Then explain, in a general sense, how you will determine which of the above types of reactions are occurring in your experiments.
Answers
Answer:
.
Explanation:
-Synthesis reactions are reactions that appear when two distinct atoms or molecules engage to structure a specific molecule or compound. Most of the time, when a synthesis response occurs, electricity is launched and the response is exothermic. However, an endothermic consequence is additionally possible.
-A decomposition response starts offevolved from a single substance and produces extra than one substance; that is, it decomposes. One substance as a reactant and greater than one substance as the merchandise is the key attribute of a decomposition reaction. For example, in the decomposition of sodium hydrogen carbonate (also recognized as sodium bicarbonate)
-A single-replacement response (sometimes referred to as a single-displacement reaction) is a chemical response in which one aspect is substituted for every other factor in a compound, producing a new aspect and a new compound as merchandise
-A double-replacement response (sometimes referred to as a double-displacement reaction) takes place when components of two ionic compounds are exchanged, making two new compounds. A attribute of a double-replacement equation is that there are two compounds as reactants and two distinctive compounds as product
-A combustion response happens when a reactant combines with oxygen, many instances from the atmosphere, to produce oxides of all different factors as products; any nitrogen in the reactant is transformed to elemental nitrogen, N2. Many reactants, referred to as fuels, incorporate normally carbon and hydrogen atoms, reacting with oxygen to produce CO2 and H2O
A chemical reaction may involve one or more reactants to yiled one or more products.
Types of reactionsBelow we are going to discuss the types of reaction under the following headings;
Synthesis reaction - This is a reaction in which two or more substances come together to yiled a single product.
Decomposition reaction - This involves the breakdown of a substance into new substances.
Single Replacement Reaction- This is a type of reaction in which an atoms replaces another in a compound.
Double Replacement Reaction - This is a reaction in which cations exchange anion partners in a reaction
Combustion - This is a reaction in which a substance is burnt in oxygen.

Answers
Answer:
Even though plants are rooted in the ground, they still move, exert force, and do work.
Plant cells have very strong cell walls that allow pressure to build up inside of the cell as water is absorbed. This pressure is called turgor.
When turgor pressure is high enough in a cell, the cell walls become firm and as a result, the cell becomes rigid and the plant is able to stand tall and straight.
When a plant does not get enough water, the turgor pressure inside of the cells decreases. A decrease in pressure pushing against the cell wall causes the cells to lose their shape and shrink. This causes the plant to begin to droop or wilt.
When the wilted plant gets enough water, the cells will become rigid again, and the plant will stand firm and straight once again.

In 17.2 seconds, a shopping cart is pushed 15.6 meters towards the west. What is the velocity of the cart? (hint~The answer is NOT 3m/s)
Answers
Answer:
0.91m/s due west
Explanation:
Given parameters:
Time taken = 17.2s
Displacement = 15.6m
Unknown:
Velocity of the cart = ?
Solution:
Velocity of a body is the the displacement divided by the time taken.
Velocity = [tex]\frac{displacement}{time}[/tex]
Now insert the parameters and solve;
Velocity = [tex]\frac{15.6}{17.2}[/tex] = 0.91m/s due west

DNA contains the commands that an organism requires to develop, survive, and reproduce. DNA sequences must be transformed into messages that can be used to make proteins, which are the complex molecules that do the majority of the work in our bodies, in order to perform these functions.
What is DNA?Deoxyribonucleic acid is a polymer consisting of two polynucleotide chains that coil into one another to form a double helix.
It contains genetic information in the form, fully operational, growth, and reproduction of all kinds of organisms and viruses. Nucleic acids include DNA and ribonucleic acid.
DNA stores information as a code composed of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
DNA contains all of the instructions that an organism needs to develop, survive, and reproduce.

Which statement best explains what happens to a leaf when it has lost much-needed water?
Answers
Answer:
its turgor pressure decreases
Explanation: This is also important because this function regulates water loss within the plant. Lower turgor pressure can mean that the cell has a low water concentration and closing the stomata would help to preserve water. :-)
When a leaf loses much-needed water, its turgor pressure would decrease. Hence Option A is Correct
What is Turgor pressure ?Turgor Pressure is created in the cells of a leaf when there is enough water. The water stretches the cell membrane outward, creating a kind of pressure.
When the cells lose water, the cell membrane shrinks inward and loses the supporting pressure.
Thus, the turgor pressure created by the presence of water is lost by the absence of water.
The absence of water also affects the rate of photosynthesis and transpiration negatively and not positively. A leaf losing water has no bearing on the atmospheric pressure.
