Answer:

Explanation:

1)

H₂SO₄:

Element (symbol)     No of atoms in         No of compounds        Total atoms

                                    1 molecule                   coefficient

H                                              2                            1                                 2

S                                               1                                                                1

O                                              4                                                               4

2)

2H₃PO₄:

Element (symbol)     No of atoms in         No of compounds        Total atoms

                                    1 molecule                   coefficient

H                                              3                            2                                 6

P                                               1                                                                2

O                                              4                                                                8

There are two mole of H₃PO₄. One mole contain 3 hydrogen atom, 1 phosphorus atom and 4 oxygen atoms. Thus in two mole of compound 6 hydrogen atoms, 2 phosphorus atom and 8 oxygen atoms are present.

An oxidation-reduction reaction that is also a synthesis reaction
Aleonysh [2.5K]

The example of a chemical combination that can also be said to be a synthesis reaction is; 2Mg(s) +O_{2} (g) -- > 2 MgO(s)

<h3>What is a synthesis reaction?</h3>

We know that the meaning of the synthesis reaction is quite central as we attempt to answer the question that is lying right before us here. If we are talking about the synthesis reaction then our mind must have to go to the kind of reaction in which there is the combination of two or more so as to produce a single compound.

As we are talking about the synthesis reaction, we would have to look at the reaction that would give rise to a single product as it has been written. Let us also recall that we have been told that the reaction is a  oxidation-reduction reaction thus there is a change in oxidation number in the process of the reaction as shown.

The most unusual characteristic of Uranus is _____.
fiasKO [112]

Answer:

the axis is tilted at 98 degrees

Explanation:

Uranus is blue, not green; it has an atmosphere of hydrogen and helium, not methane.  While it does have an icy cold temperature, that's not a very unusual characteristic for an outer planet.  However, the tilt of the axis is unusual; no other planet is tilted almost completely on its side!

In general, what is the effect if increased temperature on the solubility of a gas
r-ruslan [8.4K]

Increased temperature causes an increase in kinetic energy. The higher kinetic energy causes more motion in the gas molecules which break intermolecular bonds and escape from solution.
