Answer:

The correct answer is option D, that is, breccia.

Explanation:

The clastic sedimentary rocks, which are formed of large angular pieces are termed as breccia. The gaps in between the large angular pieces are occupied with a matrix of smaller constituents and a mineral cement, which holds the rock together. The formation of breccia takes place when the angular and dissociated pieces of minerals or rock debris gather.

Answer:

D. Brecci

The pattern of the rock below resembles the distinct pattern of brecci.

The pattern of conglomerate usually appears to be more round peices in the rock.  The pattern of brecci has a more shard like appearance.

14.2 grams of Na2SO4 is dissolved in water to make a 2.50 L
Trava [24]

Answer:

0.04 M

Explanation:

Given data:

Mass of Na₂SO₄= 14.2 g

Volume of solution = 2.50 L

Molarity of solution = ?

Solution:

Number of moles of Na₂SO₄:

Number of moles = mass/ molar mass

Number of moles = 14.2 g/ 142.04 g/mol

Number of moles = 0.1 mol

Molarity :

Molarity = number of moles of solute / volume of solution in L

Molarity = 0.1 mol / 2.50 L

Molarity = 0.04 M

Calculate ΔG o for the following reaction at 25°C: 3Mg(s) + 2Al3+(aq) ⇌ 3Mg2+(aq) + 2Al(s) Enter your answer in scientific notat
larisa [96]

Answer:

-3.7771 × 10² kJ/mol

Explanation:

Let's consider the following equation.

3 Mg(s) + 2 Al³⁺(aq) ⇌ 3 Mg²⁺(aq) + 2 Al(s)

We can calculate the standard Gibbs free energy (ΔG°) using the following expression.

ΔG° = ∑np . ΔG°f(p) - ∑nr . ΔG°f(r)

where,

n: moles

ΔG°f(): standard Gibbs free energy of formation

p: products

r: reactants

ΔG° = 3 mol × ΔG°f(Mg²⁺(aq)) + 2 mol × ΔG°f(Al(s)) - 3 mol × ΔG°f(Mg(s)) - 2 mol × ΔG°f(Al³⁺(aq))

ΔG° = 3 mol × (-456.35 kJ/mol) + 2 mol × 0 kJ/mol - 3 mol × 0 kJ/mol - 2 mol × (-495.67 kJ/mol)

ΔG° = -377.71 kJ = -3.7771 × 10² kJ

This is the standard Gibbs free energy per mole of reaction.

What do enzymes do to chemical reactions in cells?
romanna [79]

Answer:

Enzymes are homogenous, thermolabile,biological catalyst that increases the reaction rate of a chemical reaction.

Explanation:

Enzymes are used as catalyst in many biochemical reactions.Enzymes basically interact in a complementary fashion with the transition state of the reaction thus helping to decrease the energy barrier called activation energy.Thus enzymes helps to stimulate  the velocity of biochemical reaction.

      It is very important point to note that enzymes do not affect the reaction equilibrium.
