I believe such reactions are called decomposition reactions. Decomposition reactions are reactions that involve breaking down a compound into smaller compounds or individual elements. They involve input of energy in the form of heat, electricity or light to break down the compounds. When light is used the reaction is referred to as photo decomposition while when heat is used the reaction is thermal decomposition reaction e.t.c. The general form of the reaction is AB = A + B.

Answer:

decomposition reaction

Explanation:

The decomposition or analysis reaction (because through it can be studied the chemical elements that give rise to the decomposed substance) is one of the types of chemical reactions in which a given compound, spontaneous if unstable and stable if defragmented chemically, it gives rise to at least two different products. In other words we can define decomposition reactions as reactions where a large molecule is decomposed into the smaller parts that compose it.

What is the density of a cylinder with a mass of 65.34g, a height of 15.60 cm and a radius of 1.34 cm?
jonny [76]

Answer:

d = 0.743 g/cm³

Explanation:

Given data:

Mass of cylinder = 65.34 g

Height = 15.60 cm

Radius = 1.34 cm

Density of cylinder = ?

Solution:

Volume of cylinder:

V = πr²h   (π = 22/7)

V = 88 cm³

Density of cylinder:

d  = m/v

d = 65.34 g / 88 cm³

d = 0.743 g/cm³

Barium nitrate reacts with aqueous sodium sulfate to produce solid barium sulfate and aqueous sodium nitrate. abigail places 20.
raketka [301]
I will assume the chemical reaction equation is like this:
<span>Ba(NO3)2 + Na2SO4 ---> 2 NaNO3 + BaSO4
</span>
For every 1 barium nitrate molecule used, there will be 1 barium sulfate formed. The number of molecule barium sulfate formed would be: <span>20.00 ml * 0.500 mol/1000ml * 1= 0.01 mol

The mass of barium sulfate produced: 0.01mol * </span>233.38 g/mol= 2.3338 grams

Calculate the standard cell emf for the reaction: ClO3−(aq)+3Cu(s)+6H+(aq)→Cl−(aq)+3Cu2+(aq)+3H2O(l) Pt is used as an inert elec
Rama09 [41]

<u>Answer:</u> The standard EMF of the cell is 1.11 V

<u>Explanation:</u>

For the given chemical equation:

ClO_3^-(aq)+3Cu(s)+6H^+(aq.)\rightarrow Cl^-(aq.)+3Cu^{2+}(aq.)+3H_2O(l)

The half reaction follows:

<u>Oxidation half reaction:</u>  Cu(s)\rightarrow Cu^{2+}+2e^-;E^o_{Cu^{2+}/Cu}=0.34V    ( × 3)

<u>Reduction half reaction:</u> ClO_3^-(aq.)+6H^+(aq.)+6e^-\rightarrow Cl^-(aq.)+3H_2O(l);E^o=1.45V

To calculate the E^o_{cell} of the reaction, we use the equation:

E^o_{cell}=E^o_{cathode}-E^o_{anode}

Substance getting oxidized always act as anode and the one getting reduced always act as cathode.

Calculating the E^o_{cell} using above equation, we get:

E^o_{cell}=1.45-0.34=1.11V

Hence, the standard EMF of the cell is 1.11 V

soaps do not work well in hard waters. But they can still be effected it large quantities of soap are added to water. Explain wh
zmey [24]
The minerals in hard water react with soap and affect its cleaning capacity. It's still possible to use hard water when washing by using more soap. The additional soap will no longer be affected by the minerals in the water, so they can clean just as effectively, but you'll be wasting more soap this way.

How to prove that NaCl is homogeneous mixture.
lesantik [10]
I'm not sure if this is your question but with NaCl (salt) and water it is homogeneous because when mixed, all the salt particles are even throughout and diffuse throughout the water.
