To balance this equation, make a chart below the reaction keeping track of all atoms on both the left and right side of the reaction, and place appropriate coefficients to balance the atoms on both sides.

Balanced equation:
2HCl + Ba > BaCl2 + H2.

NEED SOME CHEM HELP
zloy xaker [14]
Hello!

The substances, ordered according to their dissolving time in water, are the following

Sugar Cubes > Granulated Sugar > Powdered Sugar

The difference between these substances is the degree of order. According to collision theory, for a substance to be dissolved, successful collisions between solvent molecules and solute molecules need to happen. as molecules are more ordered, successful collisions are less likely to happen, because atoms are fixed into a crystalline structure.

When the molecule is less ordered, successful collisions are more likely to occur, as the atoms can be impacted from different sides and aren't fixed into a given position. 

As the degree of order increases, the dissolving time in water will be higher too, as more time would be required for successful collisions to happen. The most ordered substance is sugar cubes, followed by granulated sugar and powdered sugar, and that order is the same as the order for dissolving time. 

Have a nice day!

why are the theoretical density values of brass, bronze, and steel reported as a range of densities? how can you categorize thes
Julli [10]

<u>Answer:</u>

<em>Theoretical density values  </em>

  • brass- 8.4-8.73 gm/cm^3
  • bronze- 8.73 g/cm^3
  • steel- 7.75 - 8.05 gm/cm^3

<u>Explanation:</u>

All of these substances are<em> </em>alloys (a substance made from melting two or more substances, one of them usually being a metal). Brass is a combination of copper and zinc, bronze is mostly copper, tin and other non-metals as well and steel is majorly made up of iron and copper. These alloys have various uses and varying importance in different kinds of industries.

A flask contains 5.0g of neon gas at a temperature of 35°C. The pressure gauge indicates 0.37atm inside the flask. What is the v
DaniilM [7]

Answer:

The volume of the neon gas is 17.07 L.

Explanation:

The ideal gas equation describes the relationship among the four variables  P, V, T, and n. An ideal gas<u> is a hypothetical gas whose pressure-volume-temperature  behavior can be completely accounted for by the ideal gas equation</u>.

In order to calculate the volume, first we need to convert the grams of neon to moles:

28.18 g Ne ------ 1 mol Ne

5.0 g Ne---------- <u>x= 0.25 mol Ne</u>

Now, using the ideal gas equation we calculate the volume:

pV= nRT

V= nRT ÷ p

V= (0.25 mol × 0.082 L.atm/mol.K × 308.15 K ÷ 0.37 atm

V= 17.07 L
