A. It is counterproductive
B. Vinegar
C. Ammonia

Please give me Brainliest
Answer 2

A) Vinegar is an Acid solution while, Ammonia is a basic solution, so when they react they form a neutral solution,

Therefore this is a neutralization reaction

B) The lower the pH value of a solution, the more acidic it is, and vise versa for basic,

In the table Vinegar has the lowest pH value, of 3. Therefore Vinegar is the most acidic in the table

C) The higher the pH value of a solution, the more basic it is

In the table Ammonia has the highest pH value of 12. Therefore Ammonia is the most basic in the table

When calcium chloride is added to a sample of water, the boiling point will _________. A. increase B. decrease C. not change D. first decrease, then increase

Answers

Answer:

C

Explanation:

If you add salt to water, its boiling point increases.

When calcium chloride is added to a sample of water, the boiling point will increase. Option A is correct.

What is boiling point?

The boiling point of the liquid is the temperature at which the vapor pressure of a given liquid equals the external pressure or atmospheric pressure surrounding the given liquid.

The calcium chloride is added to a sample of water it releases the some amount heat and become exothermic and the boiling point will increase due to the reaction of water and calcium chloride.

Therefore, when calcium chloride is added to a sample of water, the boiling point will increase. Option A is correct.

2.00g of Copper wire was added to 50.0 mL of a 0.050M solution of Silver Nitrate. The reaction
produced solid silver and aqueous copper II Nitrate. The silver precipitate was collected and
dried. It was determined that the mass of the silver precipitate was 0.24 g. Use this information
to determine the theoretical yield, limiting reactant, and percent yield.

Answers

Answer:

See explanation

Explanation:

Now, the equation of the reaction is;

Cu(s) + 2AgNO3(aq) --------> Cu(NO3)3 (aq) + 2Ag(s)

Number of moles of silver precipitate = 0.24/108 g/mol= 0.0022 moles

Number of moles of AgNO3 = 50/1000 * 0.050 = 0.0025 Moles

If 2 moles of AgNO3 yields 2 moles of Ag

Then  0.0025 moles of AgNO3 yields  0.0025 * 2/2 = 0.0025 moles of Ag

Number of moles of Cu = 2.00g/63.5 g/mol = 0.03 moles

If 1 mole of Cu yields 2 moles of Ag

0.03 moles of Cu yields  0.03 moles * 2/1 = 0.06 moles of Ag

Hence AgNO3 is the limiting reactant

Theoretical yield of Ag = 0.0025 moles of Ag * 108 = 0.27 g

Actual yield of Ag = 0.24 g

Percent yield = actual yield/theoretical yield * 100

Percent yield = 0.24/0.27 * 100

Percent yield = 88.8%

Answer:

1) The mole ratio of KClO₃ to 3O₂ is 2:3

The reciprocal of the mole ratio of KClO₃ to 3O₂ is 3:2

2) The mole ratio of K to NaNO₃ is 1:1

The reciprocal of the mole ratio of K to NaNO₃ is 1:1

Explanation:

The mole ratio (also known as mole-mole ratio) of two compounds involved in a chemical reaction, is the ratio of the number of moles of the compounds in the reaction which can be obtained from the coefficients of the compounds in the balanced chemical reaction

The mole ratio of compound A to compound B = A:B = A/B

1)The given chemical reaction can be expressed as follows;

2KClO₃ → 2KCl + 3O₂

Therefore;

[tex]The \ mole \ ratio \ of \ KClO_3 \ to \ O_2 = \dfrac{2 \ moles \ of \ KClO_3}{3 \ moles \ of \ O_2} = \dfrac{2}{3} = 2:3[/tex]

[tex]The \ reciprocal \ of \ the \ mole \ ratio \ of \ KClO_3 \ to \ O_2 = \dfrac{3 \ moles \ of \ O_2}{2 \ moles \ of \ KClO_3} = \dfrac{3}{2} = 3:2[/tex]

2) In the reaction NaNO₃ + K → Na + KNO₃

The mole ratio of K to NaNO₃ = 1:1

Therefore;

The reciprocal of the mole ratio of K to NaNO₃ = 1:1

give an example of how an organism can use surface tension?

Answers

Answer:Insects, such as water striders, and spiders, such as fisher spiders, can glide or scamper across the surface of water. These critters are small enough that their weight can be supported almost entirely by surface tension, the relatively weak forces that hold water molecules together.

Explanation:

Answer:

Examples of surface tension Water striders are able to walk on top of water due to a combination of several factors. Water striders use the high surface tension of water and long, hydrophobic legs to help them stay above water. Water striders use this surface tension to their advantage through their highly adapted legs and distributed weight.

Do you
think that the Nitrogen cycle has a negative or positive
impact on the environment?

Answers

Answer:

Nitrogen, the most abundant element in our atmosphere, is crucial to life. Nitrogen is found in soils and plants, in the water we drink, and in the air, we breathe. It is also essential to life: a key building block of DNA, which determines our genetics, is essential to plant growth, and therefore necessary for the food we grow. But as with everything, balance is key: too little nitrogen and plants cannot thrive, leading to low crop yields; but too much nitrogen can be toxic to plants, and can also harm our environment. Plants that do not have enough nitrogen become yellowish and do not grow well and can have smaller flowers and fruits. Farmers can add nitrogen fertilizer to produce better crops, but too much can hurt plants and animals, and pollute our aquatic systems. Understanding the Nitrogen Cycle—how nitrogen moves from the atmosphere to earth, through soils, and back to the atmosphere in an endless Cycle—can help us grow healthy crops and protect our environment.

How do you find how many electrons are in a atom?

Answers

Answer:

To determine how many total electrons there are, add the amount of charge to the atomic number. In this case, there are fewer protons than electrons. For example, N 3- has a -3 charge which means it has 3 more electrons than a neutral nitrogen atom. Nitrogen’s atomic number is 7, therefore this ion has 10 electrons.
