Answer:
Some abiotic factors of the taiga are temperature, precipitation, soil, and sunlight.
Explanation:
emperature affects the taiga because the winter temperature range is -65*F to 30*F (-54*C to -1*C), while the temperature range in the summer is 20*F to 70*F (-7*C to 21*C)
Precipitation affects the taiga because there's some precipitation that falls [30-85 cm. (12-33 in.)].
Soil affects the taiga because there's some acidic and low-in-nutrients soil, and some fertile soil.
Sunlight affects the taiga because there are small amounts of it that reach the ground.
The taiga biome's abiotic components include temperature, sunshine, soil, air, water, etc. Cold arctic air predominates in the taiga environment. The taiga receives more light in the summer, which causes the days to be hotter.
What are abiotic components ?Abiotic elements, also known as abiotic factors, are non-living chemical and physical elements of the environment that have an impact on the health of living things and the operation of ecosystems. Biology as a whole is supported by abiotic causes and the phenomena that go along with them.
Biotic and abiotic components, such as rainfall, in that order. The taiga is the biggest biome on Earth's surface and features a diversity of migratory and resident creatures. It also has long, cold, and dry winters and short, warm, and moist summers.
The Taiga biome is restricted by four primary criteria. Fire, temperature, the quantity of nutrients in the soil, and sunshine are the four limiting elements. Because certain plants, like the Jack Pine, recover after fire, it is a limiting element in the Taiga biome.
Thus, The taiga biome's abiotic components include temperature, sunshine, soil, air, water, etc.

Why might it be important to test one variable at a time when doing an experiment?
Answer:
If you change everything at once, you may not know what caused the end result.
Explanation:
If you have Variable A (Salt), Variable B (Potassium), and the Control of Water, you might mix everything together, so you mix salt, potassium and water together. It is known that Potassium reacts very aggressively in water, but since you mixed everything together, you might think that salt+potassium+water goes boom, while it is actually potassium+water=boom.

Answer:
I think it's replacement because the B and D just swap places in the end equation
Answer:
that would be replacment
Explanation:
if you look at the formula the B and D are replaced with each other
synthesis is when it looks like A+B--> AB
decompositions looks like AB--> A+B

Answer:
a )0.05 moles of O₂
b) 1.1207 dm³
c) 0.3× 10²³ atoms of oxygen
d) 1.6 g
Explanation:
Given data:
Number of molecules of O₂ = 3.01 × 10²² molecules
Number of moles of O₂ = ?
Volume of oxygen at ATP = ?
Number of oxygen atoms = ?
Mass of oxygen = ?
Solution:
The given problem will solve by using Avogadro number.
"It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance". The number 6.022 × 10²³ is called Avogadro number.
Moles of oxygen:
1 mole = 6.022 × 10²³ molecules
3.01 × 10²² molecules × 1 mol / 6.022 × 10²³ molecules
0.05 moles of O₂
Number of atoms of oxygen:
1 mole = 6.022 × 10²³ atoms
0.05 mol × 6.022 × 10²³ atoms /1 mol
0.3× 10²³ atoms of oxygen
Volume of oxygen:
1 mole of oxygen at STP occupy 22.414 dm³
0.05 mol × 22.414 dm³ / 1mol
1.1207 dm³
Mass of oxygen:
Mass = number of moles × molar mass
Mass = 0.05 mol × 32 g/mol
Mass = 1.6 g

Answer:
Its can affect the safety of products by, for example, if you put raw chicken in the oven and don't cook it for long enough, it can make you sick
Explanation:
The difference between the calculated and precise worth is referred to as an error or defect. For example, if the two machinists use the same device to detect measurement mistakes, it is not necessary that they obtain the same results. However, there will be a little difference between the two measurements, which is referred to as an error.

