Which phrase describes neap tides?
A.) occur four times a day
B.) produce extra-low tidal ranges
C.) caused only by the pull of the moon
D.) occur at the same time as spring tides
NEED YOUR HELP.
Answer:
The answer is B
Explanation:
Neap tides are a type of to tie occuring after spring tides. It occurs when moon and sun are at the right angles to each other. It produce low tidal ranges. Hence, phrase B is correct.
What are tides ?Tides are a geographical phenomenon taking place due to the gravitational pull by sun and moon on the ocean of earth. They are long period waves causing the ocean back and forth to the cost.
During new moons larger tides appears in earth and they are called spring tides. Spring tides occurs twice in a lunar month. During spring tides, moon appears full and earth is between sun and moon.
After seven days of spring tide, lower tides are produced when the moo and sun comes in right angle to each other. They are called the neap tides producing lower range of tidal waves . During this time moon will be half full thus for the first and last quarter of the moon. Hence, the option B neap tide produce low tidal ranges is correct.

Answer:
2 Nitrogen
Explanation:
This is because it says Diammonium Hydrogen Phosphate. Here. (NH4)3PO4 is one way to write this. However, another way to write this is (NH4)2HPO4. There should be in fact two ammonium groups, NH4 and 1 Hydrogen to get 3+ charge to balance the 3- charge from the Phosphate.
a typical baseball has a mass of 350g and takes up a volume of .780L. what is the density of a baseball in g/l and g/ml?
Answer:
449 g/L
0.449 g/mL
Explanation:
Step 1: Given data
Mass of a typical baseball (m): 350 gVolume of a typical baseball (V): 0.780 LStep 2: Calculate the density (ρ) of the baseball in g/L
The density is equal to the quotient between the mass and the volume.
ρ = m / V
ρ = 350 g / 0.780 L
ρ =449 g/L
Step 3: Convert ρ from "g/L" to "g/mL"
We will use the conversion factor 1 L = 1000 mL.
449 g/L × (1 L/1000 mL) = 0.449 g/mL

Here are the answers:
1.) land
2.) water
3.) warmer
4.) rises
5.) sea
Explanation:
During a day at the beach, the land heats up faster than the water. Because of this, the air over land rises over the land and the cooler, more dense air, blows into the ocean, creating a sea breeze.
What is the law of conservation of matter?
A.Matter can never be changed.
B.Matter can never mix or rearrange.
C.Matter cannot be created or destroyed.
D.matter will always break down.
Considering the definition of the law of conservation of matter, the law of conservation of matter establishes that matter cannot be created or destroyed (option C).
Law of conservation of matterThe law of conservation of matter holds that, within a closed system, the amount of matter involved in a chemical reaction is constant, meaning a closed system means an environment that isolates the components involved in the reaction from the outside.
In other words, this law establishes that the mass of the reactants consumed is equal to the mass of the products obtained, even though they have been transformed into each other.
In other words, the law of conservation of matter states that matter is neither created nor destroyed during a chemical reaction, it is only transformed.
SummaryIn summary, the law of conservation of matter establishes that matter cannot be created or destroyed (option C).

3. What noble gas would be part of the electron configuration notation for Mn?
Answer:
Argon {Ar}
Explanation:
The noble gas used for a condensed electron configuration is the one before the element which you are configuring.
In this case, the element (Mn) is manganese
The noble gas that is before this element is Argon which is the row above it
so your configuration would be {Ar} 3d^5 4s^2

Why is the primary standard, KHP, used in the determination of the molar mass of an acid?
Potassium acid phthalate will serve as our primary standard. This is a large molecule (KHC8H4O4) with a molar mass of 204.2 g/mol. Instead of writing the whole formula, we abbreviate it as KHP, where "P" stands for the phthalate ion, C8H4O42-, not for phosphorus. KHP is an acidic substance, with the ionizing hydrogen being set forward in the formula for emphasis. Therefore, KHP is monoprotic and will react with NaOH in a simple 1 to 1 relationship according to the following equation:
2. The new element Odessium (Od) was discovered in 2020 by Mr. Green. It has three isotopes: Od-284
(34.60%), Od-285 (21.20%), and Od-288 (44.20%). What is its average atomic mass?|
Answer:
Odessium (Od) has an average atomic mass of 284.45
Explanation:
Average mass is calculated from the isotopes of an element weighted by their relative abundance.
To calculate the relative average mass, you need to find the % of each isotope and use these to calculate the relative average mass
(34.60 %)/100 x 284=96.73(21.20 %)/100 x 285=60.42(44.20 %)/ 100 x 288=127.296Add all 3 answers to get the relative average mass
96.73 + 60.42 + 127.296= 284.45it supports respiration.

Explanation:
How many grams of Al are needed to react with 91.8 grams of FeO
3FeO + 2Al —> 3 Fe +Al2O3
Answer:
Ans : 22.86 gm of Aluminium
Solution,
3FeO + 2Al ---> 3 Fe + [tex]Al_{2}O_{3}[/tex]
Given 3 2
Find 1.27 x
By the given gms of FeO find its mole and put the moles in the find,
[tex]n = \frac{given mass}{molecular mass}[/tex]
Given mass of FeO is 91.8
Molecular mass of FeO is 71.8
n = [tex]\frac{91.8}{71.8}[/tex]
n = 1.27 moles of FeO
Now solve for x,
[tex]x = \frac{2 x 1.27}{71.8}[/tex]
x = 0.85 moles
These are just moles of Aluminium that we need to react with FeO, so to find Grams of Aluminium we need,
Mass = moles x molecular mass
Mass = 0.85 x 27(atomic mass of Al)
Mass = 22.86 grams of aluminium is what we need

Magnesium forms a __ion and wants to (gain/
lose) __electrons. Bromine forms a ___ ion and wants to (gain/lose)
electrons.
Answer:
Magnesium forms a positive ion and wants to lose electrons. Bromine forms a negative ion and wants to gain electrons.
Answer:
Magnesium forms a positive ion (Mg²+) and wants to lose two electrons.
Bromine forms a stable noble gas electronic
configuration when it gains one electron. Thus we find
magnesium as 2+ cation and bromine as a 1- anion in a
1:2 ratio in the compound .
Also, bromine forms a negative ion.
