There would be no day and night :(
Answer:
C
Explanation:
Spontaneous combustion is a type of combustion which occurs by self-heating (increase in temperature due to exothermic internal reactions), followed by thermal runaway (self-heating which rapidly accelerates to high temperatures) and finally, ignition.
El Niño = the boy, La Niña = the girl. You can tell from the ending and the first word.
Answer:
3.05 g
Explanation:
The reaction that takes place is:
As the decomposition not necessarily was complete we'll work with the<em> given mass of product formed</em>. We convert <u>the 12 grams of chlorine to moles</u>, using its <em>molar mass</em>:
- 12 g ÷ 70.906 g/mol = 0.169 mol
Then we <u>convert Cl₂ moles to H₂O moles</u>:
- 0.169 mol Cl₂ *
= 0.169 mol H₂O
Finally we <u>convert moles to grams</u>:
- 0.169 mol H₂O * 18 g/mol = 3.05 g
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.
