56.8g of aluminum chloride will be produced if the reaction begins with 135.0 g Al and 75.0 g chlorine gas.
What is mass?A body's mass is an inherent quality. Prior to the discovery of a atom or particle physics, it was widely considered to be tied to the amount of matter inside a physical body. It was discovered that, despite having the very same quantity of matter in theory, different atoms and elementary particles have varied masses.
There are various conceptions of mass in contemporary physics that are theoretically different but physically equivalent. The resistance of the body to acceleration in the presence of a net force can be measured experimentally as mass. The gravitational pull an object has on other bodies is also influenced by its mass.
2 Al + 3 Cl[tex]_2[/tex] → 2 Al C l[tex]_3[/tex]
mole of Al = 135.0/ 26=5.19mol
mole of Cl[tex]_2[/tex] = 75.0/ 35 =2.14 mol
mass of aluminum chloride = 56.8g
Limiting reagent = Al
excess reactant = Cl[tex]_2[/tex]
Therefore, 56.8g of aluminum chloride will be produced if the reaction begins with 135.0 g Al and 75.0 g chlorine gas.

how heart attacks and Strokes caused by cholesterol
With high cholesterol, you can develop fatty deposits in your blood vessels. Eventually, these deposits grow, making it difficult for enough blood to flow through your arteries. Sometimes, those deposits can break suddenly and form a clot that causes a heart attack or stroke.
Answer:
Cholesterol is a waxy substance found in your blood. Your body needs cholesterol to build healthy cells, but high levels of cholesterol can increase your risk of heart disease.
With high cholesterol, you can develop fatty deposits in your blood vessels. Eventually, these deposits grow, making it difficult for enough blood to flow through your arteries. Sometimes, those deposits can break suddenly and form a clot that causes a heart attack or stroke.
Explanation:
High cholesterol can cause a dangerous accumulation of cholesterol and other deposits on the walls of your arteries (atherosclerosis). These deposits (plaques) can reduce blood flow through your arteries, which can cause complications, such as:
Chest pain. If the arteries that supply your heart with blood (coronary arteries) are affected, you might have chest pain (angina) and other symptoms of coronary artery disease.
Heart attack. If plaques tear or rupture, a blood clot can form at the plaque-rupture site — blocking the flow of blood or breaking free and plugging an artery downstream. If blood flow to part of your heart stops, you'll have a heart attack.
Stroke. Similar to a heart attack, a stroke occurs when a blood clot blocks blood flow to part of your brain.

Why the bond in water molecule os polar covalent bond, while than in chlorine molecule is pure covalent bond? Give reason?
Explanation:
The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles - a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side). We say that the water molecule is electrically polar.
If combining cation A with a +3 charge and anion X with a -3 charge, how would we write the compound?
O AX
O A3X3
O 3AX
Answer: it’s not A3X3
Explanation:
1. AX
For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion.If a cation A carries +3 charge and an anion X carries -3 charge, the compound so formed is AX. Since the charges gets cancelled out.For example: consider aluminum phosphate, aluminum carries +3 charge and phosphate carries -3 charge, the molecular formula for the compound will be AlPO₄.Learn more:

Which of these compounds has the largest percentage by mass of nitrogen? NO N2O NO2 N2O3
The largest mass percentage of nitrogen in NO. Therefore, option (A) is correct.
What is the mass percentage?The percentage by mass of an element in a chemical compound can be described as the number of parts by mass of the element contained in 100 parts by mass of a chemical compound.
The mass percentage of an element can be determined in two steps:
First, calculate the molar mass of the compound and then the percentage of each element by dividing the total mass of the element present in the compound by the molecular mass of the compound multiplied by 100.
Given, the molecular formula of the compound is NO.
The molecular mass of the NO = 30 g/mol
The mass percentage of the Nitrogen = (14/30) × 100 = 46.67 %
the molecular formula of the compound is NO₂.
The molecular mass of the NO = 46 g/mol
The mass percentage of the Nitrogen = (14/46) × 100 = 30.4 %
the molecular formula of the compound is N₂O.
The molecular mass of the NO = 44 g/mol
The mass percentage of the Nitrogen = (14/44) × 100 = 31.81 %
the molecular formula of the compound is N₂O₃.
The molecular mass of the NO = 76 g/mol
The mass percentage of the Nitrogen = (28/76) × 100 = 36.84 %

A hockey puck is hit with a large force. The puck moves at a high speed as it slides over the ice.
What happens according to Newton’s first law of motion?
A) The puck does not lose any speed because ice is a very slippery surface.
B) The puck gradually slows down because mass makes objects slow down.
C) The puck gradually slows down because friction would be acting on it.
D) The puck does not lose any speed because once an object starts moving, the force of friction would no longer apply to it.
Answer:
C) The puck gradually slows down because friction would be acting on it.
Explanation:
It would be C because the puck would be scraping the ice and when it's scraping it slowly losses its speed because the ground is pushing it lightly

How many milliliters of 0.25M H2SO4 can be prepared from 57 mL of a 3.0M solution of H2SO4?
Answer:
Why ? Because 1 molecule of H2SO4 gives 2 H+ ions per molecule while only one H+ ion is required to neutralize 1 molecule of KOH. So, 1 molecule of H2SO4 can neutralize 2 molecules of KOH. Hence, we would require 525 ml of 0.03 M H2SO4 to neutralize 525 ml of 0.06 M KOH. How will we prepare 525 ml of 0.03 M H2SO4 ?
Explanation:
Now, we have 0.025 M H2SO4 and we do not know how much volume we have.
We will use the standard N1 X V1 = N2 X V2 for this calculation.
N1=0.025 M; V1=unknown; N2=0.03 M and V2=525 ml.
So V1= (0.03 X 525)/(0.025) = 630 ml.
According to the molar concentration, 684 ml of 0.25 M H₂SO₄ can be prepared from 57 mL of a 3.0 M solution of H₂SO₄.
What is molar concentration?Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to solute concentration in a solution . Most commonly used unit for molar concentration is moles/liter.
The molar concentration depends on change in volume of the solution which is mainly due to thermal expansion. Molar concentration is calculated by the formula, molar concentration=mass/ molar mass ×1/volume of solution in liters.
In terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.In case of 2 solutions,it is calculated as, M₁V₁=M₂V₂ substitution gives V₁=3×57/0.25=684 ml.
Thus, 684 ml of 0.25 M H₂SO₄ can be prepared from 57 mL of a 3.0 M solution of H₂SO₄.

Example 1 How much water (in grams) is produced when 65.2 grams of Calcium carbonate react with phosphoric acid to form calcium phosphate, water, and carbon dioxide?
Answer:
11.75 g H2O
Explanation:
3CaCO3 + 2H3PO4 --> Ca3(PO4)2 + 3H2O + 3CO2
MM H2O = 18.02 g/mol
MM CaCO3 = 100 g/mol
? g H2O = mass CaCO3 x (1 mol CaCO3/MM CaCO3) x (3 moles H2O/3 moles CaCO3) x (MM H2O / 1 mol H2O) = (65.2/100) x 18.02 = 11.75 g H2O

A seedling is planted in soil that does not have any clay. What will most likely happen to the plant?
Answer:
Explanation:
Under good conditions the seedling can thrive in soil that does not have any clay as long as it gets the proper nutrients and right amount of sunlight/water that it needs. Clay in soil can provide the nutrients necessary for seedlings to thrive but can also cause many negatives. One such con of using clay is that it does not absorbe water very well, this ultimately causes the soil to become waterlogged and drowns the plants as no oxygen can pass through. This would ultimately kill the plants.

4 Hydrogen has three naturally occurring isotopes. H.1, H-2, and H-3 The atomie mass of Hydrogen is 1.097 Which isotope is most abundant in nature? Explain
Answer:
The number following the name of the element is the number of subatomic particles inside the nucleus of the atom. This means that it is the mass number of the isotope. The average atomic mass of the element is the sum of the products of the percentage abundance and mass number of the naturally occurring isotopes.
Since, the average atomic mass of the hydrogen is nearest to 1 then, the most abundant isotope should be hydrogen-1.
