1) Number of moles of product, carbon dioxide, is the same as that of vinegar. So the most efficient reaction is the one with the less amount of baking soda. So RXN 1 is the most efficient.
2) Number of moles of product, carbon dioxide, is the same as that of vinegar; except RXN 5. There is an error in the number of moles of carbon dioxide. It should be 0.05034.

Answer:
3) Density multiplied by volume
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
So by rearranging this formula mass can be determine.
d = m/v
m = d×/v
Unit of mass when volume in mL and ddensity is g/mL
m = g/mL×mL
m = g
Example:
density = 5g/mL
volume = 3 mL
mass = ?
m = d×v
m = 5g/mL ×3 mL
m = 15 g
A food chain contains a producer and 3 consumers. Primary Consumers (East producers) the arrows in a food chain show the flow of energy, from the sun or hydrothermal vent your a top predator.
Answer:
Collid
Explanation:
Toothpaste is a colloid, because it's part solid and part liquid. ... A colloid is a heterogeneous mixture of two substances of different phases. Shaving cream and other foams are gas dispersed in liquid. Jello, toothpaste, and other gels are liquid dispersed in solid.
