Several properties of water are shown. Classify each property as a physical property or a chemical property.
max2010maxim [7]

can be split into hydrogen and oxygen             chemical property

is liquid at room temperature                              physical property

has a density of 1.0 g/cm³                                    physical property

reacts with certain metals                                  chemical property

Explanation:

The physical properties of matter are the properties that occur when no change is occurring to a matter. They are usually observed with our senses or some simple laboratory experiments.

Some of the physical properties are boiling point, density, state of matter, e.t.c

The chemical properties are the properties that occurs when a matter undergoes some chemical changes.

For example rusting, decomposition, reactivity e.t.c

One beaker contains 100 mL of pure water and second beaker contains 100 mL of seawater. The two beakers are left side by side on
gayaneshka [121]

Explanation:

When we add a non-volatile solute in a solvent then due to the impurity added to the solution there will occur an increase in the boiling point of the solution.  

This increase in boiling point will be known as elevation in boiling point.

As one beaker contains seawater (water having NaCl) will have some impurity in it. So, more temperature is required by seawater to escape into the atmosphere.

Whereas another beaker has only pure water so it is able to easily escape into the atmosphere since, it contains no impurity.

Thus, we can conclude that level of pure water will decrease more due to non-volatile solute present in it as compared to seawater.

Please help! I'm not a smart 7th grader, on this assignment you write if it's convection, radiation, or conduction, then you wri
sattari [20]
#8 would be radiation
Because of the heat it produces for the air in the home
#9 Conduction
Because it’s preventing physical heat transfer
#10 convection
Because it is stopping the air from rising
#11 Radiation
Because the heat is emitting from the stove and warms him, but not by direct contact
#12 Conduction
Because the heat transfers from the top of the stove to the cats fur.
#13 Conduction
Because the stove under it heats it through contact
#14 I think Radiation
Because the heat warms up the dish through the air in the oven
#15 Radiation
Because the heat is emitting from the fire.
#16 Conduction
Because the blanket is warming you through physical contact.

I’m not completely sure but the is the best I got. Good luck!

How many sucrose molecules will be in 250 grams
sasho [114]
<h2>Answer:</h2>

We will need to know Avogadro's number and the molar mass of sucrose for this problem to do dimensional analysis.

  • Avogadro's number: 6.022 × 10²³ molecules
  • Molar mass of sucrose: 342.2965 g/mol

250g × \frac{1 mol}{342.297g} × \frac{6.022 * 10^{23} molecules}{1 mol} = 4.398 molecules

There are <em>4.398 sucrose molecules </em>in 250 grams of sucrose.
