Answer:
The lumps should be removed in brown sugar and to be rolled with rolling pin.
Explanation:
In preparing brown sugar as ingredients in baking and pastry, it is important to check if the sugar is lumpy. Although it is not the main ingredient in baking, it is important to check because it could affect the texture of the mixtures. Brown sugar is also much nutritious to white sugar that is why it is more commonly use. The brown sugar become lumpy because when brown sugar is exposed to air it gets harder because the molasses that keeps its soft evaporates that makes the sugar stick together. The rolling pin helps the lump to break up.
What is the name of the process happening in the picture? How do you know it’s that process? Explain your answer in 2 to 3 sentences complete help please
Answer:
The name of the process happening in the picture is explained below in details.
Explanation:
The process in the picture is photosynthesis. The plant is taking CO2 and H2O and using light to form glucose which would be the sugars and creating a byproduct of oxygen that is being released into the atmosphere. How did you know this is photosynthesis? A big thing clearly is the plant and how it’s taking H2O and CO2 and making glucose so it isn’t cellular respiration (if you don’t know what that is don’t worry, if you are learning about this you are bound to come across that later) and it’s releasing oxygen into the atmosphere and light has a function in this process according to the image.

What is the density of an object that has a mass of 28.1g and a volume of 96.2mL? Select the correct answer below: 0.292g/mL 2703g/mL 1.00g/mL 3.42g/mL
Answer:
0.292 g/mL.
Explanation:
From the question given above, the following data were obtained:
Mass of object = 28.1 g
Volume of object = 96.2 mL
Density of object =..?
Density of an object is simply defined as the mass of the object per unit volume of the object. Mathematically, it can be expressed as:
Density = mass / volume
With the above formula, we can obtain the density of the object as follow:
Mass of object = 28.1 g
Volume of object = 96.2 mL
Density of object =..?
Density = mass / volume
Density = 28.1 / 96.2
Density of object = 0.292 g/mL
Thus the density of the object is 0.292 g/mL

222 g of MTBE (CO(CH3)4) are added to gasoline, resulting in a total volume of 2 L of reformulated gas (RFG). Assume that the density of RFG is 0.70 g/mL, and the density of MTBE is 0.74 g/mL. For a-d, determine the concentration of MTBE in the RFG in the following units?
a. mg/L
b. moles/L
c. % (w/w)
d. % (v/v)
e. What is the % (w/w) oxygen in the RFG due to MTBE?
Answer:
Explanation:
From the information given:
(a)
[tex]Concentration \ in \ mg/L = \dfrac{Mass \ of \ MTBE \ in \ mg}{Total \ volume (in \ L)}[/tex]
[tex]Concentration \ in \ mg/L = \dfrac{222 \times 10^3 \ mg}{22}[/tex]
[tex]Concentration \ in \ mg/L = 111 \times 10^3 \ mg/L[/tex]
(b)
[tex]number \ of \ mole s= \dfrac{mass}{molar \ mass } \\ \\ number \ of \ mole s=\dfrac{222 \ g}{88.15 \ g/mol} \\ \\ \mathbf{= 2.518 mol}[/tex]
(c)
[tex]w/w \ percentage = \dfrac{mass \ of \ MTBE }{mass \ of \ solution (RFG)}\times 100\%[/tex]
[tex]where; \\ \\ mass \ of \ (RFG) = 2L \times 0.70 g/mL \\ \\ mass \ of \ (RFG) = 2000 ml \times 0.70 g/mL \\ \\ mass \ of \ (RFG) = 1400 g[/tex]
∴
[tex]w/w \ percentage = \dfrac{222 \ g}{1400 \ g}\times 100\% = \mathbf{15.8\%}[/tex]
(d)
[tex]Volume of MTBE =\dfrac{mass \ of \ MTBE}{density \ of \ MTBE}[/tex]
[tex]Volume \ of \ MTBE = 300 \ mL\\[/tex]
∴
[tex]v/v\% = \dfrac{volume \ of \ MTBE}{volume \ of \ RFG} \\ \\ v/v\% =\dfrac{300 \ mL}{2000 \ mL}\times 100\% \\ \\ \mathbf{v/v\% = 15.00\%}[/tex]
(e)
[tex]From \the \ given \ information; \\ \\ 2.5184 \ moles\ of \ MTBE contain \ 2.5184 \ mole of oxygen[/tex]
∴
[tex]mass of oxygen MTBE = 2.5284 mol \times 16\ g/mol \\ \\ mass of oxygen MTBE = 40.3 9 \ g\\ \\ mass\ of \ RFG = 1400 g[/tex]
∴
[tex]\% w/w = \dfrac{mass \ of \ oxygen}{mass \ of RFG }=\dfrac{40.22 \ g}{1400 \ g} \times 100\%[/tex]
[tex]\% w/w == 2.88\%[/tex]

