The following chemical reaction takes place in aqueous solution: SnSO 4 (aq)+2 NaOH(aq) Sn(OH) 2 (s)+Na 2 SO 4 (aq) Write the net tonic equation for this reaction.
The net ionic equation for the reaction between SnSO₄ and NaOH is:
Sn²⁺(aq) + 2OH¯(aq) —> Sn(OH)₂(s)We'll begin by writing the dissociation equation for SnSO₄ and NaOH.
SnSO₄(aq) —> Sn²⁺(aq) + SO₄²¯(aq)
NaOH(aq) —> Na⁺(aq) + OH¯(aq)
In solution, the reaction will proceed as follow:
SnSO₄(aq) + NaOH(aq) —>
Sn²⁺(aq) + SO₄²¯(aq) + Na⁺(aq) + OH¯(aq) —> Sn(OH)₂(s) + Na⁺(aq) + SO₄²¯(aq)
Cancel the spectator ions (i.e Na⁺ and SO₄²¯) and write 2 before OH¯ to obtain the net ionic equation.
Sn²⁺(aq) + 2OH¯(aq) —> Sn(OH)₂(s)

How many grams are in 4.3 x 10 -4 moles of calcium phosphate?
Explanation:
Ca3(PO4)2 1 mole has 310.2 g
Ca3(PO4)2 4.3 × 10^-4 moles has 4.3 × 10^-4 × 310.2
= 1,333.86 × 10^-4
= 1.334 × 10^-1
OR 0.1334 g
What is the diffrence between organic and inorganic compounds?
Answer:
D. Organic compounds contain carbon and inorganic compounds do not.
Explanation:
Explain in terms of atomic structure, why cesium has a lower first ionization energy than rubidium. Determine the family/group in which each element is located
Answer:
Explain in terms of atomic structure, why Cesium (Cs) has a LOWER first ionization energy than Rubidium (Rb). Cesium is further down on the periodic table. ... The ion K+1 has one more electron than the atom K. K+1 has lost one electron from its valence shell, and therefore has one less electron shell than K.
Explanation:
Radium contains the most electron shells, which creates a shielding effect that reduces the ionization energy.
Radium:
[tex][Rn]7 S^2[/tex] Layer atomic radiusCalcium:
[tex][Ar]4S^2[/tex] Smaller atomic radiusA higher proportion of electron shells creates a shielding effect, resulting throughout a decreased zeff as well as easier ionization of the outermost election.

How many mg of metallic ions are in 1.0 mL of 0.10 M LINO3
Answer:
0.6941 mg
Explanation:
First we calculate how many LiNO₃ moles there are, using the given concentration and volume:
1.0 mL * 0.10 M = 0.10 mmol LiNO₃As 1 mol of LiNO₃ contains 1 mol of Li, in the problem solution there are 0.10 mmol of Li (the only metallic ion present).
Now we convert Li milimoles into miligrams, using its atomic mass:
0.10 mmol Li * 6.941 mg/mmol = 0.6941 mgWhat happens when
an element is
oxidised?
Answer:
The process in which a substance loses an electron in a chemical reaction is called oxidation. The atoms that lost electrons are said to be oxidized. Atoms can be oxidized by nonmetals. Reduction is gain of electrons and thus gaining of negative charge.

What is percent composition by mass?
Percent composition indicates the relative amounts of each element in a compound. For each element, the mass percent formula is: % mass = (mass of element in 1 mole of the compound) / (molar mass of the compound) x 100% or. mass percent = (mass of solute / mass of solution) x 100%.

Fe and O2 = 0 mol
Fe2O3 = 1 mol
Further explanationGiven
2 mol Fe
48 g O

= 48 g : 32 g/mol
= 1.5 moles
Limiting reactants :
Fe : O2 = 2/4 : 1.5/3 = 0.5 : 0.5
Both reactants have completely reacted

The atomic number of an element configuration 2,8, 8,2,13
Answer:
33
Explanation:
The atomic number of an element configuration 2,8, 8,2,13 is 33.
The electron configuration is defined as the arrangement of electrons in atomic or molecular orbitals of an atom. The sum of electrons in different orbitals shown in the electron configuration represents the atomic number of the atom.
So, atomic number of the element configuration 2,8, 8,2,13 is 33.
An atom or ion has 43 neutrons , 36 protons, and 36 electrons. Identify the element symbol, and determine the mass number and charge for this atom or ion.
Answer:
Element name: Krypton
Symbol: Kr
Mass Number: 79 AMU
Charge: 0, electrons and protons cancel out.
ion: none, it is a halogen.
Explanation:
Krypton is the 36th element on the periodic table and has 36 protons. The mass is protons plus nuetrons so 36 + 43 is 79 AMU or Atomic Mass Units.

According to VSEPR theory what causes molecular shapes to form?
A: The attraction of electrons and protons
B: The attraction of protons and neutrons
C: The repulsion of electrons and electrons
D: The repulsion of protons and protons
Answer:
C: the repulsion of electrons and electrons.
Explanation:
According to the VSEPR theory, molecular shapes adjust so that the electrons can be as far apart as possible due to electrons repelling each other, which would mean the only possible answer is C.
Paul went to his friend's 2 km from his house, he used his bike and took him 9 minutes.
Paul and his friend rode another 1.5 km to get some ice cream, it took them 10 minutes.
What was Paul's average speed of the whole trip?
The average speed : 3.07 m/s
Further explanationGiven
d1 = 2 km
t1 = 9 min
d2 = 1.5 km
t2 = 10 min
Required
The average speed
Solution
Average speed = total distance : total time
total distance :
= d1+d2
= 2+1.5
=3.5 km
total time :
= t1+t2
= 9 min + 10 min
= 19 min
Average speed :
= 3.5 km : 19 min
= 0.184 km/min
= 3.07 m/s
