Answer:

650 grams

Explanation:

Given that acetylene gas reacts with oxygen to produce caobon dioxide, water and heat and the unbalnced equation is

C_2H_2(g)+O_2(g) \rightarrow CO_2(g) + H_2O(g)+ heat

Gram-formula mass of C_2H_2= 26 g/mol

So, mass of 1 mole of acelylene is 26 grams

Therefore, mass of 25 moles of acelylene=25x26=650 grams

Hence, the mass of 25 moles of acelylene is 650 grams

When compounds form, what is one result for the atoms that bonded?
Montano1993 [528]

When compounds form, the atoms that bonded get a stable arrangement of electrons.

Compounds form because their atoms get a more stable arrangement than they had in the reactants.

A stable arrangement is a <em>complete octet</em> of eight electrons in the valence shell .

For the following SN2 reaction, draw the organic and inorganic products of the reaction, and identify the nucleophile, substrate
Sauron [17]

Answer:

Substrate:alkyl halide

Leaving group: Cl

Organic product: The nitrile

Inorganic product: Cl-

Nucleophile: CN-

Explanation:

An SN2 reaction is a concerted bimolecular reaction. Concerted means that it involves two reactions taking place at the same time while bimolecular means that the rate determining step involves two molecules. The cyanide ion attacks the alkyl halide from the rear. In the transition state, the leaving group (Cl-) is departing while the nucleophile (CN-) is forming a bond to the alkyl halide simultaneously. The alkyl halide is the substrate in the reaction. The organic product is the nitrile shown in the image attached.
