The effects of long-term exposure to mustard gas causes mortality and chronic respiratory disease.
Exposure to mustard gas in the long term can result in mortality from influenza, pneumonia as well as chronic breathing disease. Exposure for long term leads to respiratory complications and septic shock. Extensive breathing in the environment of mustard gas can cause chronic respiratory disease, respiratory infections or death.
Extensive eye exposure to this gas can cause permanent blindness. Exposure to mustard gas may also increase the chances of lung and respiratory cancer so we can conclude that mustard gas is lethal and can cause a number of diseases in a person who is exposed to it.

Answer:
The most common injury caused by working with machinery are cuts and burns.
Explanation:
Cuts and burns are the most common injury caused by working with machines unsafely.
What is injury?Any physiological harm to living tissue brought on by acute physical stress is referred to as an injury. An injury can be brought on by a blunt trauma, a piercing trauma, burning, exposure to chemicals, asphyxiation, or overexertion, and it can also happen accidentally. Any area of the body can become injured, and each injury has a unique set of symptoms.
Major injuries are normally treated by a medical practitioner, and the type of treatment depends considerably on the injury. The most frequent reason for accidental human injury or injury-related death is traffic crashes. Chronic conditions are different from injuries. Cuts and burns are the most common injury caused by working with machines unsafely.
Therefore, Cuts and burns are the most common injury caused by working with machines unsafely.

Where does the energy of a hurricane come from? (1 point)
O the Sun
O strong winds
O Earth's spin
O Earth's moon
Answer:
strong winds come from the energy of a hurricane
The energy of a hurricane come from strong wind. The Taino Native American term hurricane, which translates to "bad spirit of the wind," is where the word hurricane originates.
What is hurricane ?A tropical storm that has sustained winds of 74 mph or greater is referred regarded as a hurricane. A storm's eye typically measures 20 to 30 miles in width and can reach distances of 400 miles. Storms can be dangerous because of their torrential downpours, strong gusts, and storm surges.
When warm, humid air begins to rise over water, hurricanes emerge. Cooler air replaces the rising air. Large clouds and thunderstorms continue to grow as a result of this process. Thanks to the earth's Coriolis Effect, these thunderstorms are still expanding and starting to rotate.
Thus, option B is correct.

a student is given a mixture of sand and salt. describe a method the student could use to separate the mixture.
There is a golden role of solubility, polar solute dissolve in polar solvent and non polar solute dissolve in non polar solvent. Therefore, Salt and sand can be separated by dissolving the salt in water, filtering the mixture, and then evaporating the water to recover the salt.
What is solution?Solutions are a homogeneous mixture of two or more substances. A solution is a homogeneous mixture of solvent and solute molecules. Solvent is a substance that is in large amount in solution.
Solute is the substance which is in small amount in a solution. Salt and sand can be separated by dissolving the salt in water, filtering the mixture, and then evaporating the water to recover the salt.

An atom's Lewis dot structure has three dots. Which of the following elements could it be, and why? (4 points)
Group of answer choices
Aluminum, because it is in group 13 and has three valence electrons.
Lithium, because it is a group 1 element with three total electrons.
Magnesium, because it is in period 3 and has three valence electrons.
Potassium, because it is an alkali metal and has three inner shell electrons.
Answer : The correct option is, Magnesium because it is a group 2 element with two valence electrons.
Explanation :
Element = Calcium
Atomic number = 20
Electronic configuration of Ca =
Number of valence electrons in Ca = 2
The number of inner shell electrons in Ca = 18
This option is wrong because lewis-dot structure shows only valence electrons not inner shell electrons.
Element = Carbon
Atomic number = 6
Electronic configuration of C =
Number of valence electrons in C = 4
This option is wrong because only outermost p-sublevel electrons are not showing in lewis-dot structure.
Element = Lithium
Atomic number = 3
Electronic configuration of Li =
Number of valence electrons in Li = 1
This option is wrong because it has only 1 electron in outermost shell.
Element = Magnesium
Atomic number = 12
Electronic configuration of Ma =
Number of valence electrons in Ma = 3
This option is correct.
Lewis-dot structure : It is defined as the structure in which valence electrons of the atom is shown as dots.
ANOTHER EXPLANATION:
Answer: C. Magnesium, because it is a group 2 element with two valence electrons.
An atom's Lewis dot structure has two dots. Which of the following elements could it be, and why?
A. Calcium, because it is an alkaline earth metal with two inner shell electrons.
B. Carbon, because it has two electrons in its outermost p sublevel.
C. Lithium, because it is a group 1 element with two bonding electrons.
D. Magnesium, because it is a group 2 element with two valence electrons.
Explanation:
If you were to look at the periodic table magnesium would be in group 2. Since magnesium is in group 2 therefore it will have two valence electrons. Calcium is another possible answer because it is also in group two, but for this quiz it is incorrect. Lithium is incorrect because it is in group 1 and therefore it would only have 1 valence electron. Carbon is also incorrect because it is in group 14 so it would have 4 valence electrons. Hope this helps and makes sense.
Good Luck!!

SnO is a different compound than SnO2. What is the difference regarding the cation?
Answer:
Sn has a different charge in each of the compounds.
+2, +4 charges, respectively.
Explanation:
SnO has subscripts of 1, which means it takes only one of each element to make the compound.
We know that oxygen's charge is -2 from the periodic table.
In order for the compound to be neutrally charged,
Sn + O = 0
Sn - 2 = 0.
So, Sn has a +2 charge.
Likewise with the second compound, we know O has a -2 charge.
Sn + 2*(-2) = 0
Sn - 4 = 0
Sn = +4
+2 and +4 are different charges on the Sn cation.
