B.Experiments with different magnification lenses showed that germs were real and could be observed. C.Experiments with animals showed that dominant genes could lead to risks of disease. D.Experiments with shallow dishes showed that groups of germs could be grown so they could be seen without microscopes.
Answer:
A.Experiments with cooking food showed that disease-carrying germs in food could be killed when heated.
Explanation:
Louis Pasteur (1822-1895) is regarded as the father of immunology. He extensively studied microbes and their effect on food. He discovered that microorganisms were responsible for the spoilage of food.
His most important discovery was the fact that heating wine to 55°C will lead to the death of microorganisms and prevented wine from spoiling and did not affect its taste. This process is known as pasteurization.

A beaker contains 1.0 M NaOH(aq) solution. To produce a NaOH(aq) solution of molar concentration 0.20 M, we transfer 2.0 ml (cm^3) out of this beaker into a 25 ml cylinder and add distilled water until the total volume reading becomes
A) 12ml
B)10ml
C)8ml
D)5ml
E)2ml
Answer: B) 10 ml
Explanation:
According to the dilution law,
\(M_1V_1=M_2V_2\)
where,
\(M_1\) = molarity of stock \(NaOH\) solution = 1.0 M
\(V_1\) = volume of stock \(NaOH\) solution = 2.0 ml
\(M_1\) = molarity of dilute \(NaOH\) solution = 0.20 M
\(V_1\) = volume of diluted \(NaOH\) solution = ?
Putting in the values we get:
\(1.0\times 2.0=0.20\times V_2\)
\(V_2=10ml\)
Therefore, final volume reading is 10 ml

Why is it so important to monitor the speed of a variable speed pump?
a.) To prevent excessive temperatures from developing
b.) To prevent vibration from developing
c.) To prevent speed oscillation from occurring
d.) To prevent cavitation from occurring
It is important to monitor the speed of a variable speed pump To prevent excessive temperatures from developing, To prevent vibration from developing, To prevent speed oscillation from occurring, To prevent cavitation from occurring.
The correct options are a, b, c and d.
Monitoring the speed of a variable speed pump is crucial for several reasons. Firstly, excessive temperatures can develop if the speed is not properly controlled. Running the pump at too high a speed can cause friction and heat, leading to mechanical failure and potential safety hazards.
Secondly, monitoring the speed helps to prevent vibration from developing. Uncontrolled vibration can damage the pump and surrounding equipment, as well as creating noise pollution.
Additionally, speed oscillation can occur if the speed is not properly regulated, leading to inconsistent flow rates and reduced efficiency.
Finally, cavitation can occur if the speed is too high, causing bubbles to form in the fluid being pumped. This can damage the pump and decrease its lifespan. Overall, monitoring the speed of a variable speed pump helps to ensure optimal performance, prevent damage to equipment, and maintain a safe working environment.
Therefor, option a, b, c and d are correct.

Which has more water for equal volumes of snow: snow with a density of а 0.5 g/mL or snow with a density of 0.25 g/mL?
\(\\ \tt\hookrightarrow Density=\dfrac{Mass}{Volume}\)
\(\\ \tt\hookrightarrow Volume=\dfrac{Mass}{Density}\)
\(\\ \tt\hookrightarrow Volume\propto \dfrac{1}{Density}\)
If density is less volume is moreSnow with density 0.25g/ml has more volume
The volume of snow with a density of 0.5 g/mL will have more water than the snow with a density of 0.25 g/mL.
What are density and volume?Density is the mass per unit volume. Density can be calculated by knowing the mass and volume of the object. Volume is the space occupied by an object.
Let's take the volume to be 100
The densities are 0.5 g/mL and 0.25 g/mL
so, volume = mass / 0.5 g/ml
mass = 100 x 0.5 = 50
Second density = 0.25 g/mL
volume = mass / 0.25 g/ml
Mass = 100 x 0.25 = 25.
The mass is directly proportional to the density. So, if the mass has increased the density is also increased, so the volume of snow with a density of 0.5 g/mL will have more water than the snow with a density of 0.25 g/mL.
Thus, more water will be present in the amount of snow with a density of 0.5 g/mL than the snow with a density of 0.25 g/mL.

if S contributes a charge of -4, then what is the charge of the gold in AuS2?
The charge of the gold ion in AuS₂ is +4.
How to find a charge on a compound?The charge of the gold in AuS₂ can be determined by balancing the charges of the individual components. In this case, the sulfide (S) ion has a charge of -2, and there are two sulfide ions in AuS₂, so the total charge from the sulfide ions is -4. To balance this charge, the gold ion must have a charge of +4.
Therefore, the charge of the gold ion in AuS₂ is +4. This information can be used to write the balanced chemical equation for the formation of AuS₂, which would be represented as:
Au⁺⁴ + 2S⁻² → AuS₂
This equation shows that two sulfide ions with a charge of -2 are combining with a single gold ion with a charge of +4 to form the compound AuS₂.

