Answer:

A) long distance and long travel time.

Explanation:

Sedimentary rocks are the rocks which are created by the accumulation or the deposition of minute particles as well as subsequent cementation of the  mineral or the organic particles on floor of the bodies of the water at the  surface of the Earth.

Sediment Maturity is the duration of the time that sediments have been in sedimentary cycle. <u>Texturally, mature sediments are that which are well rounded, (the process of rounding for the sediments increases with the transport distance as well as the time) as well as well sorted (the process of sorting for the sediments gets better as the larger clasts are astray and the smaller clasts are carried away , which also means the sediments travel longer distance).</u>

You dissolve 14 g of Mg(NO3)2 in water and dilute to
mart [117]

Answer:

0.127M

Explanation:

Molarity of a solution = number of moles (n) ÷ volume (V)

Molar mass of Mg(NO3)2 = 24 + (14 + 16(3)}2

= 24 + {14 + 48}2

= 24 + 124

= 148g/mol

Using the formula, mole = mass/molar mass, to convert mass of Mg(NO3)2 to mole

mole = 14g ÷ 148g/mol

mole = 0.095mol

Volume = 750mL = 750/1000 = 0.75L

Molarity = 0.095mol ÷ 0.75L

Molarity = 0.127M

For the skeletal chemical equation BF3(g) + NaH(s) → B2H6(g) + NaF(s) what is the coefficient of B2H6 in the balanced equation?
KonstantinChe [14]

Answer:

Coefficient in front of the B_2H_6  in the balanced equation - 1

Explanation:

The unbalanced Chemical equation is shown below as:-

BF_3+NaH\rightarrow B_2H_6+NaF

On the left hand side,  

There are 1 boron atom and 3 fluorine atoms and 1 sodium and hydrogen atoms.

On the right hand side,  

There are 2 boron atoms and 6 hydrogen atoms and 1 sodium and fluorine atoms.

Thus,  

leftside, BF_3 must be multiplied by 2 to balance boron and right side, NaF must be multiplied by 6 to balance fluorine. Left side, NaH must be multiplied by 6 to balance sodium and hydrogen atoms.

Thus, the balanced reaction is:-

2BF_3+6NaH\rightarrow B_2H_6+6NaF

<u>Coefficient in front of the B_2H_6  in the balanced equation - 1</u>

Which best describes how heat energy moves within the system?
Radda [10]

Heat can be transferred from one place to another by conduction in solids, convection of fluids like liquids or gases, and radiation. A temperature difference in a system causes heat to move from higher to lower temperatures
