A shows the physical features of the land

Explanation:

A topographic map is a map that shows the physical features of the land area. Rivers, streams, mountains, valleys, hills and other physical features.

  • A topographic map is made up of series of contour lines.
  • The contour lines are lines that joins places of equal elevation.
  • All places on the contour lines have the same elevation.
  • Using the contour lines, we can understand the landforms in an area.
  • Other map keys are used to delineate settlement patterns, streams, churches, dams and the like.
  • Most topographic maps are used as base maps for making other maps.

Answer the questions in the table below about the shape of the phosphorus hexachloride (PCI^1_6) anion. What word or two-word ph
REY [17]

Shape of PCl₆⁻¹, is octahedral.

Hybrdisation of PCl₆⁻¹ is sp³d².

This can be seen the image attached.

The angle between phosphorous and chlorine is 90⁰C. As it has octahedral geometry.

So the answer is as follows:

Shape of PCl₆⁻¹, is octahedral.

Hybrdisation of PCl₆⁻¹ is sp³d².

The angle between phosphorous and chlorine is 90⁰C.

PLS ANSWER FAST AHAH<br><br> distilled water is a pure substance <br> true or false ?
mr Goodwill [35]

Answer:

True

Explanation:

If you see distilled water, it's a pure substance. That means that there are only water molecules in the liquid. A mixture would be a glass of water with other things dissolved inside, like one of those powders you take if you get sick or Kool-Aid.

Sometimes in lab we collect the gas formed by a chemical reaction over water (see sketch at right). This makes it easy to isolat
ad-work [718]

Answer:

The correct answer is 0.00582 grams.

Explanation:

In order to solve the question, let us consider the vapor pressure of H2O, as hydrogen gas is collected over water, therefore, we have to consider the vapor pressure of water in the given case. Let us assume that the pressure is 760 torr or 1 atm.

It is known that the vapor pressure of water at 40 degree C is 53.365 torr (Based on the data).

Therefore, the pressure of H2 will be,

P = 760-55.365 = 704.635 torr or 704.635/760 = 0.9272 atm

The volume of the hydrogen gas collected in the tube is 80 ml or 0.08 L

Temperature in Kelvin will be 40+273 = 313 K

To calculate the moles of hydrogen (H2) gas, there is a need to use the ideal gas equation, that is, PV= nRT, in this R is the gas constant, whose value is 0.0821 L atm/molK, and n is the moles of the gas.

By inserting the values in the equation we get:

PV = nRT

n = PV/RT = 0.9272 *0.08 / 0.0821 * 313

n = 0.00289 moles

The mass of H2 will be moles * molar mass = 0.00289 * 2.016

= 0.00582 grams.
