Answers

Answer 1

Answer:

Answer:

Atomic models have similarities and differences

Explanation:

Is this molecule a polar or non polar?

Answers

Answer:

This is polar

Explanation:

Cuantas moléculas de oxigeno se producen por la descomposición de 28.5 g de H2O2 (masa molecular = 34.0g/mol) de acuerdo a la ecuación 2H2O2(l) → 2H2O(l)+O2(g)

Answers

The question is as follows: How many oxygen molecules are produced by the decomposition of 28.5 g of H2O2 (molecular mass = 34.0g / mol) according to the equation

2H2O2 (l) → 2H2O (l) + O2 (g)

Answer: There are $2.52 * 10^(23)$ molecules are produced by the decomposition of 28.5 g of $H_(2)O_(2)$ according to the equation $2H_(2)O(l) \rightarrow 2H_(2)O(l) + O_(2)(g)$ .

Explanation:

Given: Mass of $H_(2)O_(2)$ = 28.5 g

As moles is the mass of a substance divided by its molar mass. Hence, moles of $H_(2)O_(2)$ is calculated as follow.

$Moles = (mass)/(molarmass)\n= (28.5 g)/(34.0 g/mol)\n= 0.838 mol$

According to the given equation, 2 moles of $H_(2)O_(2)$ gives 1 mole of $O_(2)$ . So, moles of $O_(2)$ produced by 0.838 moles of $H_(2)O_(2)$ will be calculated as follows.

$Moles of O_(2) = (0.838 mol)/(2)\n= 0.419 mol$

This means that moles of $O_(2)$ produced is 0.419 mol.

As per the mole concept, 1 mole of every substance has $6.022 * 10^(23)$ molecules.

So, molecules of $O_(2)$ present in 0.419 mole are as follows.

$0.419 * 6.022 * 10^(23)\n= 2.52 * 10^(23)$

Thus, we can conclude that there are $2.52 * 10^(23)$ molecules are produced by the decomposition of 28.5 g of $H_(2)O_(2)$ according to the equation $2H_(2)O(l) \rightarrow 2H_(2)O(l) + O_(2)(g)$ .

Which of the following is a major consequence of the shifting of the Intertropical Convergence Zone (ITCZ)? A. monsoon rains in South Asia B. few winds in the horse latitudes C. jet streams over the North Atlantic D. lush vegetation in the Amazonian rainforest

Answers

The shifting of the Intertropical Convergence Zone (ITCZ) results to A. monsoon rains in South Asia. The ITCZ is a region on Earth where the Northern and Southern hemispheres meet, causing the trade winds from both regions to meet. This causes a belt of low pressure, making the region prone to heavy rainfall or monsoon rains.

Which of the following is a secondary pollutant?A) sulfur dioxide
B) radon
C) carbon monoxide
D) sulfuric acid

Answers

Final answer:

A secondary pollutant is one that is not directly emitted but rather forms when primary pollutants react in the atmosphere. Among the options provided, sulfuric acid is a secondary pollutant. Correct option is D.

Explanation:

In the context of environmental science, a secondary pollutant is a type of pollutant that is not directly emitted. Instead, secondary pollutants are formed when primary pollutants undergo chemical reactions in the atmosphere. Among the options provided, option D) sulfuric acid is a secondary pollutant. The others - sulfur dioxide, radon and carbon monoxide - are primary pollutants, as they're emitted in this form from a source.
