Answer:
Extremely large and small numbers that have many zeros are long to write and take up a lot of room. So, by using scientific notation a number can be written shorter. For example, numbers such as 295,000,000,000 can be shortened to 2.95x
. This is easier to write and understand. This is why the scientific notation is used over standard.
Answer:
C3H8 + 5O2 → 3MgO + 2NH3
Zn + 2HCl → ZnCl2 + H2
Ca(OH)2 + 2H3PO4 → Ca3(PO4)2 + 6H2O
4Al + 3O2 → 2Al2O3
Step-by-step explanation:
I have the exact same question and I got the answers correct.
<span>The probability is given as No of favourable outcomes over total number of events. Now, the no of clubs in a deck of cards is 13 and similarly, the number of jacks in a deck of cards is 13. Then, the probability that a card picked at random from a 52-card deck of playing cards is a club or a jack = 13+13/52 = 26/52 = 1/2 = 50%</span>
6 and 1/6 because 37 divided by 6 equals 6 R 1
