Answer:
90 Thymine bases
Explanation:
Chargaff's rules states that in the DNA of any organism, the amount of purine and pyrimidine bases must be in a 1:1 ratio. This means that the amount of Adenine and Guanine bases (purines) should be equal with their complementary pairs of Thymine and Cytosine bases respectively (pyrimidines). (A = T) + (G = C) = 100
Hence, according to this question, if there are 60 cytosine bases, this means that there will be 60 Guanine bases. 60 C + 60 G = 120 pyrimidines
300 total bases - 120 pyrimidine bases = 180 purine bases.
180/2 = 90 equal bases of Adenine and Thymine. Hence, Thymine bases will be 90.

This is the balanced equation for a double-displacement reaction
Al2(SO4)3+Mg(NO3)2⟶ What would be the product(s) of this reaction? *These are NOT balanced, just look for the correct products*
Answer:
[tex]Al_2(SO_4)_3+3Mg(NO_3)_2\rightarrow 2Al(NO_3)_3+3MgSO_4[/tex]
Explanation:
Hello there!
In this case, for the given reactants side, we infer this is a double replacement reaction because all the cations and anions are switched around as a result of the chemical change, we infer that the products side include aluminum with nitrate and magnesium with sulfate as shown below:
[tex]Al_2(SO_4)_3+Mg(NO_3)_2\rightarrow Al(NO_3)_3+MgSO_4[/tex]
However, we need to balance since unequal number of atoms are present at both sides, thus, we do that as shown below:
[tex]Al_2(SO_4)_3+3Mg(NO_3)_2\rightarrow 2Al(NO_3)_3+3MgSO_4[/tex]
Thus, we make 6 Al atoms, 3 S atoms, 3 Mg atoms and 30 O atoms on each side in agreement with the law of conservation of mass.

If 8.51×10-2 moles of SO3(g), 0.210 moles of SO2, and 0.354 moles of O2 are at equilibrium in a 15.4 L container at 1.25×103 K, the value of the equilibrium constant, K, is ____
Answer: The value of equilibrium constant, K, is [tex]7.74 \times 10^{-4}[/tex].
Explanation:
The reaction equation is as follows.
[tex]2SO_{3}(g) \rightleftharpoons 2SO_{2}(g) + O_{2}(g)[/tex]
Now, the expression for equilibrium constant of this reaction is as follows.
[tex]K = \frac{[SO_{2}]^{2}[O_{2}]}{[SO_{3}]^{2}}[/tex]
Substitute the given values into above expression as follows.
[tex]K = \frac{[SO_{2}]^{2}[O_{2}]}{[SO_{3}]^{2}}\\= \frac{(\frac{0.210}{15.4})^{2} \times (\frac{0.354}{15.4})}{(\frac{8.51 \times 10^{-2}}{15.4})}\\= 7.74 \times 10^{-4}[/tex]
Thus, we can conclude that the value of equilibrium constant, K, is [tex]7.74 \times 10^{-4}[/tex].

balance the equation xcl2(aq)+agno3(aq)=x(no3)2(aq)+agcl(s)
Explanation:
[tex]XCl _{2(aq)} + 2AgNO _{3(aq)}→X(NO _{3}) _{2(aq)} +2 AgCl _{(s)}[/tex]
Answer:
[tex]XCl2(aq) + 2AgNO3(aq) --------> X(NO3)2(aq) + 2AgCl(s)[/tex]
Explanation:
The rule guiding he balancing of reaction equations is that the number of atoms of each element on both sides of the reaction equation must be the same.
In order to balance this equation, this rule must be applied. The balanced reaction equation therefore becomes;
XCl2(aq) + 2AgNO3(aq) --------> X(NO3)2(aq) + 2AgCl(s)
We can see by conducting an atom count that the number of atoms of each element on both sides of reaction equation is the same hence the equation is balanced.

A student wants to reclaim the iron from an 18.0 gram sample of iron (III) oxide, which occurs according to the reaction below: how many grams of iron can be reclaimed.
Answer:
12.6 g
Explanation:
Step 1: Write the balanced decomposition reaction
2 Fe₂O₃ ⇒ 4 Fe + 3 O₂
Step 2: Calculate the moles corresponding to 18.0 g of Fe₂O₃
The molar mass of Fe₂O₃ is 159.69 g/mol.
18.0 g × 1 mol/159.69 g = 0.113 mol
Step 3: Calculate the moles of Fe formed from 0.113 moles of Fe₂O₃
The molar ratio of Fe₂O₃ to Fe is 2:4. The moles of Fe formed are 4/2 × 0.113 mol = 0.226 mol
Step 4: Calculate the mass corresponding to 0.226 moles of Fe
The molar mass of Fe is 55.85 g/mol.
0.226 mol × 55.85 g/mol = 12.6 g
When there is an increase in temperature of a gas in an
enclosed container, the pressure will also increase due to the:
Answer:increase In kinetic energy of molecules
Explanation:increase in kinetic energy of molecules
When there is an increase in temperature of a gas in an enclosed container, the pressure will also increase due to the increase in the kinetic energy.
What is the relation between temperature and pressure?Temperature and pressure of gas is directly proportional to each other.
When the temperature of the gas increases, then the kinetic energy of the gas molecules are also increases. Due to increase in the velocity of gas molecules they will collide with each other as a result of which pressure of the gas is aslo increases.
Hence due to increase in kinetic energy, pressure increases.

why is mn2+ more stable than mn3+
Answer:
See Explanation
Explanation:
Let us closely consider the electronic configuration of manganese atom, Manganese II ion and manganese III ion. This will give a clue of the answer.
Manganese: [Ar] 3d5 4s2
Manganese II: [Ar] 3d5
Manganese III: [Ar] 3d4
Now, let us remember that the d orbital contains a maximum of ten electrons. Hence, the electronic configuration of Mn^2+, [Ar] 3d5 reflects a half filled d- orbital which is known to be unusually stable(half-filled orbitals are known to possess unusual stability just as fully filled orbitals do).
The same can not be said about Mn^3+. Hence, Mn^2+ is more stable than Mn^3+.

State the trend in chemical reactivity as we go down the group for Group I elements Account for
this trend using the electronic structures of the elements.
Answer: The reactivity of group 1 elements increases as you go down the group because: the atoms become larger. the outer electron becomes further from the nucleus. the force of attraction between the nucleus and the outer electron decreases.
A container of oxygen with a volume of 60 L is heated from 300 K to 400 k, What is the new volume?
Answer:
80L
Explanation:
V1/T1 = V2/T2
V2 = V1 T2/T1
T1 = 300K
V1 = 60L
T2 = 400K
V2 = ?
V2 = V1 T2/T1
V2 = (60L)(400K) / (300K)

Why is it appropriate to describe the Sun and its orbiting celestial bodies as a system?
As the bodies present in the gravitational force of sun, so it is appropriate to describe the sun and its celestial bodies as system.
What are celestial bodied?Celestial bodies are those objects which are present in the space not in the land.
In the space all the planets are present in their orbitals under the gravitational force of the sun and do the motion around the sun, because of that force planets are present in the orderly arrangement. Because of the revolution of the earth around the sun, seasons will change on the earth.
Hence, it is appropriate to describe the sun and its celestial bodies as system.
