Chemical equations show how chemicals interact when a reaction occurs. They use symbols and formulas to show the chemical reaction so that chemical names do not need to be written out. They also help keep track of all elements and the number of atoms of each element on each side of the equation.
Oh jk haha LOL bye hahaha
Answer:
D
Explanation:
The atomic number of hydrogen is 1, because hydrogen is considered the number #1 element in the periodic table. Hope this helps!
Answer:
<em>Both charges are of the same sign (positive or negative) and with a value of 3.73 ηc.</em>
Explanation:
<u>Coulomb's Law</u>
The electrical force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between the two objects.
Written as a formula:
Where:
q1, q2 = the objects' charge
d= The distance between the objects
We know both charges are identical, i.e. q1=q2=q. Since the force is repulsive, both charges are positive or negative.
We also are given the force between them:
And also the distance
d=25 cm = 0.25 m
Substituting all into the formula:
The product of . Operating:
Operating:
Solving for q:
Both charges are of the same sign (positive or negative) and with a value of 3.73 ηc.
