Limescale removers contain sulfamic acid, H3NSO3, which reacts with minerals in hard water

I am Lyosha [343]

Answer:

0.375 moles of CaCO₃ are required

Explanation:

Given data:

Number of moles of sulfamic acid = 0.75 mol

Number of moles of calcium carbonate required = ?

Solution:

Chemical equation:

2H₃NSO₃ + CaCO₃ → Ca(SO₃NH₂)₂ + CO₂ + H₂O

Now we will compare the moles of H₃NSO₃ and CaCO₃ .

H₃NSO₃ : CaCO₃

2 : 1

0.75 : 1/2×0.75 = 0.375 mol

Thus, 0.375 moles of CaCO₃ are required.

Draw Lewis structures for the fluoroethene molecule (C2H3F), the acetonitrile molecule (CH3CN), and the acetylene molecule (C2H2

vagabundo [1.1K]

Answer:

Please check image and explanation

Explanation:

Lewis structure means drawing all the lone pair and bond pair around the atom and also lone pair of electron is represented as pair of dot except in the odd electron system where electron is denoted by only one dot. single bond is denoted by single line and similarly double bond denoted by two parallel line and so on

generally less electronegative atom is taken as central atom or atom having more covalency.
