A cracker which contains starch,is test positive with iodine solution but not Benedict's solution. This is because Benedict's solution is used to test for reducing sugars like glucose,galactose,fructose,maltose and lactose.In this case, the cracker is added with amylase enzyme which hydolyses starch into maltose,thus benedict's solution is test positive

Write a balanced chemical equation based on the following description:
kupik [55]

The balanced chemical equation for the reaction is

<h3>6Cs(s) + 2CsNO₂(s) —> 4Cs₂O(s) +  N₂(g) </h3>

From the question given above, we were told that:

solid cesium reacts with solid cesium nitrite to form solid cesium oxide and nitrogen gas.

The equation for the reaction can be written as follow:

Caesium => Cs

Caesium nitrite => CsNO₂

cesium oxide => Cs₂O

nitrogen gas => N₂

Caesium + Caesium nitrite —> Caesium oxide + Nitrogen gas

<h3>Cs + CsNO₂ —> Cs₂O +  N₂</h3>

The above equation can be balance as follow:

Cs + CsNO₂ —> Cs₂O +  N₂

There are 2 atoms of N on the right side and 1 atom on the left side. It can be balance by writing 2 before CsNO₂ as shown below:

Cs + 2CsNO₂ —> Cs₂O +  N₂

There are 2 atoms of Cs on the right side and a total 3 atoms on the left side. It can be balance by writing 6 before Cs and 4 before Cs₂O as shown below:

6Cs(s) + 2CsNO₂(s) —> 4Cs₂O(s) +  N₂(g)

Now the equation is balanced

maksim [4K]

Answer:-

b. compound b will show an nh absorption while compound a will not.

Explanation:-

For compound B CH3CH2CH2NH2 there are two N-H bonds present. So it will show NH absorption.

But in compound A CH3CH2CH2N(CH3)2 there are no N-H bonds. So it will not show NH absorption.
