Answer:
D. A neap tide is the period halfway between tides when the tide changes direction. (correction) Answer : C
Explanation:
Process of elimination can be used. First off, A is incorrect because neap tides have the smallest tidal range ; spring tides would fit this choice. B is incorrect since neap tides are specific to the first, and third quarter moons when the sun and moon are right angles. C is wrong because it is the other way around since high tides are a little higher than average and low tides are a little lower than average (correction) this is correct since higher low tides and lower high tides are closer together and have a smaller tidal range than standard tides(spring tides) with higher high tides, and lower low tides. D is correct because they occur halfway between the spring tides (correction): incorrect since a neap tides occur around a week(7 days) after a spring tide(moderate tides). There is no evidence this is true.
There are three patterns: diurnal(one high and low tides a day), semidiurnal(two high and low tides a day), and mixed(two high and low tides a day of different lengths).
The spring and neap tides are the types of tides involved with the low and high tides.

The reaction in which methane is burned, CH4 +202 --> 2H20 + CO2, is an example of a
combustion reaction
O synthesis reaction
O decomposition reaction
O precipitate reaction
Answer: Combustion
Explanation:
Methane gas or natural gas is the hydrocarbon that reacts with oxygen as shown below: CH4 + 2O2 → CO2 + 2H2O There are two types of combustion reactions: complete and incomplete combustion. Therefore there are four products, carbon dioxide, water, carbon, and carbon monoxide.
Which of the following is the least likely to remain homogeneous?
. O A. All of these
O B. A supersaturated solution
O C. An unsaturated solution
O D. A saturated solution
Answer:
all

Explanation:
An acid-base reaction of (r)-sec-butylamine with a racemic mixture of 2-phenylpropanoic acid forms two products having different melting points and somewhat different solubilities. Draw the structure of these two products. How are the two products related? Be sure to answer all parts.
Answer:
See explanation
Explanation:
When an optically active compound reacts with a racemic mixture, two different products appear .
Hence, when (R)-sec-butylamine reacts with a racemic mixture of 2-phenylpropanoic acid as shown in the image attached.
Enantiomers are optical isomers which are mirror images of each other. The image attached was obtained from Bartleby.
An atom is the simplest substance known and provides the building block from which all matter is composed.

9. What is the density of brass, a copper-zinc alloy, if a block displacing 40.8 cm3 weighs 324 grams?
Answer:
The answer is 7.94 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
From the question
mass = 324 g
volume = 40.8 cm³
We have
[tex]density = \frac{324}{40.8} \\ = 7.941176...[/tex]
We have the final answer as
7.94 g/cm³Hope this helps you
what is ohm's law? in simple terms please. I dont know but This is what I said, formulas to determine the voltage, resistance or the current. Is this right?
Answer: Your answer was pretty close, but we could make it better! Simply put, ohm's law states that by doubling the voltage across a circuit, the current will also double. You could also say that it was a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit, or (E = IR). Hope this helps!

a cylindrical object has a diameter of 1.25 cm and a height of 6.48 cm. what is its volume?
The volume of cylinder = 7.948 cm³
Further explanation
Volume is a derivative quantity derived from the length of the principal
The unit of volume can be expressed in liters or milliliters or cubic meters
The volume of the aquarium is almost the same as the beam namely:
V = length x width x height
The volume of a cylinder can be formulated :
[tex]\tt V=\pi.r^2.h[/tex]
r = radius
h = height
radiusDiameter of cylinder = 1.25 cm
radius=r :
[tex]\tt \dfrac{1.25}{2}=0.625~cm[/tex]
volume[tex]\tt V=\pi\times 0.625^2\times 6.48\\\\V=\boxed{\bold{7.948~cm^3}}[/tex]
describe the purpose of using a chemical equation.
Answer:
The purpose of using a chemical equation is to keep track of elements and the number of atoms of each of the elements on each side of the equation. ... They use symbols and formulas to show the chemical reaction so that chemical names do not need to be written out.
Answer:
:0
Explanation:
Sample Response: Chemical equations show how chemicals interact when a reaction occurs. They use symbols and formulas to show the chemical reaction so that chemical names do not need to be written out. They also help keep track of all elements and the number of atoms of each element on each side of the equation.
Is NaBr+I2 -> NaI+Br2 a single replacement
Is not a single replacement
Further explanationA single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds
Reactions
A+BC--> AC+B
Metal halogens can force metal halide ions in the order F> Cl> Br> I
Oxidation : F₂> Cl₂> Br₂> I₂
Reaction
NaBr+I₂ -> NaI+Br₂
Then the reaction will not occur because I₂ cannot oxidize Br, or the reaction is said to be non-spontaneous
Elena held a rock weighing 1 N in her hand. The rock has no velocity.
KE________?
KE = 0
Further explanationEnergy is the ability to do work
Energy because its motion is expressed as Kinetic energy (KE) which can be formulated as:
[tex]\large{\boxed{\bold{KE=\frac{1}{2}mv^2}}}[/tex]
So for two objects that have the same speed, the greater the mass of the object, the greater the kinetic energy
The stone in hand is in a motionless state (at rest) so that its velocity (v) = 0, so it has no kinetic energy
But this stone can have potential energy that is gained due to its height

The discovery of optics gave scientists instruments such as microscopes and telescopes.
Explanation:
The period between the 16th-8th century was called the period of the scientific revolution. At this time, the foundations of our modern science was laid.
One of the characteristic of this period was the emphasis on the scientific method which upheld results from reproducible experiments.
Nicolaus Copernicus, Francis Bacon and Isaac Newton were leading names in this period.
It was within this period that the discovery of optics gave scientists instruments such as microscopes and telescopes and scientific examination of the celestial bodies was launched.
