If the reacted oxygen is 35.1 g.
H2O mass= (35.1+9.8)-29.6
= 19.3g
Answer:
Explanation:
The two carbon atoms would be different. These different carbon isotopes are called isotopes. Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass number due to the difference in the number of neutrons in their various nuclei.
Carbon for example has 3 known isotopes which are:
¹²₆C ¹³₆C ¹⁴₆C
These isotopes have different places in nature where they can be found. Some can occur together naturally.
Isotopes have the same chemical properties because they share similar electronic configuration.
Answer:
I <em>believe</em> it is Avogadro's number: 6.022 × 10²³
Explanation:
One mole of a substance is equal to 6.022 × 10²³ units of that substance
Balanced chemical equation for the reaction is:
2S
(g) +
(g)+ 2
O (l) ⇒
Moles of
formed is 5.75 moles.
Moles of oxygen used is 5.75 moles in the reaction.
Explanation:
Data given:
moles of S
= 11.5 moles
moles of
= ?
Moles of
needed =?
balanced equation with states of matter =?
Balanced chemical reaction under STP condition is given as:
2S
(g) +
(g) + 2
O (l) ⇒
From the balanced reaction 2 moles of sulphur dioxide reacted to form 1 mole of sulphuric acid:
so, from 11.5 moles of S
, x moles of
is formed

2x = 11.5
x = 5.75 moles of sulphuric acid formed.
From the balanced reaction 1 mole of oxygen reacted to form 1 mole of sulphuric acid.
when 11.5 moles of Sulphur dioxide reacted then oxygen in the reaction is 5.75 moles.
Benthos are "organisms inhabiting the seafloor" according to one source, so I would say the answer is C.
