Explanation:

In alpha decay alpha ray comes out . Apha ray is nothing but nucleus of helium atom whose atomic no  is 2 and atomic weight is 4 . Hence in alpha decay , atomic weight reduces by 4 and atomic no reduces by 2. For gamma emission , there is no change in atomic number and atomic mass.

First, the lining may consist of loose, smaller bits of the same materials that have been incorporated into the latticework of the nest. These finer materials are utilized to shed water, deter pests, conceal the eggs from predators, insulate, and cushion them. ... They also serve to insulate and cushion the eggs.

Answer:

18 electrons

Explanation:

Answer:

18 electrons

Explanation:

Ca has 20 electrons. Ca^2+ has 18 electrons

Answer:

0.93 grams per milliliter

Explanation:

Density is the division of mass by volume. It is how "hefty" an object is; for example, wood isn't very "hefty" but metal is. The density is measured in mass over volume, so it is 9.3/10. After applying units, it is 0.93 grams per milliliter.

Answer and Explanation:

I have always lived in the same region. The region where I live is flat and stable, the site has asphalt and the climate is tropical with a long summer and poorly defined seasons. My region does not have drastic changes and temperature and the climate is hot most of the year. For this reason, it is necessary to use materials that are thermal insulators, on the contrary we need to use materials that are not good thermal insulators such as concrete blocks, bricks, cement and ceramics, we will also need common tiles and rafters to support them.

Answer:

There arr 1.5*1024 molecules in 2.40 moles of H2O.

Answer:

Sample 1 = 78°

Explanation:

As per the question, while testing the solubility of a solution comprising of water and carbon dioxide, sample 1 is likely to have the lowest solubility with the temperature of the water being 78°, the maximum. The reason for this result is that the 'solubility of carbon dioxide in the water' falls with an increase in the temperature due to the increase in kinetic energy which will enhance the motion between the molecules and allow them to escape.' Thus, the water with maximum temperature will have the lowest solubility. Hence, sample 1 is the correct answer.

Answer:

Option B:

Conduction

Explanation:

Conduction is the transfer of heat from one molecule to another between two solids that are in direct contact with each other. For the conduction of heat to occur, the medium involved must be solid. This is because the molecules of solids are closely packed together and they cannot freely move about. The heat flowing through them can easily be passed on from one molecule to the other until it reaches all the parts of the object. This is exactly what will happen to the iron bar. Thermal energy from one end of the bar will get transferred between the molecules of the iron bar until it reaches the other end.

Convection on the other hand involves the transfer of heat through a liquid medium.

Radiation involves teh transfer of heat in a vacuum.

Answer:

b) conduction

Explanation:

About five million million hydrogen atoms could fit. Some factors would affect that number like the area of the head and the size of atoms (as well as attractions between atoms). Some atoms are larger than others.

If 1.136 × 10⁷ atoms of oxygen can fit across the head of a pin whose diameter is 1.5 × 10⁻³ m, the atomic radius of oxygen would be 6.60 × 10⁻¹¹ m.

The head of a pin is 1.5 × 10⁻³ m in diameter. If 1.136 × 10⁷ atoms of oxygen can fit across the head of a pin, the diameter of each oxygen atom would be:

[tex]\frac{1.5 \times 10^{-3}m }{1.136 \times 10^{7}atom} = 1.32 \times 10^{-10}m/atom[/tex]

The atomic radius of oxygen would be half of its diameter.

[tex]\frac{1.32 \times 10^{-10} m}{2} = 6.60 \times 10^{-11} m[/tex]

If 1.136 × 10⁷ atoms of oxygen can fit across the head of a pin whose diameter is 1.5 × 10⁻³ m, the atomic radius of oxygen would be 6.60 × 10⁻¹¹ m.

An independent variable is the cause. Its value is independent of other variables in your study. A dependent variable is the effect. Its value depends on changes in the independent variable

Variables are the factors or the numbers used as a quantity. The dependent variables are conditional, and the independent variable is the cause that affects the result.

The independent variable of an experiment is the data that is the cause of the experimental design. Its value and result do not depend on other factors and conditions. These values are manipulative and are set by the researcher.

The dependent variables, on the other hand, vary based on the other factors and variables and are the effect that is based on the response and the outcome of the other variables. It is the tested or the measured value.

Therefore, the independent and dependent variables differ based on cause and effect.

Answer:

C.  increasing digestion

Explanation:

Answer:

False. Answer in pic above

In fact protons have no role in chemical reactions. The regrouping of atoms itself forms the new products in chemical reactions. The reactions involves the loss/gain or sharing of electrons.

A chemical reaction is a chemical change in which two or more atoms combine together to form a new product or a compound decomposes to form its constituent compounds. This  involves breaking or making of bonds.

In a chemical reaction, no change occurs in the nuclear composition but the valence electrons are involved in the reaction. Atoms loss or gain electrons or share valence electrons with other atoms to form ne compounds.

The electrostatic force of attraction or the overlapping of atomic orbitals make the new products in a chemical reaction. Hence, the statement is false.

The chemical symbol always begins with a capital letter.

Explanation:

Answer:

c

Explanation:

The chemical symbol of an element always starts with an chemical letter so here the answer is that the chemical symbol always begins with a capital letter.

It can be seen in the different elements chemical symbol .

For example, Tin is having chemical symbol as Sn while lead is having chemical symbol as Pb.

In both these elements, the chemical symbol starts with a capital letter but none of these have their symbol starts with same letter as their name.

Randy went into the classroom without the teacher being present. He opened  containers of chemicals without the teacher's consent. Randy is making contact with the chemicals on his skin.

I hope this helps! I haven't done lab science in a while so I'm trying to remember the safety precautions.

Randy went into the classroom without the teacher being present and opened  containers of chemical, making contact with chemicals on skin leads to skin reaction.

So Randy should follow the lab safety rules while entering into lab.

After entering lab wear apron and gloves along with safety goggles if working with any hazardous or infectious substance.

Fully aware about the hazards of the materials, properly trained to handle lab equipment, chemicals should be adequately labelled.

Taste or smell chemicals are prohibited, never pour already stored chemicals, chemical hygiene plan should be developed for specific hazards.

Avoid to adopt un-tested and unauthorized experimentation, Clean up all chemical spill, Laboratory induction should be carried out .

Avoid storage of any edible items in the refrigerator along with lab chemicals and specimens, clean the work station after completing experiment and sterilization should be done before starting experiment.
