<span>Answer: Graham's law of gaseous effusion states that the rate of effusion goes by the inverse root of the gas' molar mass. râšM = constant Therefore for two gases the ratio rates is given by: r1 / r2 = âš(M2 / M1) For Cl2 and F2: r(Cl2) / r(F2) = âš{(37.9968)/(70.906)} = 0.732 (to 3.s.f.)</span>

sleet_krkn [62]

Answer:

here is something to help you out

Explanation:

Gravitation force is well known word in physics. Gravity force exists in all masses objects, i.e. all the object which have masses. The gravitational force is exhibited from the lighter mass to heavier mass.

The expression for the gravitational force is,

Here, F is the gravitational force, G is the gravitational constant,  is the mass of one object,  is the mass of another object, and R is the distance between the two objects.

Thus, the gravitational force is directly proportional to the product of the mass of the massive objects and inversely proportional to the square of the distance between the objects. This is known as Newton's law of gravitation.

The gravity force exists in atoms, light particles, planets, and starts as their energies and masses are same.

. Nine planets namely Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto move around the Sun. These nine planets and the Sun are known as Solar System. The gravitational attraction holds all the nine planets and the Sun in the solar system.

To get the weight of the object that has mass, the gravitational acceleration should be multiplied with the mass.

There are four fundamental forces in the Universe, i.e. gravity force, weak interaction force, strong interaction force and electromagnetic force. Among these forces, gravity force is the weakest force.

konstantin123 [22]

A precipitate forms from a double displacement reaction or metathesis.

Explanation:

If given two clear solutions and upon reacting a cloudy/insoluble substance forms with the rest of the liquid being clear, a double displacement reaction has been carried out. The insoluble cloudy substance is called precipitate.

  1. the driving force for the bulk of double displacement reactions is the formation of precipitates.
  2. from careful observations, a solubility chart has been developed. If the compounds reacting are known, using the chart, a chemist can predict whether a precipitate will form or not.

1.00 g of a compound is combusted in oxygen and found to give 3.14g of CO2 and 1.29 g of H2O. From these data we can tell thatA.
lora16 [44]

Answer:

the compound contains C, H, and some other element of unknownidentity, so we can’t calculate the empirical formula

Explanation:

Mass of CO2 obtained = 3.14 g

Hence number of moles of CO2 = 3.14g/44.0 g = 0.0714 mol

The mass of the carbon in the sample = 0.0714 mol × 12.0g/mol = 0.857 g

Mass of H2O obtained = 1.29 g

Hence number of moles of H2O = 1.29g/18.0 g = 0.0717 mol

The mass of the carbon in the sample = 0.0717 mol × 1g/mol = 0.0717 g

% by mass of carbon = 0.857/1 ×100 = 85.7 %

% by mass of hydrogen = 0.0717/1 × 100 = 7.17%

Mass of carbon and hydrogen = 85.7 + 7.17 = 92.87 %

Hence, there must be an unidentified element that accounts for (100 - 92.87) = 7.13% of the compound.
