Answer:

There is no bar graph attached to this question, however, the question can be answered based on the information given in the question.

The answer is A) average level of happiness

Explanation:

In an experiment, the dependent variable is the variable which is measured by the experimenter. It is the variable that responds to changes made to another variable called independent variable.

In the case of this question, it can be determined, even without the bar graph, that the experiment entails how candy allowance affects a child's happiness. Hence, the candy allowance is changed to influence or cause a response in the child's happiness, which is then measured. Therefore, the AVERAGE LEVEL OF HAPPINESS is the dependent variable.

In the reduction process of photosynthesis, electrons are transported from water to carbon dioxide.

According to photon theory here the photons behave as light energy particle.
By capturing sun energy (photons), chlorophyll aids in this process.An electron in the chlorophyll molecule gets excited from a lower to a higher energy state when chlorophyll receives energy from sunlight.

Excessive sunshine is the main cause of leaves turning a darker green color. Lack of sunlight causes a plant's leaves to create more chlorophyll, which is what gives the plant its green hue.

The color of the leaf is darker green than typical because of the increase in chlorophyll concentration per unit area.

<h3>What is photon theory?</h3>

The photon theory of light states that photons have simultaneous particle and wave behavior. pass through empty space at a constant speed, or "the speed of light". possess rest energy and zero mass.

10. Airbags in automobiles contain the compound sodium azide, NaN3. A crash triggers the decomposition reaction of NaN3 to produ

Archy [21]

Answer:

The answer is 139.1 g of sodium azide.

Explanation:

To solve this question we need to find first the stoichometry of the reaction to find the moles involved.

1. The balanced formula:

2NaN3 ⇒ 3N2 + 2Na

(important: the nitrogen is a gas, therefore, is always diatomic N2)

2. The moles:

We need to convert the 90 g of N2 into moles to know the relations of amounts between the other compounds in the chemical equation

90 g of N2 x (1 mol of N2/ 28 g of N2) = 3.21 mol of N2

3. Stoichometry:

The relations of the amounts of moles of N2 and NaN3 using the balanced formula

3.21 mol of N2 x (2 mol of NaN3/3 mol of N2) = 2.14 mol of NaN3

4. Moles into grams

then to answer the question we convert the moles value of NaN3 into grams of NaN3

2.14 mol of NaN3 x ( 65 g of NaN3/ 1 mol of NaN3) = 139.1 g of NaN3.

and this is the answer of the question.
