Answer: A new substance is created through the transformation of reactants into products.

Explanation:

A chemical reaction is a process that leads to the transformation of substances through the creation or destruction of chemical bonds between atoms, and this involves changes in energy. Reactions in which energy is released are exothermic reactions, while those that take in heat energy are endothermic. During a chemical reaction, the atoms can share electrons (and this creates bonds) or they can gain or lose electrons (creating ions)

The substance involved is called reactant, and the result substance is called product, which may have different properties from the reactants. When two ore more reactants contact each other, the bonds in the reactants are broken, and atoms are rearrange to form new bonds to make the products. So, a new substance is created through the transformation of reactants into products. No new atoms are created, and no atoms are destroyed.

Chemical reactions happen at a characteristic reaction rate at a given temperature and chemical concentration. Typically, reaction rates increase with increasing temperature because there is more thermal energy available to reach the activation energy necessary for breaking bonds between atoms.

Reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products. Hope this helps!

Nikitich [7]

Answer:

Explanation:For example, you are in a bus and it goes with the velocity of 50 m/s to the east, then a truck passes you with a velocity of 60m/s to the east. ... Velocity of the moving objects with respect to other moving or stationary object is called “relative velocity” and this motion is called “relative motion”

If the freezing point of a soda is – 4.5 ºC and you leave it in your car overnight when the temperature dips to 25 ºF, will the

Sveta_85 [38]

Explanation:

We leave a soda in the car overnight and the temperature dips to 25 °F. To see if it will freeze we have to convert the °F to °C.

T(°C) = ( T(°F) - 32 ) *5/9

T(°C) = (25 - 32) *5/9

T(°C) = -3.9 °C

Since -3.9 °C is a temperature greater than the freezing point (-4.5 °C) the soda won't freeze.

Answer: The soda won't freeze.

A chemical reaction has two elements as reactants. Which type of reaction might occur?

Marrrta [24]

Chemical changes are a result of chemical reactions. All chemical reactions involve a change in substances and a change in energy. Neither matter or energy is created or destroyed in a chemical reaction---only changed. There are so many chemical reactions that it is helpful to classify them into 4 general types which include the following:SYNTHESIS REACTION
In a synthesis reaction two or more simple substances combine to form a more complex substance. Two or more reactants yielding one product is another way to identify a synthesis reaction.
For example, simple hydrogen gas combined with simple oxygen gas can produce a more complex substance-----water!
The chemical equation for this synthesis reaction looks like:

reactant + reactant -------> product
To visualize a synthesis reaction look at the following cartoo
In the cartoon, the skinny bird (reactant) and the worm (reactant) combine to make one product, a fat bird.
 DECOMPOSITION REACTION
In a decomposition reaction a more complex substance breaks down into its more simple parts. One reactant yields 2 or more products. Basically, synthesis and decomposition reactions are opposites.
For example, water can be broken down into hydrogen gas and oxygen gas. The chemical equation for this decomposition reaction looks like:

reactant -------> product + product
To visualize a decomposition reaction look at the following cartoon:In this cartoon the egg (the reactant), which contained the turtle at one time, now has opened and the turtle (product) and egg shell (product) are now two separate substances.SINGLE REPLACEMENT REACTION
In a single replacement reaction a single uncombined element replaces another in a compound. Two reactants yield two products. For example when zinc combines with hydrochloric acid, the zinc replaces hydrogen. The chemical equation for this single replacement reaction looks like:

reactant + reactant ---------> product + product
To visualize a single replacement reaction look at the following cartoon:

Notice, the guy in the orange shirt steals the date of the other guy. So, a part of one of the reactants trades places and is in a different place among the products.DOUBLE REPLACEMENT REACTION
In a double replacement reaction parts of two compounds switch places to form two new compounds. Two reactants yield two products. For example when silver nitrate combines with sodium chloride, two new compounds--silver chloride and sodium nitrate are formed because the sodium and silver switched places. The chemical equation for this double replacement reaction looks like:

reactant + reactant ---------> product + product
To visualize a double replacement reaction look at the following cartoon:
