A chemical change occurs when two or more substances join to form new substances with new ______________ properties.

Answers

New physical properties I believe?

A chemical change occurs when two or more substances join to form new substances with new physical properties.

What is physical property?

Physical property of a substance is defined as a property that can be measured and the value explains the state of a physical system. Physical properties can be observed and measured without changing composition.

Physical properties of matter are malleability, solubility, density, conductivity, color, hardness, and electrical conductivity. A change in physical properties is due to physical change and it is a characteristic of a particular substance that can be observed without changing the identity of the substance.

Chemical property is that chemical property can be observed or measured while a substance undergoes in a chemical change.Physical properties of matter are malleability, solubility, density, conductivity, color, hardness, and electrical conductivity.

Therefore,A chemical change occurs when two or more substances join to form new substances with new physical properties.

Compare pressure that fluid applies to the bottom of a glass with the pressure it applies to the sides of the glass

Answers

Answer:

The pressures that fluid applies to the bottom of a glass is comparably more than the pressure it applies to the side of glass because as we know liquid pressure is increased with depth where the bottom of galss have more depth than sides

The pressure at the bottom of the glass is more as compared to the sides of the glass because the pressure increases with increase in depth.

What is pressure?

Pressure is defined as the force applied on an object perpendicular to it's surface per unit area over which it is distributed.Gauge pressure is a pressure which is related with the ambient pressure.

There are various units by which pressure is expressed most of which are derived units which are obtained from unit of force divided by unit of area . The SI unit of pressure is pascal .

It is a scalar quantity which is related to the vector area element with a normal force acting on it.It is distributed over solid boundaries and across arbitary sections of fluid normal to the boundaries at every point.

How is redshift different from blueshift?​

Answers

Answer:

Red light wavelengths tend to be more stretched out the further you are from the object. Blue light wavelengths tend to be closer together. Blueshift light tends to be emitted from objects that are moving closer. The further away, the more red the lights spectrum has.

Redshift and blueshift portray how light shifts toward shorter or longer wavelengths as objects in space ( such as stars or systems) move closer or more distant absent from us. In the event that an protest moves closer, the light moves to the blue conclusion of the range, as its wavelength get shorter.

What is an ecosystem?

An ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

People rarely use krypton, xenon, and radon because there known but are rarely mentioned.

Explanation:

Hope this helps

Elements which are most similar to neon are helium,argon,krypton,xenon and radon as they have similar outer electronic configuration.

What is electronic configuration?

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.
