Answer:
AAU UCG
Explanation:
According to the base-pairing rule, the purine bases always pair with the pyrimidine bases. More specifically, Adenine always pairs with Thymine/Uracil while Guanine always pairs with Cytosine.
T - A

Hence, the transcription of the sequence TTA AGC will produce AAU UCG.
Se sabe que un compuesto contiene 33.002% de carbono,9.063% de hidrogeno y el resto de oxigeno. El espectrometro de masas indica que la masa molecular aproximada es de 191g/mol(cual es la formula empirica y molecular probable
Answer:
CH3O
C6H18O6
Explanation:
Porcentaje de masa de oxígeno = 100% - (33,002% + 9,063%) = 57,935%
Divida el porcentaje en masa de cada elemento por su masa atómica relativa;
H- 9.063 / 1, C- 33.002 / 12, O - 57.935 / 16
H- 9.063, C- 2.75, O- 3.62
Dividir por la proporción más baja;
H-9.063 / 2.75, C- 2.75 / 2.75, O- 3.62 / 2.75
H- 3, C-1, O- 1
Fórmula emperical = CH3O
Dado que la masa molecular es 191 g / mol
Sea n el número de cada átomo de la molécula
Por tanto, su fórmula molecular es; (CH3O) n = 191
[12 + 3 (1) + 16] n = 191
31n = 191
n = 191/31
n = 6
Por lo tanto, la fórmula molecular del compuesto es; (CH3O) 6 que es C6H18O6
please write the process (how soap is made?.......................
Answer:
When oil and lye are combined and heated, the result is soap. This chemical reaction is called saponification. Without lye, saponification isn’t possible, so lye is necessary to create soap.
Suppose you are working in a chemistry lab and trying to make a solution of a substance called Sodium Chloride (which is a solid) of a definite amount and volume. Mention which lab apparatuses you would need to complete your work perfectly.
Answer:
a weighing balance, a measuring cylinder, a spatula, a beaker/flask, and a stirrer
Explanation:
The lab apparatus that would be needed to prepare a solution of sodium chloride would be a weighing balance, a measuring cylinder, a spatula, a beaker/flask, and a stirrer.
The weighing balance would be used to weigh out the required amount of sodium chloride. The beaker or flask would be placed on the weighing balance and its weight zeroed. The spatula would then be sued to take out the sodium chloride from its container into the beaker till the required amount is reached. The measuring cylinder would then be used to measure out the required volume of water which would be added to the salt in the beaker. The stirrer would then be used to stir the mixture in order for the salt to dissolve.
Identify the products in the following chemical resction 2NaHCO3 + CaCI2 --> CaCO3 + CO2 + 2NaCI + H2O
the products are:
CaCO3 Calcium Carbonate
CO2 carbon dioxide
NaCI Sodium chloride
H2O Water

6. Which of the following molecules has a central atom with precisely two unshared
pairs of electrons?
methane, CH4
ammonia, NH3
hydrocyanic acid, HCN
water, H20
CLEAR ALL
Answer:
water, H20
Explanation:
From the given choices, only water has two unshared or lone pairs of electrons in its central atom.
The formula of water is:
H₂O
H is hydrogen with 1 electron
O is oxygen with 8 electrons and 6 valence electrons
To form the covalent bond, the 6 valence electrons are involved. Two out of the 6 bonds with the two oxygen.
The remaining 4 gives the two lone pairs.
What is the meaning of plate tectonics
Answer:
A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest.
A radioactive nucleus can change from one element to another. How does this happen?
A radioactive decay is occurring by the emission of charged particles such alpha or beta to form a new stable atom with changes mass number and atomic number.
What is radioactive decay?Heavy unstable radioactive elements undergo nuclear decay by which they form a stable isotope or new atom with changed atomic number. There are two types of nuclear decays mainly. They are alpha decay and beta decay.
During alpha decay isotopes with higher mass number undergo alpha emission and forming a new species with mass number reduced by 4 units and atomic number reduced by 2 units.
In the case of beta- decay, electrons are emitted from the atom and then forming a new atom with atomic number increased by one unit. For an electron capture process, an electron is captured to the atom forming an element with atomic number reduced by one.

What makes Carbon-14 so useful in “carbon dating” or “radiodating”?
Answer:
Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon. ... The carbon-14 method was developed by the American physicist Willard F. Libby about 1946.

How much energy must be added to a 2-kg piece of wood with a specific heat
of 1760 J/(kg°C) to increase its temperature from 10°C to 50°C?
A. 140,800 J
B. 1,760,000 J
C. 211,200 J
D. 35,200 J
Answer:
A. 140,800 J
Explanation:
Specific heat of a material is defined as the amount of energy required to increase in 1°C 1kg of the material. For wood there are required 1760J perkg per °C.
The equation is:
Q = C*m*ΔT
Where Q is heat in Joules,
C is specific heat (1760J/kg°C),
m is mass (2kg)
ΔT is change in temperature (50°C - 10°C = 40°C)
Replacing:
Q = 1760J/kg°C*2kg*40°C
Q = 140800J
Right option is:
A. 140,800 J

productivity of
photosynthesis affect the
productivity of cellular
respiration?
Answer: it’s the chemicals between the biological
Explanation:
The productivity of photosynthesis affect the productivity of cellular respiration by providing energy.
What is photosynthesis?Photosynthesis is a process where plants prepare their food in the presence of sunlight.
Photosynthesis process chemically illustrated as :
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
From the above it is clear that carbohydrate is produced in the photosynthesis process and this carbohydrate provide energy to the plant for the completion of another chemical process. So, for the cellular respiration plants use this energy.
Hence, the productivity of photosynthesis directly affect the productivity of cellular respiration.

The outer shells of atoms in the common items you encounter are made up of matter particles called electrons.
A negatively charged subatomic particle known as an electron can either be free or attached to an atom (not bound). One of the three main types of particles within an atom is an electron that is bonded to it.
The other two are protons and neutrons. The nucleus of an atom is made up of electrons, protons, and neutrons together.

What is the charge (oxidation number) of Fe in Fe2(SO4)3 in 334 g of Fe2(SO4)3 ? (use atomic masses rounded to the nearest whole number.)
Answer:
The charge is +3
Explanation:
In Fe₂(SO₄)₃ the global charge is 0.
As we know, the sulfate ion, SO₄, has a charge of -2, as there are 3 SO₄ ions in the molecule, the global charge is -2*3 = -6. To solve for the charge of Fe we can use:
2Fe - 6 = 0
