This group of fungi has reproductive cells with flagella so that they can swim
Answer:
The answer would be chytrids.
Chytridiomycota (chytrids) is a group of fungi that has reproductive cells with flagella so that they can swim.
What is Chytridiomycota?The fungus known as the amphibian chytrid fungus only infects frogs. A frog uses its skin to maintain homeostasis. The chytrid fungus ruins the frog's ability to swallow, exchange ions, and function normally when it affects its skin.
The fungus targets the keratin-containing areas of a frog's skin. Frogs have trouble breathing because they use their skin for respiration.
As a class of fungi, chytrids are regarded as the most basic. They are primarily aquatic, and the only fungus cells known to contain flagella are those of the gametes. They can reproduce asexually or sexually; the latter method produces zoospores.
Therefore, a class of fungi known as chytrids possesses reproductive cells with flagella that allow them to swim.

What mass of sulfur trioxide is formed from 96g of sulfur dioxide?
2 SO2+O2 –> 2 SO3
Answer:
120 g SO3
Explanation:
128 g SO2 -> 160 g SO3
96 g SO2 -> x
x= (96 g SO2 * 160 g SO3)/128 g SO2
x= 120 g SO3
The mass of sulfur trioxide, SO₃, formed is 120 g
The balanced equation for the reaction is given below:
2SO₂ + O₂ —> 2SO₃Next, we shall determine the mass of SO₂ that reacted and the mass of SO₃ produced from the balanced equation. This can be obtained as follow:
Molar mass of SO₂ = 32 + (16×2)
= 32 + 32
= 64 g /mol
Mass of SO₂ from the balanced equation = 2 × 64 = 128 g
Molar mass of SO₃ = 32 + (16×3)
= 32 + 48
= 80 g /mol
Mass of SO₃ from the balanced equation = 2 × 80 = 160 g
Thus,
From the balanced equation above,
128 g of SO₂ reacted to produce 160 g of SO₃.
Finally, we shall determine the mass of SO₃ by the reaction of 96 g of SO₂. This can be obtained as follow:
From the balanced equation above,
128 g of SO₂ reacted to produce 160 g of SO₃.
Therefore, 96 g of SO₂ will react to produce = [tex]\frac{96 X 160}{128}\\\\[/tex] = 120 g of SO₃.
Therefore, the mass of SO₃ formed is 120 g

Answer:
[tex]\rm _{27}^{60}\text{Co} \longrightarrow \, _{-1}^{0}\text{e} + \, _{28}^{60}\text{Ni}[/tex]
Explanation:
The unbalanced nuclear equation is
[tex]\rm _{27}^{60}\text{Co} \longrightarrow \, _{-1}^{0}\text{e} + \, ?[/tex]
Let's write the question mark as a nuclear symbol.
[tex]\rm _{27}^{60}\text{Co} \longrightarrow \, _{-1}^{0}\text{e} + \, _{Z}^{A}\text{X}[/tex]
The main point to remember in balancing nuclear equations is that the sums of the superscripts and the subscripts must be the same on each side of the equation.
Then
60 = 0 + A, so A = 60 - 0 = 60, and
27 = -1 + Z, so Z = 27 + 1 = 28
Your nuclear equation becomes
[tex]\rm _{27}^{60}\text{Co} \longrightarrow \, _{-1}^{0}\text{e} + \, _{28}^{60}\text{X}[/tex]
Element 28 is nickel, so the balanced nuclear equation is
[tex]\rm _{27}^{60}\text{Co} \longrightarrow \, _{-1}^{0}\text{e} + \, _{28}^{60}\text{Ni}[/tex]

Referencing the reasoning you used from #1, explain the difference between objects that feel hot and those that
feel "cold".
Answer:
The temperature of the cold water is lower than the warm one. So, when we put the hand in the warm from the cold water, our hand will absorb heat, causing the hand to feel hot. Thus, we can conclude that the more heat it absorbs, the more hotter it is. Whereas the more heat it releases, the colder it is.

An insoluble solid has a mass of 80.0 g . It is placed in a graduated cylinder containing 40.0 mL which then rises to 80.0 mL. What is the density of the solid?
a
(A) 0.300 g/mL
b
(B) 0.50 g/mL
c
(C) 2.00 g/mL
d
(D) 3.33 g/mL
Answer:
The correct answer is (B) 0.50 g/mL
Explanation:
The density of a subtance is equal to the ratio between its mass and its volume, as follows:
d = m/v
In the problem, the mass is equal to 80.0 g. The volume is given by the increment in volume in the graduated cylinder when the solid is placed because the solid is insoluble so it displaces the liquid and increases the volume. The initial volume was 40.0 ml and the final volume was 80.0 ml, so:
V = Final volume - initial volume = 80.0 ml - 40.0 ml = 40.0 ml
Finally, we calculate the density by dividing the mass into the volume:
[tex]d= \frac{m}{v} = \frac{80.0 g }{40.0 ml} = 0.50 g/ml[/tex]

butane (C4H10):
carbon monoxide (CO):
Answer:
ozone (O3): inorganic
methane (CH4): organic
aluminum hydroxide (Al(OH)3): inorganic
butane (C4H10): organic
carbon monoxide (CO): inorganic
Explanation:
An inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. Some simple compounds that contain carbon are often considered inorganic. Examples of inorganic compounds include carbon monoxide , carbon dioxide , carbonates, carbides , cyanides, cyanates, and thiocyanates. Most of these compounds are normal parts of mostly organic systems, including living organisms. When a chemical substance is classified as inorganic, it does not necessarily mean that it does not occur within
living things.
Organic compounds typically contain the carbon-hydrogen bonds. The carbon atoms often catenate and most organic substances occur in living systems and are products of biochemical reactions in living organisms. However, organic substances can also be synthetic and can be prepared in the laboratory.

A sample of a compound contains 60.0 g C and 5.05 g H. It’s molar mass is 78.12 g/mol. What is the compound’s molecular formula?
Answer:
C6H6
Explanation:
C : 60.0 g*1 mol/12 .01g = 5.00 mol
H: 5.05 g * 1 mol/1.01 g= 5.10 mol
C:H = 5.00 mol : 5.10 mol = 1:1
CH is an empirical formula
Molar mass (12.01 +1.01)=13.02 g/mol
78.12g/mol /13.02 g/mol =6
