The law of conservation of mass is must be applied when cooking.

<h3>What is conservation of mass?</h3>

Law of conservation of mass states that mass of any substance will change into another form without any loss of mass, means destroying of mass is impossible.

When we cook food then mass of conservation is applied there, for example we are boiling pulses with water then in that case the amount of formed liquid pulses is equal to the initial mass of solid pulse with water.

Hence law of conservation of mass is applicable during cooking.

Lithosphere: Odd one out . Analyze each part of the rectangle. One of the parts will be different from the others. Shade the par
patriot [66]

The characteristics of the lithosphere found that the frame that is out of sequence is:  

       last frame: Iron

The lithosphere is the upper part of the Earth, it is composed of two parts: the crust and the upper part of the mantle, up to the ionosphere, an area of ​​material in a plastic state.

The lithosphere is the most important part for since all the life processes on the planet occur in it, the depth of the lithosphere is greater in the continental part about 250 km than in the oceanic part 150 km, this is It is because it is floating above the stratosphere.

Let's analyze each part of the picture

1. Rigid rocks in the upper part of the mantle.

The lithosphere is the coldest part of the plant, which is why the rocks have solidified, forming a rigid layer of rocks that floats on the mantle.

2. Crust.

It is another name given the uppermost part of the lithosphere, it is formed by a solid area,

3. Tectonic plates.

The lower part of the lithosphere is on an area in a very hot platic state, therefore there is a thermal gradient between the convection current of the asthenosphere and the thermal conduction of the lithosphere, these thermal gradients create breaks or divisions in the upper layer that we call plate tectonics

4.) solid crust of the Earth

The lithosphere is by definition the solid part of the Earth, which is why it is also called solid crust, but not rigid.

5) Continents.  

They are the highest parts of the lithosphere, they are above the average height of the oceanic that forms the liquid part that fills the lower spaces of the lithosphere, in general it is formed by rocks of granite composition

6) Earthquakes

The plates of the lithosphere can move between it, in some cases these plates are locked (stopped) accumulating energy at some point the rocks that form part and the plates move abruptly this movement is called an earthquake

7) Volcanoes

The lower part of the lithosphere is hotter, in some parts where the upper rock is more fragile, this heat can fragment them, which is why the molten rock called magna has an exit path towards the earth's surface, in general the fragmentation processes and rupture is accompanied by high pressures that make the surface rise in height, these structures are called volcanoes, the vast majority are near the contact zone of the tectonic plates,

8) Iron  

This is a chemical element that is one of the constituents of the lithospheres, but it is not an essential part of its structure. Iron, for being a heavy element, is believed to be fundamentally in the Earth's nucleus, in the lithosphere it only forms 4.7% of its structure. This is why this box is out of sequence of the second rectangle

Consequently with the characteristics of the lithosphere found that the frame that is out of sequence is:

              last frame: Iron

Determine the amount of heat energy in joules required to raise the temperature of 7.40g of water from 29.0OC to 46.0 OC.
valina [46]

Answer: The amount of heat energy in joules required to raise the temperature is 526 Joules

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q=m\times c\times \Delta T

Q = Heat absorbed = ?

m= mass of substance = 7.40 g

c = specific heat capacity = 4.184J/g^0C

Initial temperature of the water = T_i = 29.0°C

Final temperature of the water = T_f  = 46.0°C

Change in temperature ,\Delta T=T_f-T_i=(46.0-29.0)^0C=17.0^0C

Putting in the values, we get:

Q=7.40g\times 4.184J/g^0C\times 17.0^0C

Q=526J

The amount of heat energy in joules required to raise the temperature is 526 Joules

Answer:

Response is below

Explanation:

The different types of mining are underground, surface, placer, and in-situ. Underground mining uses various materials to excavate resources from beneath the surface of the Earth. Surface mining is a category of mining that in which soil and rock overlying the mineral deposit are removed. Placer mining is the mining of stream bed deposits for minerals. In-situ mining is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit.

How many oxygen (O) atoms are involved in this chemical reaction?<br><br> 2Fe(OH)3 — Fe2O3 + 3H20
kenny6666 [7]

Answer:

6 oxygen atoms

Explanation:

From the equation,

2Fe(OH)₃ → Fe₂O₃ + 3H₂O

From the reactant (left hand side) we have 2 moles of Fe(OH)₃ having (2 * 3 = 6) atoms of oxygen and decomposed to give Fe₂O₃ which contains 3 atoms of oxygen and 3 moles of water that also contains 3 atoms of oxygen.

Since the number of oxygen participating in the reaction is independent on the product (not a reversible reaction) then the total number of oxygen atoms participating in the reaction is 6
