OH)₂ is - 0.0787 mol
molar mass of Ca(OH)₂ is - 58.093 g/mol
we can use the following equation
number of moles = mass of Ca(OH)₂ / molar mass of Ca(OH)₂
rearranging the equation
mass of Ca(OH)₂ = number of moles x molar mass
mass = 0.0787 mol x 58.093 g/mol = 4.57 g
mass of Ca(OH)₂ is 4.57 g
Answer:
Hydrogen Bond
Explanation:
Hydrogen bond interactions are formed between the hydrogen atom bonded to most electronegative atoms (i.e. F, O and N) of one molecule and most electronegative atom (i.e. F, O and N) of another molecule.
In this interaction the hydrogen atom has partial positive charge and electronegative atom has partial negative charge.
Answer:
HCl + NH₃ → NH₄⁺ + Cl⁻
Explanation:
When a strong acid as HCl reacts with a weak base as NH₃ a salt that comes from the conjugate acid, NH₄⁺, and the ion of the acid, Cl⁻, is produced as follows:
<h3>
HCl + NH₃ → NH₄⁺ + Cl⁻</h3>
<em>This is the acid- base reaction</em>
The base captures the proton of the acid (proton aceptor) and the acid give the proton (Proton donor)
