Answer:

The shape of the molecule will determine the direction of each of the individual bond dipoles, and thus, will always play a role in determining the polarity of the molecule as a whole.

What type of reaction is this.... CH2(g)+02(g)
oee [108]

Combustion

Explanation:

This reaction is called a combustion reaction. It is very peculiar to reactions involving hydrocarbons.

In such reactants, oxygen gas is used as a reactant. It combines with fuel usually the hydrocarbon to produce heat and light energy.

For the combustion of most hydrocarbons, water and carbon dioxides are usually the product.

        2CH₂   +   3O₂  →   2CO₂   +  2 H₂O

A 70.0-g piece of copper metal at 54.0 °C is placed in 50.0 g of water at 26.0 °C. If the final temperature of the water and met
KatRina [158]

The specific heat in, J /g °C of copper is 0.386J/g°C

HOW TO CALCULATE SPECIFIC HEAT CAPACITY OF A SUBSTANCE:

  • The specific capacity of a substance can be calculated using the following formula:

Q = m × c × ∆T

Where;

Q = quantity of heat absorbed or released (J)

m = mass of substance (g)

∆T = change in temperature (°C)

c = specific heat capacity (J/g°C)

For a colorimeter, the following equation applies:

m.c.∆T (water) = - m.c.∆T (metal)

  • For water:

m = 50g

c = 4.184 J/g°C

∆T = 29.2 - 26°C = 3.2°C

  • For copper:

m = 70g

c = ?

∆T = 29.2 - 54°C = -24.8°C

m.c.∆T (water) = - m.c.∆T (metal)

50 × 4.184 × 3.2 = -(70 × c × -24.8)

669.44 = 1736c

c = 669.44 ÷ 1736

c = 0.386J/g°C

Therefore, the specific heat in, J /g °C of copper is 0.386J/g°C

A reaction that is essentially the opposite of a synthesis reaction describes which of the following?
Afina-wow [57]

Answer is: b) decomposition.

Synthesis is reaction of two or more substances combining to make a more complex substance.

Decomposition is reaction where one substance is broken down into two or more simpler substances.

For example, balanced chemical reactio:

CaCO₃(s) → CaO(s) + CO₂(g).

Chemical decomposition is the separation of a single chemical compound (in this example calcium carbonate) into its two or more simpler compounds (in this example calcium oxide and carbon dioxide).

Combustion is reaction with oxygen.

Single Displacement is reaction where  neutral element metal or nonmetal become an ion as it replaces another ion in a compound.  

Double displacement reactions (more reactive metals displace metals with lower reactivity).
