What is the mass of silver bromide that precipitates when 2.96 g of iron(iii) bromide is combined with excess silver nitrate?

1 answer:

7 0

5.6400 is the mass of silver bromide that precipitates when 2.96 g of iron(iii) bromide is combined with excess silver nitrate.

<h3>Difference between silver bromide and iron(iii) bromide</h3>

Silver bromide (AgBr) is a soft, pale-yellow, water-insoluble salt well known (along with other silver halides) for its unusual sensitivity to light. This property has allowed silver halides to become the basis of modern photographic materials. AgBr is widely used in photographic films and is believed by some to have been used for making the Shroud of Turin. The salt can be found naturally as the mineral bromargyrite.

Iron(III) bromide is the chemical compound with the formula FeBr3. Also known as ferric bromide, this red-brown odourless compound is used as a Lewis acid catalyst in the halogenation of aromatic compounds. It dissolves in water to give acidic solutions.

When does long-term carbon cycling occur? Select all that apply.

aev [14]

Answer:

The long-term carbon cycle is the main controller of the concentration of atmospheric carbon dioxide and (along with the sulphur cycle) atmospheric oxygen over a geological timescale1,2. It can be represented succinctly by the generalized reactions3,4: Figure 1: A model of the long-term carbon cycle

A.When the animals die, they decompose, and their remains become sediment, trapping the stored carbon in layers that eventually turn into rock or minerals. Some of this sediment might form fossil fuels, such as coal, oil, or natural gas, which release carbon back into the atmosphere when the fuel is burned.

B.Cells use oxygen to "burn" food for energy. Water and carbon dioxide are produced as wastes. The cells in both plants and animals perform respiration. Carbon dioxide is also released into the atmosphere when fuels are burned, such as in automobiles or factories

c.During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose

d.Fossil fuels are made from decomposing plants and animals. These fuels are found in the Earth's crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil, and natural gas are examples of fossil fuels.

Hydrogen peroxide rapidly decomposes to water and oxygen. If the water is appearing at a rate of 2.0 M/s, what is the rate of th

balu736 [363]

Answer:

Rate of reaction = 2.0 M/s

Explanation:

2H2O2(g) --> 2H2O(g) + O2(g)

Rate of formation of H2O = 2.0 M/s

Rate of reaction can be measured using multiple techiques and parameters like volume, pressure etc.

Among these techniques is the measurement of appearance of products.

This means we have;

Rate of reaction = Rate of appearance of product

Hence;

Rate of reaction = 2.0 M/s
