Conglomerate rocks are colorful and attractive; however, it is rarely used as ornamental stone for interior use because of its unreliable physical strength and durability.
Conglomerate has very few commercial uses, though it can be crushed to make a fine aggregate that can be used when a low-performance material is needed.
Conglomerate forms where sediments of rounded clasts at least two millimeters in diameter accumulate. Because of the large size of the clasts, it takes a very strong water current to transport and shape the rocks. As they tumble through the running water or moving waves, they form their rounded shape.
These rocks can be found in sedimentary rock sequences of all ages. They probably make up less than one percent by weight of all sedimentary rocks.

In the following reaction, how many grams of H2O are produced if 2.00 g of N2H4 react? N2H4 + 3 O2 ---> 2NO2 + 2H2O
Answers
Answer:
2
Explanation:
From this equation, 2 grams are produced.
The mass of H₂O produced from the reaction is 2.25 g
We'll begin by calculating the mass of N₂H₄ that reacted and the mass of H₂O produced from the balanced equation.
N₂H₄ + 3O₂ —> 2NO₂ + 2H₂O
Molar mass of N₂H₄ = (2×14) +(4×1) = 32 g/mol
Mass of N₂H₄ from the balanced equation = 1 × 32 = 32 g
Molar mass of H₂O = (2×1) + 16 = 18 g/mol
Mass of H₂O from the balanced equation = 2 × 18 = 36 g
SUMMARY
From the balanced equation above,
32 g of N₂H₄ reacted to produce 36 g of H₂O.
Finally, we shall determine the mass of H₂O produced by the reaction of 2 g of N₂H₄From the balanced equation above,
, 32 g of N₂H₄ reacted to produce 36 g of H₂O.
Therefore,
2 g of N₂H₄ will react to produce = (2 × 36) / 32 = 2.25 g of H₂O
Thus, the mass of H₂O produced from the reaction is 2.25 g

What is the cost to drive to Los Angeles from San Francisco a distance of 405 miles if the cost of gasoline is $2.90 a gallon and the car get 25 miles per gallon of gas?
Answers
Answer: $46.98
Explanation:
The distance to drive to Los Angeles from San Francisco is 405 miles. Since the car get 25 miles per gallon of gas, for 405 miles, the car will use:
= 405/25 = 16.2 gallons
Since the cost of gasoline is $2.90 a gallon and the car will use 16.2 gallons. The cost will be:
= $2.90 × 16.2 gallons
= $46.98

A.You would see an explosive chemical reaction.
B.The acid would destroy the base.
C.The base would destroy the acid.
D.You'd wind up with a pH-neutral salt and water.
Answers
Answer:
D
Explanation:
When you mix a strong acid and a strong base : ( D ) You will wind up with a pH-neutral salt and water
The mixture of a strong base and an equally strong acid results in a neutralization reaction, because at the point of equivalence the base and acid will completely neutralize each other.
The mixture solution will have a pH value of 7 and the end products will an ionic salt and water.
Hence we can conclude that When you mix a strong acid and a strong base , you will wind up with a pH-neutral salt and water.

There is free rotation about the carbons of ethane but not th
of ethane. This is due to the fact that
A. the carbons in ethane are round
Balkenes do not rotate
C. the carbons in ethane are linked by double bonds
D. the carbon in ethane are smaller than those of ethane
Answers
Answer:
C. the carbons in ethene are linked by double bonds
Explanation:
The reason for the lack of free rotation about the carbons of ethene is that they are linked with with double bonds.
In single bonds afforded with the ethane compound, there is free rotation.
The double bonds confer a special restriction on the rotational potential of the bonded atoms round the carbon.

A motorcycle starts at rest and moves a distance of 460m .
If it has constant acceleration of 4m55 m/s2 what is its final velocity
Answers
Answer:
The final velocity of the motorcycle is 64.7 m/s
Note: Since the value for the acceleration of the motorcycle is not clear, it is assumed to be 4.55 m/s² in the calculation
Explanation:
Using the equation of motion that contains all the given values in the question: v² = u² + 2as
where v is final velocity; u is initial velocity; a is acceleration; s is horizontal distance
v = ?, u = 0 (since the motorcycle starts from rest), a = 4.55 m/s², s = 460 m
v² = 0² + 2 * 4.55 * 460
v² = 4186
take square root of both sides
v = 64.7 m/s
Therefore, the final velocity of the motorcycle is 64.7 m/s

C

D
The particles of matter are arranged in different ways for the different state.
Answers
Answer:
D .The particles of matter are arranged in different ways for the different state.
Explanation:
The kinetic molecular theory is used to explain the forces between molecules and the energy the molecules possesses.
One of the key postulate of this theory is that;
The particles of molecules are continual state of motion. They posses kinetic energy. In gas, the particles are random and moves in a straight line motion. Liquids are less random and only slide past one another. Solids have a restricted space and the molecules are free to move about.Therefore, we can see that the particles of matter are arranged in different ways for different state.
