Explanation:
The electrical force between two objects is given by the formula as follows :
k is electrostatic constant
q₁ and q₂ are electric charges
d is distance between charges
So, the two force between two charged objects depends on the product of charges and distance between charges.
Answer:
2.73%
Explanation:
Molarity of NaOH = 0.75 M
Density of solution = 1.1 g/mL
Mass percent of NaOH = ?
Solution:
Number of moles of NaOH = 0.75 mol from 0.75 mol/L
Mass of NaOH = number of moles × molar mass
Mass of NaOH = 0.75 mol × 40 g/mol
Mass of NaOH = 30 g
Mass of solution:
d = m/v
1.1 g/ mL = m/ 1000 mL
m = 1100 g
Percentage of NaOH:
% NaOH = mass of solute / mass of solution × 100
% NaOH = 30 g/ 1100 g × 100
% NaOH = 2.73%
Ionic bonds are a class of chemical bonds that result from the exchange of one or more valence electrons from one atom, typically a metal, to another, typically a nonmetal. This electron exchange results in an electrostatic attraction between the two atoms called an ionic bond.
So I would think A
Answer:
[1] P4 + [3] O2=[2] P2O3
Explanation:
you can first solve for amount of O2 in the equation because reactant had O2 and product had O3, so the amount of O2 should be 3 and amount of O3 should be 2, which gets u to 6 moles of oxygen for both reactant and product. then you can balance the P4, and 1 mols of P4 = 2 moles of P2, which matches with the amount of mols for O3 as well. therefore you can get P4 + 3O2 = 2P2O3
Pentyl ethanoate is a carbon compound known as ester. When an ester reacts with water, it is known as a hydrolysis reaction. During hydrolysis, pentyl ethanoate (ester) will dissociate in to a carboxylic acid and an alcohol. In this case, the pentyl ethanoate will dissociate into ethanoic acid and pentanol.
