magnesium nitrate contains chemical bonds that are

Answers

Answer 1

Answer:

Magnesium Nitrate is an ionic compound formed by:

Magnesium;Mg+2 (the cation) and Nitrate NO−3 (the poly-atomic anion).

In order for these two ions to bond, the charges must be equal and opposite. Therefore, it will take:

     two -1 nitrate ions to balance the one +2 magnesium ion.

Explain why the melting temperature of boron trichloride is much lower than that of sodium chloride​

Answers

Boron trichloride has a simple molecular structure,
whereas sodium chloride has a giant ionic lattice
structure. The ionic bonding between oppositely
charged ions in NaCl is stronger than the covalent
intramolecular bonding in BCl3. Therefore, less energy
is required to break the intramolecular covalent bonds in
BCl3, hence a lower melting temperature.

Ammonia is manufactured from nitrogen and hydrogen by the Haber process.
N2(g) + 3H2(g)2NH3(g)
What is the percentage yield when 60 kg of ammonia is produced from 60 kg of hydrogen?
A
5.9%
B
17.6%
с
35.3%
D
50.0%

Answers

Answer:

B

17.6%

Explanation:

1. Percentage yield = (Actual yield/theoretical yield) x 100

2. You know actual yield of ammonia (60kg) so you need to work out theoretical yield.

3. mols of hydrogen = m/mr = 60,000/2 = 30,000 mols.

4. 3:2 ratio so (30,000/3) x 2 = 20,000 mols of Ammonia.

5. Therefore mass of ammonia = mr x mols = 20,000 x 17 = 340,000 grams

6. So percentage yield is (60,000/340,000) x 100 = 17.6

What is the purpose of the chemical ammonia (NH3) in hair dyes?

Answers

Answer: Ammonia, an alkaline chemical, is used to raise the pH level (it's levels of acidity) of our hair during the colouring process. This then lifts the cuticles of the hair fibre and allows the colour to be deposited onto the cortex (the inner part of the hair protected by the cuticles). In hair coloring products, ammonium hydroxide is used to support the lightening action of hydrogen peroxide and to prepare hair to accept color pigments. Alkaline properties of ammonia raise the cuticle and allow peroxide and dye molecules to penetrate the hair shaft. (creds to the internet)

Answers

Answer:

 The correct answer is option A, that is, HCl.  

An acid refers to an ion or molecule possessing the tendency of donating a hydrogen ion or a proton, or alternatively, exhibiting a tendency of producing a covalent bond with a pair of electrons. The aqueous Arrhenius acids exhibit characteristic features that offer a practical illustration of an acid.  

The acids can turn blue litmus paper red, can form aqueous solutions with a sour taste, and reacts with bases and some kind of metals to produce salts. One of the general aqueous acids is HCl (hydrochloric acid) that is found in the stomach and stimulates digestive enzymes.

If the burner doesn't light after several strikes, turn the gas off at the source. Verify that you are generating sparks when striking the striker, and check that the barrel is all the way down and the needle valve is open by the specified amount. If these check out, the problem may be insufficient gas flow.

Saliva, produced by glands in the mouth, plays an important role in the digestion of food. Saliva contains a chemical, called amylase, that breaks down starch in the food we eat. A scientist conducts an experiment to investigate at which temperatures amylase works the best. He hypothesizes that the reaction will occur fastest if the amylase reaction is conducted near the normal human body temperature of 37ºC (degrees Celsius). In order to test his hypothesis, the scientist measures the reaction rate, which is how fast the amylase breaks down the starch at six different temperatures. The reaction rate is rated on a scale of 0 to 10, with 0 meaning no reaction and 10 meaning the fastest reaction. The results are recorded in the data table.

Based on the data, should the scientist accept or reject his hypothesis?

Answers

Answer:

The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily. Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.
