A dehydration reaction (or condensation reaction) is the process in which water molecules are produced as a polymer is formed from monomers.
A chemical reaction is the process by which substances called reactants are transformed to another substance known as products through the breaking up or building up of bonds between the reactants.
There are different types of chemicals reaction which includes condensation reaction.
Condensation reaction involves the combination of two smaller molecules known as monomers to for one larger molecule known as polymer with the loss of water molecule.
Condensation reaction is specifically called dehydration reaction due to the loss of water molecule that is involved.
Therefore, a dehydration reaction (or condensation reaction) is the process in which water molecules are produced as a polymer is formed from monomers.

11. Jack placed his new birthday helium balloon into the freezer. Will the balloon expand or shrink?
Describe what would happen to the helium gas particles. Be sure to include information about the gas
particle movement, volume (space between particles), and pressure.
Answer:
The balloon will shrink bcuz the average kinetic energy of the helium gas particles in the balloon decreases when the temp decreases. This makes the molecules move more slowly and have less frequent and weaker collisions with the inside wall of the balloon. The pressure will also decrease bcuz air pressure is the total force per unit area

Through _
plants move enormous quantities
of water from soil to air .
Explanation:
The water eventually is released to the atmosphere as vapor via the plant's stomata — tiny, closeable, pore-like structures on the surfaces of leaves. Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapor by leaves is known as transpiration
Through transpiration, plants move enormous quantities of water from the soil to the air.
Transpiration is the process by which plants lose water vapor through small openings called stomata in their leaves. Water is taken up by the roots from the soil and transported to the leaves through the xylem vessels. Once in the leaves, water evaporates from the surface of the cells and exits through the stomata into the surrounding air.
This continuous loss of water through transpiration creates a pulling force, known as the transpiration pull or tension, which helps to draw water upward from the roots. As water molecules evaporate from the leaves, more water is pulled up through the plant's vascular system to replace the lost water.
Transpiration not only aids in the transport of water and nutrients from the roots to the rest of the plant, but it also plays a crucial role in regulating the plant's temperature, maintaining cell turgidity, and facilitating the movement of minerals within the plant.

What volume is indicated on each of the graduated cylinders below? The unit of volume is mL. Make sure to check the units of graduation to get the most accurate reading possible
Answer:
Explanation: The total volume (rock plus water) in the graduated cylinder is 34 mL. We know the volume of water in the cylinder was 20 mL. Therefore, the volume of the rock must be 14 mL. Because a milliliter is exactly the same volume as a cubic centimeter, the volume of the rock is 14 cm3.
Explanation:
Image result for The unit of volume is mL. Make sure to check the units of graduation to get the most accurate reading possible
Graduated cylinders have numbers on the side that help you determine the volume. Volume is measured in units called liters or fractions of liters called milliliters (ml).

How to convert 104 Km to M
Answer:
m=104000
Explanation:
by 1km=1000m
104km=?
Now
104km=104×1000m
=104000m
Therefore,m=104000 ans
104 kilometers is equal to 104,000 meters.
A conversion factor is a ratio that shows how two different units of measurement relate to each other. You can convert a value from one unit to another by multiplying or dividing the original value by a conversion factor.
For example,
Since there are 1000 meters in a kilometer, we need to multiply the distance in kilometers by 1000 to convert it into meters.
So, to convert 104 kilometers to meters:
104 Km * 1000 = 104,000 meters
Therefore, 104 kilometers is equal to 104,000 meters.

How much energy is required to heat 2kg of ice from -5°c to 0°c
Explanation:
total heat = Heat required to convert 2 kg of ice to 2 kg of water at 0 °C + Heat required to convert 2 kg of water at 0 °C to 2 kg of water at 20 °C.
Heat=mhfg+mCpΔT
Here, m ( mass of ice) = 2 kg
hfg (latent heat of fusion of ice) = 334 KJ
Cp of water (specific heat) = 4.187 KJ/Kg-K
ΔT(Temperature difference) = 20 °C
Therefore, Heat required = 2 x 334 + 2 x 4.187 x (20 - 0 )
Heat reqd= 835.48 KJ
Therefore, to melt 2 kg of ice 835.48 KJ of heat is required.
