The independent variable is the one we are changing in the experiment. As we change it, the dependent variable might also change.

C. the density of the rock because we are changing the density of the rock and seeing how all other variables change with regards to the density.

How many grams are in 0.220 mol of Ne?
kumpel [21]

Answer:

4.44 g Ne

General Formulas and Concepts:

<u>Chemistry - Atomic Structure</u>

  • Reading a Periodic Table
  • Using Dimensional Analysis

Explanation:

<u>Step 1: Define</u>

0.220 mol Ne

<u>Step 2: Identify Conversions</u>

Molar Mass of Ne - 20.18 g/mol

<u>Step 3: Convert</u>

<u />0.220 \ mol \ Ne(\frac{20.18 \ g \ Ne}{1 \ mol \ Ne} ) = 4.4396 g Ne

<u>Step 4: Check</u>

<em>We are given 3 sig figs. Follow sig fig rules and round.</em>

4.4396 g Ne ≈ 4.44 g Ne

When substances react chemically to create a new substance, will that new substance have the same physical and chemical properti
Makovka662 [10]

Answer:

When a chemical reaction occur, new substances are formed. The physical and chemical properties of new substances are different from initial substance.

Explanation:

Chemical change:

The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.

These changes are irreversible.

These changes occur due to chemical reactions.

These may not be observed with naked eye.

Examples:

Combustion of fuel or wood: that oil or wood convert into energy, CO2 and ash in case of wood .

Boiling of egg: that change the chemical composition of protein in the egg.

Physical change:

The changes that occur only due to change in shape or form but their chemical or internal composition remain unchanged.

These changes were reversible.

They have same chemical property.

These changes can be observed with naked eye.

Examples:

Water converting to Ice.

Water converting to gas.

In this water molecule remain the same only they rearrange themselves that change its state of mater not composition.

The general formula for the alkyne series is:<br> CnH2n+2<br> CnH2n<br> CnH2n-2<br> CnHn+2
jeyben [28]
The general  formula  for  alkyne  series  is     CnH2n-2

 This is because alkyne  is unsaturated  hydrocarbon   which has  one  triple  bond   and   has  no functional  group  from   homologous series. Alkyne  has  a  general formula of  CnH2n-2

An  example  of an  alkyne  in  ethyne    with HC≡CH  chemical formula ,

another example is propyne   with  CH3C≡CH  formula
