Express the answer in scientific notation and with the correct number of significant figures: (6.32 x 10-4) ÷ 12.64

Answers

Answer : $5.0 X 10^(-5)$

Explanation : We need to simply calculate the division for finding the correct answer and which can be expressed in scientific notation.

$(6.32 X 10^(-4) )/(12.64)$

The answer on solving will be $5.0 X 10^(-5)$ .

Simple division method was used to find out the answer.

A spherical ball of lead has a diameter of 2.5 cm . What is the mass of the sphere if lead has a density of 11.34 g/cm3? (The volume of a sphere is (43)πr3 where r is the radius.)

Answers

Answer : The mass of sphere is 92.727 grams.

Explanation :

To calculate the volume of sphere, we use the formula:

$V=(4)/(3)\pi r^3$ .....(1)

where,

r = radius of sphere

Given :

Diameter of sphere = 2.5 cm

Radius of sphere = $(Diameter)/(2)=(2.5cm)/(2)=1.25cm$

Now put all the given values in the above formula (1), we get:

$V=(4)/(3)* 3.14* (1.25cm)^3$

$V=8.177cm^3$

To calculate mass of a substance, we use the equation:

$Density=(Mass)/(Volume)$ .....(2)

Putting values in above equation (2), we get:

$11.34g/cm^3=(Mass)/(8.177cm^3)$

$Mass=92.727g$

Hence, the mass of sphere is 92.727 grams.

mass = volume x density

volume = πr²
since Diameter = 2.5 cm
then radius = 1.25cm

∴ volume = π x (1.25cm)³
≈ 6.1359 cm³

Thus mass = 6.1359 cm³ x 11.34 g / cm³
= 69.58 g

Mindy and her lab partner conducted flame tests of several metallic salt solutions. They dipped a wire loop into each salt solution, and one by one, heated the sample in the Bunsen burner flame. Based on their results, which element produced a colored light with the lowest energy?A) barium
B) calcium
C) copper
D) potassium

Answers

Flame tests of metals produce various colors. The colors produced by each of the choices are:

A. barium - pale green
B. calcium - yellow red
c. copper - green blue
d. potassium - lilac

Using the visible light spectrum, it can be determined that the metal with the lowest energy is B. calcium. This is because the color yellow-red is near the end of the spectrum with the longest wavelength. Since wavelength is inversely proportional to energy, calcium has the lowest energy.

Answer:

Explanation:

The color of the emitted light depends on the energy. According to the arrangement of the electromagnetic spectrum, the color red has the lowest energy, the lowest frequency, and the largest wavelength

What type of radiation is emitted when polonium-212 forms lead-208?a. an alpha particle
b. a beta particle
c. gamma radiation
d. all of the above

Answers

Answer: The radiation that is emitted from the above process is alpha particle.

Explanation:

Alpha decay is defined as the process in which alpha particle is emitted. In this process, a heavier nuclei decays into a lighter nuclei. The alpha particle released carries a charge of +2 units. The released alpha particle is also known as helium nucleus.

$_Z^A\textrm{X}\rightarrow _(Z-2)^(A-4)\textrm{Y}+_2^4\alpha$

Beta decay is defined as the process in which beta particle is emitted. In this process, a neutron gets converted to a proton and an electron. The released beta particle is also known as electron.

$_Z^A\textrm{X}\rightarrow _(Z+1)^A\textrm{Y}+_(-1)^0\beta$

Gamma decay is defined as the process in which an unstable nuclei gives off excess energy by a spontaneous electromagnetic process and thus releases $\gamma -radiations$ .

These radiations does not carry any charge and are electrically neutral.

$_Z^A\textrm{X}^*\rightarrow _Z^A\textrm{X}+_0^0\gamma$

The chemical equation for the decay of polonium-212 isotope follows:

$_(84)^(212)\textrm{Po}\rightarrow _(82)^(208)\textrm{Pb}+_2^4\alpha$

Hence, the radiation that is emitted from the above process is alpha particle.

A. An alpha particle.
