Why do we use conversion factors instead of just multiplying or dividing as needed? What’s the advantage?

If you’re referring to stoichiometry, which usually involves the long t-tables of multiple conversions, then you’re not alone in wondering the purpose of using them. The purpose of conversion tables is to help keep track of what you’re doing. When quickly converting one value to another, it’s very easy to forget a particular piece to the puzzle, or to use a factor that doesn’t work for that instance. Teachers usually draw out a t-table every time they work a problem so as not to confuse students, but anytime you’re working with funky units or converting across systems (metric to imperial and vice versa) it’s a good idea to use them.

45. What is the H ion concentration of an aqueous solution
Vinvika [58]

Answer:

= 1 X 10⁻⁻¹²M

Explanation:

At 25°C & 1atm [H⁺][OH⁻] = 1 x 10⁻¹⁴ => [H⁺] = 1 X 10⁻¹⁴/[OH⁻] = 1 X 10⁻¹⁴/1 X 10⁻²

= 1 X 10⁻⁻¹²M

A cup of gold colored metal beads was measured to have a mass 425 grams. By water displacement, the volume of the beads was calc
Butoxors [25]
If the volume of 425 grams was 48.0 cm³, simply divide

g/cm³ = 425 g/48 cm³ = 8.85 g/cm³

If using water in water displacement, 1 mL = 1 cm³

8.85 g/cm³ = 8.85 g/mL

This density is most closely aligned with that of B. Copper

If an object has two forces acting on it how can the next force equal 0
Flura [38]

If the forces are equal and in opposite directions, the net force will equal zero.

Consider a tug-of-war team. If they are pulling with equal forces against each other, the red cloth on the rope will not move.

<em>F = ma </em>

The cloth is not moving, so <em>a = </em>0 and the net force <em>F = </em>0.
