Answer:
Search by reactants (P 2O 5, H 2O) and by products (H 3PO 4)
H2O + P2O5 → H3PO4
H2O + HNO3 + P2O5 → H3PO4 + N2O5
Answer:
a element
Explanation:
In science copper is a element. It is one of the transition metals found on the periodic table of elements.
Elements are distinct substances that cannot be split-up into simpler substances. Such substances consist of one kind of atom.
There are over a hundred elements that are known till date.
Each elements combines to form a compound
fibrous roots; taproots
Explanation:
A taproot root consists of one large main root with smaller roots that branches off into the soil, while the fibrous roots consists of several main roots that branches off to form one mass of roots.
- The root system in plants helps them to absorb water and other nutrients from the soil.
- A taproot is much more like extension of stem that penetrates into the ground.
- It tapers at the end with many other smaller roots branching and networking from it.
- The fibrous root is a series of roots directly from the stem that independent of one another.
- Roots are used by plants for anchorage into the soil.

3Na2O(at) + 2Al(NO3)3(aq) —> 6NaNO3(aq) + Al2O3(s)
This is a double replacement reaction and NaNO3 is aqueous because Na is an alkali metal, plus nitrate is in the solution. Both of these are soluble. Al2O3 is not soluble because it does not contain any element that is soluble and is hence the precipitate.
Hope this helped!
