before we begin, let's first establish an understanding of basic terminology. it may be harder than you think to clearly define

what is a chemical versus a chemical reaction. to help us better differentiate between closely related terms, review the words listed here. sort each of the words into the three categories: contains chemicals, chemical reaction, or neither.

Contains chemical : vitamin  b12, oranges, grapes, protein

chemical reaction is : neutralization, combustion, bleaching, photosyntheis

Neither : sunlight, rainbow, heat.

  • chemical is a substance
  • Chemical reaction is a rocess during which chemical bonds between atoms are broken and new ones are formed. Producing one or more different substances.
  • reactant is a starting materials in a chemical reaction
  • product is new substances that are formed in a chemical reaction
  • chemical equation is representation of a chemical reaction that uses symbols to show the relationship between the reactants and the products.
  • combustion reaction is a chemical reaction that occurs when a substance reacts with oxygen, releasing energy in the form of heat and light

Calculate the mass of the precipitate formed when 2.27 L of 0.0820 M Ba(OH)2 are mixed with 3.06 L of 0.0664 M Na2SO4.
kicyunya [14]
We are given with two reactants :barium hydroxide and sodium sulfate. The products of the reaction via double replacement is barium sulfate and sodium hydroxide. according to the solubility rules the product barium sulfate is insoluble. There is a one to one correspondence to every compound. In this case, we just have to find the limiting reactant and base the calculations there. The mass of the precipitate formed is 0.186 grams BaSO4

Calculate the amount of heat water absorbs from a piece of hot metal using the following data: 75.0 g of cold water is placed in
AysviL [449]

Answer:

Amount of heat absorbed by water is 2604.54 J.

Explanation:

Amount of heat absorbed by water = m_{water}\times C_{water}\times \Delta T_{water}

where m represents mass, C represents specific heat and \Delta T represents change in temperature.

Here m_{water}=75.0 g , C_{water}=4.184J/(g.^{0}\textrm{C}) and \Delta T = (final temperature - initial temperature) = (29.5-21.2) ^{0}\textrm{C} = 8.3 ^{0}\textrm{C}

So, amount of heat heat absorbed by water

     = (75.0g)\times (4.184\frac{J}{g.^{0}\textrm{C}})\times (8.3^{0}\textrm{C})

     = 2604.54 J

Which of the following chemical equations proves that the law of conservation of mass is in effect?
bogdanovich [222]

Answer:

2KCl + F₂   →     2KF + Cl₂

Explanation:

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

This law was given by French chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

2KCl + F₂   →     2KF + Cl₂

In this equation mass of reactant and product is equal. There are 2 potassium 2 chlorine and fluorine atoms on both side of equation it means mass remain conserved.

All other options are incorrect because mass is not conserved.

Mg₂ + LiBr ---> LiMg + Br

In this equation mass of magnesium is more on reactant side.

Na +O₂ ---> Na₂O

In this equation there is more oxygen and less sodium on reactant side while there is more sodium and less oxygen on product side.

H₂O ---> H₂ + O₂

In this equation there is less oxygen on reactant side while more oxygen on product side.

1) When elements combine to form compounds:
vodomira [7]

Answer:

B

Explanation:

when elements reacts to form a compound the elements properties changes completely. This happens due to the fact that a chemical reaction has taken place. In a chemical change new substances are formed and the properties of the products differ entirely from that of the reactant.

for example if hydrogen combines with oxygen to form water, the property of hydrogen differs from oxygen and also both differs chemically when compared to water.
