The correct answer is cation Ni +2 and anion S 2-.

Nickel sulfide

It is discovered that the bonding in NiS is remarkably similar to that in NiO, with a covalent component resulting from bonds between the Ni 3d and the S 3p atom and an ionic contribution resulting from the donation of the Ni 4s electron to the S atom.

With heated concentrated nitric acid or aqua regia, NiS can be easily reactively dissolved, which is followed by sulphur precipitation.

F belongs to Group 7A, while Ni is in Group 5A. (EN: N=3.0, F=4.0) The NF3 molecule and each N-F bond are both polar. F possesses a partial positive charge in the N-F bond. The NF3 molecule and each N-F bond are both non-polar.

Answer:

In order to draw the 3-D structure of an organic compound, we can use wedge-dash representation.

Answer: 0.1533 moles of NH3

Explanation: The reaction need 2 moles of ammonia and 3 moles of copper oxide to take place. If you have 0.230 moles of copper oxide you need:

0.230/3=0.0767*2=0.1533 moles of NH3

The molar mass of the gene is  2.22 * 10^4 g/mol and the freezing point depression is  3.35 * 10^-5 °C

We know that the osmotic pressure is obtained by the use of the formula';

π = iCRT

i = Van't Hof factor

C = concentration of the solution

R = gas constant

T = temperature

C = π/iRT

C = 0.340/1 * 62.4 * 298

C = 1.8 * 10^-5 M

Now;

n/M = C * V

12 * 10^-3/M =  1.8 * 10^-5  * 30 * 10^-3

M =  12 * 10^-3/1.8 * 10^-5  * 30 * 10^-3

M =  12 * 10^-3/ 5.4 * 10^-7

M = 2.22 * 10^4 g/mol

Mass of the solution is obtained from density * volume = 0.997 g/mL * 30.0 mL = 29.91 g

Molality of the solute = 12 * 10^-3g/ 2.22 * 10^4 g/mol * 1/ 29.91 * 10^-3

= 1.8 * 10^-5 m

ΔT = K m i

If the surface temperature on Mercury has been measured to be 603 K, this temperature is equivalent to 329.84°C (degrees Celsius).

Temperature is the measure of cold or heat, often measurable with a thermometer.

Kelvin, which is denoted by K, is the International System of Units (S.I unit) or the base unit of thermodynamic temperature.

However, Kelvin can be converted to degree Celsius as follows:

K = 273.16 + °C

According to this question, the surface temperature on Mercury has been measured to be 603 K. This temperature can be converted to °C as follows:

603K = 273.16K + °C

°C = 603 - 273.16

°C = 329.84°C

Therefore, if the surface temperature on Mercury has been measured to be 603 K, this temperature is equivalent to 329.84°C (degrees Celsius).

pls check your question again i think you question is wrong.

a. (i) The bonding in iron is not covalent.

    (ii) NaCl i.e. sodium chloride do not have covalent bond.

    (v) Argon is an inert gas do not form molecules by any sort of bonding.

b. A substance XY, formed from two different elements, boils at -33 °C is XY likely to be covalent. Since its boiling point is much below zero degree Celsius, the binary compound is a gas at room temperature.

Metallic bonding is a type of bonding that exists in iron. Iron is a metal, and all metals have a specific kind of connection that isn't covalent or ionic called metallic bonding. The outer shells of neighboring atoms overlap during metallic bonding, and the outer shell electrons are free to move about the lattice.

The hydrogen and oxygen atoms in water share their electrons hence covalent bonding.

Sodium Chloride (NaCl) is a pure ionic compound and not a covalent compound. The two atoms transfer their electrons to form ions, Na+ and Cl-.

The two oxygen atoms share two pairs of electrons, so two covalent bonds hold the oxygen molecule together.

Argon is an inert gas do not form molecules by any sort of bonding.

For the substance XY, its boiling point is beyond zero which happens to be present in case of gases thus it is a covalent substance.

Applied force define as the force applied to by an object to other object.applied force is contact force or a non contact force.

Friction force is the force exerted by a surface that resist the motion of body or against motion of body.friction is contact force. When the applied force increases , the frictional force also increases. when the applied force is larger than friction force object will move.

Example , if we applied force to the right direction the friction force acts in left direction.that is opposite to applied force.

Explanation:

Bc my mom told me

The mass of the object is obtained as  608.5 grams.

The term density refers to the ratio of the mass to the volume of an object. The density of an object does not change thus we could use the density of an object to identify that object. If we have the density of the object, that alone could be used to trace the exact kind of material that we are dealing with.

Now we know that the density of the object is 6.095 g/cm^2

Volume of the object is obtained as  99.830 mL

Density = mass/volume

mass = density * volume

mass = 6.095 g/cm^2 *  99.830 mL

mass = 608.5 grams

Hence, the mass of the object is obtained as  608.5 grams.

The molarity of the given solution will be 0.434 M  . Since the concentration is given in percentage in mass/volume  form, the molarity of the solution will be calculated as follows:

Here,

Concentration= 4.61% m/v

Molecular mas of xylene= 106.2g/mol

Moecular mass of toulene = 92.30g/mol

Molarity is defined to be as moles of solute present per liter of solution.  Here  we are dealing with two liquids, the one having greater amount will be taken  as the solvent and the one having lower amount will be taken as the solute

4.61% m/v = 4.61 g xylene/100 ml toulene

= 4.61 g xylene/L

Now Converting this to moles / L we will get:

46.1 g xylene  x 1

mol/106.2 g = 0.434 moles xylene per L of toulene

Molarity (M) = No of moles of solute  / Volume of solute( L)

= 0.434 moles / 1 L

= 0.434 M

So, the concentration of the given solution in molarity will be equal 0.434M

Answer:

104.9 g

Explanation:

If you add a piece of silver to water which increases the volume of the water from 20 mL to 30 mL, according to water displacement, the piece of silver must be 10 mL (30 mL - 20 mL = 10 mL).

You can find the mass by multiplying the volume of silver by the density. The denisty exists as a ratio comparing the mass (g) of silver per every 1 mL. It is important to arrange the ratio in a way that allows for the cancellation of units (mL should be in the denominator).

  10 mL             10.49 g
--------------  x  -----------------  =  104.9 g
                           1 mL

0.6066 moles of water are produced by complete ammoxidation of 145 g of o-xylene.

Number of moles are calculated by dividing the mass by the molar mass of the substance.In the reaction between o-xylene ,ammonia and oxygen pthalonitrile  is produced.

Here, the number of o-xylene is calculated by the above mentioned formula which is 1.365 moles.Then, as per stoichiometry and balanced chemical equation ,

1.365 moles of o-xylene×8 moles of water/1 mole of xylene ×18 g water

=0.6066 moles

Thus,0.6066 moles of water are produced from 145 g of o-xylene.
