Which statement best compares bacteria and fungi?
O Most bacteria and fungi are harmless and may be beneficial to other
living things.
Bacteria are living organisms, whereas, fungi are not.
Bacteria and fungi always cause infectious diseases.
Both bacteria and fungi rely on living organisms to reproduce and survive.
Answer:
Both bacteria and fungi rely on living organisms to reproduce and survive.
Most bacteria and fungi are harmless and may be beneficial to other
living things. So, the correct option is (A).
What are Bacteria and Fungi?Bacteria and fungi are two types of organisms that belong to different class of organisms while they are prokaryotic and eukaryotic in nature respectively. They are present in various life forms like parasitic (bacteria), saprophytic (fungi) etc. They are harmless in nature and can be beneficial to other living things as well.
They have mutual relationships with other living organisms, which are beneficial to both.
For example, some species of bacteria help fix nitrogen in the root nodules of leguminous plants, while fungi form a mutualistic relationship with algae called lichens where they benefit each other in one way or another.
Thus, most bacteria and fungi are harmless and may be beneficial to other living things. So, the correct option is (A).

The boiling point of water is 1000C.
(a) Once boiling starts, why does the temperature not rise accordingly even heat is supplied? (b) Steam causes more severe burns than boiled water at the same temperature. Why?.
Answer:
a) The heat which we supply to water during boiling is used to overcome these forces of attraction between the particles so that they become totally free and change into a gas. This latent heat does not increase the kinetic energy of water particles and hence no rise in temperature takes place during the boiling of water.
b) Steam produces more severe burns than boiling water even though both are at 100oC because steam contains more heat, in the form of latent heat, than boiling water.

At a pressure of 710 atm, gas has an unknown volume. When the pressure is decreased
to 0.96 atm, the volume is 3700 mL. What was the original volume of the gas?
Answer:
5.00 mLExplanation:
The original volume can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we are finding the original volume
[tex]V_1 = \frac{P_2V_2}{P_1} \\[/tex]
From the question we have
[tex]V_1 = \frac{3700 \times 0.96}{710} = \frac{3552}{710} \\ = 5.002816...[/tex]
We have the final answer as
5.00 mLHope this helps you

Why might a metallic compound be mistaken for an ionic compound, based on its physical properties?
A. Both metallic and ionic compounds form brittle crystal lattice structures. Thus, they are unable to absorb energy and cannot form new shapes.
B. Both metallic and ionic compounds are composed of metal atoms in a bond. However, only ionic compounds show extreme luster.
C. Both metallic and ionic compounds form ductile compounds. Thus, they are able to be reshaped without breaking the bond of the compound.
D. Both metallic and ionic compounds can conduct electricity when molten. However, only metallic compounds can conduct electricity in a solid state.
Answer:
(D). Both metallic and ionic compounds can conduct electricity when molten. However, only metallic compounds can conduct electricity in a solid state.
Explanation:
Metallic compound have the ability to conduct electricity. Since they are Metals they have loosely held electrons which can contribute to electricity conduction.
Ionic compound are brittle physically, ionic compound cannot conduct electricity while being in solid state as the ions are held strongly by electrostatic force of attraction, they can only conduct electricity while they are in molten or aqueous state. In molten state they are forming ions, and ions are free to move within the solution and therefore contribute to electricity conduction.
What is the total number of Joules lost when 10. grams of water at 80.°C is cooled to 60.°C?
Answer:
The total number of Joules lost to the surrounding is -837.2 J
Explanation:
Given that:
mass = 10 grams
initial temperature = 80°C
Final temperature = 60 °C
Specific heat of water= c = 4.186 J/g. °C
The total number of Joules lost can be determined by finding the amount of heat energy Q released by using the formula:
Q = mC ΔT
Q = 10 × 4.186 × (60 - 80)° C
Q = 10 × 4.186 × - 20° C
Q = -837.2 J
Thus, the total number of Joules lost to the surrounding is -837.2 J

Potassium has only one valence electron. ... Whereas, calcium has two valence electrons, so it requires more energy for the removal of a valence electron. Due to this potassium is more reactive than calcium.
Bye Have A Great Day! =)If block 1 were broken in two equal pieces, what would be the density of each piece? Why?
Explanation:
The density of the new blocks will be the density of the original block.
For example if the density of the block is 2g/cm³, when the block is broken down into two, each of the new block will have a density of 2g/cm³.
Density is an intensive property of matter. It does not depend on the mass of the substance available. Every sample of a substance have the same value of density.Help plz:))) I’ll mark u brainliest

If you are following the recipe for a cake, how will the order in which you add the ingredients affect the mass of the batter? (1 point)
A. It will have no effect because the order in which ingredients are mixed will not change the fact that matter cannot be created nor destroyed.
B. If you add the liquid ingredients first, the final result will have less mass than if you added the dry ingredients first. This is because the dry ingredients will dissolve in the liquid ingredients.
C. If you add the dry ingredients first, the final result will have less mass than if you added the liquid ingredients first. This is because the dry ingredients will be dissolved by the liquid ingredients.
D. It will have no effect because heating an object never produces a chemical change and only chemical changes can create or destroy mass.
In cake, the ingredients have been changed to the baked cake, so the order of putting the ingredients has no effect on the mass of matter. Thus, option A is correct.
The baking of cake has been corresponds with the addition of the ingredients, thereby process mixing in order to create the reactant mixture that has been heated at the specific temperature for a specified time period. The resultant has been the baked cake matter.
The reagents and products all are matter, and baking has been the chemical reaction. According to the law of conservation of mass, matter cannot be created nor be destroyed in a chemical reaction; it can be changed from one form to another.
In cake, the ingredients have been changed to the baked cake, so the order of putting the ingredients has no effect on the mass of matter. Thus, option A is correct.

Please help with my chemistry homework! : Fuel burns in a car engine. Describe how oxides of nitrogen are produced in a car engine. I stated: -very high temperatures in the car engine create a reaction of oxygen and nitrogen. But I'm unsure if this is correct and would award me the full 2 marks?
Answer:
Your statement is right.
Explanation:
When fuels are burned in vehicle engines, high temperatures are produced. At this high temperature, nitrogen and oxygen from the air combine with each other to produce nitrogen monoxide (NO). When this nitrogen monoxide is released in the air from vehicle exhaust systems, it combines with oxygen present in the air to form nitrogen dioxide (NO2).
