Answer:      The reactivity of group 7 elements decreases down the group because, as you go down the group: The atoms get larger. The outer shell gets further from the nucleus. The attraction between the nucleus and electrons gets weaker, so an electron is less easily gained.

Answer:

The density is 2.5625g/mL. Hope this helped! :)

Explanation:

M= 8.2g                                                                               D=M/V

V= 28.3-25.1=3.2mL

D=8.2g/3.2mL

D= 2.5625g/mL

Answer:

The last naturally occurring element to be discovered was francium (87) in 1939. Since that discovery, plutonium (94), neptunium (93) and astatine (85), which were initially created in the lab in 1940, have since been found in nature.

Explanation:

The -ium suffix is just a Latin suffix that creates abstract nouns, therefore, it's being used to construct scientific component names from their nomenclature origin, including such minerals (calcium from calx) or person names (gadolinium), and  further discussion can be defined as follows:

A chemical symbol is a shorthand method of representing an element. Instead of writing out the name of an element, we represent an element name with one or two letters. As you know, the periodic table is a chemist's easy reference guide. ... Each element is represented by a chemical symbol consisting of letters

Answer:

dendrites in your sensory neurons

Explanation:

Sensory neurons are first activated, then the stimulus is transmitted horizontally between them, spreading perception through the olfactory bulb that captures the smell of a baked cookie.

After this, the axons are activated to transmit to the motor neurons that will carry out the action of walking towards the kitchen.

Answer:

Dalton used creativity to modify Proust's experiment and interpret the results. Millikan used creativity to develop a way to measure the charge on an electron. Thomson used creativity to interpret the results of the cathode ray tube experiment.

Explanation:

Creativity enables scientists to devise new ways of solving old problems.

I do not know what your material contains, however, creativity is key in scientific investigation. The term "science" is coined from the Latin word "scientia" which means knowledge.

In science, we endeavor to create new knowledge through research and innovation. This requires that a scientist must think of new and efficient ways of solving old problems. This underscores the centrality of creativity in scientific investigation.

Answer:

Temperature - Independent variable

The solubility of CO2 and Solubility of O2 - Dependent variable

Explanation:

There are always two variables in an experiment: Independent and dependent variables.

Independent variables are defined as the variables that can be controlled or changed to measure its effect on the dependent variable and the dependent variable is influenced by the change in Independent variables.

In the given example, the temperature is the Independent variable and the solubility of CO2 and Solubility of O2 is the dependent variable because the solubility of CO2 and O2 decreases as temperature increases.

Hence, the correct answer is:

Temperature - Independent variable

The solubility of CO2 and Solubility of O2 - Dependent variable

According to law of conservation of matter , the mass of the trees got converted  fro one form of matter to another.

According to law of conservation of matter, it is evident that matter is neither created nor destroyed rather it is restored at the end of a chemical reaction .

Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.

Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Antoine Lavoisier in the year 1789.

Explanation:

This number will be used to tell you how far your seismograph is from the epicenter of the earthquake.

Answer:

The distance between the beginning of the first P wave and the first S wave tells you how many seconds the waves are apart.

Explanation:

This number will be used to tell you how far your seismograph (an instrument that measures and records details of earthquakes, such as force and duration) is from the epicenter (the point on the earth's surface vertically above the focus of an earthquake) of the earthquake. Measure the distance between the first P wave and the first S wave.

Answer:

1. chemical 2. potential

Explanation:

energy, potential energy, is stored in the covalent bonds holding atoms together in the form of molecules. This is often called chemical energy.Energy is found in different forms, but all energy falls into the following two categories – potential energy and kinetic energy. Potential energy is stored energy, or the energy of position. It consists of the following forms: Chemical energy is energy stored in the bonds between atoms in molecules.

The form of energy stored in the bonds between atoms is chemical energy. This form of energy falls into the potential energy category.

The term chemical energy is defined as the energy of chemical substances that is released when they are undergo the process of  chemical reaction and covert into the another substances.

The chemical energy is used to create heat and electricity along the world. Some peoples also burn these fuels on more minor scales to formed heat to keep buildings warm. They burn fossil fuels like natural gas, oil, and petroleum to produce steam to turn turbines that formed heat and electricity.

The energy stored in chemical bonds is called as chemical energy therefore, it is a form of potential energy. The examples of potential energy are the energy of water present behind a dam.

Thus, The form of energy stored in the bonds between atoms is chemical energy. This form of energy falls into the potential energy category.

✨Thanks!!!!☺✨

Answer:

Explanation:

The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside. This is particularly confusing in the case of non-conservative forces, where energy is converted from mechanical energy into thermal energy, but the overall energy does remain the same. The only way to use energy is to transform energy from one form to another.

Answer:

The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. The second law of thermodynamics states that the entropy of any isolated system always increases.
