You can identify the aldehyde from acidic potassium permanganate. Purple colour of acidic potassium permanganate is changed to colourless because aldehyde is oxidized by acidic potassium permanganate.

Potassium atom would not bond with a calcium atom because two metals because they are not capable of accepting electrons.

This is referred to as a substance with high electrical conductivity, luster, and malleability, which readily loses electrons to form positive ions known as cations.

The formation of chemical bonds in a reaction requires a change in electron distribution which can only be possible when one of the elements participating in the reaction can accept electrons and is therefore the reason why two metals such as potassium and calcium atom can't form a reaction but two non metals can.

Explanation:

Weathering and erosion on the Earth's surface break down volcanic rock becoming pebbles, sand, as well as mud, resulting in sedimentary rock.

Sedimentary rock, rock generated at or near the Earth's surface as a result of sediment deposition and lithification or precipitation into solution at typical surface temperatures.

Sedimentary rocks are among the most frequent on the Earth's surface, although they make up just a minuscule portion of the crust, which would be dominated by metamorphic and igneous rocks.

Weathering and erosion on the Earth's surface break down volcanic rock becoming pebbles, sand, as well as mud, resulting in sediment that collects in basins just on Earth's surface. The image for the formation of sedimentary rock is given below.

Therefore, weathering and erosion on the Earth's surface break down resulting in sedimentary rock.

Answer:

Some of the energy from the electrons is used to pump hydrogen ions across the membrane, creating an electrochemical gradient that drives the synthesis of many more molecules of ATP. In all three stages of cellular respiration combined, as many as 38 molecules of ATP are produced from just one molecule of glucose.

Explanation:

The total bond energy of 2OH bond is 928 kJ/mol

Bond energy is the energy needed to break or form bonds. They are measured in kilojoule per mole (kJ/mol).

Since we are given that the bond energy of O-H is 464 kJ/mol and we require the total bond energy of 2OH. In 2OH, the are two O-H bonds.

So, the bond energy of the two O-H bonds will be twice that of the single O-H bond.

So bond energy of 2OH = 2 × bond energy of O-H = 2 ×  464 kJ/mol

= 928 kJ/mol

So, the total bond energy of 2OH bond is 928 kJ/mol

Answer:

6116g

Explanation:

2SO2(g) + O2(g) + 2H2O(ℓ) −→ 2H2SO4(ℓ)

We want to find the mass in grams of SO2 that is needed to react with 1527 g of O2. First we must convert the grams of O2 to moles of O2 then to moles of SO2 and then to grams of SO2

So first lets find the molar mass of O2

The mass of oxygen according to a periodic table is 15.999

Using this the mass of O2 would be 15.999(2) = 31.988g

Next we need to identify the mole ratio of O2 to SO2

Looking at the equation for 1 mole of O2 there are two moles of SO2

Next we need to find the molar mass of SO2

Again the mass of oxygen is 15.999g and the mass of Sulfur is 32.066

So the mass of SO2 would be 15.999(2) + 32.066 = 64.064g

Now that we have found all the needed conversions :

We can now use dimensional analysis to calculate the answer.

Kindly check the attached image to see the table. ( sorry if its a bit blurry )
Explanation : The conversions are used to cancel out the units to get to the final unit which is gSO2.

Once the units are cancelled out except for the gSO2 we mutliply and divide based off of what the table says to do.
Here first we divide 1527 by 31.988. We than multiply by 2. Finally we multiply by 64.064 to get the final answer which is 6116gSO2

=> Flame is a visible, gaseous region of a fire.

The mass of sodium chloride (NaCl) produced from the reaction when 471 KJ of heat is released is 67.04 g

2Na + Cl₂ —> 2NaCl   ΔH = + 822 kJ

Molar mass of NaCl = 23 + 35.5 = 58.5g/mol

Mass of NaCl from the balanced equation = 2 × 58.5 = 117 g

SUMMARY

From the balanced equation above,

When 822 KJ of heat is released, 117 g of NaCl were produced.

From the balanced equation above,

When 822 KJ of heat is released, 117 g of NaCl were produced.

Therefore,

If 471 KJ of heat is released, then = (471 × 117) / 822 = 67.04 g of NaCl will be produced

Thus, 67.04 g of NaCl were obtained from the reaction

The energy of -91.8 kJ in the reaction equation shows that energy is released so this is an exothermic reaction.

A thermochemical equation is one which just does not only show the reactants and products but also shows the energy absorbed or emitted in the reaction.

We can see from the thermochemical equation; N2(g) + 3H2(g) → 2NH3(g); ΔH = -91.8 kJ that the negative enthalpy implies that  energy is released so this is an exothermic reaction.

Explanation:

For naming alkane molecules follow the following steps

1) Find the longest continuous carbon chain and count the number of carbons

In this structure, it is from the bottom, then up, then to the right. Making a right angle. There is 6 carbons in this chain which means it's a hexane

2) Number the longest carbon chain so the constituents (parts not part of the carbon chain) are connected to the carbon with smallest number possible.

This gives the extra CH3 group connected to carbon 3

The molar mass of M is 40.2 g/mol and the name of the element is Calcium.

35.3g of element M reacted with nitrogen to produce 43.5g of compound M3N2.

3M + N₂→ M₃N₂

Therefore,

let the molar mass of element = x

35.3 g of M = 43.5 g of  M₃N₂

3x g of M = 3x + 28

cross multiply

35.3(3x + 28) = 43.5(3x)

105.9x + 988.4 = 130.5x

988.4 = 130.5x - 105.9x

988.4  = 24.6x

x = 988.4 / 24.6

x = 40.1788617886

x = 40.2

Therefore, the molar mass of M is 40.2 g/mol and the name of the element is Calcium.
