Answer:

Explanation:

A cyclic event is one that happens repeatedly.

The appearance of Hailey's Comet is a cyclic event because it has happened in various occasions in the past on a regular schedule as predicted. We have every reason to believe that the appearance of Hailey's Comet every 75 years will continue to be happen until the comet ceases to exist.

The combustion of ethane (C2H6)(C2H6) produces carbon dioxide and steam. 2C2H6(g)+7O2(g)⟶4CO2(g)+6H2O(g) 2C2H6(g)+7O2(g)⟶4CO2(g)

Vera_Pavlovna [14]

Answer:

11.9 moles of carbon-dioxide will produced.

Explanation:

Given moles of ethane = 5.95 mol

$2C_2H_6(g)+7O_2(g)\rightarrow 4CO_2(g)+6H_2O(g)$

According to reaction 2 moles of ethane produces 4 moles of carbon-dioxide.

Then, 5.95 moles of ethane will produce:

$\frac{4}{2}\times 5.95 mol=11.9 mol$ of carbon-dioxide

11.9 moles of carbon-dioxide will produced.

Aly's science class was looking at bacteria through a microscope. Aly's teacher said some bacteria can be as small as 0.00365 cm

olga nikolaevna [1]

Answer:

$0.00365\ cm=3.65\times 10^{-3}\ cm$

Explanation:

Aly's teacher said some bacteria can be as small as 0.00365 cm long.

In this problem, we need to write the length of the bacteria written in scientific notation. Any number can be written in the form of scientific notation as follows :

$N=a\times 10^b$

a is a real no and b is an integer

In the given number, there are two zeroes before 3. We need to shift the decimal after 3. It can be done as follows :

$0.00365\ cm=3.65\times 10^{-3}\ cm$

Hence, this is the required solution.
