# What volume in milliliters of H20 you need during preparation of 100 milliliters of 14.00 M H2SO4 solution starting with bottle of 17.5 M H2SO4? (Round your answer to closest integer)

20 mL

Explanation:

We can determine the required volume of the concentrated (17.5 M) H₂SO₄ solution by using the C₁V₁=C₂V₂ formula:

• 17.5 M * V₁ = 14.00  M* 100 mL
• V₁ = 80 mL

As out of the 100 mL of the final solution, 80 mL are from the concentrated H₂SO₄ solution, the remaining 20 mL are of water (H₂O).

Consider the reaction of aqueous potassium sulfate with aqueous g silver nitrate based on the solubility rule predict the product likely to be precipitate write a balanced molecular equation describing the reaction.

K₂SO₄(aq)  + 2AgNO₃ (aq) →  2KNO₃(aq) + Ag₂SO₄ (s) ↓

2Ag⁺ (aq) + SO₄⁻²(aq) ⇄ Ag₂SO₄ (s) ↓

Explanation:

Our reactants are: K₂SO₄ and AgNO₃

By the solubility rules, we know that sulfates are insoluble when they react to Ag⁺, Pb²⁺, Ca²⁺, Ba²⁺, Sr²⁺, Hg⁺

We also determine, that salts from nitrate are all soluble.

The reaction is:

K₂SO₄(aq)  + 2AgNO₃ (aq) →  2KNO₃(aq) + Ag₂SO₄ (s) ↓

2Ag⁺ (aq) + SO₄⁻²(aq) ⇄ Ag₂SO₄ (s) ↓

How many joules are released when one atom of americium 241, the isotope used in ionization-type smoke detectors, undergoes apha emission?

When Americium (Am-241) undergoes alpha decay(He-4) it forms neptunium (Np-237) based on the following pathway:

²⁴¹Am₉₅ → ²³⁷Np₉₃ + ⁴He₂

The energy released in given as:

ΔE = Δmc²

where Δm = mass of products - mass of reactants

= [m(Np-237) + m(He-4)] - [m(Am-241)]

= 237.0482+4.0015-241.0568 = -0.0073 g/mol = -7.3 * 10⁻⁶ kg/mol

ΔE = -7.3*10⁻⁶ kg/mol * (3*10⁸ m/s)² = -5.84*10¹¹ J/mol

You wish to prepare 100 mL of a 0.100 M solution by dilution of a 1.00 M solution. Which of the following pieces of glassware will you use? A. 100 mL graduated cylinder
B. 100 mL volumetric flask
C. 10 mL volumetric pipet
D. 25 mL volumetric pipet
E. 10 mL graduated pipet
F. 25 mL graduated pipet

C

Explanation:

The volumetric pipet is designed for a specific volume of solution. In this case, a 10 mL of volumetric pipet is required to take exactly 10 mL of the solution 1.00 M and add into a volumetric flask of 100 mL. Then water or solvent(s) can be added to reach the ring of the volumetric flask. This volumetric flask is also a laboratory equipment for precis dilutions beside the volumetric pipet

What are some other things that have been engineered to help people deal with the effects of gravity?​

Answer: weight helps gravity

Explanation

for example, when you outside with the wind blowing, your weight dont let you get carried away.

Technologies helping humans cope with gravity include methods to simulate weightlessness for training and entertainment, and prospective technologies suggested by general relativity theories like the gravity-based time machine. Studies on the gravity response in plants can also help sustain long-term space missions.

### Explanation:

There are many technologies and methods designed to help humans cope with the effects of gravity. For example, astronauts on the International Space Station (ISS) experience gravity but appear weightless because they are in constant free fall around the Earth. This is akin to the principle of equivalence, which states that falling around the Earth creates the same effects as being far off in space, away from all gravitational influences.

Training facilities, like NASA's Vomit Comet, provide an environment for astronauts to experience a state of near-weightlessness or free fall, preparing them for their missions in space. Moreover, innovations such as underwater filming, wire stunts, and computer graphics can also mimic the appearance of weightlessness, as seen in movies such as Gravity and The Martian.

Also, findings related to gravity and time machines in general relativity suggest that it might be possible, in theory, to move through time using gravity. Meanwhile, studies on how plants respond to gravity might contribute to long-duration space missions by regenerating the atmosphere, purifying water, and producing food.
