How many atoms of phosphorus are in 7.00 mol of copper(II) phosphate?
Rama09 [41]

<u>Answer:</u> The number of phosphorus atoms in given amount of copper(II) phosphate is 8.431\times 10^{24}

<u>Explanation:</u>

We are given:

Moles of copper(II) phosphate Cu_3(PO_4)_2 = 7.00 mol

1 mole of copper(II) phosphate contains 3 moles of copper, 2 moles of phosphorus and 8 moles of oxygen atoms

Moles of phosphorus in copper(II) phosphate = (2\times 7.00mol

According to the mole concept:

1 mole of a compound contains 6.022\times 10^{23} number of particles

So, 7.00 moles of copper(II) phosphate will contain = (2\times 7\times 6.022\times 10^{23}=8.431\times 10^{24} number of phosphorus atoms.

Hence, the number of phosphorus atoms in given amount of copper(II) phosphate is 8.431\times 10^{24}

How many moles of sulfur trioxide are formed from 3 moles of oxygen using the given
fiasKO [112]

Answer:

6 moles of SO₃ formed.

Explanation:

Given data:

Number of moles of SO₃ formed = ?

Number of moles of oxygen react = 3 mol

Solution:

Chemical equation;

2SO₂+ O₂      →   2SO₃

now we will compare the moles of oxygen and sulfur trioxide.

                             O₂            :            SO₃

                               1             :             2

                               3            :           2/1×3 = 6 moles

Thus, six moles of SO₃ will formed.

xenn [34]

Answer:

See the complete question and the answer below

Explanation:

Sam and joe are trying to determine whether their ideas are scientific or pseudoscientific. sam's idea is not rejected when experiments produce different results. joe's idea gives the same result when tested repeatedly.  which statement is correct about sam and joe's idea?

<em>both ideas could be scientific. </em>

<em>neither idea could be scientific. </em>

<em>only sam's idea could be scientific. </em>

<em>only joe's idea could be scientific.</em>

<em />

The correct answer here would be that both ideas could scientific.

Scientific ideas are those that hold true or not rejected after being tested by different experiments. Pseudoscientific ideas cannot hold true after being tested by experiments.

If an idea is tested by repeated experiments and the experiments produce different results, the idea might remain unrejected if there are no overwhelming evidence to do so from the experiments. That an idea remains unrejected due to inadequate experimental evidence, however, does not mean it is scientific or unscientific.

In the same vein, that a repeatedly tested idea gives the same results does not mean that the idea is scientific unless the results say so. If results repeatedly go against the idea, it means such an idea is unscientific or pseudoscientific.

<em>Hence, both Joe and Sam's idea could be scientific, provided further experimental investigations are carried out.</em>
