Explanation: Chemical changes  cause a substance to change into an entirely substance with a new chemical formula. And chemical changes are also known as chemical reaction.

Answer:

omggggggggg that is sooo confusing what grade are you in?

This problem is providing information about the states of matter and a given diagram showing a molecular arrangement it has. Thus, we can start off by analyzing the attached file, which shows molecular arrangements and movements each state exhibits.

Solids are quite organized so that they are able to form molecular networks in which molecules vibrate but do not displace anywhere. Liquid molecules are close enough to have small movements and vibrations but are not able to form any organized network.

Gases, however, exhibit no molecular organization but large movements inside the container whose walls the gas constantly crash against. Plasma do not have any order neither yet it contains ions.

In such a way, since the given diagram do not have any apparent order or ion, we infer this is about a gas that moves into the container and crash against its walls.

Explanation:

The percentage error of a certain measurement can be found by using the formula

[tex]P(\%) = \frac{error}{actual \: \: number} \times 100\% \\ [/tex]

From the question

actual density = 0.7 g/cm³

error = 0.7 - 0.63 = 0.07

So we have

[tex]p(\%) = \frac{0.07}{0.7} \times 100 \\ = 10[/tex]

We have the final answer as

Explanation:

Fossilized marine creatures found at the top of the Himalayan Mountains provide evidence for a scientific theory of plate tectonics. Therefore, option (D) is correct.

Plate tectonics can be explained as the Earth's lithosphere being made of a large number of tectonic plates that have been slowly moving since about 3.4 billion years ago.

The lithosphere is broken into 7 or 8 major plates and many minor plates or "platelets". These plates meet, and their relative motion evaluates the kind of plate boundary: convergent, transform, or divergent.

Mountain-building, Earthquakes, volcanic activity, and oceanic trench formation take place along these plate boundaries. The relative annual movement of the plates ranges from 0 to 10 cm.

Tectonic plates are comprised of the oceanic and the thicker continental lithosphere. The process of subduction which is actually one plate moving under another carries the edge of the lower plate down into the mantle along convergent boundaries.

Pebbles, Shells, and marine fossils found in the limestone beds of the tallest Himalayas Mountains give evidence of the theory of plate tectonics.

can someone please do this and put the answers below !!!!

Explanation:

Answer:

Depends on if the atoms have the same amount of atomic mass and if they have the same amount of ions, or none at all.

Explanation:

They can be the same atom, but if they don't have the same amount of protons, electrons, and neutrons, they aren't identical.

Answer:

2Br(aq)+2HNO2(aq)+2H(aq)------->Br2(l)+2NO(aq)+2H2O(l)

Explanation:

The given redox reaction can be balanced in acidic medium as follows:

[tex]\rm 2 Br^{-} + HNO_{2} + H^{+} \rightarrow Br_{2} +NO + H_{2}O[/tex]

A reaction involving both oxidation and reduction is called redox reaction. One species is getting oxidized here whereas another species reduces. The substance which is oxidized  is called oxidant and the reduced species is called reductant.

In the given reaction of bromine gas with nitrous acid, bromine oxidizes from -1 to zero whereas nitrogen reduces from +3 to +2. The reaction can be occurred in acidic medium.

The redox reaction written in acidic medium involves H+ and water properly added to either sides. The balanced redox reaction of the given one in the acidic medium is thus as written above.

#SPJ2

Answer:

Explanation:

The formula is density = mass÷volume

Values given are:

mass = 5.910g  and

diameter = 10.0 mm = 1cm

so, we need to find the volume first.

Volume of a sphere is (4/3)πr³

thus, V = 4.189 cm³

Density = mass ÷ volume

density = 5.910 ÷ 4.189

= 1.411 g/cm³

Answer:

[tex]V_2=35.68\ L[/tex]

Explanation:

Initial volume, V₁ = 300 L

Temperature, T₁ = 227°C

New temperature, T₂ =  27°C

We need to find the volume of gas occupied when the temperature is 27°C.

It is based on Charle's law. A/c to Charle's law,

[tex]V\propto T[/tex] (at constant pressure)

[tex]\dfrac{V_1}{V_2}=\dfrac{T_1}{T_2}\\\\V_2=\dfrac{V_1T_2}{T_1}\\\\V_2=\dfrac{300\times 27}{227}\\\\V_2=35.68\ L[/tex]

Hence, the new volume is 35.68 L.
