Answer:

Explanation:

Specifically, what do we mean when we say that a scientific hypothesis must be testable? It must be able to be proven wrong. ... A scientific fact is something that observers can observe and agree to be true. A hypothesis is an educated guess that answers a question.

A compound is isolated from the rind of lemons that is found to be 88.14% carbon and 11.86% hydrogen by mass how many moles of c
11111nata11111 [884]
Lets assume that 100 grams of the compound are present.

Carbon mass: 88.14 g
Hydrogen mass: 11.86 g

Moles carbon: 88.14/12 = 7.34
Moles hydrogen: 11.86/1 = 11.86

The moles of carbon are 7.34 and the moles of hydrogen are 11.86.

<h2>2000 N</h2>

Explanation:

The work done by an object can be found by using the formula

workdone = force × distance

From the question we have

workdone = 500 × 4

We have the final answer as

<h3>2000 N</h3>

Compare 1 mole of H2, 1 mole of O2 and 1 mole of F2
likoan [24]

Explanation:

(a)  As per the mole concept, one mole of any atom contains 6.022 \times 10^{23} atoms or molecules, that is, Avogadro's number of atoms.

Therefore, 1 mole of H_{2} = 2 \times 6.022 \times 10^{23} molecules

                                           = 1.2044 \times 10^{23} molecules

   1 mole of O_{2} = 2 \times 6.022 \times 10^{23} molecules

                                    = 1.2044 \times 10^{23} molecules

   1 mole of F_{2} = 2 \times 6.022 \times 10^{23} molecules

                                    = 1.2044 \times 10^{23} molecules

Hence, there are equal number of molecules present in the given atoms.

(b)   Mass of each given atom will be calculated as follows.

                Mass = no. of moles × molar mass

As one molecule of H_{2} contains 2 atoms of hydrogen.

So, mass of 1 mole of H_{2} = 2 mol \times 1.008 g/mol

                                                     = 2.016 g

      mass of 1 mole of O_{2} = 2 mol \times 15.999 g/mol

                                                     = 31.996 g

      mass of 1 mole of F_{2} = 2 mol \times 18.998 g/mol

                                                     = 37.996 g

Thus, we can conclude that F_{2} has the greatest mass.
