Answer:
2-carbohydrate
Explanation:
Sucrose belongs to the carbohydrate family. It is a disaccharide which is derived from the condensation of glucose and fructose.
In the body, they are sources of energy for living processes. Upon hydrolysis such disaccharide produces tow monosaccharide units. Food substances that are energy rich will contain some of these organic molecules.Sucrose is a specific type of organic compound classified as a carbohydrate and the correct option is option 2.
Carbohydrates are essential biomolecules made up of carbon, hydrogen, and oxygen atoms. Sucrose, also known as table sugar, is a disaccharide formed by the chemical bonding of one glucose molecule and one fructose molecule.
Plants produce sucrose through photosynthesis and use it as a readily available source of energy. When consumed by animals, including humans, sucrose is broken down into its constituent monosaccharides to provide fuel for various cellular processes.
Thus, the ideal selection is option 2.

Why do electronegativity charts often give no values to the group 18 elements?
Answer:
Because they have complete electronic configuration
Explanation:
Group 18 elements are known as the noble or inert gases. The elements in this group are non-reactive because they have complete electronic shell configuration.
Electronegativity is the tendency of an atom to attract electrons. The reason why atoms attracts electrons is to have a stable configuration like those of the noble gases. Since the noble gases do not require any extra-electrons to attain stability, they have 0 electronegative values.Please help: Which is an example of an internal stimulus

what are the similarities and differences between the crocodile , sheep , and gorilla digestive system?
Answer: Crocodile is a reptile whereas sheep and gorilla are the mammals.
Explanation:
Crocodile, sheep, and gorilla have alimentary canal in their digestive system. The urea is the common excretory waste.
Mouth is typically large in case of crocodile and comparatively small in sheep and gorilla.
In crocodile more sharp teeth are present as compared to sheep and gorilla for mastication of food and capturing the prey like fish or large animals like zebra.
The crocodile palate is more stronger than sheep and gorilla because it enable it to chew the bones of the prey.

Given the name of an element and the number of neutrons, find the mass of an Isotope
The given element nitrogen have 7 electrons and 7 protons. Mass number is the sum of number of protons and neutron. The number of neutrons is 7. Thus mass number of the isotope is 14.
What is nitrogen?Nitrogen is 7th element in periodic table. It is an electronegative element and is included in p block. Nitrogen exists as gas but sometime it can be liquified under high pressure.
Isotopes are atoms with same atomic number and different mass number. Nitrogen have two isotopes. N-14 and N-15. Mass number is the sum of number of protons and neutrons.
Even though isotopes are different in mass number their chemical properties will be similar but there exists slight changes in their physical properties.
Here, we have 7 protons and 7 electrons therefore, the mass number 14.Thus the isotope given in the diagram is N-14.

When 50.0 mL of 1.000 M HCl is reacted with 50.0 mL of 1.000 M NH4OH, the solution's temperature increases 8.65 °C. Calculate qsolution in units of kJ. The specific heat of the salt solution is 4.184 J/g-°C and the density is 1.010 g/mL.
Answer:
Explanation:
Total volume of solution = 100 mL .
Total mass of the solution = 100 x 1.01 g
= 101 g
specific heat of solution = 4.184 J/g-°C
rise in temperature = 8.65 °C
heat released = mass x specific heat x rise in temperature
= 101 x 4.184 x 8.65
= 3655.35 J
= 3.655 kJ .
qsolution = 3.655 kJ .

Explanation:
how can air produce a pressure
IN OWN WORDS NOT FROM GOOGLE
Answer:
Gas pressure is caused when gas particles hit the wall of their contains. the more often the particles hit the walls, and the faster they are moving when they do this , the higher the pressure .
Explanation:
If I place a balloon in my fridge that initially has a pressure of 1.02 atm and a
temperature of 11.2 °C, what will be the pressure (in atm) of the balloon when it is
fully cooled to 4.00°C by my refrigerator?
Answer:
P₂ = 0.99 atm
Explanation:
Given data:
Initial pressure = 1.02 atm
Initial temperature = 11.2°C
Final pressure = ?
Final temperature = 4.00°C
Solution:
Initial temperature = 11.2°C (11.2+273 = 284.2 K)
Final temperature = 4.00°C (4.00+273 = 277 K)
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
1.02 atm / 284.2 K = P₂/277 K
P₂ = 1.02 atm × 277 K / 284.2 K
P₂ = 282.54 atm. K /293 K
P₂ = 0.99 atm

The following statement that it will provide information to help formulate a new hypothesis in the future is true about a hypothesis that is proven to be inaccurate.
What is hypothesis?Hypothesis can be defined as an assumption which is made for the sake of argument . It is an interpretation of a practical condition for which action needs to be taken.It is defined as a tentative assumption which is made to test logical consequences.It is an antecedent clause of a statement which is conditional.
It is constructed before research. There are six types of hypothesis 1)simple hypothesis 2) complex hypothesis 3) directional hypothesis 4)non-directional hypothesis 5) null hypothesis 6)casual hypothesis
