What amino acid would you end up with if you deleted the c from the second reading frame?

Hydrogen peroxide (H2O2) readily decomposes to form water and oxygen gas: 2H2O2(aq) → 2H2O(l) + O2(g) What concentration of hydr

Anastaziya [24]

Hydrogen peroxide is a powerful oxidizer. When exposed to sunlight it quickly decomposes to form water and oxygen as given by the following equation.

2H2O2(aq) → 2H2O(l) + O2(g)

Hydrogen peroxide is commercially available as a 30% w/w solution, which is the concentration that would facilitate the above reaction. This implies that the concentration would be 30 g of H2O2 in 100 g of the solution.

There are several hazards associated with the chemicals in the qualitative analysis experiment. for each chemical, identify the

Ilia_Sergeevich [38]

You can determine the hazards of these chemicals by looking at their material data safety sheets (MSDS).

1. 0.1 M Ag⁺: Silver compounds are absorbed by skin causing bluish pigmentation. Thus, it causes staining on skin. Also, liquid vapor may be irritating to skin and also moderately toxic when ingested.

2. 0.1 M Ba²⁺: This is mildly toxic when ingested causing stomach irritation, muscle weakness, swelling of organs like brain, liver, kidney and heart.

3. 0.1 M Fe³⁺:Iron is corrosive, has irritating vapor especially to the eyes, and toxic if ingested.

4. 6 M HCl: This is a concentrated strong acid, so it is corrosive, has irritating vapors, flammable and toxic when ingested.

5. 6 M H₂SO₄: This is also a concentrated strong acid. Moreover, it is a strong oxidizing agent. So, its hazards include: corrosive, has irritating vapors, toxic when ingested and causes staining on skin.

6. 6 M HNO₃: This is a concentrated strong acid, so it is corrosive, has irritating vapors, flammable and toxic when ingested.

7. 7.5 M NH₃: This is a weak base. It is characterized for its pungent odor. This is corrosive, has irritating vapors, toxic if ingested, and flammable.

Which is formed by positive ions from a base and negative ions from an acid? a. Salt b. Vinegar

max2010maxim [7]

The formation of salt takes place by the sharing of positive ions from a base and negative ions from an acid.

This is based on the concept and principles of neutralization. The process of neutralization is the name of a chemical reaction between an acid and a base.

Hence, the correct option is a.

pH refers to a measure of how acidic or basic a solution is.

A pH is a measure of how basic or acidic a substance is. pH has a range of 0-14. A pH greater than 7 means the substance is basic.

A pH less than 7 means the substance is acidic. When the pH is exactly 7 that indicates that the substance is neutral.

Hence, the correct optiion is a.

The pH of a solution that has the same number of hydrogen ions as hydroxide ions is 7.

Hence, the correct option is c.

Baking soda has the greatest number of hydroxide ions.

Thus is because of the pH is 9. So, it will be more basic.

Hence, the correct option is a.

Hydrochloric acid will be least likely to completely dissolve in water.

Hence, the correct option is a.

Antacid is taken to get relieve from heartburn describes that the antacid is acidic and will raise the pH of the esophagus.

Hence, the correct option is c.

Acids measure below 7 describes the pH scale.

Hence, the correct option is a.

The order of these solutions from strong acid to strong base is

Ammonia>battery acid>stomach acid>antacid>baking soda.

What is the sequence of energy transformations that occur in a nuclear reactor?

GuDViN [60]

Answer:

option (B) is correct

Explanation:

In case of nuclear reactors first the nuclear energy is emitted due to the nuclear fission of heavy elements.

This nuclear energy is emitted in the form of heat energy.

This heat energy is used to rotate the turbines, that means it is converted in the form of mechanical energy and then finally this mechanical energy is converted into electrical energy.

a 4.18 g sample of a hydrocarbon is combusted in a bomb calorimeter that contains 974 g of water. the temperature of the water i

lys-0071 [83]

The heat of the reaction, in kJ, when 4.18 g of the hydrocarbon are combusted 775.70 kJ.

The heat energy is given as :

q = m c ΔT + Ccal ΔT

q = ( 974 g× 4.184 ×6.9) + 624 ×6.9

q = 32424.59 J

moles of hydrocarbon = 0.0418 mol

heat of combustion = 32424.59 J / 0.0418 mol

= 775707.89 J

= 775.70 kJ

Thus, A 4.18 g sample of a hydrocarbon is combusted in a bomb calorimeter that contains 974 g of water. the temperature of the water increases by 6.9 °C when the hydrocarbon is combusted. the calorimeter constant for the calorimeter was determined to be 624 J/°C. what is the heat of the reaction is 775.70 kJ.
