Multiply 21 miles by 60, so you get it in minuets. 21×60=1260 miles per minute. Alan's cart is faster

When you dissolve solid sugar into water, this new solution will taste sweet. the sugar went through a chemical change?
dybincka [34]
Basically the sugar breaks down until it’s eventually evaporated and spreads to different parts of the water solution and while it’s spreading the chemicals and the flavors in the sugar are going into the molecules and atoms in the water and mixing to make the water solution taste sweet just like sugar. So i would say it would be a physical change not a chemical change.

6.0 L of oxygen gas is at a temperature of 5K. If the temperature of the gas is lowered to 1K at constant pressure, what is the
DerKrebs [107]

Answer:

THE NEW VOLUME AT 1 K IS 1.2 L

Explanation:

Using Charles' law which states that the volume of a given gas is directly proportional to its temperature provided the pressure remains constant.

Mathematically written as;

V1/T1 = V2/T2   at constant pressure

V1 = Initial volume = 6L

T1 = initial temperature = 5K

T2 = Final temperature = 1K

V2 = final volume = unknown

Re-arranging the equation by making V2 the subject of the equation, we obtain;

V2 = V1 T2 / T1

V2 = 6 * 1 / 5

V2 = 1.2 L

The new volume of the gas sample at 1 K is 1,2 L

In general terms, how does each of the following atomic properties influence the metallic character of the main-group elements i
vekshin1

Metallic property also rises with increasing atomic radius. Metallic character reduces with an increase in the amount of outer electrons.

<h3>What is atomic radius?</h3>

A chemical element's atomic radius, which is typically the average or typical distance between the nucleus's core and the outermost isolated electron, serves as a gauge for the size of an atom. There are numerous non-equivalent definitions of atomic radius since the border is not a clearly defined physical entity. Van der Waals radius, ionic radius, metallic radius, and covalent radius are the four most frequently used definitions of atomic radius. The atomic radius is often measured in a chemically linked condition because it is difficult to isolate individual atoms to measure their radii separately. However, theoretical computations are easier when considering isolated atoms.

Please answer each thank you
liubo4ka [24]

Answer:

Properties of Metals:      

- Shiny

-Malleable

-Good Conductors of electric current

- Good conductors of heat

Properties of Non-metals:

- Dull

- Not Malleable

- Bad conductors of electric current but good electric insulators

- Poor conductors of heat

Note: The first dash for the Properties of metals goes with the first dash of Properties of Non-metals and so on.
