The temperature that water boils on the fahrenheit scale is c. 212°f.

<h3>What is Temperature conversation?</h3>

Temperature conversation is a way of converting a temperature from a unit to another using conversation scale.

Therefore, on fahrenheit scale water boils at  212°f which is equivalent to 100°C on the Celcius scale.

Which statement is always true about a reversible chemical reaction?
Alecsey [184]
<h2>Answer:</h2>

Option (B):

The products can form reactants, and the reactants can form products.

<h3>Explanation:</h3><h3>Reversible reaction</h3>

A reversible reaction is a reaction where the reactants form products, which react together to give the reactants back.

aA + bB ⇄ cC + dD

A and B can react to form C and D or, in the reverse reaction, C and D can react to form A and B.

Other options are wrong because off:

(A) Concentration changes with time equilibrium concentration and higher product concentration is also possible.

(C) They may be constant.

(D) Concentration changes with time equilibrium concentration and higher reactant concentration is also possible.

scientific description about the pizza dough doubles its size when it is placed in a warm place . how does this happen
Marina CMI [18]
Answer is: because carbon(IV) oxide is released.
For example if baking soda is used for <span>the pizza dough, than on heat carbon(IV) oxide is product of chemical reaction:
2NaHCO</span>₃ → Na₂CO₃ + CO₂ + H₂O.
If we use yeast (<span>single-celled microorganism)</span>, also carbon(IV) oxide produced, because yeast turns sugars into carbon(IV) oxide.

From the list below, choose which groups are part of the periodic table. metals acids flammable gases nonmetals semimetals ores
iris [78.8K]

The periodic table of the elements are describe the electronic configuration of the elements on which the properties of the elements depends. Among the given groups only metal, non-metal and semi-metal group are the part of periodic table. The metallic property depends upon the binding energy of the electrons with the nucleus. Thus the elements which have the valence electrons more near to the nucleus that is s-block elements are more metallic in nature. On the other hand the elements which have the valence electrons far from the nucleus are more non-metallic in nature like p-block elements. However the binding energy or the attraction of the outermost electrons to the nucleus depends not only its valence electrons position but also some other factors like shielding effect, effective nuclear charge etc.

The elements which are in between the metals and non-metals can be classified as semi-metals.

Although the conductivity of a material is an inherent property of the metals but sometime the nonmetals or semi-metals are also behave like a conductor due to presence of the other elements, thus it cannot be a p[property of the periodic table. Similarly acidity, flammable gases are not part of the periodic table.

Given the standard heats of reaction
ANTONII [103]

Answer:

Explanation:

M(s) → M (g ) + 20.1 kJ --- ( 1 )

X₂ ( g ) → 2X (g ) + 327.3 kJ ---- ( 2 )

M( s) + 2 X₂(g) → M X₄ (g ) - 98.7 kJ ----- ( 3 )

( 3 ) - 2 x ( 2 ) - ( 1 )

M( s) + 2 X₂(g) - 2 X₂ ( g ) - M(s)  → M X₄ (g ) - 98.7 kJ -  2 [ 2X (g ) + 327.3 kJ ] - M (g ) - 20.1 kJ

0 = M X₄ (g ) - 4 X (g ) - M (g ) - 773.4 kJ

4 X (g ) +  M (g ) =  M X₄ (g ) - 773.4kJ

heat of formation of M X₄ (g ) is - 773.4 kJ

Bond energy of one M - X bond =  773.4 / 4 =  193.4 kJ / mole
