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.

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.

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

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.

When 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.

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.Given the following equation...
Fe + H2SO4 → Fe2(SO4)3 + H2
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
2Fe = +6
Fe = +3
The charge of the Fe of Fe₂(SO₄)₃ is +3Answer:
