What state of matter has no visible shape and fills its container?
A: solid
B: liquid
C: has

Answer:

The ranking of matter from the LEAST amount of energy to MOST amount of energy is;

B. Solid, Liquid, Gas

Explanation:

The kinetic energy of the particles that make of matter depends on the temperature of the particles and the particles are constantly vibrating

Solid state (Least amount of energy)

In the solid state, the matter is held in solid (rigid) crystal lattice and the particles are rigidly located next to other adjacent particles and stacked up layer by layer

Liquid state (Intermediate amount of energy)

As the temperature of the particles are increased by heating, the particles (atoms and molecules) gain more kinetic energy and their vibration is increased which on further heating, leads to the breaking of the lattice bond of the solid state and the particles are then readjusted to exist side by side rather than being stacked on one another and the assume the liquid state

Upon further heating the particles in the liquid acquire more energy and are  and rather than exist side-by-side, they are able to exist as individual particles in the gaseous form

Gaseous state (Most amount of energy)

From the kinetic theory of matter, the molecules of matter in the gaseous state contains enough energy which is more than the intermolecular forces of attraction such that the particles are able to move and occupy the entire volume of the container in which it is placed

Therefore, the correct option is Solid, Liquid, Gas.

gas > liquid > solid

%yield = 88.5%

Given

Reaction

Cu(s) + 2 AgNO₃(aq) → Cu(NO₃)₂(aq) + 2Ag(s)

Required

The percent yield

Solution

mol AgNO₃(MW=169,87 g/mol) :

= mass : MW

= 127 : 169.87

= 0.748

mol Ag from equation :

= 2/2 x mol AgNO₃

= 2/2 x 0.748

= 0.748

Mass Ag (theoretical) :

= mol x Ar Ag

= 0.748 x 108

= 80.784

% yield = (actual/theoretical) x 100%

%yield = 71.5/80.784 x 100%

%yield = 88.5%

Answer:

C. Na and F

Explanation:

The reaction between Sodium and fluorine will proceed more quickly and easily of all the given reaction choices.

This is because fluorine is the most electronegative element and sodium is more electropositive when compared to Lithium.

Answer:

Salinity is a measure of the 'saltiness' of seawater, or more precisely the amount of dissolved matter within seawater.

Answer: addition and elimination

Explanation:

In addition you add and in elimination you remove (or subtract)

The reactions that are the reverse of one another are addition and elimination. Details about types of reactions are as follows.

A reaction is the transformation in which one or more substances is converted into another by combination or decomposition.

Reactions can be of different types as follows:

However, addition and elimination reactions are reverse of one another because addition involves adding substances while elimination involves removing substances.

The wavelength of the radiation : λ=5.792 x 10⁻⁸ m = 5.792 x 10⁻⁶ cm

Region of Ultraviolet

Given

A frequency : 5.18 x10¹⁵ Hz

Required

The wavelength

Solution

Frequency (f): the number of waves per second  

Wavelength (λ): the distance from one crest/one trough to another

Fast wave propagation (v): the distance traveled by waves per unit of time  

v= 3 x 10⁸ m/s

General formula :

v = λ.f

λ=v/f

Input the value :

λ=3.10⁸ : 5.18.10¹⁵

λ=5.792 x 10⁻⁸ m = 5.792 x 10⁻⁶ cm

Region of Ultraviolet (4000 - 10 A°, 4 x 10⁻⁵ - 10⁻⁷ cm,7.5 x 10¹⁴ - 3 x 10¹⁷ Hz)

Answer: in the daytime the sun is out so the stars are not visible becuase the suns reflection! At night When you gaze at the constellations, every star produces an image that's the same size, but your retina isn't sensitive enough to respond to the outer parts of those images except for the brighter stars — which therefore look bigger than the fainter ones.

Answer:

Volume of the sulfuric acid (25cm³), same mass of each metal (1g)

Explanation:

In an experiment, the CONTROL VARIABLE also known as constant is the variable that is kept unchanged for all groups in an experiment. This is done in order not to influence the outcome of the experiment.

In this case, students are trying to investigate the reactivity of four different metals. They added 1 g of each metal to 25cm³ of sulfuric acid and recorded the temperature change. Based on the explanation of control variable above, the VOLUME OF SULFURIC ACID (25cm³) and the MASS OF EACH METAL (1g) are the CONTROL VARIABLES because they are the same or unchanged in this experiment.

Given

Reaction

N2(g) + O2(g) + 182.6 kJ → 2 NO(g)

Required

The heat of formation

Solution

In the above reaction, the heat of the reaction is located on the reactant side which indicates that the formation of nitric oxide requires heat (endothermic reaction).

In the above reaction the heat required to form 2 moles of NO, so the heat required for each mole is:

+182.6 kJ : 2 = =+91.3 kJ/mol

Answer:

3 atoms of O

8.57g

Explanation:

The problem here is to find the mass of oxygen in the compound and the number of atoms of oxygen.

 The formula of the compound is:

 NaHCO₃;

   Here we have:

      1 atom of Na

     1 atom of H

     1 atom of C

     3 atoms of O

So there are 3 atoms of O

To find the mass of oxygen , we use the molar mass of oxygen;

     Molar mass of oxygen  = 16g/mol

 Mass of oxygen  = [tex]\frac{3(16)}{84.01}[/tex]  x 15  = 8.57g

Answer:

3012.51×10²³ atoms of Ne

Explanation:

Given data:

Mass of Ne = 10090 g

Number of atoms = ?

Solution;

Formula:

Number of moles = mass/ molar mass

Molar mass of Ne = 20.17 g/mol

Number of moles = 10090 g/ 20.17 g/mol

Number of moles = 500.25 mol

Number of atoms:

1 mole contain 6.022×10²³ atoms

500.25 mol × 6.022×10²³ atoms / 1 mol

3012.51×10²³ atoms
