A mineral breaks into cubes when struck with a rock hammer. It also leaves a red trail when scraped against an unglazed porcelain plate.

Which of the mineral's properties are being measured?

Choose the two correct answers.


streak

color

cleavage

hardness

Answers

Answer 1

The two properties which can be measured from the given information are streak and cleavage of the mineral.

What are minerals?

Minerals are naturally forming inorganic substances having crystal structure and metallic characteristics. They have a definite chemical composition and  homogeneity.

Streak is the color of powder form of mineral and cleavage is how the mineral cleave when we cut through a plane.  Hardness says how much hard the solid is.

When the mineral breaks into cubes when struck with a hammer, we measure its cleavage properties. The red trail on scrapping indicates the streak of the mineral.

Hence, the two properties we can measure from breaking by hammer and scrapping by an unglazed porcelain are its cleavage and streak.

Air masses that form over large bodies of water are moist. What process determines the amount of moisture in an air mass?

Answers

Answer:

I don't know if this is right but try it. The amount of water vapor in the air is called absolute humidity. The amount of water vapor in the air as compared with the amount of water that the air could hold is called relative humidity. This amount of space in air that can hold water changes depending on the temperature and pressure.

Write a balanced equation for each of the acid-base reaction given below.a. Aqueous sulfuric acid with aqueous potassium hydroxide.

Answers

Answer:

H2SO4 + 2KOH => K2SO4 + 2H2O

Explanation:

The acid-base reaction is a type of chemical reaction that involves the exchange of hydrogen ions.

The acid-base reaction between aqueous sulfuric acid ( H2SO4 ) and aqueous potassium hydroxide (KOH) is a neutralization reaction that results in potassium sulfate and water.

sulfuric acid + potassium hydroxide => potassium sulfate + water

So, the balanced equation for this reaction is as follows:

                  H2SO4 + 2KOH => K2SO4 + 2H2O

Hence, the correct answer is "H2SO4 + 2KOH => K2SO4 + 2H2O".

In a certain chemical reaction, the bond energy of the products is 67 kJ and
that of the reactants is 52 kJ. Because energy is conserved, how much
potential energy does the system release or absorb?
O A. The reaction uses up 15 kJ of energy from the reaction system.
B. The reaction creates 15 kJ of energy when bonds form.
C. The reaction system absorbs 15 kJ of energy from the
surroundings.
O D. The surroundings absorb 15 kJ of potential energy.

Answers

D. The surroundings absorb 15 kJ of potential energy.

Further explanation

Chemical bonds = potential energy

ΔH reaction from bond energy is a breaking and forming reaction of the 2 reacting molecules

Can be formulated:

ΔH rxn =  ∑ the energy of the reagent bonds broken - ∑ the energy of the bonds formed by the product

The bond energy of the products is 67 kJ and reactants 52 kJ

[tex]\tt \Delta H_{rxn}=52-67=-15~kJ[/tex]

ΔH = negative ⇒The reaction is exothermic(releases heat to surrounding)

How many grams of glycine amide should be added to 1.00 g of glycine amide hydrochloride to give 100 mL of solution with pH 8.00

Answers

Answer:

0.4235 g of glycine amide should be added

Explanation:

From the given information:

The equation of the reaction can be illustrated as:

[tex]BH^+ \to B^+ + H ^-[/tex]

where:

mass of glycine amide hydrochloride = 1.00 g

Suppose x be the amount of (in grams) of glycine amide that is required to be added; Then:

[tex][BH^+] = \dfrac{1.00 \ g}{110.54 \ gmol \times 0.100 L}[/tex]

[tex][BH^+]=[/tex] 0.0905 M

So, For [B} i.e, for glycine amide

[tex][B] = \dfrac{x \ g}{74.083 \ gmol \times 0.100 L}[/tex]

[B] = 0.135x  M

[tex]\dfrac{[B]}{[BH^+]}=\dfrac{0.135x \ M}{0.0905 \ M }}[/tex]

[tex]\dfrac{[B]}{[BH^+]}=1.49x[/tex]

The log of the above question can be computed as:

[tex]log _{10}\dfrac{[B]}{[BH^+]}=log _{10}1.49x[/tex]

[tex]pH = pK_a + log _{10} \dfrac{[B]}{[BH^+]}[/tex]

8.00 = 8.20 + [tex]log _{10}(1.49x)[/tex]

8.00 - 8.20 = [tex]log _{10}(1.49x)[/tex]

-0.20 = [tex]log _{10}(1.49x)[/tex]

1.49 x = [tex]10^{-0.20}[/tex]

1.49 x = 0.631

x = 0.631/1.49

x =  0.4235 g
