(25 POINTS AND BRAINLIEST)What is the volume of 2 mol of chlorine gas at STP?
2.0 L
11.2 L
22.4 L
44.8 L
Answer:
44.8
Explanation:
According to standard temperature and pressure and ideal gas equation , the volume of 2 mole of chlorine gas at STP is 44.8 liters.
What are standard temperature and pressure conditions?Standard temperature and pressure are defined as a standard set of conditions required for experimental measurements which are established to allow comparison between different sets of data.
Standards which are commonly used are those International Union of pure and applied chemistry and national institute of standards and technology.These are not universally accepted standards but are the ones which are commonly used.
Standard conditions of pressure and temperature are necessary to define standard reference conditions used to express volumes of liquids and gases.
These values are important to physicists, chemists ,engineers ,pilots and navigators.On substituting values in ideal gas equation, volume= 2×8.314×273/1=44.8 liters.
Thus, the volume of 2 mole of chlorine gas at STP is 44.8 liters.

Lithium and magnesium bromide react to produce lithium bromide and magnesium metal
Answer: [tex]2Li+MgBr_2\rightarrow 2LiBr+Mg[/tex]
Explanation:
Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.
A more reactive element is one which can easily lose or gain electrons as compared to the other element.
The balanced chemical equation is:
[tex]2Li+MgBr_2\rightarrow 2LiBr+Mg[/tex]
Here Lithium being more reactive than magnesium, it can easily displace magnesium from its salt solution and form lithium bromide and magneium in elemental form.

Write the complimentary DNA strand for the given strand of DNA
CGTAAGCGCTAATTA
Answer:
The answer is GCATTCGCGATTAAT
Explanation:
"Chargaff's rule, also known as the complementary base pairing rule, states that DNA base pairs are always adenine with thymine (A-T) and cytosine with guanine (C-G). A purine always pairs with a pyrimidine and vice versa. However, A doesn't pair with C, despite that being a purine and a pyrimidine."
If this is not the answer, try the translation with the 5-3 Strategy and if not still then try using U instead of T.

What is the mass of 8.03 mole of NH3? (NH3 is 17g/mol)
Answer:
the mass of 8.03 mole of NH3 is 136.51 g
Explanation:
The computation of the mass is shown below:
As we know that
Mass = number of moles × molar mass
= 8.03 mol × 17 g/mol
= 136.51 g
Hence, the mass of 8.03 mole of NH3 is 136.51 g
We simply multiplied the number of moles with the molar mass so that the mass could come
The atomic mass of Cu is 63.5. Find its electrochemical equivalent
Answer:
The electrochemical equivalent of copper, Cu, is 3.29015544 × 10⁻⁷ g/C
Explanation:
The given parameters are;
The element for which the electrochemical equivalent is sought = Copper
The atomic mass of copper = 63.5
The electrochemical equivalent, 'Z', of an element or a substance is the mass, 'm', of the element or substance deposited by one coulomb of electricity, which is equivalent to a 1 ampere current flowing for a period of 1 second
Mathematically, we have;
m = Z·I·t = Z·Q
We have;
Cu²⁺ (aq) + 2·e⁻ → Cu
Therefore, one mole of Cu, is deposited by 2 moles of electrons
The charge carried one mole of electrons = 1 Faraday = 96500 C
∴ The charge carried two moles of electrons, Q = 2 × 96500 C = 193,000 C
Given that the mass of an atom of Cu = 63.5 a.m.u., the mass of one mole of Cu, m = 63.5 g
[tex]Z = \dfrac{m}{Q} = \dfrac{63.5 \ g}{193,000 \ C} = 3.29015544 \times 10^{-4} \, g \cdot C^{-1}[/tex]
∴ Z = 3.29015544 × 10⁻⁴ g/C = 3.29015544 × 10⁻⁷ g/C
The electrochemical equivalent of copper, Cu, is Z = 3.29015544 × 10⁻⁷ g/C

How would the reactivity of an element with one valence electron vary from an element with 8 valence electrons
Answer:
An element with 1only one valence electron is extremely reactive while an element with 8 valence electrons is very stable and does not react most of the times
Explanation:
Valency is the number of electrons in the outermost shell of the atom. It shows the ease with which elements react and combine with each other.
An element can take a maximum of 8 electrons in most of its outermost shells. As a matter of fact, the goal for its stability is to attain a structure with all 8 slots for electrons in its outer shell filled up. The element can either do this by adding or removing electrons.
The ease with which it adds or removes the electrons shows its reactivity. If it has only one electron to lose, (the valence electron) the element will be very reactive because this is relatively easier to do when compared with 2 electrons, three electrons, and so on. An element with 8 electrons in its outer shell is very stable and does not need to react anymore. an example of this is Neon and Argon.
