the coefficients are equal is NOT a sign that a double displacement reaction has occurred
<u>Explanation:</u>
Usually during solutions of two ionic compounds are combined a precipitate (solid) is created. The mix may become cloudy, or may also separate, with the solids falling at the seat of the receptacle. Infrequently, the mix may bubble as a gas or water is produced.
A precipitation reaction is at two aqueous ionic compounds that make a unique ionic compound that is not soluble in water. The insoluble product compound is called the precipitate. The reaction, in this case, is not balanced, which are evaluated by summing coefficients.
Answer:
wind can cause rocks to erode and can expose more of the earth crust then before.
Answer:
The answer would most likely be C 22 grams.
Explanation:
I did a small science experiment when I was in high school with mold and it did increase the weight of whatever food I was using but not that significant so I think it would be 22 grams.
1. Density is calculated by dividing the object's mass by the volume it occupies.
2. The volume may be determined by water displacement method.
3. D = m/v
Substituting the known values,
D = 10.0 g / 15.625 cm³ = 0.64 g/cm³
