Answer:
It would be half an half because it depends on the plant and location
Explanation:
It would be half an half because it depends on the plant and location.
What are Plants?The kingdom Plantae contains eukaryotes that are mostly photosynthetic.
Algae and fungi were once included in the plant kingdom, which historically included all living creatures that were not animals; however, all modern definitions of Plantae omit these organisms along with some algae and prokaryotes (the archaea and bacteria).
Green algae and Embryophyta are included in the concept of plants as belonging to the clade Viridiplantae (Latin for "green plants"), which is sister to the Glaucophyta (land plants).
Therefore, It would be half an half because it depends on the plant and location.

Can a molecular formula ever be the same as an empirical formula? Explain your answer.
Answer:
The molecular formula for a compound can be the same as or a multiple of the compound's empirical formula. Molecular formulas are compact and easy to communicate; however, they lack the information about bonding and atomic arrangement that is provided in a structural formula.

Answer:
His name is Harold
Explanation:
In describing weather completely, it is important to include, among other aspects, air pressure, precipitation, and humidity. Which of the following statements is false?
Wind is the movement of air that results from differences in air pressure.
Precipitation is a form of water that falls to Earth’s surface from the clouds.
Air typically moves from areas of lower pressure to areas of higher pressure.
When the temperature of the air cools to the dew point, the air is saturated, and water droplets will form.
Answer:
The false statement is - Air typically moves from areas of lower pressure to areas of higher pressure.
Explanation:
The wind is the air movement that takes place due to pressure differences or the temperature difference of air. Air moves from the higher pressure area to the lower pressure area. The more the difference will be the faster the air will move to a low-pressure area.
Precipitation is a form of water that falls from clouds to earth, it can be rainfall, snow and other forms. Dew is one of the forms that occur when the air cools down to the dew point and form droplets.
Answer:
Air typically moves from areas of lower pressure to areas of higher pressure.

What volume in liters will 50.0g CO occupy? please show work.
Answer:
40.0L is the volume the CO occupy
Explanation:
To solve this question we must assume the gas is at STP. To find the volume of a gas using the moles, temperature and pressure of the gas we have to use:
PV = nRT
V = nRT / P
Where V is volume in liters
n are moles of the gas -Molar mass CO: 28g/mol-
50.0g * (1mol / 28g) = 1.786 moles CO
R is gas constant = 0.082atmL/molK
T is absolute temperature = 273.15K at STP
P is pressure = 1atm at STP
Replacing:
V = 1.786moles*0.082atmL/molK*273.15K / 1atm
V = 40.0L is the volume the CO occupy
An element has the atomic number 72. The number of protons and electrons in a neutral atom of this element is
Explanation:
Hi,
The number of protons is equal to the atomic number. The number of electrons in a neutral atom is equal to the number of protons. So, in this case, you have 72 protons and 72 electrons.
I hope this helps :)
If an element has the atomic number 72, then the number of protons is also equal to 72. As it is clearly mentioned in the question that it is a neutral atom, which means the number of protons is equal to the number of electrons which is also 72.
What is meant by an Atomic number?An atomic number may be defined as the number of a chemical element in the modern periodic table through which the elements are systematically arranged in order of increasing the number of protons in the nucleus.
According to the context of this question, the atomic number of every element is always equal to the number of protons it has. While in a neutral atom, the number of electrons is equal to the number of protons. For calculating the number of neutrons, you have to subtract the atomic number from the atomic mass.
Therefore, there are 72 protons of an element whose atomic number is 72. The number of electrons is also 72.

Compare How does the horse's average speed from 60 s to 120 s compare to its average speed from 120 s to 180 s?
Answer:
Explanation:
To compare the average speed, we would need some parameters which you clearly didn't state in your question. However, permit me to manufacture some from thin air.
The formula for average speed is given as
Speed = distance / time
From the question, we have the time, but not the distance moved by the horse. Now, assuming the horse moves a distance of 60 meters, then we can say,
Speed = 60 / 60
Where the difference between the two time, t = 120 - 60 = 180 - 120 = 60
So, from my hypothesized example, the average speed of the horse is 1 m/s

How many calories of heat were added to 167.9 g of water to raise its temperature from 25oC to 55oC?
Answer:
Q = 5036.9 calories
Explanation:
Given that,
Mass, m = 167.9 g
The temperature raises from 25°C to 55°C.
The specific heat of water,c = 4.184 J/g °C
We need to find the heat added to water. We know that,
[tex]Q=mc\Delta T\\\\=167.9 \times 4.184\times (55-25)\\\\=21074.8\ J[/tex]
or
Q = 5036.9 calories
So, 5036.9 calories of heat is added.

find the ratio of the initial volume to final volume if the temperature of the gas is changed from 27°C to 127°C at constant pressure.
Answer: The ratio of the initial volume to final volume for the given gas is 27 to 127 L at constant pressure.
Explanation:
Given: [tex]T_{1} = 27^{o}C[/tex]
[tex]T_{2} = 127^{o}C[/tex]
According to Charle's law, for an ideal gas pressure is directly proportional to the temperature at constant pressure.
So, formula used to calculate the ratio of the initial volume to final volume is as follows.
[tex]\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}[/tex]
Substitute the values into above formula as follows.
[tex]\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}\\\frac{V_{1}}{V_{2}} = \frac{T_{1}}{T_{2}}\\\frac{V_{1}}{V_{2}} = \frac{27}{127}[/tex]
Hence, we can conclude that the ratio of the initial volume to final volume for the given gas is 27 to 127 L at constant pressure.
what can you infer about aspirin’s ester group?
A. It provides aspirin’s pain-killing ability.
B. It makes the compound more digestible.
C. It reduces fevers.
It's B
Answer:
Option B, aspirin’s ester group provides greater digestibility to aspirin
Explanation:
Aspirin ester group has three parts
carboxylic acid functional group (R-COOH) ester functional group (R-O-CO-R') aromatic group (benzene ring)Aspirin is a weak acid and hence it cannot dissolve in water readily. The reaction of Aspirin ester group with water is as follows -
aspirin
(acetylsalicylic acid) + water → salicylic acid + acetic acid
(ethanoic acid)
Aspirin passes through the stomach and remains unchanged until it reaches the intestine where it hydrolyses ester to form the active compound.

a gas measured a volume 100 mL under pressure of 740 mmHg. What would the volume be under a pressure of 780 mmHg with constant temperature
Answer:
94.87 mLExplanation:
The new volume can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we're finding the new volume
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
We have
[tex]V_2 = \frac{100 \times 740}{780} = \frac{74000}{780} \\ = 94.8717...[/tex]
