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

A small rock lies on a slope near a tropical sea. What are three ways that the rock could be eroded?
vlabodo [156]

Answer: - The heat of the sun could break down the rock.

- Tall, powerful waves could carry the rock into the ocean.

- The rock could react to seawater, break down, and be carried away by the sea.

Erosion is a natural phenomena in which the top surface of the soil or the rock  is displaced or carried away to different location. It disturbs the fertility of the soil. The physical agents responsible for erosion are water, wind, heat and others.

The three ways the small rock that lies on a slope near a tropical sea could be eroded are:

The heat of the sun could break down the rock: The sunlight incident on the rock can weak the external structure of the rock and the loosen particles are displaced by either wind and water.

Tall, powerful waves could carry the rock into the ocean: The waves can displaced the rocks away from actual place causing erosion.

The rock could react to seawater, break down, and be carried away by the sea: The sea water can bring chemical change in the rock structure and will enhance it's weathering.

How many moles of oxygen are produced when 5.12 moles of magnesium chlorate decomposes into magnesium chloride and oxygen?
goldenfox [79]
The  moles   of  oxygen  produced  is  calculated  as    follows

write  a  balanced  reacting  equation,  that  is

Mg(ClO3)2  ---->MgCl2  +  3O2

from  the  equation  above  the  reacting  ratio  of  Mg(ClO3)2  to  O2  is  1:   3  therefore  the  moles  of  O2  produced  =  5.12  moles  x3  =15.36  moles

Korvikt [17]

Answer:

nomenclature of alkanes

Explination:

Substituent Formula Number of C Atoms Name of Substituent

CH3                                   1                                         methyl–

CH3CH2                                  2                              ethyl–

CH3CH2CH2                           3                    propyl–

CH3CH2CH2CH2                       4               butyl–

CH3CH2CH2CH2CH2                     5                  pentyl–

and so forth                      and so forth     and so forth

Try this it helped me allot,

Alkenes and alkynes are named in a similar fashion. The biggest difference is that when identifying the longest carbon chain, it must contain the C–C double or triple bond. Furthermore, when numbering the main chain, the double or triple bond gets the lowest possible number. This means that there may be longer or higher-numbered substituents than would be allowed if the molecule were an alkane. For example, this molecule is 2,4-dimethylhept-3-ene (note the number and the hyphens that indicate the position of the double bond).

2,4-dimethylhept-3-ene

or two one carbonsubstituents on the second and third C atoms

its not 3-methylheptane.
