Answer:
C.) lowering the pressure
Explanation:
As you can see, the liquid and gas phases are stacked right on top of each other. Since temperature is on the x-axis, this means that these phases exist at the same temperature (disregarding any other variables). This means that changing the temperature would not change the liquid phase to the gas phase.
If we want to get the sample into the gas phase, we need to manipulate the sample based on the y-axis. To lower the sample into the gas phase, we need to lower the pressure, which is the variable on the y-axis. This will work because pressure decreases as you go down the y-axis.
c. burning wood in a campfire
Explanation:
Wood burning in a campfire is an exothermic process.
An exothermic reaction is one in which heat is liberated to the surroundings. The heat content of the reactants is greater than that of the products.
Every burning process is an exothermic reaction.
An exothermic reaction liberates heat to the surrounding.
Other option given takes heat from the surrounding.

Bynari means that the compound is formed by two kind of elements.
You have listed three ions, V 5+, Cl - and O 2-.
Binary ionic compounds are formed by a positive ion and a negative ion, so the possible ionic compound formed by the listed ions are:
1) VCl5, where the number 5 next to Cl is a subscript.
2) V2O5, where the number 2 next to V and the number 5 next to O are subscripts.
Subscripts are used to indicate the number of atoms of each element in the formula.
So, the empirical formula searched are VCl5 and V2O5.
I can give you other examples with more ions.
Ca (2+) and S(2-) => Ca2S2 => CaS
Na(+) and F(-) => NaF
Cs(+) and Br(-) => CsBr
Answer:
The part labelled Y is the chloroplast and its main function is to produce food for the plant in the reactions of photosynthesis.
Explanation:
Plants are autotrophic organisms in that they are able to manufacture their own food. Plants are able to manufacture their own food due to the presence of the cell organelle known as the chloroplast. The plant chloroplast has its own DNA and can reproduce independently, from the rest of the cell. They can as well produce amino acids and lipids required for the chloroplast membrane.
Chloroplasts are green-colored membrane-bound organelles found within the plant cell. Their green color is due to the presence of the pigment, chlorophyll. Chlorophyll in the chloroplasts are responsible for absorbing light energy from sunlight and using this absorbed energy to make simple sugars (carbohydrates) from carbon (iv) oxide and water. This is the main function of the chloroplasts in plant cells.
Photosynthesis occurs in the chloroplasts in two reaction steps:
1. The light reaction - involves the splitting of e=water molecules using the energy of sunlight
2. The dark reactions - carbon (iv) oxide from the air is used to produce sugars.
