The correct Answer is A.

The Flow chart of the Carbon Cycle, will look as follows:

1. Carbon dioxide in the atmosphere.

2. Producers undergo photosynthesis (in this process plants among other producers like algae, use CO2 to produce energy).

3. Consumers eat producers (a primary level of consumer like a rabbit eats the producers or plants).

4. Decomposers return Carbon to the soil and release waste.

And the cycle continues again, by going back to step 1.

Answer:

Q1. C

Q2 and Q3 are correct.

Explanation:

Since F=ma, and the force is a constant,

for the greatest acceleration, the mass of the ball must be the least.

Thus ball C has the greatest acceleration.

Let's check:

A) F=ma

a=F/m

a= F/68

B) a=F/72

C) a= F/64 (✓)

The smaller the denominator, the larger the value of a.

(Think: 1/2 >1/3)

Which one of the following represents an acceptable set of quantum numbers for an electron in an atom? (arranged as n, l, ml, an

vfiekz [6]

First, since l = n-1,
5,4,-5,1/2 and 2,1,0,1/2 are the only answer choices left.
Next, since ml = -l to l,
2,1,0,1/2
is the answer because in 5,4,-5,1/2, the ml value of -5 is not in the range of -4 to 4, as notes by the value 4 for l.

Balance the equation and show the calculation of the number of moles and grams of CO2 formed from 11.9 grams of O2. Show your an

n200080 [17]

Answer:

0.2349 moles, 10.3356 g

Explanation:

The given reaction is :

$C_6H_{14}+O_2\rightarrow CO_2 + H_2O$

The balanced reaction by equating the same number of each atom both side is :

$2C_6H_{14}+19O_2\rightarrow 12CO_2 + 14H_2O$

Given that :

Amount of oxygen gas = 11.9 g

Molar mass of oxygen gas = 32 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus, moles are:

$moles= \frac{11.9\ g}{32\ g/mol}$

$moles= 0.3719\ mol$

From the reaction,

19 moles of oxygen gas on reaction forms 12 moles of carbon dioxide

Also,

1 mole of oxygen gas on reaction forms 12/19 moles of carbon dioxide

So,

0.3719 moles of zinc on reaction forms $\frac {12}{19}\times 0.3719$ mole of carbon dioxide

Moles of carbon dioxide formed = 0.2349 moles

Mass of carbon dioxide = moles×Molar mass

Molar mass of carbon dioxide = 44 g/mol

Mass of carbon dioxide formed = 0.2349 ×44 g = 10.3356 g
