How does oxygen obey the octet rule
Answer:
oxygen obey the octet rule when reacting to form compounds by adding 2 electrons.
Explanation:
Answer:
See below.
Explanation:
An oxygen atom, in free state has 8 electrons, 2 in the first shell, and 6 in the second. It can only achieve stability if the valency of the valence shell is 0. In order for this, it combines with another atom with the same valency, such as magnesium or another oxygen atom to obey the octet rule. Hope it helps.

Copper reacts with sulfur to form copper (i) sulfide, according to the balanced equation below. 2cu s → cu2s given that there are 40.2 g cu and 14.1 g s, complete the steps below to determine the limiting and excess reactants in the last question. how many moles are in 40.2 g cu? mol cu how many moles are in 14.1 g s? mol s
The limiting reactant would be Cu and the excess reactant would be S.
Stoichiometric reactantFrom the equation:
2Cu + S → Cu2S
Mole ratio of Cu to S = 2:1
Mole of 40.2 g Cu = 40.2/63.55
= 0.63 moles
Mole of 14.1 g of S = 14.1/32.07
= 0.44 moles
Equivalent mole of Cu = 0.44 x 2 = 0.88 moles
Thus, Cu is limiting while S is in excess.

Explanation:
The deciduous forest supports a diverse ecology. A warm growing season with abundant moisture encourages plants to grow, and the ground is covered with small plants, flowers, ferns, and grasses. In spring the trees and shrubs produce new leaves and colorful flowers. In summer the tall trees cast shade on the forest floor, providing ideal growing conditions for shade-tolerant plants. Seeds and berries provide for plant reproduction, and feed small rodents and birds. The leaves that fall in the autumn provide plenty of material for decomposers, soil bacteria, worms, grubs, and fungi. All these plants together are the primary producers. If berries were destroyed and taken out of the food web, which organisms would be directly affected? *
10 points
Captionless Image
The snake, the owl, and the fox would be directly affected by the loss of berries.
The mouse and the frog would be directly affected by the loss of berries.
No organisms in the food web would be directly affected by the loss of berries.
The squirrels, rabbits, and grasshoppers would be directly affected by the loss of berries.
Answer:
The squirrels, rabbits, and grasshoppers would be directly affected by the loss of berries.
Explanation:
Refer to the attached picture below.
The arrows in the diagram represent which way the energy flows. There are only three ways the energy flows directly to an organism. Those are to the grasshopper, the frog, and the rabbit. (in the picture below, these are circled in red.)
Therefore, we can assume that the correct answer would be D. The squirrels, rabbits, and grasshoppers would be directly affected by the loss of berries.

Which of the following statements is true?
A. Magnesium (Mg) is brittle.
B. Iodine (I) is magnetic.
C. Copper (Cu) conducts heat.
D. Iron (Fe) has a low density.
Answer:
I think it's C.copper conducts heat
The elements of the periodic table are arranged in the families and periods based on their properties. Copper (Cu) is a transition metal that can conduct electricity. Thus, option C is correct.
What are transition metals?Transition metals are the metallic elements that are arranged in groups 3 - 12 and periods 4-7. They are also called d-block elements due to the electron present in the d orbit of the atom making them capable of bond formation.
They all show the properties of metals that include shininess, luster, conductivity, etc. The series include copper, iron, cobalt, gold, zinc, chromium, nickel, manganese, molybdenum, etc.
Copper being a transition metal has the property of conducting electricity and is used in wirings as they have loosely bounded electrons in their shell that can carry the electrical charge in a circuit.
Therefore, option C. copper (Cu) can conduct electricity and heat is correct.

Which object will have particles with the highest average kinetic energy?(1 point)
1. an iceberg at 0°C
2. water at 37°C in a glass
3. a drop of water at 90°C
4. water at 40°C in a swimming pool
Answer:
The answer will "a drop of water at 90°C"
Explanation:
Kinetic energy is a measurement of how fast or slow particles move. And temperature = Kinetic energy.
What does this mean?
Well, this means that the higher the temperature, the higher the kinetic energy. The mass of the water doesn't affect the kinetic energy, since the kinetic energy is the measurement of only the movement of the particles. So, we can ignore the masses. Therefore, that means the answer will be the drop of water, as it has the highest temperature.
Average kinetic energy is the average sum of all kinetic energy of all the molecules of gases. A drop of water at 90°C has the greatest average kinetic energy. Therefore option 3 is the correct option.
What is kinetic energy?
It is a energy which is possess by a moving object. It is very difficult to find the correct value of kinetic energy so we find average kinetic energy. Which is very easy to calculate as compared to calculating kinetic energy . Average kinetic energy is directly proportional to temperature. It is not dependent on the type of gases or mass of gases
Mathematically,
K.E=2/3KT
Where,
K= Boltzmann constant
T is the temperature
Water at higher temperature will have higher average kinetic energy. Among given options, a drop of water at 90°C is at higher temperature. Thus a drop of water at 90°C has the highest average kinetic energy among all. Therefore option 3 is the correct option.

The answer is 3.14 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume}\\[/tex]
From the question
mass = 78.51 g
volume = final volume of water - initial volume of water
