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

What has the lowest ionization erergy?
Fluorine (F)
O Francium (Fr)
O Helium (He)
O lodine (1)
Answer:
Francium (Fr)
Explanation:
From the given choices, francium will have the lowest ionization energy.
Ionization energy is the energy required to remove the most loosely held electron within an atom.
The magnitude of the ionization energy depends on the characteristics of the atom in relation to its nuclear charge, atomic radius, stability etc.
Generally on the periodic table, ionization energy increases from left to right on the tableAs you go from metals to non-metals and to gases, the value of the ionization energy increases steadily. Down the group, the value reduces. Since Francium is the most metallic of all the given choices, it has the highest ionization energy.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.

what should we use in soap making process:-
a) potassium hydroxide
b) sodium hydroxide (lye)
Explain why it should be used
Sodium hydroxide, with the formula NaOH, is usually used in products as a pH adjuster. It's also used in soap-making to turn fats and oils into soap. You can find sodium hydroxide (also called caustic soda or lye) in its pure form in the cleaning aisle, since it's also really handy for clearing up clogged drains.
4. How does the
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.

Compute the number of ions in 58.5 g oh nacl
Answer: Explanation:
58.5 g of Na Cl = 1 mole 5.85 g ofNaCl = 1 X 5.85/58.5 = 0.1 mole Each molecule of NaCI contains one Na ion and one Cl ion = 2 ions Total moles of ions in 0.1 mole of NaCI = 2 x 0.1 = 0.2 molesWhen building electric circuits,_______ flow along the path ( wires, energy source, and resistor(s)).
-neutrons
-matter
-electrons
-protons
Electron is negatively charged particle. When building electric circuits electron flow along the path. so, option C is correct.
What is Electron ?Electrons are fundamental to many physical processes, including gravity, electromagnetic interactions, weak interactions, electricity, magnetism, chemistry, and thermal conductivity.
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.
Thus, Option C is correct.

Which of the following metals is paramagnetic?
Question 5 options:
A)
Calcium
B)
Magnesium
C)
Sodium
D)
Beryllium
Answer:
A , B, C
Explanation: D is a Diamagnetic
The metals that are paramagnetic are Calcium, Magnesium, and Sodium. The correct options are A, B, and C.
What is paramagnetism?A weak magnetic field supplied externally can weakly attract some materials, which then create internal magnetic fields that are directed in the same direction as the applied magnetic field. This phenomenon is known as paramagnetism.
Despite not having an unpaired electron, the metal magnesium exhibits paramagnetic behavior. Sodium is also paramagnetic.
Atoms that have their electrons coupled are said to be diamagnetic, whereas those that don't are said to be paramagnetic. However, despite having no free electrons, calcium is said to be paramagnetic.
Thus, the correct options are A, Calcium, B, Magnesium, and C. Sodium.

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
