The body regulates those levels in an example of homeostasis. When levels decrease, the parathyroid releases hormones. If calcium levels become too high, the thyroid helps out by fixing calcium in the bones and lowering blood calcium levels. The nervous system helps keep homeostasis in breathing patterns.

Explanation:
How much water must be added to 40.0 g of CaCl2 to produce a solution that is 35.0 wt% CaCl2?
The mass of water present in the solution is 21.5 g.
What is concentration?Concentration refers to the amount of solute in a solution. There are various ways of expressing concentration such as;
Molar concentrationMass concentrationPercentage concentrationWe have the following information;
Percent concentration = 35.0 %
mass of solute = 40.0 g
Mass of water = ?
So;
35 = x/40 + x × 100/1
35 = 100x/40 + x
35(40 + x) = 100x
1400 + 35x = 100x
1400 = 100x - 35x
1400 = 65x
x = 1400/65
x = 21.5 g
Hence the mass of water is 21.5 g.

The equilibrium constant for the reaction shown below is Kc=0.0091. If the equilibrium concentrations of A and B are 0.031 M and 0.0823 M, respectively, what is the equilibrium concentration of C?
Answer:
[tex][C]=0.0221M[/tex]
Explanation:
Hello there!
In this case, according to the given chemical reaction at equilibrium:
[tex]3A\rightleftharpoons 3B+2C[/tex]
It is possible for us to set up the equilibrium expression as shown below:
[tex]Kc=\frac{[B]^3[C]^2}{[A]^3}[/tex]
Whereas Kc, [A] and [B] are known as 0.0091, 0.031M and 0.0823M and it is required to calculate [C]; thus, we solve for it as follows:
[tex][C]^2=\frac{[A]^3Kc}{B]^3}[/tex]
[tex][C]=\sqrt{\frac{(0.031)^3*0.0091}{(0.0823)^3}}[/tex]
[tex][C]=0.0221M[/tex]

The speed of sound in water is 350m/s. If a sound wave has the frequency of 50Hz.
What would the wavelength of the wave be?
Answer:
Explanation
Let, Wavelength = W,
Given, frequency (f) = 50 Hz, wave velocity (V) = 342 m/s
We know, V = f × W
=> 342 = 50 × W
=> W = 342/50 metre
=> W = 6.84 metre

A student adds 5400.0mL of 0.15M NaOH to 201.2mL of 4.0M NaOH. What is the final [NaOH]?
Answer:
0.287 M
Explanation:
Multiply the concentration of each solution by the volume of each (in liters) to get the moles of NaOH in that solution.
0.15 M • 5.4000 L = 0.81 mol NaOH
4.0 M • 0.2012 L = 0.80 mol NaOH
Add the mol of NaOH together to get the total --> 0.81 + 0.80 = 1.61 mol NaOH
Divide by the total volume of solution (5400.0 mL + 201.2 mL = 5,601.2 mL = 5.6012 L)
1.61 mol / 5.6012 L = 0.287 M NaOH

When we look at heat transfer problems that include phase transitions, there can bemanynec-essary steps. Consider a material of massmthat undergoes two phase transitions: from solid toliquid and then from liquid to gas. It starts at an initial temperature ofT0(well below the meltingtemperature ofTm) and it heated until it is a gas at a temperature ofTf(well above the boilingtemperature ofTv). How many different steps (simple temperature changes or phase transitions)of heat transfer would you need for this problem
Answer:
There would be 3 temperature changes and 2 phase transitions
Explanation:
The temperature of the material would first increase from T0 to Tm (its melting point)- This is one temperature change.
It would the change from solid to liquid at its melting point Tm.- This is one phase transition.
Its temperature would then increase from its melting point Tm to its boiling point Tv -This is another temperature change.
It would then change from liquid to gas at its boiling point Tv - This is another phase transition.
Finally, its temperature would then increase from its boiling point to T(f) - This is the third temperature change.
So, there would be 3 temperature changes and 2 phase transitions

Please someone help me and all of the terms do not have to eh used
Answer:
The correct answer is -
1. D. mold
2. A. Cast
3. F. trace fossil
4. C. original material fossils
5. B. fossil record.
Explanation:
Mold is the impression of an organism in a rock that occurs due to the complete dissolving of the organism and only an impression left in sedimentary rocks.
The cast is a fossil copy of an organism in a rock that takes place when water-containing minerals fill the molds and creates a three-dimension copy of the fossil.
Trace fossils are the fossils that are preserved in such a manner that records of biological activity stored only instead of remains of plants or animals.
Storing originals animals or parts of the remaining such as tissue of an organism in natural form is known as original-material fossils.
Fossil records are the fossils ever found or discovered on the earth.

A 4.00g sample of gas is found to exert a pressure of 1.71 atm when confined in 3.60L container at a temperature of 24
Answer:
There are 0.311 moles of gas in the tank
Explanation:
Complete question
A 4.00g sample of gas is found to exert a pressure of 1.71 atm when confined in 3.60L container at a temperature of 241 K. Find the number of moles of the gas
Solution
As we know
[tex]PV = nRT[/tex]
where P is the pressure of the gas in atm
V is the volume in liters
n is the number of moles
R is the gas constant = 0.08206 L·atm/K·mol
and T is the temperature in Kelvin
Substituting the given values in above equation, we get -
[tex]1.71 * 3.60 = n * 0.08206 * 241\\n = 0.311[/tex]
There are 0.311 moles of gas in the tank
An unknown amount of sodium azide (NaN3) reacts and produces 0.033 moles of nitrogen gas. What mass of sodium metal is produced
Answer:
Mass of sodium metal is 130.87 gram
Explanation:
The complete reaction is
2 NaN3 --> 2 Na + 3 N2
We know that PV = nRT
n = [tex]\frac{PV}{RT}[/tex]
On substituting the given values, we get
[tex]n = \frac{\frac{99707}{101325}*75 }{0.082 *(273.15 +15)} \\n = 3.02[/tex]moles of N2
Sodium azide's molar mass
3.02 *(2/3) = 2.013 moles
Mass = 2.03 * 65.01 = 130.87 gram

What do plants do that requires Energy?
Answer:
Photosynthesis
Explanation:
Photosynthesis uses energy from light to convert water and carbon dioxide molecules into glucose (sugar molecule) and oxygen. The oxygen is released, or “exhaled”, from leaves while the energy contained within glucose molecules is used throughout the plant for growth, flower formation, and fruit development.
