Answer:
CO2
Explanation:
(I Just took the test)
At STP 1 mol=22.4 Liters, so we now know that it is asking for which of the gasses has a molar mass of 44, and CO2 is th only one with that molar mass
The balanced reaction
is:
AgNO3 + NaCl = NaNO3 + AgCl
<span>We are given the amount of silver nitrate to react with sodium chloride. This
will be our starting point.</span>
15.0 mol AgNO3 (1 mol AgCl / 1
mol AgNO3 ) =15.0 mol AgCl
The amount of moles produced is the same with the amount of the given reactant since they only one is to one ratio.
I would say d. average of the mass number and the atomic number for the element.
Organic: sugar
inorganic: salt
<span>Dalton's atomic theory originally has 5 postulates. Among the choices, there are three that are included. These are:
*atoms of one element cannot change into atoms of another element.
</span><span>*each element is composed of tiny, indestructible particles called atoms.
</span><span>*atoms combine in simple, whole number ratios to form compounds
The others are incorrect. Atoms of one element cannot change to another element. Atoms of the same element do not have the same mass because they can occur as isotopes. Nuclear particles are not part of Dalton's theory, just the chemical reactions.</span>
