Answer:
The disadvantages of each of the given model of electron configuration have been mentioned below:
1). Dot Structures - They take up excess space as they do not display the electron distribution in orbitals.
2). Arrow and line diagrams make the counting of electrons and take up too much space.
3). Written Configurations do not display the electron distribution in orbitals and help in lose counting of electrons easily.
Answer:
The essence including its particular subject is outlined in the following portion mostly on clarification.
Explanation:
- The energy throughout the campfire comes from either the wood's latent chemical energy until it has been burned to steam up and launch up across the campfire. The electricity generation for something like a campfire seems to be in the context including its potential chemical energy which is contained throughout the firewood used only to inflame the situation.
- The energy output seems to be in the different types of heat energy radiating across the campfire, laser light generated off by the blaze, and perhaps a little number of electrical waves, registered throughout the firewood cracking whilst they combust throughout the blaze.
and,
chemical energy ⇒ heat energy + light energy + sound energy
Answer:inner Diameter =9.19cm
Explanation:
Density is calculated as Mass/ Volume
therefore
Volume= Mass/ Density = 1360g/ 0.953g/ml=1,427 ml
1ml = 1cm³
1,427ml = 1,427cm³
Also We know that Volume of a cylinder = πr²h or πr²l
1,427cm³ = 3.142 x r² x 21.5 cm
r² = 1,427cm³/ (3.142 x 21.5cm)
r² =21.124cm²
= r²
r= 4.596cm
Diameter= 2 x radius
=2 x 4.596
=9.19cm
Since the mass of a single popcorn kernel is not given, lets us assume that it is 1 gram
Now:
1 mole of popcorn kernels contain
kernels
Since:
1 kernel weighs 1 gram
Then,
kernels would weigh
grams
Answer:
2Ag (s) + 2HNO3 (aq) → 2AgNO3 (aq) + H2(g)
Explanation:
Usually, metals displace hydrogen from dilute acids to form the corresponding salt of the metal and hydrogen. This in turn depends on the position of the metal in the electrochemical series. Metals below hydrogen in the electrochemical series cannot spontaneously displace it from dilute acids. Silver is below hydrogen in the electrochemical series, hence it cannot spontaneously displace hydrogen from dilute nitric acid as shown in the answer.
