when 48 .0g of carbon reacts with oxygen gas to form carbon dioxide, no carbon or oxygen is left over. How much oxygen is reacte

Arte-miy333 [17]

Answer:

128g

Explanation:

Given parameters:

Mass of carbon = 48g

Mass of carbon dioxide = 176g

Unknown:

Mass of oxygen that reacted = ?

Solution:

Every chemical reaction must obey the law of conservation of mass. It states that "in a chemical reaction, matter is neither created nor destroyed" .

So;

Mass of carbon + Mass of oxygen = Mass of carbon dioxide

Mass of oxygen = Mass of carbon dioxide - Mass of carbon

Mass of oxygen = 176 - 48 = 128g

A. What is the pH of a solution with a [H+] of 6.8 x 10^-11?

inysia [295]

Answer:

[H+] = 6.8×10^-11

so, pH = - log[H+]

= - log [6.8×10^-11]

= -(-10.167)

= 10.167

O2- is the Lewis ______ in the following reaction

matrenka [14]

$O^{2-}$ is the Lewis base in the following reaction:

$SO_3(g) + O^{2-}(aq)$ → $SO_4^{2-}(aq)$

<h3>What is lewis base? </h3>

Lewis base is a species that donates an electron pair.

In the above-given chemical equation, the $O^{2-}$ is the lewis base which is donating an electron pair to the central atom of $SO_3$ to form $SO_4^{-2}$ .

Hence, $O^{2-}$ is the Lewis base in the following reaction:

$SO_3(g) + O^{2-}(aq)$ → $SO_4^{2-}(aq)$