How many milliliters of 0.50M H2SO4 would be needed to neutralize 15.0mL of 1.00M KOH?
In order to neutralise 15.0 mL of 1.00 M KOH, we therefore require 15.0 mL of 0.50 M Sulfuric acid.
What is a neutralise example?Strong acid and strong base reactions produce a salt that is neither acidic nor basic in nature, or neutral. For instance, sodium chloride and water are produced when HCl (hydrochloric acid), a powerful acid, combines with NaOH, a powerful base.
First, let's calculate the number of moles of potassium hydroxide in 15.0 mL of 1.00 M solution:
moles of Potassium hydroxide = concentration × volume
moles of Potassium hydroxide = 1.00 M × 15.0 mL / 1000 mL per L = 0.015 mol
moles of Sulfuric acid = moles of KOH / 2 = 0.015 mol / 2 = 0.0075 mol
moles of Sulfuric acid = concentration × volume
0.0075 mol = 0.50 M × volume
volume = 0.0075 mol / 0.50 M = 0.015 L
volume in mL = 0.015 L × 1000 mL per L = 15.0 mL

What is the product of reductior of ethyl 4-oxobutanoate with sodium borohydride in ethanol at room temperature for 30 minutes? A Ethyl 4-hydroxybutanoate B 1,4-Butanediol C 4-Hydroxybutanal D Ethyl butanoate
The product of the reduction of ethyl 4-oxobutanoate with sodium borohydride in ethanol at room temperature for 30 minutes is Ethyl 4-hydroxybutanoate (Option A).
What is ethyl 4-oxobutanoate and what does it look like?
Ethyl 4-oxobutanoate, also known as ethyl acetoacetate, is an organic compound with the chemical formula CH₃C(O)CH₂CO₂C₂H₅. It is derived from acetoacetic acid and is an ester of acetoacetic acid.
Ethyl 4-oxobutanoate is a colorless liquid with a fruity odor.
During the reduction reaction, sodium borohydride (NaBH₄) acts as a reducing agent, donating hydride ions (H-) to the carbonyl group of the ethyl 4-oxobutanoate. This results in the conversion of the carbonyl group (C=O) to a hydroxyl group (OH) and the formation of the corresponding alcohol.
Therefore, the correct product of the reduction of ethyl 4-oxobutanoate with sodium borohydride is Ethyl 4-hydroxybutanoate (Option A).

how many grams of oxygen can be produced from the decomposition of 100 g of kclo3
the number of grams of oxygen that are produced from the decomposition of 100g of kclo3 is 39.14 grams.
The balanced chemical equation for the decomposition of potassium chlorate (KClO3) is:
2KClO3(s) -> 2KCl(s) + 3O2(g)
According to this equation, 2 moles of KClO3 will produce 3 moles of O2.
The molar mass of KClO3 is approximately 122.55 g/mol, so 100 g of KClO3 is equivalent to 100/122.55 = 0.815 moles of KClO3.
Using the mole ratio from the balanced equation, we can calculate the number of moles of O2 produced:
0.815 moles KClO3 x (3 moles O2 / 2 moles KClO3) = 1.223 moles O2
Finally, we can calculate the mass of O2 produced using its molar mass, which is approximately 32 g/mol:
1.223 moles O2 x 32 g/mol = 39.14 g of O2
Therefore, approximately 39.14 grams of oxygen can be produced from the decomposition of 100 g of KClO3.

The approximate amount of heat produced by the reaction is 2884 J
We'll begin by calculating the mass of the solution.
Volume of HCl = 50 mL
Volume of NaOH = 50 mL
Total volume = 50 + 50 = 100 mL
Density of solution = 1 g/mL
Mass of solution =?
Mass = Density × Volume
Mass = 1 × 100
Mass of solution = 100 g
Next, we shall determine the change in the temperature.
Initial temperature (T₁) = 22 °C
Final temperature (T₂) = 28.9 °C
Change in temperature (ΔT) = ?
ΔT = T₂ – T₁
ΔT = 28.9 – 22
ΔT = 6.9 °C
Finally, we shall determine the heat produced by the reaction. This can be obtained as follow:
Mass of solution = 100 g
Change in temperature (ΔT) = 6.9 °C
Specific heat capacity (C) = 4.18 J/g°C
Heat (Q) = ?
Q = MCΔT
Q = 100 × 4.18 × 6.9
