Answer:
Non metal.
Explanation:
The periodic table is arrangements of the elements into a particular order based on their atomic number .
In general when we move from left to right in a periodic table the metallic properties of the elements decreases. So we can say that the left most elements are metals and the right most elements are non metals.
Now as carbon is placed on the right side of the periodic table as it is considered to be non metal.
Water helps in maintaining temperature in cells due to its high heat capacity. This property allows water to absorb or release a large amount of heat without significantly changing its own temperature. As such, cells can keep a stable temperature despite environmental changes.
Water has a high heat capacity, which is the amount of heat it takes to change its temperature. Due to this high heat capacity, it can absorb or release a large amount of heat without a significant change in its own temperature. This helps cells maintain a relatively stable temperature and protect biological processes. For instance, when the external environment is hot, cells can avoid getting overheated as the water in them absorbs and distributes the heat evenly. Similarly, if the environment is cold, the water in the cells releases heat which helps to keep them warm. Hence, regardless of the temperature changes in the environment, the high heat capacity of water aids cells in preserving a relatively even temperature.

b. H2SO4.
c. H3PO4.
d. HCl.
Answer: Option (d) is the correct answer.
Explanation:
An acid which gives only one hydrogen ion or ions upon dissociation in an aqueous solution is known as a monoprotic acid.
Whereas when an acid gives two hydrogen or ions upon dissociation in an aqueous solution is known as a diprotoc acid.
And when an acid gives three hydrogen or ions upon dissociation in an aqueous solution is known as a triprotoc acid.
Therefore dissociation of the given acids in an aqueous solution will be as follows.
Hence, we can conclude that out of the given options, HCl is the monoprotic acid.
Monoprotic acid are acids having only one hydrogen atoms after dissociation into ions from its compound. The monoprotic acid from among the following is HCl. The answer is letter D. HCl → H+ + Cl-. Note that there is only one H+ ion upon dissociation.
The reactant that is totally consumed during a reaction, or the limiting reagent, decides when the process comes to an end. A limiting reagent is the reactant that is used up first in a reaction. Therefore, option A is correct.
A reactant that is completely consumed at the end of a chemical reaction is known as the limiting reagent. Since the reaction cannot proceed without this reagent, the amount of product that can be produced is constrained.
The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be produced. Calculate how many moles of each reactant are present and contrast this ratio with the mole ratio of the reactants in the balanced chemical equation to get the limiting reactant.
The terms limiting reagent and limiting agent may also be used to describe the limiting reactant.
Thus, option A is correct.

Answer: A.) The reactant that is used up first in a reaction
Answer:
CH2O
Explanation:
According to this question:
C = 2.04g
H = 0.34g
O = 2.73g
First, we divide the mass value of each element by its atomic mass to convert to moles.
C = 2.04g ÷ 12 = 0.17mol
H = 0.34g ÷ 1 = 0.34mol
O = 2.73g ÷ 16 = 0.17mol
Next, we divide by the smallest mole value (0.17):
C = 0.17mol = 0.17 = 1
H = 0.34mol ÷ 0.17 = 2
O = 0.17mol ÷ 0.17 = 1
The whole number ratio of C,H,O is 1:2:1, hence, the empirical formula is CH2O.
