The reduction of nitrogen monoxide is described by the following chemical equation: 2H2 (g) +2NO (g) 2H20 ()N2 (g Suppose a two-

Ipatiy [6.2K]

Answer:

Reasonable Second step- $N_{2}O(g)+H_{2}(g)\rightarrow N_{2}(g)+H_{2}O(g)$

Explanation:

The given single step chemical reaction is as follows.

$2H_{2}(g)+2NO \rightarrow 2H_{2}O(g)+N_{2}(g)$

Suppose a two-step mechanism is proposed for this reaction,

The reaction occured in two steps they are as follows.

$Step -1:H_{2}(g)+2NO \rightarrow N_{2}O(g)+H_{2}O(g)$

$Step-2:N_{2}O(g)+H_{2}(g)\rightarrow N_{2}(g)+H_{2}O(g)$

Determine the oxidation state of the metal ion in [co(nh3)5br]2+. express your answer as an integer.

Zanzabum

[Co(NH₃)₅Br]²⁺

Ligands and charges on them,

5 × NH₃ = 5 × 0 = 0

1 × Br⁻¹ = 1 × -1 = -1

Charge on sphere = +2

So, putting values in equation,

Co + (0)₅ - 1 = +2

Co + 0 - 1 = +2

Co - 1 = +2

Co = +2 + 1

Co = +3

Result:
Oxidation state of Co in [Co(NH₃)₅Br]²⁺ is +3.

10. Carbon tetrachloride has a density of 1.60 g/mL. What is the volume of 40 grams of CCl4?

ikadub [295]

Answer:

The answer is

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

$volume = \frac{mass}{density}$

From the question

mass of CCl4 = 40g

Density = 1.6 g/mL

The volume is

$volume = \frac{40}{1.6}$

We have the final answer as

Hope this helps you

An insoluble solid that forms from a chemical reaction is called a(n)

Kisachek [45]

This description applies and is suitable for what a chemical precipitate is. A precipitate is a product that is formed from a certain chemicals reaction that yields a solid that is insoluble in the reaction vessel. It is usually white and opaque.

Plss answer the question in the picture. If you actually answer I will give you brainilest!!!

DedPeter [7]

Answer:

hey :)

your answer is D.

Explanation:

To find density, you must divide mass and volume.

8 divided by 4 is 2

6 divided by 6 is 0

4 divided by 2 is 2

hope i helped any :))
