A defibrillator delivers about 300 joules per shock calculate the number of calories

Chemistry
1 answer:
Tanya [424]2 years ago
4 0

Answer:- 71.7 calories

Solution:- it is a unit conversion problem where we need to convert joules into calories.

The unit conversion for these energy units is:

1 calorie = 4.184 joule

The given energy is 300 joules and has to be converted to calories. We will show the set up using dimensional analysis.

300joules(\frac{1calorie}{4.184joules})

= 71.7 calories

So, the energy in calories is 71.7.

An unknown triprotic acid (H3A) is titrated with NaOH. After the titration Ka1 is determined to be 0.0013 and Ka2 is determined
e-lub [12.9K]

Answer:

6.68 X 10^-11

Explanation:

From the second Ka, you can calculate pKa = -log (Ka2) = 6.187

The pH at the second equivalence point (8.181) will be the average of pKa2  and pKa3. So,

8.181 = (6.187 + pKa3) / 2

Solving gives pKa3 = 10.175, and Ka3 = 10^-pKa3 = 6.68 X 10^-11

The substances sodium (Na), oxygen (O2), and sodium oxide (Na2O) participate in this chemical reaction:
Andrews [41]

The chemical reaction involving sodium and oxygen as given in the reaction: 4Na + O2 → 2Na2O is a synthesis reaction.

<h3>What are chemical reactions?</h3>

Chemical reactions are changes which occur in the chemical composition of atoms of substances which results in the formation of new substances.

There are different types of chemical reactions such as:

  • synthesis reaction
  • displacement reaction
  • double displacement reactions

A synthesis reaction is a reaction in which two or more substances combine to form a new product.

Therefore, the chemical reaction involving sodium and oxygen as given in the reaction: 4Na + O2 → 2Na2O is a synthesis reaction.
