Answer:
Carbon Dioxide = CO2
Explanation:
The synthesis of Malachite is seen in the chemical formula:
CuSO 4 . 5H2O(aq) + 2NaCO3(aq) --> CuCO 3 Cu(OH) 2 (s) + 2Na 2 SO 4 (aq) + CO 2 (g) + 9H 2 O(l)
The bubbles mentioned in the question hints that our interest is the compounds in their gseous phase (g).
Upon examining the chemical equation, only CO2 is in the gaseous state and hence the only one that can be formed as bubbles,
Answer:
pour the rock salt mixture throught a filter made from paper and allow the liquid to filtrate .
Explanation:
Separating Sand and Salt
Probably the easiest method to separate the two substances is to dissolve salt in water, pour the liquid away from the sand, and then evaporate the water to recover the salt.
<span>A. smog
B. Use a large amount of water
C. increased temperatures
D. poisoning wildlife
The correct answer is D) poising wildlife. Burning fossil fuels and pesticide from farming have the effect of releasing toxic elements in nature, thus the consequences of poisoning wildlife. The fossil fuels released CO2 and other particulates that threats the respiration system of most animals, while the pesticide that animals ingest or breath can have different effects on the wildlife, depending on the type of pesticide.

Answer:
Arrow.
Explanation:
Hello!
In this case, since chemical reactions are characterized by the presence of some species at the left on an arrow representing the reactants and at the right the products, we understand that the arrow, separating reactants and products is understood as "produces" or in very chemical words "yields"; therefore, the symbol that takes the place of the word yields is an arrow.
Best regards!
That would be an ionic bond since it has electrons to spare, rather than a convalent bond where all the electrons are taken up thus it is not a good conductor
