The non-contact forces portfolio includes Gravitational force, Magnetic force and Electrostatic force.

<h3>What is non contact force?</h3>

Non contact forces are those forces which are applied on any object without any physical interference or contact.

Some non-contact forces are:

Gravitational force: It acts between two objects and depends on the masses of the object and distance between that objects.
Magnetic force: It acts due to the motion of the charged particles.
Electrostatic force: It is a type of induced force which is generated due to rubbing of two objects but when it is generated it remains even after removing the contact of previous objects.

Hence Gravitational force, Magnetic force and Electrostatic force are the non-contact forces.

Draw the Lewis structure with the lowest formal charges for ClF2+ . Include nonzero formal charges and lone pair electrons in th

masya89 [10]

Answer:

See explanation

Explanation:

The formal charge is obtained from;

Formal Charge = Valence electrons on atom - [number of bonds - lone pair electrons]

The correct structure of ClF2+ is the structure attached to this answer (image obtained from quora) in which the formal charge on fluorine is zero and the formal charge on chlorine is + 1. This is the correct structure because the chlorine is more electronegative than fluorine as expected.

How many moles of MgS2O3 are in 205 g of the compound?

Agata [3.3K]

$Mol = \frac{mass}{molar mass}$

Mass of the compound = 205 g
Molar Mass of compound = ((24) + (2 * 32) + (3 * 16))
= 136 g / mol

∴ # mols in 205g = $\frac{205 g}{136 g / mol}$
= 1.507 mol

CO + 2H2 ⇌ CH3OH ΔH <0

sveta [45]

Answer:

C. The energy released as the bonds in the reactants are broken is greater than the energy absorbed as the bonds in the product are formed.

Explanation:

CO + 2H₂ ⇌ CH₃OH ΔH <0

As ΔH is negative, the given reaction is exothermic.

That means that <em>the enthalpy of the product is less than the enthalpy of the reactants</em>. In other words, part of the energy from the reactants is used to form new bonds (between C and H, for example), while the other part is transfered outside the system as heat.

Thus the correct answer is C.

The half-life of Palladium-100 is 4 days. After 12 days a sample of Palladium-100 has been reduced to a mass of 4 mg. What was t

Degger [83]

Answer : The initial mass of the sample is, 31.9 mg

Explanation :

Half-life = 4 days

First we have to calculate the rate constant, we use the formula :

$k=\frac{0.693}{t_{1/2}}$
