<span>Mixing cornstarch and water causes a physical change. When the powder cornstarch is mixed with a small amount of water, the mixture is called </span>Oobleck.  It  is a non-Newtonian fluid; it has properties of both liquids and solids. You can slowly dip your hand into it like a liquid, but if you squeeze the oobleck or punch it, it will feel solid.

Give two characteristics of liquid state<br>​
inna [77]

Answer:  Liquids have the following characteristics: no definite shape (takes the shape of its container) has definite volume. particles are free to move over each other, but are still attracted to each other. liquids have lesser densities than solids.  Intermolecular forces of attraction is weaker than solids.  They have considerable space between the particles. Liquids flow from higher to lower level.  Liquids have their boiling points above room temperature, under normal conditions.

I gave many characteristics

Hope this helps :)

The solubility of the ionic compound MX3, having a molar mass of 288 g/mol, is 3.60 x 10-2 g/L. Calculate the KSP of the compoun
GarryVolchara [31]

K_{sp} of the compound is found to be  5.04 ×10^{-10}.

Solubility :Solubility can be define as the amount of a substance that dissolves or mixes in a given amount of solvent at specific conditions.

Solubility equilibrium

Ksp = [A^{+} ]^{a} [B^{-} ]^{b}

Ksp = solubility product constant

A+ = cation in an aquious solution

B- = anion in an aqueous solution

a, b = relative concentrations of a and b

Given,

Solubility = s = 3.60 × 10^{-2} g/L

molar mass = 288 g/ mol

∴ s= 3.60 × 10^{-2} g/L ÷ 288 g/ mol = 1.25 ×10^{-4} mol/ L

Reaction:

MX3 ⇄ M + 3X

           s       3s

K_{sp} =[ M^{+3}] [ X^{-1}]^{3} = solubility product

∴ K_{sp} =[s]^{} [3s]^{3}

∴ K_{sp} = 3 s^{4}

∴ K_{sp} = 3 × (3.60 × 10^{-2} )^{4}

∴ K_{sp} = 503.8848 ×10^{-8}  = 5.04 ×10^{-10}

Type the correct answer in the box. express your answer to three significant figures. an air mattress is filled with 0.55 moles
dmitriy555 [2]

385 L is the volume of the air mattress with 0.55 moles of air inside the mattress and a temperature of 295 K.

<h3>What is an ideal gas equation?</h3>

The ideal gas law (PV = nRT) relates to the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

Using the gas law,

PV=nRT, where n is the moles and R is the gas constant. Then divide the given mass by the number of moles to get molar mass.

Given data:

P= 3.5 kPa

V=?

n= 0.55 moles of air

T= 295K

R= 8.314 (L kPa/mol K)

Putting value in the given equation:

V= \frac{nRT}{P}  

V = \frac{(0.55 moles)(8.314 L kPa/mol k)(295 K)}{3.5 kPa}

V = 385.4132857 L

And whatever the significant figure is asked for, for example, 3 significant figures: the answer would be 385 litres.

Hence, 385.4132857 L is the volume of the air mattress.

Limestone is made of calcium carbonate, CaCO3. Would you use an acid or a base to test a rock sample to determine whether it con
mote1985 [20]

Answer:We will use an acid to test whether sample contains calcium carbonate or not.

Explanation:

Calcium carbonate reacts with acids to give off carbon-dioxide gas ,water and calcium chloride. it is a salt of strong base calcium hydroxide and weak acid carbonic acid.

CaCO_3+2HCl\rightarrow CO_2+H_2O+CaCl_2

Evolution of carbon-dioxide on the reaction is also termed as effervescence.

If the sample contains the calcium carbonate strong effervesces will be observed and if not no effervescence will be observed.

We will use an acid to test whether sample contains calcium carbonate or not.
