what is the main difference between sexual and asexual reproduction
Answer:
Asexual reproduction does not involve sex cells or fertilisation . Only one parent is required, unlike sexual reproduction which needs two parents. Since there is only one parent, there is no fusion of gametes and no mixing of genetic information.
The main difference between sexual and asexual reproduction is that sexual reproduction involves the fusion of gametes, while asexual reproduction does not.
In sexual reproduction, offspring are produced through the fusion of gametes (reproductive cells) from two parent organisms. This fusion, known as fertilization, results in offspring that inherit genetic material from both parents. This genetic recombination introduces variation in the offspring, promoting genetic diversity within a population.
In contrast, asexual reproduction involves the production of offspring without the involvement of gametes or the fusion of genetic material from two parents. A single parent organism reproduces by generating genetically identical or near-identical offspring through various methods such as budding, fragmentation, or binary fission. Asexual reproduction typically leads to offspring that are genetically identical to the parent, lacking the genetic diversity observed in sexual reproduction.

Explanation:
what properties are you talking about?
which elements from the periodic table are the least reactive
Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds.
Group 18; The Noble Gases contains the elements on the periodic table that would be the least reactive out of all the elements. So, this include any gas element, such as helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og). Hence, if you have the options:

Excess Na2SO4 (aq) is added to a 42.53 mL sample of Ba(NO3)2(aq).
1. What is the formula of the precipitate?
The formula for the precipitate is 2Na(NO3)(aq).
2. If 3.046 grams of precipitate was formed, what was the molarity of the Ba(NO3)2(aq)?
1. The formula of the precipitate formed is Ba₂SO₄(s)
2. The molarity of the Ba(NO₃)₂ solution is 0.188 M
1. Determination of the formula of the precipitate formed.
We'll begin by writing the net ionic equation for the reaction between Na₂SO₄ and Ba(NO₃)₂. This is given below:Na₂SO₄(aq) + Ba(NO₃)₂(aq) —>
2Na⁺(aq) + SO₄²¯(aq) + Ba²⁺(aq) + 2NO₃¯(aq) —> Ba₂SO₄(s) + 2Na⁺(aq) + 2NO₃¯(aq)
Cancel the spectator ions (i.e Na⁺ and NO₃¯) to obtain the net ionic equation
SO₄²¯(aq) + Ba²⁺(aq) —> Ba₂SO₄(s)
Therefore, the formula of the precipitate formed is Ba₂SO₄(s)
2. Determination of the molarity of Ba(NO₃)₂
We'll begin by calculating the number of mole of in 3.046 g of precipitate, Ba₂SO₄Molar mass of Ba₂SO₄ = (2×137) + 32 + (4×16) = 370 g/mol
Mass of Ba₂SO₄ = 3.046 g
Mole of Ba₂SO₄ =?Mole = mass /molar mass
Mole of Ba₂SO₄ = 3.046 / 370
Mole of Ba₂SO₄ = 0.008 mole Next, we shall determine the number of mole of Ba(NO₃)₂ required to produce 0.008 mole of Ba₂SO₄Na₂SO₄(aq) + Ba(NO₃)₂(aq) —> Ba₂SO₄(s) + 2NaNO₃(aq)
From the balanced equation above,
1 mole of Ba(NO₃)₂ reacted to produce 1 mole Ba₂SO₄.
Therefore,
0.008 mole of Ba(NO₃)₂ will also react to produce 0.008 mole of Ba₂SO₄
Thus, 0.008 mole of Ba(NO₃)₂ is required for the reaction.
Finally, we shall determine the molarity of the Ba(NO₃)₂ solutionMole of Ba(NO₃)₂ = 0.008 mole
Volume = 42.53 mL = 42.53 / 1000 = 0.04253 L
Molarity of Ba(NO₃)₂ =?Molarity = mole / Volume
Molarity of Ba(NO₃)₂ = 0.008 / 0.04253
Molarity of Ba(NO₃)₂ = 0.188 MLearn more: https://brainly.com/question/13403073

2. Calculate the heat of combustion of C6H14(l) in kJ/mol if 1.66 g of C6H14(l) were ignited in a calorimeter containing 2750. g H2O. A 3.54˚C temperature rise was observed. The calorimeter constant is 11.2 kJ/˚C. The specific heat of water is 4.184 J/g˚C.
This problem is describing the combustion experiment where by the heat of combustion of 1.66 g of liquid C6H14 can be calculated via calorimetry. The calorimeter (C=11.2kJ/°C) contains 2750. grams of water with a temperature rise of 3.54 °C, it means we can calculate the total heat released by the combustion of this hydrocarbon via:
[tex]Q_{combustion}=-(Q_{calorimeter}+Q_{water})[/tex]
Because the heat of combustion is released to the water and the calorimeter. Next, we break down each heat and subsequently plug in the given values:
[tex]Q_{combustion}=-(11200\frac{J}{\°C}*3.54\°C +2750.g*4.184\frac{J}{g\°C}*3.54\°C )\\\\Q_{combustion}=-80,379J=-80.4kJ[/tex]
After that, we calculate the moles of C6H14 by considering the given mass and its molar mass (86.18 g/mol):
[tex]n=1.66g*\frac{1mol}{86.18g} =0.01926mol[/tex]
And finally, we divide the total heat of combistion by the moles to get the heat of combustion:
[tex]\Delta H_{comb}=\frac{-80.4kJ}{0.01926mol} =4,174\frac{kJ}{mol}[/tex]

Which is the correct word equation for photosynthesis? *
Answer:
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
Consider the following chemical reaction.
3 Zn(C₂H₃O₂)₂(aq) + 2 Na₃PO₄(aq) → 6 NaC₂H₃O₂(aq) + Zn₃(PO₄)₂(s)
A chemist makes a solution of zinc acetate by dissolving 20.5 g Zn(C₂H₃O₂)₂ in 105 mL H₂O. What is the concentration of this zinc acetate solution?
The concentration of the zinc acetate, Zn(C₂H₃O₂) solution is 1.067 M
We'll begin by calculating the number of mole in 20.5 g of Zn(C₂H₃O₂)₂Mass of Zn(C₂H₃O₂)₂ = 20.5 g
Molar mass of Zn(C₂H₃O₂)₂ = 65 + 2[(12×2) + (3×1) + (16×2)]
= 65 + 2[59]
= 183 g/mol
Mole of Zn(C₂H₃O₂)₂ =?Mole = mass / molar mass
Mole of Zn(C₂H₃O₂)₂ = 20.5 / 183
Mole of Zn(C₂H₃O₂)₂ = 0.112 mole Finally, we shall determine concentration of Zn(C₂H₃O₂). This can be obtained as follow:Mole of Zn(C₂H₃O₂)₂ = 0.112 mole
Volume = 105 mL = 105 / 1000 = 0.105 L
Concentration of Zn(C₂H₃O₂)₂ =?Concentration = mole / Volume
Concentration of Zn(C₂H₃O₂)₂ = 0.112 / 0.105
Concentration of Zn(C₂H₃O₂)₂ = 1.067 MTherefore, the concentration of the zinc acetate, Zn(C₂H₃O₂) solution is 1.067 M
