Answer:

Explanation:The silica tetrahedron is a molecule containing four oxygen atoms and one silicon atom. It resembles a triangular pyramid, with the silicon atom located in the middle and one oxygen atom located at each of the four corners.

The structure of olivine is described as isolated tetrahedral because each tetrahedron is bonded to either a magnesium ion or an iron ion.

Although some minerals always appear the same color, many vary in color due to trace elements within the mineral. These trace elements can alter the mineral’s coloring.

Minerals with a metallic luster do not allow light to pass through. Minerals with a nonmetallic luster do allow light to pass through.

In minerals, cleavage refers to breaks that occur along a specific plane. Fractures refer to irregular breaks.

If the density of a certain oil is 0.8gcm3. What is the mass of 10 cm3 sample of this oil?

kirill115 [55]

The density is:

d=m/V

Applying the values in the formula:

0.8 g/cm³ = m / 10 cm³

Solving for m:

m = 8 g (with one significant figure)

A piece of metal has a volume of 0.250 hogsheads and a mass of 54.424 kg. calculate the density of the metal in pennyweights per

drek231 [11]

Density is a value for mass, such as kg, divided by a value for volume, such as m3. Density is a physical property of a substance that represents the mass of that substance per unit volume. We calculate the density using the equation

Density = mass / volume

The units asked for the density would be pennyweights per peck. The conversion factors are as follows:

1 pennyweight (pw) = 1.55 grams
1 hogshead (hh) = 238.5 liters 
1 peck = 9.091 liters

We calculate as follows:

mass = 54.424 kg ( 1000 g / 1kg ) ( 1 pennyweight / 1.55 g ) = 35112.26 pennyweight
volume = 0.250 hogsheads ( 238.5 L / 1 hogshead ) ( 1 peck / 9.091 L ) = 6.56 peck

Density = 35112.26 pennyweight / 6.56 peck = 5353.55 pw / peck

Consider this reaction: HCO3− H2S → H2CO3 HS− Which is the Bronsted-Lowry base? H2S HCO3- HS– H2CO3.

motikmotik

Bronsted Lowry base is the species that accepts or acquires protons from other species of the reaction. $\rm HCO_{3}^{-}$ is the Bronsted-Lowry base.

<h3>What is a Bronsted-Lowry base?</h3>

In an acid-base reaction, the element or the compound capable of obtaining a proton or a hydrogen atom is called a Bronsted-Lowry base.

According to the theory, the base will accept proton and acid will donate an electron. The reaction of the acid and base is shown as,

$\rm HCO_{3}^{-} + H_{2}S \rightarrow H_{2}CO_{3} + HS^{-}$

From the reaction, it can be said that bicarbonate is the Bronsted-Lowry base as the number of hydrogen or protons are increasing in the product.

Therefore, option b. $\rm HCO_{3}^{-}$ is the Bronsted-Lowry base.