The total age of 5 children aged 3 years is 50 years. Find the age of the youngest and oldest child?
Answer: See explanation
Explanation:
Here's the correct question:
The total ages of 5 children born at the intervals of 3 years each is 50 years. Find the age of the youngest and the oldest child.
From the information given, we can then make the following assumption with regards to their ages.
First child = y
Second child = y + 3.
Third child = y + 6
Fourth child = y + 9
Fifth child = y + 12
Therefore, y + y+3 + y+6 + y+9 + y+12 = 50
5y + 30 = 50
5y = 50 - 30
5y = 20
y = 20/5
y = 4
Youngest child = 4 years
Oldest child = y + 12 = 4 + 12 = 16 years

Many popular brands of toothpaste contain about 1.00 mg of fluoride per gram of toothpaste. The fluoride compound that is most often used in toothpaste is sodium fluoride, NaF, which is 45% fluoride by mass. How many milligrams of NaF are in a 250.0 g tube of toothpaste
Answer:
Mass of NaF in 250 g tube of toothpaste = 100 mg of NaF
Explanation:
Mass of fluoride per gram of toothpaste = 1 mg
From the given data, the fluoride compound that is most often used in toothpaste is sodium fluoride, NaF, which is 45% fluoride by mass, mass of sodium fluoride per gram of toothpaste can be determined as follows:
1 mg of fluoride per gram of toothpaste = 45% total mass of NaF per gram of toothpaste
100% mass of NaF in toothpaste = 100/45 * 1 mg = 2.22 mg of NaF.
Therefore, mass of NaF per gram of toothpaste is 2.22 mg.
The mass of NaF in 250 g of toothpaste is then calculated below:
In 250 g of toothpaste, mass of NaF = 250 * 2.22 mg = 99.9 mg of NaF

Answer:
C4H10 has a higher boiling point due to stronger dispersion forces
1-butanol has the greater boiling point mainly due to hydrogen bonding influences
Explanation:
If we consider propane and n-butane, we discover that they are both alkanes. However, the magnitude of dispersion forces in alkanes depends on the length of the carbon chain. The greater the length of the carbon chain is greater in n-butane than in propane. The greater the chain length, the greater the magnitude of dispersion forces and the greater the boiling point. Hence, n-butane has a higher boiling point than than propane.
Also, if we compare the boiling points of 1-butanol to that of diethyl ether, we will discover that 1-butanol has a higher boiling point mainly due to intermolecular hydrogen bonding influences.

Why is one side of the moon called "the dark side of the moon"?
Answer:
Option C
Explanation:
The answer is option C or "The amount of time it takes to rotate around it's axis is the same amount of time it takes to revolve around Earth."Remember that the Earth and the Moons amount of time to make a full rotation is almost in sync and they're two sides of the moon, one side we do not see and that's because that side is currently faced away from the Earth which is called the dark side of the moon. Each side has two weeks oh night, and two weeks of day because of how long it takes the moon to revolve, so while we have a side towards the Earth which is illuminated by the sun we have another pointing away in the dark.

(1) Solution A and B are separated by a membrane that is permeable to Mg2 and impermeable to Cl-. Solution A contains 0.1 mM MgCl2, solution B contains 100 mM MgCl2. Mg2 will be at electrochemical equilibrium when solution A is around ____________ mV. 180 mV - 180 mV 90 mV - 90 mV 60 mV - 60 mV
Answer:
90 mV
Explanation:
Faraday constant, F = 96487
Gas constant, R = 8.314
Number of mole of electron transferred, Z = 2
MgCl in solution A, = 0.1 mm
MgCl in solution A, = 100 mm
Using the relation :
E=(RT/ZF) In(Mg out/Mgin)
E = (8.314*298) / (2*96485) * In(100/0.1)
E = (2477.572 / 192970) * 6.9077552
E = 0.0128391 * 6.9077552
E = 0.0886897 V
E = 88.68 mV (approximately 90 mV)

How many atoms are in 123 g of calcium
Answer:
Molar mass of Ca = 40 g / mol , given 123 g Ca is 123/40= 3.075 moles,
1 mole = 6.022 * 10^23 atoms, so 3.075 moles Ca= 18.51*10^23 atoms
Explanation:
The number of atoms present in 123 g of calcium is 18.51 x 10²³ atoms.
What is calcium?Calcium is an element present in the periodic table. It is very much needed for the strength of the bones and teeth.
"Molar mass of many compounds can be calculated by dividing the mass of the compound by the number of moles of the compound."
"The mole is a SI unit of measurement that is used to calculate the quantity of any substance".
First, calculate the moles
Moles = mass / molar mass
Molar mass of Ca = 40 g / mol
Given 123 g Ca is mass
123 / 40 = 3.075 moles,
1 mole = 6.022 x 10²³ atoms,
6.022 x 10²³ is the Avogadro number. It equals to one mole.
So 3.075 moles Ca= 18.51 x 10²³ atoms.
Thus, the number of atoms present in 123 g of calcium is 18.51 x 10²³ atoms.
