At the beginning of the school year, a chalk company receives an order for 2000 boxes which is the largest order ever placed. Ea
lys-0071 [83]

Answer:

  • <u>259,000 g of chalk.</u>

Explanation:

<u>1) Data:</u>

a) 2000 boxes

b) 175 g / box

c) % yield = 74%

<u>2) Formula: </u>

  • % yield = (theoretical yield / actual yield) × 100

<u>3) Solution:</u>

a) Calcualte the actual yield:

  • mass of product = 2000 box × 175 g/ box = 350,000 g

b) Solve for the theoretical yield from the % yield formula:

  • % yield = (theoretical yield / actual yield) × 100

        ⇒ theoretical yield = % yield × actual yield / 100

             theoretical yield = 74% × 350,000g / 100 = 259,000 g

Given the reaction: H2O2(l) ⇌ H2(g) + O2(g) The forward reaction is endothermic. Determine which of the following changes would
Vlad [161]

Answer:

I and IV

Explanation:

Increasing the number of particles at one side of the reaction (H2 in this case) results in the shifting of the equilibrium to the side with lesser number of particles, so in this case the equilibrium will shift to the left (towards the reactants)

A decrease in temperature will always function to favor the exothermic reaction, and since the backwards reaction is exothermic, the equilibrium will shift to the left (towards the reactants).

Option II and V will shift the equilibrium to the products, and adding a catalyst has no effect on the equilibrium.

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming
yanalaym [24]

This would support Dalton's postulates that says atoms are indivisible because there are no smaller particles than the atoms.

Explanation:

If during Thomson's cathode rays experiment, the size of the particles produced is the same as the size of the atom forming the cathode, it would perfect corroborate with Dalton's postulate.

  • John Dalton believed the simplest substance of any matter is an atom.
  • An atom is indivisible and cannot be broken down.
  • From his atomic theory, matter does not any other smaller particles besides atom.
  • If the size of the atoms of rays and that of the cathode were to be the same, this would have supported his claim.

Arranges the following molecules in order of increasing dipole moment: <br> H2O, H2S, H2Te, H2Se.
erastova [34]

Explanation:

Dipole moment is defined as the measurement of the separation of two opposite electrical charges.

H_{2}O is a bent shaped molecule with a dipole moment of 1.87.

H_{2}S is also a bent shaped molecule with a dipole moment of 1.10.

H_{2}Te is a also a bent shaped molecule and has a negligible dipole moment.

H_{2}Se has a dipole moment of 0.29.

Therefore, given molecules are arranged according to their increasing dipole moment as follows.

        H_{2}Te < H_{2}Se < H_{2}S < H_{2}O
