Answer:

there are two types of nomenclature used in organic system. the most widely used and universally accepted system of nomenclature is the IUPAC system of nomenclature. some compounds are referred to by their common name that existed before the IUPAC system or is more widely known than the IUPAC names.

Explanation:

IUPAC ( international union of pure and applied chemistry) system of nomenclature is used to name compounds in organic system. there are some principles to be followed while using this nomenclature. some of them are:-

1) identification of parent chain is the first step. the longest hydrocarbon chain is the parent chain.

2) identification of all the substituent groups of the parent chain is also required.

3) hydrocarbon cyclic ring has a fixed prefix and that is cyclo.

S(s)+3F2(g)->SF6(g) how many mol of F2 are required to react completely with 2.30 mol of S?

Brilliant_brown [7]

Answer: There are 6.9 mol of $F_{2}$ are required to react completely with 2.30 mol of S.

Explanation:

The given reaction equation is as follows.

$S(s) + 3F_{2}(g) \rightarrow SF_{6}(g)$

Here, 1 mole of S is reaction with 3 moles of $F_{2}$ which means 1 mole of S requires 3 moles of $F_{2}$ .

Therefore, moles of $F_{2}$ required to react completely with 2.30 moles S are calculated as follows.

$1 mol S = 3 mol F_{2}\\2.30 mol S = 3 mol F_{2} \times 2.30 \\= 6.9 mol F_{2}$

Thus, we can conclude that there are 6.9 mol of $F_{2}$ are required to react completely with 2.30 mol of S.

What is an experimental control

attashe74 [19]

The experimental control is the standard used as a comparison for the experimental groups.

For example, you may be trying to find out how different types of disinfectants affect bacterial growth. The control group would receive <em>no</em> disinfectant whereas the experimental groups would be the ones on which the disinfectants were tested.

Hope this makes sense!

How many moles of tungsten (W,183.85 g/lol are in 415 grams of tungsten?

vladimir1956 [14]

Given mass of tungsten, W = 415 g

Molar mass of tungsten, W = 183.85 g/mol

Calculating moles of tungsten from mass and molar mass:

$415 g * \frac{1 mol}{183.85 g} = 2.26 mol W$

A balloon contains 11.1 g of nitrogen monoxide gas (NO). how many molecules are in the balloon?

grandymaker [24]

The number of molecules that are in balloon are = 2.227 x10^23 molecules

<h3> calculation</h3>

calculate the number of moles of NO

moles = mass/molar mass

molar mass of NO = 14+ 16 = 30 g/mol

moles is therefore= 11.1 g/30g/mol= 0.37 moles

by use of Avogadro's constant that is

1 mole= 6.02 x10^23 molecules

0.37 =? molecules

=(6.02 x10^23 x 0.37 moles)/ 1mole=2.227 x10^23 molecules
