Chemistry
1 answer:
Reil [10]2 years ago
8 0

Answer:

Double replacement or double decomposition

Explanation:

In the reaction below, a double replacement or double decomposition has occurred.

     

          2Na₃PO₄   +   3CaCl₂   →  6NaCl  +  Ca₃(PO₄)₂

This reaction occurs mainly between two ionic substances.

The reaction involves an actual exchange of partners to form new compounds. For example;

             AB  + CD →  AD + CB

One of the following conditions below serves as the driving force for double replacement reactions:

  • Formation of an insoluble compound or precipitate.
  • Formation of water or any other non-ionizing compound
  • Liberation of a gaseous product.

If the caffeine concentration in a particular brand of soda is 3.55 mg/oz, drinking how many cans of soda would be lethal? Assum
monitta

Answer:

The answer to your question is: 234.7 cans

Explanation:

data

caffeine concentration = 3.55 mg/oz

10.0 g of caffeine is lethal

there are 12 oz of caffeine in a can

Then

                    3.55 mg ----------------- 1 oz

                      x    mg  -----------------12 oz (in a can)

x = 42.6 mg of caffeine in a can

Convert it to grams 42,6 mg = 0.0426 g of caffeine in a can

Finally

            0.0426 g of caffeine ------------------  1 can

            10           g of caffeine -----------------    x

x = 10 x 1/0.0436 = 234.7 cans

If the half-life of hydrogen-3 is 11.8 years, after two half-lives the radioactivity of a sample will be reduced to one-half of
maw [93]

Answer:

False

Explanation:

Half life is the time period at which the concentration of the radioactive substance in decay reduced to half.

<u>Thus, if the hydrogen-3 has gone 2 half lives, it means that it has first reduced to its half and then again the half of what it was, i.e. 1/4</u>

Thus, after two successive half-lives, the concentration must be 1/4 of the initial concentration and hence, the statement is false.
