Answer:
product is the item offered for sale. A product can be a service or an item. It can be physical or in virtual or cyber form. Every product is made at a cost and each is sold at a price. The price that can be charged depends on the market, the quality, the marketing and the segment that is targeted.
the various geologic settings in which rocks can melt, metamorphose, or become sediment are ultimately generated by
Geological settings whereby there is melting of rock as well as formation of sediments can be attributed to Plate tectonics .
Plate tectonics can be regarded as theory which explained the Earth's outer shell and how its been divided into solid rocks as well as slabs and its often referred to as Plate.
Plate tectonics explained that there is a large-scale motion plates which Earth's lithosphere is made up.Tectonic processes started about 3.3 and 3.5 billion years ago. Through the generation of Tectonic plate, there are melting of rocks as well as generation of sedimentsThe types of boundaries that exist between those tectonic plates can be categorized into 4, base on the the movement of the plates, and these are;divergent boundariesconvergent boundariestransform fault boundaries plate boundary zonesTherefore, plate tectonic gives explanation about Earth's outer shell.

how to tell how many valence electrons an atom has?
Answer: Count only the electrons in the highest shell s and p orbitals when determining valence.
Explanation: I'm glad you asked this question. It is often not well explained. The term valence electrons is assigned to only the electrons in an element's highest energy level. These reside only in the s and p orbitals, and not the d or f, as I'll explain later. The s orbital can hold 2 electrons and the p can hold 6. Potassium, K, has an s orbital in its highest energy shell, 4. It contains only 1 electron, so it has a valency of 1.
Calcium, Ca, has 2 in its highest energy level: 4s^2, so it has a valency of 2. Moving to the right, the element scandium, Sc, add another electron, but it goes into the 3d orbital. 3d is in the 3rd energy shell, so it is not counted as a valence electron. Only after we move further right, to gallium, Ga, do we start adding electrons to the 4th energy level again - the 4p orbitals can accept up to 6 electrons. Ga has 3 valence electrons - 2 in the 4s and 1 in the 4p. Oxygen has 2 in the 2s and 4 in the 4p orbitals, for a total of 6. It is close to having a comple outer shell (2 in the 2s and 6 in the 2p). Just 2 more electrons would fill both the 2s and 2p orbitals for a total of 8 valence electrons, a stable configuration (the same configuration as thje stable gas Neon).

Answer:
Water cooled down and contracted.
Explanation:
When water contracts, its volume decreases. When the volume of the water in the bottle system decreases, the water is pulled farther down the clear pipe.

Determine whether each of the reactions given below would be spontaneous or not. Please justify your answer in each case.
A. Fe2+ (aq) + Al (s) → Al3+(aq) + Fe (s)
B. Pb2+ (aq) + Sn (s) → Sn2+ (aq) + Pb (s)
C. Mg2+ (aq) + Ag (s) → Ag+ (aq) + Mg (s)
A spontaneous reaction is one in which the change in free energy is negative and the standard cell potential is positive.
For a redox reaction to be spontaneous, the electrode potential of the cell must be positive and this depends on the relative electrode potentials of the species involved in the reaction. A metal can not displace a metal above it in the electrochemical series from solution.
Based on this;
Fe2+ (aq) + Al (s) → Al3+(aq) + Fe (s) is spontaneous because iron is lower than aluminium in the electrochemical seriesPb2+ (aq) + Sn (s) → Sn2+ (aq) + Pb (s) is spontaneous because lead is lower than tin in the seriesMg2+ (aq) + Ag (s) → Ag+ (aq) + Mg (s) is not spontaneous because magnesium is above silver in the series.Lean more: https://brainly.com/question/24556237

why do you think that sodium chloride has to be heated to 800c before melting, but candle wax will start to melt at 50c?
Answer:
Sodium chloride is an ionic compound which makes it stronger and have a higher melting and boiling point. Candle wax is a covalent compound so it has a low melting point.

How many moles are in 6.20 x 10^24 molecules of H2O?
Answer:
10.3 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
[tex]n = \frac{6.20 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 10.299003[/tex]
We have the final answer as
10.3 molesHope this helps you
A wind turbine transfers energy from
energy stores. What one word
completes the sentence?
Answer:
The word "transfers" completes the sentence.
Explanation:
A wind turbine transforms the mechanical energy of wind into electrical energy. A turbine takes the kinetic energy of a moving fluid, air in this case, and converts it to a rotary motion. As wind moves past the blades of a wind turbine, it moves or rotates the blades. These blades turn a generator.
Hope This Helps!
Answer:
The right answer is "kinetic"
Explanation:
Wind is moving, so has kinetic energy.
Jax designs an expierment to determine how the amount of sodium chloride affects the boiling point of water which is the independent /manipulated variable
Answer:
The amount of sodium chloride.
Explanation:
This is because an independent/manipulated control is something that is changed or controlled by the experimenter. Jax has control over the change of sodium, therefore the answer is the amount of sodium chloride.
