The mass of this much chain is 0.22 grams for 7.5m of Grade 70 tow chain, which has a diameter of /38" and weighs 2.16/kgm, to tow a car.
<h3>What are weight and mass?</h3>
Mass is the amount of the substance and object and the weight is the gravitational force required to act upon the particular mass of the substance.
To calculate the mass of car divide the wight to the gravity value 9.8 meter per second.
mass = weight / gravity
substituting the value,
mass = 2.16 / 9.8
mass = 0.22 grams
Therefore,7.5m of Grade 70 tow chain, which has a diameter of /38" and weighs 2.16/kgm, to tow a car the mass will be 0.22 grams.

Answer:
The correct option is: 2.50 g
Explanation:
Reaction involved: Mg(s) + 2 HCl(aq) → MgCl₂(aq) + H₂(g)
Molar mass: Mg = 24.305 g/mol, HCl = 36.461 g/mol
In the given reaction, 1 mole Mg reacts with 2 moles HCl.
Given: mass of HCl = 7.50 g
So, the number of moles of HCl = given mass ÷ molar mass = 7.50 g ÷ 36.461 g/mol = 0.2057 moles
Therefore, the<u> number of moles of Mg</u> that reacts with 0.2057 mole HCl = 0.2057 ÷ 2 = 0.1028 moles
Therefore, <u>the mass of Mg in grams</u> = molar mass × number of moles = 24.305 g/mol × 0.1028 mole = 2.5 g
Carbon is special and unique because it is able to form different compounds with a lot of elements, including itself. When it bonds with itself, this is possible because of the concept of hybridization. It is the mixing of atomic orbitals into a new hybrid orbital. In this case, methane is formed through the sp³ hybridization.
