What will happen if we drink liquid nitrogen?

Answers

Answer 1
Because of its low temperature liquid nitrogen can be extremely damaging to body tissue, causing frostbite and cryogenic burning on contact. If ingested it can lead to severe internal damage, destroying tissue in the mouth and digestive tract.

and the rxn is known as neutralisation rxn

Answer:

When an acid and a base are placed together, they react to neutralize the acid and base properties, producing a salt. Acid-base reactions that do not occur in water usually also produce salts, but they may also produce complex ions.

Explain whether changing the ratio of baking soda and vinegar changes the amount of carbon dioxide produced. Include the evidence you used to reach your conclusion.

Answers

On changing the ratio of baking soda and vinegar changes the amount of carbon dioxide produced is true, because each species will depends on both reactants.

What is chemical reaction?
Chemical reactions are those reactions in which reactants are mixed with each other for the formation of new product.

Chemical reaction between baking soda and vinegar is shown below in the attached image in which the formation of carbon dioxide, water and sodium acetate takes place. So the formation of carbon dioxide depends on the baking soda and baking soda reacts with vinegar to form sodium acetate so change in the ratio will changes the amount of carbon dioxide.

Hence on changing the ratio of reactants and vinegar changes the amount of carbon dioxide.

Which of these is an example of an example factor which affects the earths climate?
A - Decrease in the suns energy.
B - Warm and cold ocean currents.
C - Increase in atmospheric dioxide.
D - Release of dust during volcanic eruption

Answers

Answer:

D- Release of dust during volcanic eruption

Explanation:

During major explosive eruptions huge amounts of volcanic gas, aerosol droplets, and ash are injected into the stratosphere. Injected ash falls rapidly from the stratosphere -- most of it is removed within several days to weeks -- and has little impact on climate change. But volcanic gases like sulfur dioxide can cause global cooling, while volcanic carbon dioxide, a greenhouse gas, has the potential to promote global warming.

answer:

a - decrease in the suns energy.

explanation:

although the other options do discuss climate, temperature, etc., the sun DIRECTLY influences the earth's climate and would most likely affect it on a larger scale. for example, warm and cold ocean currents would affect the temperature of the ocean and could touch bay cities or islands, but they would not dictate the overall climate of the earth :)

Why doesn’t the KHP concentration have to be exactly 0.100M? Explain using complete sentences.

Answers

Answer:

The answer is in the explanation.

Explanation:

The KHP is an acid used as standard in titrations to find concentration of bases as NaOH.

The reaction that explain this use is:

KHP + NaOH → KNaP + H2O

where 1 mole of KHP reacts per mole of NaOH

That means, at equivalence point of a titration in which titrant is NaOH, the moles of KHP = Moles of NaOH added

With the moles of KHP = Moles of NaOH and the volume used by titrant we can find the molar concentration of NaOH.

The moles of KHP are obtained from the volume and the concentration as follows:

Volume(L)*Concentration (Molarity,M) = moles of KHP

If the concentration is more or less than 0.100M, the moles will be higher or lower. For that reason, we need to know the concentration of KHP but is not necessary to be 0.100M.

a 20.5g sample of cleaning detergent contains 8.61g of NH40H.CALCULATE the percentage composition of nitrogen in the cleaning detergent sample​

Answers

Answer:

The mass percentage composition of nitrogen in the sample of the cleaning detergent is approximately 16.78%  

Explanation:

The given mass of the sample of the cleaning detergent, m₁ = 20.5 g

The mass of the ammonium hydroxide, NH₄OH in the detergent, m₂ = 8.61 g

The molar mass of NH₄OH = 35.04 g/mol

The molar mass of nitrogen, N = 14.01 g/mol

Therefore, the mass, m₃ of nitrogen, N, in 8.61 g of ammonium hydroxide, NH₄OH, is found as follows;

m₃ = (14.01/35.04) × 8.61 g = (402,087/118,800) g ≈ 3.44 g

The mass of nitrogen, N, in the ammonium hydroxide, NH₄OH, contained in the 20.5 g sample of the cleaning agent, m₃ ≈ 3.44 grams

The percentage composition of nitrogen in the sample of the cleaning detergent, %N is given as follows;

[tex]\% Composition = \dfrac{Mass \ of \ component}{Total \ mass \ of \ cleaning \ detergent} \times 100[/tex]

Therefore;

%N ≈ ((3.44 g)/(20.5 g)) × 100 ≈ 16.78 %

The percentage composition of nitrogen, %N ≈ 16.78%.

In an exothermic reaction, heat is
released into the surroundings. How does this affect entropy?
particles in the surroundings move slower and have decreased entropy.
• B. The particles in the surroundings move faster and have increased entropy.
•C. The particles in the surroundings move
surroundings move slower and have increased entropy.
• D. The entropy is not affected by this.

Answers

Answer:

B. the particles in the surroundings move faster and have increased entropy

Explanation:

An exothermic process releases heat, causing the temperatures of the surroundings to increase. Entropy increases as temperature increases. Since an exothermic reaction releases heat to the surroundings, molecules in the surroundings will begin to move faster because they will absorb more energy, which increases their kinetic energy. An increase in temperatures means that the particles of the surroundings have greater kinetic energy. The faster moving particals have more disorder than particles that are moving more slowly at a lower temperature. Entropy is interpreted as the degree of disorder/randomness.

What is the mass of the block of iron that has 10 cm 5 cm and 2 centimeters

Answers

Answer:

787.4g

Explanation:

The dimensions of the iron block is given as follows;

L = 10cm, B = 5cm, H = 2cm

Volume = L × B × H

Volume = 10 × 5 × 2

Volume = 100cm³

Density of iron metal = 7.874 g/cm³

Using the formula;

Density = mass/volume

Mass = density × volume

Mass = 7.874 × 100

Mass of iron = 787.4g

Formal charge is calculated by assigning each atom _____ the bonding electrons that it shares. Oxidation number is determined by assigning all the shared electrons of a particular bond to the atom with the _____ electronegativity. Multiple choice question. half; higher half; lower all; lower all; higher

Answers

Answer:

A). half, higher

Explanation:

The Formal charge is elaborated as the 'allocated charge to a molecules' atom' on the basis of the assumption that the electrons present in the chemical bond are equally split among the atoms. It is estimated by 'halving the no. of bonding electrons that encircle the atom.

While Oxidation number is characterized as the 'hypothetical charge of an atom that is present within a molecule.' It is also defined as 'the actual number of lost or gained electrons or the rate at which the electrons are gained or lost by an atom to develop a chemical bond along with the other atom.' It is calculated by allocating or sharing the electrons having the higher electronegativity belonging to a specific bond with the other. Thus, option A is the correct answer.
