Answer:
6 mols
Explanation:
Notice that on the left, there is one "O2" molecule, and one O2 results in two "H2O" molecules. So the ratio of O2 to H2O is 1 to 2
If we have 3 mols of oxygen, then per the ratio, we would have 6 mols of H2O, since 3*2=6
Answer:
Jimmy wrote two expressions that are not equivalent
Explanation:
24+6=30 while 6(4+2) equals 36 because if you distribute the 6 to 4 (which equals 24) then the 6 to 2 (which equals 12) and add 24 and 12 together, you get 36. So, 24+6 =/= 6(4+2). Hopefully this is correct!
Answer:
the mass of a planet doesn't matter, considering many
planets are made up of gas, and how in different situations,
atmospheres can be destroyed (The Sun burnt off Mercury's
Atmosphere). However, in some cases, the planet can be in a good
situation on the galaxic map, and have great conditions for an
atmosphere, such as Earth. In which case, the mass of an object can
attract a smaller object, causing gravity. Therefore, the bigger
the mass of a planet when in right and specific conditions, the
more atmosphere it can attract, if there is any floating by the
planet.
If it is bigger it will have more gravitational influence and
therefore gather more gases.

Answer:
C. Corrosive waste
Explanation:
Hydrochloric acid is formed when hydrogen chloride gas is dissolved in water. The gas is toxic when inhaled and dissolves very readily in water to form the acid.
Hydrochloric acid is a strong acid as it ionizes completely in aqueous solutions to produce chloride ions and hydronium ions.
The concentrated acid is very corrosive in that it dissolves many other substances. Therefore, great care must be taken when handling the concentrated form of the acid.
It poses an environmental hazard due to its corrosive nature. Also, in industries and science laboratories, concentrated hydrochloric acid can corrode metal pipes and should not be drained into pipes without first being diluted.
However, the acid is very important in many industrial as well as laboratory procedures.
Answer:
Explanation:
Hello,
In this case, given the reaction:
We notice a 3:1 molar ratio between sodium hydroxide and phosphoric acid, therefore, at the equivalence point we have:
That in terms of molarity is:
Se we solve for the volume of acid:
Best regards.
