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.

Answer: The type of compound involves the transfer of electrons is called the ionic compounds.

Explanation: ionic compounds are compounds in which one atom or molecule completely transfers an electron to another.

Ions that have gained an electron are negatively charged and they are called anions while ions that have lost an electron are positively charged and they are called cations.

If the glasses and glove were wrong then I would chose the fire extinguisher and the power source should be the correct answer.

That's just what I would do though.

The molecular mass of methyl ethanoate is 75.1 amu . calculate the molecular mass of propanoic acid, an isomer of methyl ethanoa

iren [92.7K]

Molecular Formula of Propanoic Acid is....

C₃H₆O₂
Where;

Atomic Mass of C = 12

Atomic Mass of H = 1

Atomic Mass of O = 6

Substituting Atomic Masses in molecular formula,

(12)₃ + (1)₆ + (16)₂

36 + 6 + 32

74 g/mol

Result:
Molecular Mass of Propanoic Acid is 74 g/mol. Structure of Methyl Ethanoate and Propanoic Acid are as follow,

At what temperature (in C) will a sample of gas occupy 91.3 L if it occupies 45.0 L at 70.0°C? Assume constant pressure.)

sdas [7]

Solution is here,

for initial case,

temperature(T1)=70°C=70+ 273=343K

vloume( V1) =45 L

for final case,

temperature( T2)=?

volume(V2)= 91.3 L

at constant pressure,

V1/V2 = T1/T2

or, 45/91.3 = 343/ T2

or, T2= (343×91.3)/45

or, T2=695.9 K = (695.9-273)°C=422.9°C

How many moles of Cu(OH)2 are soluble in 1L of sodium hydroxide (NaOH) when the pH is 8.23?

Morgarella [4.7K]

Answer:

4.96E-8 moles of Cu(OH)2

Explanation:

Kps es the constant referring to how much a substance can be dissolved in water. Using Kps, it is possible to know the concentration of weak electrolytes. Then, pKps is the minus logarithm of Kps.

Now, we know that sodium hydroxide (NaOH) is a strong electrolyte, who is completely dissolved in water. Therefore the pH depends only on OH concentration originating from NaOH. Let us to figure out how much is that OH concentration.

$pH= -log[H]\\pH= -log (\frac{kw}{[OH]})$