The sun's energy influences climate in different ways. For example, the latitudes at the equator receive more intense energy from the sun and therefore have warmer temperatures. How does the sun's energy MOST DIRECTLY influence precipitation in an area?
Answer:
The Sun's energy is transferred as both light and heat energy, that raises the temperature of an area receiving the Sunlight. The increased temperature results in the evaporation of water from surfaces and water bodies, such that the mass of water vapor rises up into the atmosphere and condenses when it gets away from the ground heat to the cooler and higher altitudes
When there is a situation of low pressure, the wind blows into the low pressure, where, in the equator, comprises of high temperature air which could contain considerable amount of vapor from the neighboring water bodies, resulting in the eventual rise of very moist air, up into the atmosphere, that condenses at low temperature at the high altitudes, accumulate into larger masses of liquid water, and fall as rain

Considering the reaction stoichiometry, from the balanced equation and reation stoichiometry, the number of moles of calcium oxide produced is 1 mole.
Chemical reactions are characterized by the appearance of new substances from others. That is, they are processes in which the nature of the substances changes, that is, from some initial substances called reagents, totally different ones called products are obtained.
In this case, you know that the balanced reaction is:
CaCO₃ → CaO + CO₂
Stoichiometry establishes relationships between the molecules or elements that make up the reactants of a chemical equation with the products of said reaction. In other words, stoichiometry determines the ratios between reactants and products in a chemical reaction.
The stoichiometry of a chemical reaction is perfectly established by the chemical equation. In it, the formulas of reactants and products appear preceded by numbers (the stoichiometric coefficients) that indicate the proportions according to which the transformation occurs.
The stoichiometric coefficients of a chemical equation are due to the fact that the atoms present before the reaction must be the same after the reaction, even though the atoms will have been rearranged to produce new substances.
In this case, by reaction stoichiometry, the following amounts of moles of each compound participate in the reaction:
CaCO₃: 1 moleCaO: 1 moleCO₂: 1 moleIn summary, from the balanced equation and reation stoichiometry, the number of moles of calcium oxide produced is 1 mole.

Answer:
a = 6 m/s².
Explanation:
If we have the object with mass of 75 kg and force on it is 50 N then according to given statement its acceleration is 3m/s².
When we double the force on same object by keeping the mass constant then the acceleration will also double. It means force will be 100 N and acceleration will be 6 m/s².
But if we we increase the mass then acceleration goes to decrease.
So,
mass = 75 kg
F = 50 N
a = 3m/s² then by double the amount of force,
mass = 75 g
F = 100 n
a = 6 m/s².
This is actually explain the newton second law. This law stated that the acceleration of object is depend upon its mass and force acting on it.
F= m. a
a = F/m
Thus acceleration is directly proportional to the force and inversely proportional to the mass.

A. The mass of an electron is much greater than the mass of a
proton or a neutron.
B. The mass of an electron is greater than the mass of a proton but
less than the mass of a neutron.
C. The mass of an electron is much less than the mass of a proton or
a neutron.
D. The mass of an electron is greater than the mass of a neutron but
less than the mass of a proton.
Answer:
C. The mass of an electron is much less than the mass of a proton or
a neutron.
Explanation:
When we compare the mass of an electron to that of proton or neutron, the mass of an electron is much less than the mass of a proton or a neutron.
Electrons are negatively charged particles in an atom
Protons are positively charged particles
Neutrons do not carry any charges.
The relative mass of an electron compared to that of a proton is [tex]\frac{1}{1840}[/tex] This is a very small valueElectrons generally have mass of 9.11 x 10⁻³¹kgProtons weigh 1.67 x 10⁻²⁷kgNeutrons weigh 1.68 x 10⁻²⁷kgWe can see that electrons have very small mass and this is why when calculating the mass of an atom, we use the sum of the number of protons and neutrons.
1. A student in lab measures 4.6 grams of copper for an experiment. Upon further analysis he determines that he should have measured out 4.7 grams of copper. What is his percent error?
Answer:
[tex]2.13\%[/tex]
Explanation:
Quantity of copper measured by a student = 4.6 grams
Original quantity of copper = 4.7 grams
Error in measurement = Original quantity of copper - Quantity of copper measured by a student [tex]=4.7-4.6=0.1[/tex] grams
To find the percent error, apply the following formula:
Percent error = (Error in measurement / Original quantity of copper) × 100
