what is the mass in grams of 1.204x10^24 molecules of hydrogen gas (H2) ?

Answers

Answer:

4.03 g

Explanation:

The mass in grams of the hydrogen gas is 4.0 g

Stoichiometry

From the question,

We are to determine the mass in grams of the hydrogen gas.

First, we will determine the number of moles of hydrogen gas present.

Using the formula,

[tex]Number\ of\ moles =\frac{Number\ of \ molecules}{Avogadro's\ constant}[/tex]

From the given information,

Number of hydrogen molecules = 1.204 × 10²⁴ molecules

Thus,

Number of moles of hydrogen gas present = [tex]\frac{1.204 \times 10^{24} }{6.02 \times 10^{23} }[/tex]

Number of moles of hydrogen gas present = 2 moles

Now, for the mass of the hydrogen gas

Using the formula,

Mass = Number of moles × Molar mass

Molar mass of hydrogen gas = 2.016 g/mol

Then,

Mass of the hydrogen gas = 2 × 2.016

Mass of the hydrogen gas = 4.032 g

Mass of the hydrogen gas ≅ 4.0 g

Hence, the mass in grams of the hydrogen gas is 4.0 g

2Mg + O2 → 2MgO

Explanation:

This question has to do with the balancing of chemical reaction equations. The general rule for balancing chemical reaction equation is that the number of atoms of each element on the left hand side of the reaction equation must be equal to the number of atoms of the same element on the right hand side of the reaction equation.

This principle was followed in balancing each reaction equation above. For instance, in the burning of magnesium, there are two atoms of both magnesium and oxygen on either side of the reaction equation.

how heart attacks and Strokes caused by cholesterol​

Answers

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.

P5b- How many moles of Argon (Ar) are consumed in a reaction that consumes 5 moles of F2 (fluorine)?


I need the answers for the p5 part please help

Answers

Answer:

5a. 13.5 moles of F₂

5b. 3.33 moles of Ar.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

3F₂ + 2Ar —> 2ArF₃

From the balanced equation above,

3 moles of F₂ reacted with 2 moles of Ar to produce 2 moles of ArF₃.

5a. Determination of the number of mole of fluorine, F₂, needed to produce 9 moles of ArF₃.

From the balanced equation above,

3 moles of F₂ reacted to produce 2 moles of ArF₃.

Therefore, Xmol of F₂ will react to produce 9 moles of ArF₃ i.e

Xmol of F₂ = (3 × 9)/2

Xmol of F₂ = 13.5 moles

Thus, 13.5 moles of F₂ is needed.

5b. Determination of the number of mole of Ar needed to react with 5 moles F₂.

From the balanced equation above,

3 moles of F₂ reacted with 2 moles of Ar.

Therefore, 5 moles of F₂ will react with = (5 × 2)/3 = 3.33 moles of Ar.

Thus, 3.33 moles of Ar was consumed.
