The Grand Colorado River

Explanation:

The state of Colorado consists of a colorado river that goes through the grand canyon. Starting from the rocky mountain region originating in the Gulf of California and entering the colorado plateau this river is 1450 miles long and drains extensively. The natural discharge rate of this river is 16.3 million acre-feet. As 90 % of the river discharge originates in snowmelt.

[rm.02]an igneous rock interacts with wind and water over a long period of time. which of these is most likely formed as a resul
kirill115 [55]
Sediments is most likely to be as a result of the interaction.

As wind and water are both weathering agents that cause the fragments of rocks to loosen,under the pull of gravity the fragments will fall off and sediments will be formed.

Reason why these are incorrect:

Lava and magma- Rocks has to be molten under an extremely high temperature to turn back into magma of lava,as the high
temperature is not present,the formation is impossible.

Metamorphic rock- It requires either high temperature or high pressure to lead to the formation of metamorphic rock, however the conditions are not present, thus this is incorrect.

Details of weathering:
The water would seep into the joints of the igneous rock as it is well-jointed,and carry out chemical weathering.
The materials such as feldspar and mica are nit weather-resistance hence easily loosen after weathering take place,causing the fragments to fall off.

Hope it helps!

3) What is the composition, in atom percent and in weight percent, of an alloy that contains 33 g Cu and 47 g Zn?
Marat540 [252]

Answer: composition in weight percent = 41.25% Cu and 58.75% Zn

Composition in Atom percent = 40.54% Cu and 59.46% Zn

Explanation:

Starting with the composition in weight percent.

Let Mcu= mass of cu and Mzn= mass of zn

%W= weight percent

%Wcu = (Mcu/(Mcu + Mzn)) × 100%

By substituting the values

%Wcu = (33/(33+47)) × 100%

%Wcu = (33/80) × 100%

%Wcu = 41.25%

%Wzn = (Mzn/(Mcu + Mzn)) × 100%

= 47/80 × 100%

%Wzn = 58.75%

Then we can proceed to composition in atom percent

Atomic mass of Cu= Ac = 63.5g/mol

For zn = Az = 65.4g/mol

Atom percent cu = {(%Wcu×Ac)/[(%Wcu×Ac)+(%Wzn×Az)]} × 100%

Substituting the values

= {2619.375/6461.625}×100%

=40.54% Cu

Atom percent zn = {(%Wzn×Az)/[(%Wcu×Ac)+(%Wzn×Az)]} × 100%

={3842.25/6461.625}×100%

=59.46% Zn

Thanks...
