Answer:

polymerization

Explanation:

Glucose is converted into starch by the process called polymerization. In polymerization, several simple and soluble molecules of glucose are put together to form a complex, insoluble molecule of starch.

Glucose is soluble , so it is converted to starch so that it can become insoluble and hence it cannot escape from cell , thus it can also be stored.

Stronger

Answer:

A metal is said to be an active metal when it reacts strongly and quickly with other elements due to the electrons in its structure and its ease of sharing the electrons with other elements. ... A metal's reactivity increases as we go from the top to the bottom of the periodic table.

Answer:

Alpha decay

Explanation:

Alpha decay can be blocked with only a sheet of paper.

Extra info : -

In general, alpha particles have a very limited ability to penetrate other materials. In other words, these particles of ionizing radiation can be blocked by a sheet of paper, skin, or even a few inches of air.

Explanation:

Electrons are gained by the atoms. There is no change in the nucleus of the atom and the number of protons remains identical.

Answer:

Ionization is the process by which ions are formed by gain or loss of an electron from an atom or molecule.

Answer:

Ammonium chloride and slacked lime

Explanation:

We can generate ammonia gas in the research centre by slowly heating ammonium chloride (NH4Cl) and slaked lime [Ca(OH)2]. Ammonia gas is lighter than air, requiring its accumulation by the descending displacement of air.

Answer:

Examples of physical change include changes in the size or shape of matter. Changes of state, for example, from solid to liquid or from liquid to gas, are also physical changes. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting.

Answer:

honey has the highest viscosity

According to the given option, honey is the liquid that has the highest viscosity. So, the correct option is D.

Viscosity may be defined as the effects of a liquid by probity of which an internal resistance comes into play when the liquid is in movement and resists the comparable motion between its distinct layers.

Among all the given options, honey possesses more strong intermolecular attractive forces that result in the high compaction of particles in the honey.

After honey, Oil is more viscous followed by milk, and then water.

Therefore, the correct option for this question is D.

A plant without enough space to grow may be impacted by inadequate air as well as light for proper growth.

The competition for space in the tropical rainforest has impacts on two processes:

Light is very important for photosynthesis and the overall well-being of plants. In a tight space, light and air become limited. This means that plants growing in such a space will not be able to photosynthesize optimally.

Plant roots need air to function properly and when becomes inadequate, the entire plant becomes negatively impacted.

The light blue area represents electrons.

An electron is a negatively charged subatomic particle. It can be either free (not attached to any atom) or bound to the nucleus of an atom. Electrons in atoms exist in spherical shells of various radii, representing energy levels. The larger the spherical shell, the higher the energy contained in the electron.

Electrons play an essential role in numerous physical phenomena, such as electricity, magnetism, chemistry and thermal conductivity, and they also participate in gravitational, electromagnetic and weak interactions.

Substance A is less soluble in water than Substance B.

In this experiment, we can see that small amount of substance A is present at the bottom of the beaker which means that some amount of substance A does not dissolve in water.

While on the other hand, no substance B is present at the bottom of beaker which shows that all the substance B is dissolved in water so we can made a conclusion that Substance A is less soluble in water than Substance B.

When glucose reacts with oxygen, it forms an ATP that is used by the given cell. Co2 and h2O are the byproducts.

Answer:

17.19%

Explanation:

mass of oxygen = 7.221 - (1.990 + 2.341)

= 2.890g

Empirical formula of the compound

For carbon,

1.990/12 = 0.1658

For hydrogen,

2.341/1 = 2.341

For oxygen,

2.890/16 = 0.1806

0.1658 ÷ 0.1658 = 1

2.341 ÷ 0.1658 = 14.11

0.1806 ÷ 0.1658 = 1.089

Empirical formula of the compound= CH14O

Molar mass= (1×12) + (14×1) + (1×16)

= 12+14+16

= 42g/mol

percentage composition= 7.221/42 × 100

= 17.19%

Taking into account the Brønsted-Lowry acid-base theory, a base/conjugate acid pair is H₂O/H₃O⁺.

The Brønsted-Lowry acid-base theory (or the Brønsted-Lowry theory) identifies acids and bases based on whether the species accepts or donates protons or H⁺.

According to this theory, acids are proton donors while bases are proton acceptors. That is, an acid is a species that donates an H⁺ proton while a base is a chemical species that accepts an H⁺ proton from the acid.

So, reactions between acids and bases are H⁺ proton transfer reactions, causing the acid to form its conjugate base and the base to form its conjugated acid by exchanging a proton.

In other words, a conjugate base is an ion or molecule resulting from the acid that loses the proton, while a conjugate acid is an ion or molecule resulting from the base that gains the proton:

acid + base ⇄ conjugate base + conjugate acid

In this case, you know:

H₂PO₄ + H₂O → H₃O⁺ + HPO₄⁻

H₂PO₄ behaves like acid because donates an H⁺ proton while H₂O behaves like base because accepts an H⁺ proton from the acid.

So, H₃O⁺ is the conjugate acid of the H₂O and HPO₄⁻ is conjugate base of H₂PO₄.

In summary,  a base/conjugate acid pair is H₂O/H₃O⁺.

Well my  teacher said a more complex way he said chemistry is the science that deals with the properties, composition, and structure of substances.

Explanation:

Finding molar mass of NaOH

We know that

Molar mass of Sodium (Na) = 23 g/mol

Molar mass of Oxygen (O) = 32 g/mol

Molar mass of Hydrogen (H) = 2 g/mol

So,

Mass of 1 mole of NaOH

=> 1 × 23 + 1 × 16 + 1 × 1

=> 23 + 16 + 1

=> 40 g/mol

Now,

Mass = 40 × 0.25

Mass = 10 g
