Explanation:

In chemistry, the process of a chemical change is when the atoms from the reactants rearrange themselves and bond together differently to form one or more new substances with different characteristics than the reactants. Now, after this new substance is formed, the change is called a chemical change.

Now, in cooking Food will undergo a chemical change as it is being cooked. For example, when we boil brown meat, we are causing reactions that change the chemical composition in ways that enhance flavors. Proteins and fibers such as beans when cooked are broken down or undergo denaturation thereby making digestion easier when eaten. Fats like cooking oils are melted while Eggs when boiled are coagulated.

Answer:

The answer is C.

Explanation:

By the Law of conservation of mass, when a element, or product undergoes a physical change, mass always stays the same.

Hope you have a good day.

During physical change the mass of the material remains conserved. The correct option is C.

Even before to and after a physical change, the material implicated is unique architectural the same.

Physical changes include texture, shape, heat, and the beginning of a change in the state of matter. The texture of a substance influences how it feels.

A physical change is simply a change in appearance. The situation has not changed since the change.

Physical change can be seen in the use of cutting paper, melting butter, dissolving salt in water, and breaking glass.

Mass is neither created nor destroyed in chemical or physical changes, according to the law of conservation of mass.

Physical changes occur when the phage of a substance changes without changing its chemical composition.

Thus, the correct option is C.

Explanation:

Protons are positive

Neutrons are neutral

Electrons are negative

Protons and Neutrons are in the nucleus

Electrons are orbiting around the nucleus

The statement that is true about about neutrons is that They have a neutral charge and are found in an atom's nucleus.

Neutrons are electrical charge that is form in the atoms of elements which is neutral that is it's is neither positive or negatively charged.

Neutrons have no charge , they are neutral.

Therefore, The statement that is true about neutrons is that They have a neutral charge and are found in an atom's nucleus.

H2O is covalent so A is false.

Water is in clouds so B is false.

Water is polar so C is false.

D is correct H2O has an imbalance of e- so it is polar. [tex]+H-O(-)-H+[/tex]

An unusual property of water is a polar molecule. Therefore, option D is correct.

When two atoms form a covalent bond but do not share their electrons equally, polar molecules are created. A dipole is created when a portion of the molecule has a slight positive charge and a slight negative charge.

Because the electrons of the hydrogen atoms are "drawn" toward the electrons of the oxygen atom, water (H2O) is a polar molecule. As a result, the hydrogen atoms have a positive charge, whereas the opposite end of the molecule has a negative charge.

Polarity is one of the special characteristics of water because it is composed of polar molecules. Each water molecule has one oxygen atom and two hydrogen atoms (H2O). Polar covalent bonds are created by these compounds. The atoms of hydrogen are positively charged.

Thus, option D is correct.

Answer:

9.34 cm³

Explanation:

From the question given, we obtained the following data:

Mass of magnesium = 16.24 g

Volume of magnesium =.?

To obtain the volume of the magnesium sample, we simply apply the formula for calculating the density of samples. This is illustrated below:

Mass of magnesium = 16.24 g

Density of magnesium 1.738 g/cm³

Volume of magnesium =.?

Density = mass /volume

1.738 = 16.24/volume

Cross multiply

1.738 × volume = 16.24

Divide both side by 1.738

Volume of magnesium = 16.24/1.738

Volume of magnesium = 9.34 cm³

Therefore, the density of the magnesium sample is 9.34 cm³.

Answer:

Because the density of water is one

Answer: A tree grows taller.

Explanation: Cells divide for many reasons. They may divide for growth, death, or to replace something. The cells divide when growth is happening, to allow to produce more cells. For example: When a tree grows taller the cells divide so they can produce more cells. The places in trees where these cell divisions happen, are called “Meristems”. This is where all the activity happens.

The element gallium has equal freezing point and melting point owing to which on pouring liquid gallium in container it becomes a solid.

An element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.

Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.

The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.
