Hydrogen peroxide is a powerful oxidizing agent; it is used in concentrated solution in rocket fuel and in dilute solution in ha
Anestetic [448]

The molarity of the hydrogen peroxide solution from the information supplied in the question is 12.26 M.

Co = 10pd/M

Where;

Co = concentration = ?

p = percent of the hydrogen peroxide =  30%

d = Density of hydrogen peroxide =  1.39 g/ml

M = Molar mass  = 34 g/mol

Substituting values;

Co = 10 × 30 ×  1.39/34

Co = 12.26 M

The molarity of the hydrogen peroxide solution from the information supplied in the question is 12.26 M.

Is C2H7 ionic or covalent? <br><br> what would you name NO4? <br><br> what would you name MgCl2?
Vlad [161]

C₂H₇ is a covalent compound

N0₄ will be name nitrogen(viii) oxide

MgCl₂ will be named magnesium chloride.

<h3>What are covalent compounds? </h3>

Covalent compounds are compounds which are formed when two electronegative atoms combine together by a sharing of electrons between them.

Covalent compound molecules are usually formed from a combination of non-metals.

The C₂H₇ is a covalent radical formed from the addition of a hydrogen ions to the covalent compound C₂H₆

<h3>What would you name NO₄?</h3>

The name given to a compound depends on the oxidation number of the component elements.

The oxidation number of oxygen is -2.

Since there are 4 atoms of oxygen, the total negative charge is -8.

Nitrogen will have to exist in the +8 state in order to give a neutral compounds.

Therefore, the name given to the compound will be nitrogen (viii) oxide.

<h3>What would you name MgCl₂? </h3>

Magnesium chloride, MgCl₂  is an ionic compound formed from the ionic bond between chlorine and magnesium.

Magnesium donates two electrons to two chlorine atoms to form magnesium chloride, MgCl₂.

How much heat is needed to raise the temperature of water with mass of 27.0 g at 20.0°C to 45.0°C?
ohaa [14]

Answer:

2835 J

Explanation:

Take the specific heat capacity of water as 4.2 J/ g°C.

Energy (heat) = mass x specific heat capacity x change in temperature

(E= mcΔT)

E = 27 x 4.2 x (45-20)

E = 2835 J

How is proper science validated?
STatiana [176]

The proper science is validated by Experimentation and Testing .

What is experiment and testing?

Experiment is performed to support or Refuge a hypothesis which is given by someone.

Test is to figure out what we expect and what we have observed.

So , the proper validation of science is Experiment and testing because science is all about hypothesis, discoveries if want to prove them right or wrong we have to perform experiment and test .
