Answer:
1.566x10²⁴ atoms of Cl
Explanation:
In Carbon tetrachloride, CCl₄, you have 4 moles of Cl per mole of CCl₄. To solve this question we must find the moles of CCl₄ in order to find the moles of Cl. Using Avogadro's number we can solve the chlorine atoms:
<em>Moles CCl₄: 153.82g/mol</em>
100g * (1mol / 153.82g) = 0.65 moles CCl₄
<em>Moles Cl:</em>
0.65 moles CCl₄ * (4 moles Cl / 1mol CCl₄) = 2.6 moles Cl
<em>Atoms Cl:</em>
2.6 moles Cl * (6.022x10²³ atoms / mol) =
<h3>1.566x10²⁴ atoms of Cl</h3>
The surface area is a big help
Answer:
It is a force acting on the object.
Explanation:
The answer option which is true about the weight of an object is: C. It is a force acting on the object.
Weight can be defined as the force acting on a physical body or an object as a result of gravity. Also, the weight of an object is measured in Newton.
Mathematically, the weight of an object is given by the formula;
Where;
m is the mass of the object.
g is the acceleration due to gravity.
In conclusion, the weight of an object is the force acting on an object due to gravity.
Answer:
The amount of thermal energy stored in an object depends on three things.
- The mass of the object.
- The temperature of the object.
- The amount of energy that the particular material stores per degree of temperature.
