H atoms are both oxidized and reduced. The oxidising agent is a chemical that undergoes oxidation by taking in electrons, which results in a drop in oxidation state.
Which is reduced and oxidized?Redox reactions, also referred to as oxidation-reduction processes, are reactions in which electrons are transferred from one species to another. An oxidised species is one that has lost electrons, whereas a reduced species has gained electrons.Oxidation is the process in which a reactant loses electrons during a reaction. Reduction is the term used to describe a reaction in which a reactant picks up electrons. This happens frequently when acid and metals interact.

the compound Xcl4 contains 75% cl by mass what is element x
Answers
The X element in the compound = titanium
The chlorine has the molecular weight = 35.5 g/mol
In the compound of Xcl4 , there are four atoms of chlorine molecules who occupy 0.75 of total weight.
The weight of all 4 chlorine atoms = 4×35 = 140 g/mol
Now the total weight of the all chlorine atoms in the compound = 140/0.75
Now the total weight of the compound = 186.66≈ 187
The weight of X element = 187 - 140 = 47 g /mol
if we match any element from the periodic table , so can find that the titanium has the molecular weight roughly equal to 47.
So The compound is TiCl4 whose molecular weight is 140 g/mol.

1.What is the most common isotope for element X
2.Calculate the average atomic mass or element X
Answers
Answer:
1. Isotope 2 occurs most commonly
2. 39.02amu
Explanation:
1. Isotope 2 has a relative abundance of 78.68% i.e. 78.68 out of 100, hence, it is the isotope that occurs most commonly.
2. Isotope 1 = 9.67%, mass no: 38
Isotope 2 = 78.68%, mass no: 39
Isotope 3 = 11.34%, mass no: 40
Isotope 4 = 0.31%, mass no: 41
To find the average atomic mass of element X, we multiply each isotopes' relative abundance by its mass no and find the sum as follows:
We convert each percentage to decimal abundance:
Isotope 1 = 9.67% = 0.0967
Isotope 2 = 78.68% = 0.7868
Isotope 3 = 11.34% = 0.1134
Isotope 4 = 0.31% = 0.0031
(0.0967 × 38) + (0.7868 × 39) + (0.1134 × 40) + (0.0031 × 41)
3.6746 + 30.6852 + 4.536 + 0.1271
Average atomic mass = 39.02amu

the total volume of hydrogen gas needed to fill the hindenburg was l at atm and . given that for is , how much heat was evolved when the hindenburg exploded, assuming all of the hydrogen reacted to form water?
Answers
2.4453 × 10⁹ KJ energy was evolved when the total volume of hydrogen gas needed to fill the hindenburg was 2.09 × 10⁸ l at 1.00 atm and 25.1°
According to the given data,
Volume of the hydrogen gas = 2.09 × 10⁸ L
Pressure of the gas = P = 1 atm
Temperature of the gas =T = 25.1 °C =298.1 K
We know that, for an ideal gas equation
PV=nRT
1 atm ×2.09 × 10⁸ L = n × 0.0820 atmL/molK × 298.1 K
⇒n = 1 atm ×2.09 × 10⁸ L/ 0.0820 atmL/molK × 298.1 K
⇒n = 0.0855 ×10⁸ mol
ΔH for hydrogen gas is =-286 kJ/mol
For 0.0855 ×10⁸ mol energy evolved when hydrogen gas is burned =
0.0855 ×10⁸ mol × (-286 KJ/mol) = -2.4453 × 10⁹ KJ
Therefore, 2.4453 × 10⁹ KJ energy was evolved when it was burned.

As a result of the tax, a. consumer surplus decreases from $200 to $80. b. the market experiences a deadweight loss of $80. c. producer surplus decreases from $200 to $145. d. total surplus increases from $180 to $200.
Answers
Based on the given information, we can analyze the effects of the tax on consumer surplus, producer surplus, deadweight loss, and total surplus:
Consumer surplus decreases from $200 to $80: This statement suggests that the tax has reduced the benefit received by consumers in the market. Consumer surplus represents the difference between what consumers are willing to pay for a good or service and what they actually pay. If consumer surplus decreases from $200 to $80, it implies that the tax has increased the price consumers have to pay, thereby reducing their surplus .The statement suggests that the deadweight loss in the market due to the tax is $80.

Which is not a chemical mutagen?.
Answers
Ethyl alcohol is not a chemical mutagen.
Chemical mutagens are common methods for mutagenesis in a number of organisms, and in most genetic systems, they are the main way to introduce mutations into phenotype-based screens. Alkylating chemicals that cause point mutations in DNA, such as ethyl-methane sulfonate and N-methyl-N-nitrosourea, are the most often utilized chemical mutagens. Only option C is a physical mutagen while others are chemical mutagens provided in the question.
Alcohol causes cancer, birth defects, and mutations in humans. The first metabolite of ethanol, acetaldehyde, is mutagenic. The discovery that acetaldehyde causes sister-chromatid exchanges, chromosomal aberrations, and cross-links between DNA strands supports this.

Engineering Question 15 of 30 Which of the following devices is used for atomizing and vaporizing the fuel before mixing it with air in varying proportions? O Spark plug O Carburetor O Flywheel Govern
Answers
The primary goal of the carburetor is to atomize and vaporize the fuel before mixing it with air in varying proportions, making it the device that is used for atomizing and vaporizing the fuel before mixing it with air in varying proportions.
The device that is used for atomizing and vaporizing the fuel before mixing it with air in varying proportions is Carburetor. A carburetor is a device that blends air and fuel for an internal combustion engine. It is often located on the top of an engine on a direct engine-to-carburetor link, and it controls how much air and fuel are mixed.The carburetor must also supply the engine with a spark plug to ignite the fuel/air mixture in each cylinder.
The carburetor must provide a fuel/air mixture that is consistent with the engine's changing demands, which vary with engine speed, load, and temperature. A carburetor is responsible for enriching the fuel/air mixture when the engine is cold and for leaning the mixture as the engine warms up. As well, it is also responsible for regulating the fuel/air mixture at part-throttle levels, where the engine spends most of its time when driving.
When an engine is running at full throttle, it is operating at wide-open throttle (WOT), and the carburetor provides the richest fuel/air mixture possible.The carburetor, like most engine systems, is a complex and sensitive device that must be correctly tuned to perform properly. The primary goal of the carburetor is to atomize and vaporize the fuel before mixing it with air in varying proportions, making it the device that is used for atomizing and vaporizing the fuel before mixing it with air in varying proportions.
