How is black oxide converted into red oxide​

Chemistry
1 answer:
Cloud [144]3 years ago
4 0

Answer:

The usual way of converting black oxide to red oxide involves treating the black oxide with sulphuric acid and then roasting the intermediate product thus formed. lt is known that the amount of acid can be considerably less than the stoichiometric amount needed to convert all the black oxide to a sulphate.

Hope it helps :9

Which instrument is most often used to measure acid volume before a titration begins?
Darya [45]

<span>Good Morning!
 
To measure the volume of an acid we use in the laboratory an instrument called burette (a). This instrument is used to calculate the volumes of chemical solutions. At first glance, these tools may be confused with syringes, but have different functions.

Match each of the following descriptions to thecorrect element listed
Slav-nsk [51]

Answer: Please see explanation for answer

Explanation:Matching the  descriptions to the correct element listed gives

Element Group Name Group No Metal/ Nonmetal/ Metalloid Description

Neon    Noble gases       18           Non metal Colorless, tasteless, and        odorless gas, unreactive, nonconductive.

Bromine      Halogens   17          Non metal Not found as a free element (uncombined) in nature, reddish-brown liquid that vaporizes readily at room temperature to a red gas with a strong disagreeable odor.

Beryllium       Alklaline earth metal  2    Metal  Silvery-white, ductile, malleable, conductive solid with a high melting point for this type of element

Platinum     Platimum group metals  10   Metal      Silvery white, relatively soft, low density, conductive solid that is not found as a free element in nature but commonly found combined in alloys with copper or nickel

Potassium   Alkali Metals   1   Metal  Soft, easily cut with a knife to expose a silvery surface that rapidly oxidizes in air; never found uncombined in nature

Silicon    Carbon family     1`4  Metalloid   Metallic luster and grayish solid, very common in rocks and gemstones such as amethyst and opal, semiconductor

Sulfur   Calcogens      16  Non metal  Pale yellow, odorless, brittle solid at room temperature, nonconductor

Which statement is most consistent with the plum pudding model of the atom?
lianna [129]
The answer to this question would be: <span>1) Electrons occupy regions of space
</span><span>
In plum pudding model, the atoms are drawn as pudding and the negative particle is spread around the pudding. In this model, the electron is spread but not moving in orbit. Rutherford model that comes afterward is the one that says most of the atoms is empty space.</span>

A metal bulb is filled with 10.2 g of CHCl3 and 0.322 g of CH4 (two gases). What is the total pressure in the bulb if the temper
vovikov84 [41]

Answer:

3. 107 atm

Explanation:

First, we will calculate the moles of each gas by dividing its mass by its molar mass.

nCHCl₃ = 10.2 g/(119.38 g/mol) = 0.0854 mol

nCH₄ = 0.322 g/(16.04 g/mol) = 0.0201 mol

The total number of moles is 0.0854 mol + 0.0201 mol = 0.1055 mol.

The absolute temperature is 345°C + 273.15 = 618 K

We can find the pressure of the gaseous mixture using the ideal gas equation.

P × V = n × R × T

P = n × R × T / V

P = 0.1055 mol × 0.08206 atm.L/mol.K × 618 K / 0.0500 L

P = 107 atm
