Explanation:
i may be wrong, but i believe its carbon dioxide
Answer:
1. 12.18g of N2H4.
2. 62.24g of N2H4
3. 87.23g of N2
Explanation:
N2 + 2H2 —> N2H4
Molar Mass of N2 = 2x14 =28g/mol
Molar Mass of N2H4 = (2x14) + (1x4) = 28 + 4 = 32g/mol
Molar Mass of H2 = 2x1 = 2g /mol
Mass conc of H2 from the balanced equation = 2 x 2 = 4g
1. From the balanced equation,
28g of N2 produced 32g N2H4.
Therefore, 10.66 g of N2 will produce = (10.66x32)/28 = 12.18g of N2H4.
2. From the balanced equation,
4g of H2 produced 32g of N2H4.
Therefore, 7.78 g of H2 will produce = (7.78x32)/4 = 62.24g of N2H4
3. From the balanced equation,
28g of N2 produced 32g N2H4.
Therefore, Xg of N2 will produce 99.69 g of N2H4 i.e
Xg of N2 = (28x99.69)/32 = 87.23g
The dominant species present in water if the ph is held constant at ph = 8 is .
<h3>What is ph?</h3>
The pH scale is used in chemistry to determine whether an aqueous solution is basic or acidic. Historically, pH stood for "potential of hydrogen." The pH values of acidic solutions are typically lower than those of basic or alkaline solutions.
A solution's pH is a significant indicator of its chemical composition. The pH can affect how readily available nutrients are, how biological processes work, how bacteria behave, and how chemicals behave. The negative log base 10 of the hydronium concentration is used to define pH. The pH is a logarithmic indicator of how many hydrogen ions are present in a solution. Since pH is measured on a log scale, a pH increase of 1 equates to a 10x increase in the concentration of H+ ions.

The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
