The dependent variable is plant height.

The <em>dependent variable</em> (plant height) is the <em>property that changes</em> as a result something the scientist does.

The <em>independent variable</em> is the <em>property that the scientist changes</em> systematically (the amount of CO_2) to see its effect.

The <em>number of plants</em> and the <em>types of plants</em> are <em>uncontrolled variables</em>. They may or may not affect the heights of the plants.

14. Convert 4084 grams of NH3 kept at -40°C to Liters at STP. The density as a liquid is
Zigmanuir [339]

The density of the gas can be given by the mass of the substance and its volume. A 4084 gms of ammonia has a volume of 5.99 L.

<h3>What is STP?</h3>

STP is the condition at which the temperature and the pressure of the gas are at the normal and standard conditions.

The density of the ammonia = 681.9gm/L

The mass = 4084 gm

The volume is calculated as:

V = Mass ÷ Volume

= 4084 ÷ 681.9

= 5.99 L

Therefore, at STP the volume of ammonia is 5.99 L.

In a water molecule (H2O), the oxygen atom has two unshared pairs of electrons and two bonding pairs of electrons. How do the un
vladimir1956 [14]

Answer:

They reduce the bond angle to be slightly lower than the tetrahedral bond angle, approximately 104.45 degrees.

Explanation:

The unshared pair of electrons or lone pair electrons in order to have the minimum repulsion possible with each other pushes the other bonding pairs closer together making the bond angle smaller or bent.

The bond angle is slightly lower than the tetrahedral bond angle of 108 degrees, leaving the water molecule with a bent molecular geometry.
