If o100 ml of 3. zero m solution were diluted to 250 ml awareness of<u> 1.2 M.</u>

The concentration of the solution tells you how tons solute has been dissolved within the solvent. for example, in case you upload one teaspoon to two cups of water, the awareness could be stated as 1 t salt in keeping with 2 c water.

V1 = one hundred mL, M1  = 3 M

V2 = 250 mL, M2 = ?

observe Dilution regulation

M1*V1 = M2*V2

so

M2 = M1*V1/V2

M2 = 100/250*3

M2 = 1.2 M

Concentration (normally uncountable, plural concentrations) The act, procedure, or capability of concentrating; the system of becoming focused, or the country of being concentrated. The course of interest to a particular object. The act, technique or product of reducing the quantity of a liquid,

What is the process called to prepare a ceramic by heating a slurry of a powder of an inorganic substance in water to a very hig
Zolol [24]

<u>Answer:</u> The process that is used to prepare ceramic is sintering.

<u>Explanation:</u>

Sintering is defined as the process in which number of particles are fused together to form one solid mass by the applying pressure at high temperatures.

Ceramic is an material that is made by taking mixtures of clay, earthen elements, powders and water.

When this mixture (slurry of the powders) is heated at a very high temperature and under high pressure, ceramic is formed.

Hence, the process that is used to prepare ceramic is sintering.

how many grams of molecular oxygen (O2) is produced from 13.8 grams of calcium chlorate (Ca(ClO3)2)in the following chemical rea
olga2289 [7]

Answer:

6.72 g

Explanation:

Given data:

Mass of calcium chlorate = 13.8 g

Mass of oxygen produced = ?

Solution:

Chemical equation:

Ca(ClO₃)₂        →      CaCl₂ + 3O₂

Number of moles of calcium chlorate:

Number of moles = mass / molar mass

Number of moles = 13.8 g/ 206.98 g/mol

Number of moles = 0.07 mol

Now we will compare the moles of oxygen and  calcium chlorate.

                 Ca(ClO₃)₂         :            O₂

                      1                   :              3

                    0.07               :            3×0.07=0.21 mol

Mass of oxygen:

Mass = number of moles × molar mass

Mass = 0.21 mol × 32 g/mol

Mass = 6.72 g

What type of compound involves the transfer of electrons?
astra-53 [7]

Answer: Electrovalent or Ionic Compounds

Explanation:

Electrovalent Compounds Form bonds that are characterised by transfer of electrons from metallic atoms to non-metal licenses atoms during a chemical reaction.

The metallic atom after donating their valence electrons, become positively charged, while the non-metal license atoms becomes negatively charged after acquiring extra electrons.

A typical example of electrovalent compounds can be found between the association of Group 1(Alkali Metals) elements and the Group 7(Halogen Family) elements.
