Answer:
No.
Explanation:
Photosynthesis is the light dependent process which must occur for the plant to live. This process also requires water and carbon dioxide. If photosynthesis does not occur, the plant will die.
If plants do not receive enough water from the water cycle, photosynthesis can be affected, and in severe cases, it may not take place at all.
Why photosynthesis requires water?Photosynthesis requires water as one of its essential inputs, as it is used in the process of creating glucose and oxygen from carbon dioxide and light energy. Therefore, if plants do not receive enough water from the water cycle, photosynthesis can be impacted, and in severe cases, it may not take place at all.
Water is not only a raw material in photosynthesis, but it is also necessary for the regulation of plant cells' internal pressure, which is essential for maintaining their shape and structure. Without enough water, the cells' internal pressure decreases, causing them to shrink and lose their rigidity. This process is known as wilting.
Hence, water is essential for plant growth and photosynthesis, and if plants do not receive enough water from the water cycle, it can lead to wilting, stunted growth, and a reduction in photosynthesis.

What will happen if the pressure of the system is raised to 1.5 atmospheres and the temperature remains same?
The piston will move upwards because the number of moles of the gas particles will increase.
The piston will move downwards because the gas particles will occupy less volume than before.
The piston will move upwards because the gas particles will hit the walls of the container with increased force.
The piston will move downwards because the gas particles will start moving randomly in all directions, pulling the piston down.
Answer:
The piston will move downwards because the gas particles will occupy less volume than before.
Explanation:
Referring to Boyle's Law at constant temperature, the pressure P of a gas varies inversely with its volume V
PV = K
P = [tex]\frac{K}{V}[/tex]
P ∝ [tex]\frac{1}{V}[/tex]
What's the number of atoms in one mole of Magnesium?
Answer:
he mass in grams of one mole of substance is called molar mass. Each element has its own unique molar mass. For example, carbons molar mass is 12.011 g/mol, and magnesium's molar mass is 24.3050 g/mol. To see why these elements have different molar masses, we need to remember that the atoms of different elements contain different numbers of protons, neutrons, and electrons, so they have different masses. The atomic masses given in the periodic table inside the front cover of this book represent the different weighted average masses of the naturally occurring atoms of each element. Different atomic masses lead to different molar masses.
For example, the atomic mass of magnesium (24.3050) shows us that the average mass of magnesium atoms is about twice the average mass of carbon atoms (12.011), so the mass of 6.022 x 1023 magnesium atoms (the number of atoms in 1 mole of magnesium) is about twice the mass of 6.022 x 1023 carbon atoms (the number of atoms in 1 mole of carbon). Thus the molar mass of magnesium is 24.3050 g/mol, compared to carbons molar mass of 12.011 g/mol.
Explanation:
If 4.27 grams of sucrose, C12H22O11, are dissolved in 15.2 grams of water, what will be the boiling point of the resulting solution?
The elevation in temperature of water by the addition 4.27 g of sucrose to 15.2 grams is 0.42 °C. Thus the boiling point changes from 100 to 100.42 °C.
What is boiling point?Boiling point of a substance is the temperature at which the pressure of gas above the liquid phase equals the atmospheric pressure where conversion of liquid to solid takes places.
By the addition of a non-volatile solid to the solution, the boiling point increases and the increase in boiling point ΔT is proportional to the molality of the solution.
ΔT = Kb m
Where, Kb is called the ebullioscopy constant. Kb for water is 0.52 K Kg/mol.
Molar mass of sucrose = 342 g/mol
no.of moles in 4.27 grams = 4.27 /342 = 0.0124.
mass of solvent = 15.2 = 0.0015 Kg.
Molality = no/ of moles of solute/ mass of solvent in kg
= 0.015 Kg ×0.0124 mol
= 0.82 mol/Kg.
Now, the increase in temperature ΔT = 0.82 mol/Kg × 0.52 K Kg/mol.
= 0.42 °C
Thus, the new boiling point will be 100 + 0.42 °C = 100.42 °C.

Hydrogen gas and nitrogen gas come together to form ammonia. If 25.0 g of nitrogen is mixed with hydrogen, what volume of hydrogen is needed to complete the reaction? (grams to volume)
Answer:
60.0L of hydrogen are needed
Explanation:
Based on the reaction:
3H₂ + N₂ ⇄ 2NH₃
3 moles of hydrogen react 1 mole of nitrogen.
To solve this question we have to find the moles of nitrogen. With the moles of nitrogen we can find the moles of hydrogen. Using PV = nRT at STP conditions we can find the volume as follows:
Moles Nitrogen -Molar mass: 28g/mol-
25.0g N₂ * (1mol / 28g) = 0.893 moles N₂
Moles hydrogen:
0.893 moles N₂ * (3mol H₂ / 1mol N₂) = 2.679 moles H₂
Volume hydrogen:
PV = nRT
V = nRT / P
Where V is volume in liters,
n are moles of the gas: 2.679 moles
R is gas constant: 0.082atmL/molK
T is absolute temperature: 273.15K at STP
P is 1atm at STP
Replacing:
V = 2.679mol*0.082atmL/molK*273.15K / 1atm
V =
60.0L of hydrogen are needed

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.

A sample of air starts at STP. The volume and moles remains the same, what happens to the pressure if the temperature changes to 317 K?
show steps
Answer:
Pressure increases to 1.16 atm if the temperature changes to 317 K.
Explanation:
The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C (or 273 K) are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.
On the other hand, Gay Lussac's law indicates that when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases. This law mathematically indicates that the quotient between pressure and temperature is constant:
[tex]\frac{P}{T}=k[/tex]
Studying an initial state 1 and a final state 2 is fulfilled:
[tex]\frac{P1}{T1}=\frac{P2}{T2}[/tex]
In this case:
P1= 1 atmT1= 0 C= 273 KP2= ?T2= 317 KReplacing:
[tex]\frac{1 atm}{273 K} =\frac{P2}{317 K}[/tex]
Solving:
[tex]P2=317 K*\frac{1 atm}{273 K}[/tex]
P2= 1.16 atm
Pressure increases to 1.16 atm if the temperature changes to 317 K.
