<span>When silver nitrate reacts with sodium chloride, it produces silver chloride and sodium nitrate. The chemical reactions contains a one to one ratio of each compound on the reactant side and the products side.
In order to determine the correct answer, we must first convert the 25.0 milliliters to moles using:
moles = concentration * volume.
25 ml = 0.025 L
Moles of both reactants = 0.25 * 1 = 0.025
Now we have to calculate the mass of AgCl which is found by adding the atomic weight of silver and chlorine. The mass of AgCl is 143.3 g/mol. Multiplying 143.3 g/mol by 0.025 moles results in a mass of 3.58 grams of AgCl being produced.</span>
Answer:Calcium atoms have smaller radii than potassium atoms since calcium atoms have a greater nuclear charge.
Explanation:
Answer:
(a) 0.2518 g; (b) 6
Explanation:
The Law of Multiple Proportions states that when two elements A and B combine to form two or more compounds, the masses of B that combine with a given mass of A are in the ratios of small whole numbers.
That is, if one compound has a ratio r₁ and the other has a ratio r₂, the ratio of the ratios r is in small whole numbers.
(a) Methane and ethane
In methane, the mass ratio of H:C is r₁ = 0.3357:1.00.
In ethane, the mass ratio of H:C is r₂
The ratio of the ratios r = ⁴/₃
r = r₁/r₂
⁴/₃ = 0.3357/r₂
(⁴/₃)r₂ = 0.3357
r₂ = 0.3357 × ¾ = 0.2518:1
Ethane contains 0.2518 g of H for every 1 g of C.
(b) Xenon fluorides
In XeF₂, the mass ratio of F:Xe is r₁ = 0.2894:1
In XeFₙ, the mass ratio of F:Xe is r₂ = 0.8682:1
r = r₂/r₁ = 0.8682/0.2894 = 3.000:1 ≈ 3:1
XeFₙ contains three times as many F atoms as XeF₂.
n = 6
Answer: Yes , in , two electrons from magnesium are transferred to chlorine atoms.
Explanation:
Ionic compound is formed by the transfer of electrons. For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
For example : For formation of
Electronic configuration of magnesium:
Magnesium atom will loose two electrons to gain noble gas configuration and form magnesium cation with +2 charge.
Electronic configuration of chlorine:
Chlorine atom will gain one electron to gain noble gas configuration and form chloride ion with -1 charge.
In Magnesium chloride two electrons from magnesium metal gets transferred to two chlorine atoms and thus is formed.
