Wich tools are appropriate to determine the densety of an irregular-shaped object ?

Answers

Answer:

The most accurate way to determine an object's volume, especially in the case of an irregularly shaped object, is to immerse it in water and measure the amount of water it displaces. A graduated cylinder large enough to hold both the object and enough water to fully immerse it is the best tool for this job.

If the half-life of iodine-131 is 8.0 days, how much of a 100.0 mg sample of it will remain after 32 days? In case you're interested, iodine-131 forms xenon-131 by beta emission/decay. Please enter only a numerical answer and do not write in any units. It is understood that the unit is mg.

Answers

Given :

Half-life of Iodine , [tex]t_{0.5}=8 \ days[/tex] .

Initial concentration , [tex][A_o]=100\ mg[/tex] .

To Find :

The amount of sample remains after 32 days .

Solution :

Rate constant is given by :

[tex]k=\dfrac{0.693}{t_{0.5}}\\\\k=\dfrac{0.693}{8}\ s^{-1}\\\\k=0.086625\ s^{-1}[/tex]

Now , by rate law :

[tex][A]=[A_o]e^{-kt}[/tex]

Putting all given values, we get :

[tex][A]=100\times e^{-(0.086625)\times 32}\\[/tex]

[tex][A]=6.25\ mg[/tex]

Therefore , the remaining sample after 32 days is 6.25 mg .

Hence , this is the required solution .

Explain how electron microscopes work and why some scientists might prefer to use electron microscopes instead of light microscopes.

Answers

Answer:

Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light. Electrons have much a shorter wavelength than visible light, and this allows electron microscopes to produce higher-resolution images than standard light microscopes.

Given that,

A calorimeter made from a can is used to measure the calories in a peanut.

During the experiment, the  measured calories were 35% of the true/accepted value given by references

Suppose, the mass of peanut is 0.4 g and find the

We need to calculate the heat generated per gram of sample in calories

Using formula of heat generated

[tex]q=\dfrac{q_{penut\ calorimeter}}{m_{peanut}}[/tex]

Put the value into the formula

[tex]q=\dfrac{0.35}{0.4}[/tex]

[tex]q=0.87\ g[/tex]

A liquid has a density of 0.70g/ml. Find the mass of the liquid which can be put

into a beaker holding 130mL.

Answers

Answer:

The answer is

91 g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

density of liquid = 0.70 g/mL

volume = 130 mL

The mass is

mass = 0.7 × 130

We have the final answer as

91 g

Question 26 (1 point)
Use the periodic table to determine which statement below is true of the element Bromine (Br).

•Bromine will lose 7 valence electrons to become a negative ion.
•Bromine will lose 7 valence electrons to become a positive ion.
•Bromine will gain 1 valence electron to become a negative ion.
•Bromine will gain 1 valence electron to become a positive ion.

Answers

Answer:

The correct option is;

Bromine will gain 1 valence electron to become a negative ion

Explanation:

Bromine can be found in period 4 in group 17 of the periodic table and is an halogen

The electron configuration of bromine can be presented as follows;

Electronic configuration 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁵

Therefore, an atom of bromine has 2 + 5 or 7 electrons in its outermost shell, which makes it have one less electron to complete a full octet structure and therefore, bromine has a strong affinity for electron to complete its octet structure and it is thus a strong oxidizing agent.

When bromine enters into a chemical reaction and gains the one valence electron it becomes a negatively charged ion.

In coulombs, how much positive charge is there IN a barium nucleus? On a barium ion?

Answers

Answer:

The amount of positive charge in a barium nucleus is approximately 8.972 × 10⁻¹⁸ coulomb

Explanation:

The amount of positive charge there is in a barium nucleus is found as follows;

The atomic number of an element is equal to the number of proton present in the atom

The atomic number of barium = 56 = The number of protons in an atom of barium

The positive charge of a single proton is known as an elementary charge, e, given by the formula, e = F/N[tex]_A[/tex]

Where;

F = Faraday's constant

N[tex]_A[/tex] = The Avogadro's number

Therefore, e = 1.602 176 634 × 10⁻¹⁹ C

Which gives the positive charge, Q, of the protons of a barium nucleus as follows;

Q = Number of protons × e

Q = 1.602176634 × 10⁻¹⁹ × 56 ≈ 8.972 × 10⁻¹⁸ Coulomb  per atom of barium.

The amount of positive charge in a barium nucleus ≈ 8.972 × 10⁻¹⁸ coulomb.
