andrew-mc [135]4 years ago
5 0

Answer:

Gravitational Force is <u><em>inversely</em></u><em> proportional  to the </em><u><em>square of distance </em></u><em>between the objects </em>

F\alpha \frac{1}{d^{2}}

Explanation:

This means if distance is tripled(3 times), then Force reduced to 1/9(square of distance )

If d = 3 ,

F\alpha \frac{1}{3^{2}}

F\alpha \frac{1}{9}

Then , F reduced to 1/9

Relate the intermolecular forces in hydrocarbons to their physical properties and uses
DENIUS [597]

The physical properties of alkenes and alkynes are generally similar to those of alkanes or cycloalkanes with equal numbers of carbon atoms. Alkynes have higher boiling points than alkanes or alkenes, because the electric field of an alkyne, with its increased number of weakly held π electrons, is more easily distorted, producing stronger attractive forces between molecules.

The product of alpha decay of the Nobelium isotope 259No is
Svet_ta [14]

Answer:

Nobelium is made by the bombardment of curium (Cm) with carbon nuclei. Its most stable isotope, 259No, has a half-life of 58 minutes and decays to Fermium (255Fm) through alpha decay or to Mendelevium (259Md) through electron capture.

How to solve 5gNaCl= MolE NaCl
valentinak56 [21]

0.086mole

Explanation:

The problem is very simple. It involves conversion from mass to number of moles of NaCl

What is mole?

 A mole is a unit of measuring chemical substances. It is the amount that contains the avogadro's number of particles.

How is it related and can be converted from mass;

 

Number of moles of a substance = \frac{mass}{molar mass}

Since we know the mass, we can find the molar mass and put into this equation;

Molar mass of NaCl = 23 + 35.5 = 58.5g/mol

Number of moles of NaCl = \frac{5}{58.5}  = 0.086mole
