Answer:
An electric force is exerted between any two charged objects. Objects with the same charge, both positive and both negative, will repel each other, and objects with opposite charges, one positive and one negative, will attract each other.
Explanation:
Answer:
1.83moles
Explanation:
Given parameters:
Mass of methane given = 29.2g
Unknown:
Number of moles = ?
Solution:
To find the number of moles in this mass of a compound;
Number of moles =
Molar mass of CH₄ = 12 + 4(1) = 16g/mol
Now;
Number of moles =
= 1.83moles
Explanation:
As density is defined as the mass of a substance divided by its volume.
Mathematically, Density = 
It is given that mass is 50 g and density is 0.934
.
Hence, calculate the volume of methyl acetate as follows.
Density = 
0.934
= 
Volume = 
or, =
(as 1
= 1 mL)
Thus, we can conclude that the volume of methyl acetate the student should pour out is
.
