  • The units used for mass were kilogram (kg)
  • The units used for volume were cubic metres (m³)
  • The units used for density were kilogram per cubic metres (kg/m3).

When carrying out a research or experiment in a laboratory, your data should be recorded using standard units.

These units are called S.I. units or International system of units. They are the globally-agreed system of measurement units.

The properties of an object with its SI unit include:

  • Mass: This is the quantity of matter that is found in an object which is always constant. The SI unit of mass is Kilogram (kg).
  • Volume: This measures the space occupied by an object. The SI unit of volume is cubic metres (m³).
  • Density: This is mass of a unit volume of an object. The SI unit of density is kilogram per cubic metres (kg/m3).

Which atom absorbs more energy, one in which an electron moves from the second shell to the third shell or an otherwise identica
Assoli18 [71]

Answer:

identical atom in which an electron moves from the first to the third shell.

Atoms may occupy different energy states. The energy states are discrete, i.e. they occur at specific values only. Therefore an atom can only move to a new energy level if it absorbs or emits an amount of energy that exactly corresponds to the difference between two energy levels.

The lowest possible energy level that the atom can occupy is called the ground state. This is the energy state that would be considered normal for the atom.

An excited state is an energy level of an atom, ion, or molecule in which an electron is at a higher energy level than its ground state.

An electron is normally in its ground state, the lowest energy state available. After absorbing energy, it may jump from the ground state to a higher energy level, called an excited state.

Dehydrohalogenation of 1-chloro-1-methylcyclopropane affords two alkenes (A and B) as products.
UNO [17]

Explanation:

Dehydrohalogenation reactions occurs as elimination reactions through the following mechanism:

Step 1: A strong base(usually KOH) removes a slightly acidic hydrogen proton from the alkyl halide.

Step 2: The electrons from the broken hydrogen‐carbon bond are attracted toward the slightly positive carbon (carbocation) atom attached to the chlorine atom. As these electrons approach the second carbon, the halogen atom breaks free.

However, elimination will be slower in the exit of Hydrogen atom at the C2 and C3 because of the steric hindrance by the methyl group.

Elimination of the hydrogen from the methyl group is easier.

Thus, the major product will A

A mixture of so2(g) and o2(g), formed by the complete decomposition of so3(g), is collected over water at 34°c at a total pressu
Sedbober [7]
The decomposition of so3 to so2 gas and o2 gas can be described in the balanced chemical equation: 

2so3(g) = 2 so2 (g) + 02(g). 

so assuming a complete reaction, the ratio of so2 gas to total products is 2/3 while that of 02 is 1/3. 

Subtracting water's water vapor pressure, 760-40 mm hG = 720 mm Hg.

then the products partial pressures are

so2 = 2/3 * (720) = 480 mm Hg.
o2 = 720-480 = 240 mm Hg.

Look at this data and calculate the mean, median, mode, and range.
CaHeK987 [17]

Answer:

the median is 14 the range is 15 the mode is 14 and the mean is 12.7

Explanation:

for the median you put all numbers is order but least to greatest and figure out the middle number for range you take the smallest and the biggest number and subtract them for mode you use the most repeated number and for the mean you add all the numbers and divide by the total of numbers I hope this helped
