help me please im in 4th grade and online is frustrating
Answer:
A
Explanation:
The answer is A) because the A container has tightly packed molecules but not as tight as C so that means A is liquid, and C is a solid which makes B a gas
Answer:
The answer would be A
Explanation:
because in the first picture Liquid could be in many shapes like If I put water in my water bottle it would be the same shape as the water bottle.
In the third picture, the solid molecules will always be so close to each other like they will be stick to each other.
In the second picture, It will be separate always, as it cant stick to each other.

Do you think that participation in a Supervised Agriculture Experience (SAE) prepares a student for a career in the AFN industry? Discuss why you agree or why you don’t. Discuss how your particular SAE has prepared you for your future career.
HELPPPP !! For horticulture
Answer:
The SAE curriculum includes practical farming tasks conducted outside the scheduled classroom and laboratory period by students. SAEs offer a method for students in agricultural education to gain real-world work opportunities that they are most interested in in the field of agriculture. Supervised agricultural experience is an essential component of agricultural education, and all Agriculture, Food and Natural Resources (AFNR) courses are a necessary component.

Which is the state of matter shown in this figure ?
Answer:
It looks like a solid because they are densely packed kind of like an ice cube
Explanation:
The state of matter shown in this figure is solid state, because the particles are arranged densely in the form of cube.
What is solid state ?The state of matter known as a solid has a definite form, mass, and volume. Changing the temperature causes extremely little variations in volume to be seen. For instance, sand, wood, copper, ice, etc., cannot be crushed.
One of the three fundamental states of matter, along with liquid and gas. Since atoms' energy drops when they adopt a comparatively organized, three-dimensional structure, solids can emerge from liquids or gases.
Because solids have specific mass, volume, and form, their component particles are arranged compactly. Between molecules, there is little intermolecular space. As a result, there is a strong force between the constituent particles (atoms, molecules, or ions).
Thus, option A is correct.

What is the difference between a compound and a mixture?
Group of answer choices
A compound is just a mixture of elements.
A mixture can be physically separated into its components; a compound cannot be physically separated into its components.
The components of a mixture do not have the same properties individually as they do when mixed.
A compound can be physically separated into its components; a mixture cannot be physically separated into its components.
Answer:
Compound are substances which can be formed by chemically combining two or more elements. Mixtures are substances that are formed by physically mixing two or more substances. Compounds can be of three types, which are: covalent compounds, metallic compounds and ionic compounds.
Answer:
The answer is a mixture can be physically separated into its components; a compound cannot be physically separated into its components.

Repeat this calculation using Slater's rules to estimate the screening constant, S, and calculate Zeff for these two ions. Express your answers using two decimal places. Enter your answers numerically separated by a comma. 50 A 6 A 0 21 ? S. Zeff C, Zeff K+ =
Answer:
Cl^- = 5.75
K^+ = 7.75
Explanation:
Now let us calculate the effective nuclear charge four K^+ and Cl^- from Slater's rule.
Given that Cl^- and K^+ has electronic configuration of; [Ne] 3s2 3p6 (they are isoelectronic species)
We compute S as follows;
For n - 2 level, S= 1
For n - 1 level, S= 0.85
For ns,np level S= 0.35
Note: S= screening or shielding constant
1s2, S=2 ×1 = 2
2s2 2p6, S= 8×0.85 = 6.8
3s2 3p6, S= 7 × 0.35 = 2.45
The electron under study is not considered hence seven out of eight electrons in the shell are considered
Hence
S= 2 + 6.8 + 2.45 = 11.25
Since Cl^- has 17 electrons;
Zeff(Cl^-) = 17 - 11.25 = 5.75
For K^+
Zeff = 19 - 11.25 = 7.75
Which of the following models best demonstrates the law of conservation of mass??
(LOOK AT THE PICTURES)!!
Answer:
i think its D
Explanation:
The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.
Taking into account the law of conservation of mass,
The Law of Conservation of Matter is also called the law of conservation of mass or the Law of Lomonósov-Lavoisier. This law postulates that "The mass is not created or destroyed, only transformed."
This means that the reagents interact with each other and form new products with different physical and chemical properties than those of the reagents. And this is because the atoms of the substances are ordered differently.
But the quantities of the masses involved in a given reaction must be constant throughout it, that is, they will not have changed in their proportions when the reaction ends. Then the mass before the chemical reaction is equal to the mass after the reaction.
The exception to the rule is nuclear reactions, in which it is possible to convert mass into energy and vice versa.
Finally, the correct answer is option A. because the atoms of the substances are ordered differently, this is the reagents interact with each other and form new products.

Name at least three physical properties of the bowling
ball.
Answer:
The physical properties is hardness shape and color, I choose hardness because I have grabbed bowling balls before and they are very hard well there could be different types of bowling balls made of different things but I have never seen one or toughed a bowling ball that is not hard. Another physical property I chose for the bowling ball was shape, The reason I chose shape was because the bowling ball is circle, the actual name for a 3-D circle is sphere. The last physical property for a bowling ball is color because mostly all bowling balls have color for example the one in the picture it is red with a little bit of pink, there is many different bowling balls that have different color different hardness but NOT different shape. That is the physical properties of a bowling ball.

Given the standard heats of reaction
Reaction ∆H 0
M(s) + 2 X2(g) → MX4(g) −98.7 kJ/mol
X2(g) → 2 X(g) +327.3 kJ/mol
M(g) → M(s) −20.1 kJ/mol
calculate the average bond energy for a single
M-X bond.
Answer in units of kJ/mol.
Answer:
Explanation:
M(s) → M (g ) + 20.1 kJ --- ( 1 )
X₂ ( g ) → 2X (g ) + 327.3 kJ ---- ( 2 )
M( s) + 2 X₂(g) → M X₄ (g ) - 98.7 kJ ----- ( 3 )
( 3 ) - 2 x ( 2 ) - ( 1 )
M( s) + 2 X₂(g) - 2 X₂ ( g ) - M(s) → M X₄ (g ) - 98.7 kJ - 2 [ 2X (g ) + 327.3 kJ ] - M (g ) - 20.1 kJ
0 = M X₄ (g ) - 4 X (g ) - M (g ) - 773.4 kJ
4 X (g ) + M (g ) = M X₄ (g ) - 773.4kJ
heat of formation of M X₄ (g ) is - 773.4 kJ
Bond energy of one M - X bond = 773.4 / 4 = 193.4 kJ / mole
A) Devices that transfer kinetic energy have what for their source of power?
B) Why is burning kerosene for energy not the best solution?
C) Explain why there is not one right why of obtaining energy when it is not available
Answer:
A) Devices that transfer kinetic energy have a source of power that is in motion
Kinetic energy is the energy in motion, as such, a device that transfers kinetic energy transfers the energy the power source has into other energy forms
B) Kerosene does not easily cold start like diesel which can burn after compression
C) The first law of thermodynamics states that energy is conserved and it can neither be created nor destroyed, but can be changed from one form to another.
Therefore, when energy is not available in a given location or body, it cannot be obtained from that body or location
