Which two bonds are least similar in polarity?

Select one:
a. I-Br and SiCl
b. B-F and Cl-F
c. C-Cl and Ge-Cl
d. O-F and Cl-F
e. Ga-Cl and I-Br

So,

Given the following reaction:

We want to find the number of moles of water that can be produced from the reaction of 2.0 moles of hydrogen gas is reacted with 2.5 moles of oxygen gas.

First of all, we need to check which of both reactants is the limiting reactant because that reactant is going to generate the product.

To find the limiting reactant, we're going to use the coefficients of the reaction. The equation tells us that per each two moles of H2, one mol of O2 is needed to react. So,

We have 2 moles of H2, but we need 5 moles of H2 to react according to the reaction.

Since we have less amount of what we really need, then, H2 is the limiting reactant.

Now, the moles of water produced will be:

The answer is 2 moles of H2O.

I ordered the tiles from left to right and top to bottom as the numbers kept increasing. The tiles were also organized based on the color and shape that they were. The tiles with the same color and shape were arranged in the same column.

Explanation:

In the modern periodic table, the elements are listed in order of increasing atomic number and elements having similar chemical properties naturally line up in the same column (group).

Based on the quantity as well as shape of each tile, arrange them in the table.

The majority of the time, tiles are thin, square usually rectangular coverings made of durable materials like ceramic, stone, metals, baked clay, or perhaps even glass. They are typically put in place inside an arrangement to cover surfaces including tabletops, borders, floors, walls, and roofs.

In another definition, a tile is indeed a building material or a comparable object, such the rectangular game counters. The word comes taken from the Latin phrase tegula, which means a roof tile made of heated clay. Based on the quantity as well as shape of each tile, arrange them in the table.

Therefore, based on the quantity as well as shape of each tile, arrange them in the table.

The volume of 8.8g of carbon dioxide at STP is 4.38 L.

1 mole of any gas will take up 22.4 L of space at standard temperature and pressure (STP). A balanced chemical equation and the Ideal Gas Law can be used to determine the amount or mass of gas consumed or created in a chemical process.

n = m/M

where m is the molar mass of carbon dioxide and M is its mass in terms of molecules.

Considering that the molar mass of carbon dioxide is 44.01 g/mol:

n = 8.8 g / 44.01 g/mol

n = 0.1998 mol

Next, we can plug in the values of n, R, P, and T into the ideal gas law and solve for V:

V = (nRT)/P

V = (0.1998 mol x 0.0821 L·atm/(mol·K) x 273.15 K) / 1 atm

V = 4.38 L

Chemical treatment of hazardous waste refers to the treatment methods that are used to effect the complete breakdown of hazardous waste. The hazardous waste is chemically processed in chemical treatment to make it less harmful and less toxic.

There are several different chemical treatment methods used to treat hazardous waste, including oxidation, reduction, neutralization, and precipitation. In oxidation, the waste is treated with oxidizing agents to convert the waste into a less harmful form. In reduction, the waste is treated with reducing agents to convert the waste into a less harmful form. In neutralization, an acid or base is added to the waste to neutralize its pH.

In precipitation, a chemical is added to the waste to cause it to precipitate out of solution. Chemical treatment is one of several methods used to manage and dispose of hazardous waste in an environmentally responsible manner.

Answer:

2.5 g of platinum

Explanation:

Recall that a catalyst is a specie added to a reaction system to increase the rate of reaction. A catalyst does not participate in the chemical reaction hence it remains unchanged at the end of the chemical reaction. A catalyst merely provides an alternative reaction pathway by lowering the activation energy of the reaction system. Hence a catalysed reaction usually proceeds faster with less energy requirement than the uncatalysed reaction.

Since the catalyst does not participate in the reactions and remains unchanged at the end of the reaction, the mass of platinum will remain the same (2.5g). The mass can only change if a specie participates in the chemical reaction. Hence the answer.

2.5 g of platinum will there be left in the vessel at the end of the reaction

in order for the wooden to waft in fuel, it needs to have a density much less than the density of fuel and so as for it to sink in ethanol, it must have a greater density than the density of ethanol however ethanol is denser than gasoline therefore if it sinks in ethanol it has to also sink in fuel.

If the wood pressure is much less than the object's weight, the object will sink. So, the piece of timber floats in water whilst located in ethanol it sinks. ethanol is lighter than water so it needs to drift to the floor of the water but this isn't always the actual case. The ethanol in water neither sinks nor floats, alternatively it mixes thoroughly to form a homogenous solution. The purpose of this blending of two solutions is hydrogen bonding between ethanol and water.

Density is a measure of how heavy something is compared to its size. If an item is greater dense than water it will sink while placed in water, and if it's miles much less dense than water it'll float. Density is a functioning asset of a substance and doesn't depend on the amount of substance.

The citric acid cycle is a continuous series of reactions that produces 2 carbon-dioxide molecules, one GTP/ATP molecule, and the  some reduced forms of NADH,  in one turn of the citric acid cycle.

Taking into account only the citric cycle, the two molecules are created in a single turn when the acetyl coA enters the citric acid cycle.

The majority of solar radiation that hits water's surface is reflected back into the atmosphere. Given that land absorbs more solar radiation, both the land's surface and the vegetation it supports retain more heat.

Water absorbs and releases heat more slowly than land because its specific heat is higher than that of dry soil. Due to the high heat capacity of water, large bodies of water often tend to moderate the temperature of neighboring land.
