Which group on the periodic table ways to lose electrons?
Answer:
Elements that are metals tend to lose electrons and become positively charged ions called cations. Elements that are nonmetals tend to gain electrons and become negatively charged ions called anions. Metals that are located in column 1A of the periodic table form ions by losing one electron.

What is the volume of kristas rock
Answer : The volume of kristas rock is 30 mL.
Explanation :
From the given image we conclude that:
Initial volume of liquid = 150 mL
Final volume of liquid = 180 mL
Now we have to determine the volume of kristas rock.
Volume of kristas rock = Final volume of liquid - Initial volume of liquid
Volume of kristas rock = 180 mL - 150 mL
Volume of kristas rock = 30 mL
Therefore, the volume of kristas rock is 30 mL.

Which of the following is true about the picture above? What would it be?
Answer:
Container A is a solution and Container B is a colloid.
Explanation:
Container A is a solution as the tyndall efffect is not present. You cannot see the light bean through the glass.
Container B is a suspension or a colloid as you can see the beam through the glass.
The first option proposes Container A is a colloid...this is not correct
The third option is not true as the tyndall effect is only displayed in container B
The fourth option is not correct the tyndall effect is not present in container A meaning it would not be a suspension or a colloid and you can see the tyndall effect in container B indicating its not a solution

how many picoliters are in 3.16 mL
Answer:
3.16×10⁹ pL
Explanation:
Given data:
Volume in mL = 3.16
Volume in picoliters = ?
Solution:
Picoliter and milliliters are units of volume. Milliliter is greater unit than picoliter.
1 mL = 10⁹ pL
Now we will convert the 3.16 mL into pL.
3.16 mL × 10⁹ pL/ 1 mL
3.16×10⁹ pL
What is the mass in grams of each of the following?
a. 2.50 mol of sulfur, S

a) 80
b) 36
c)6
d)64
All in grams
the formula ; n= m
M
was used .
where n is moles
m is mass of a substance
M is molar mass
The mass of the substance is the product of the moles and the molar mass. The mass of sulfur = 80 gm, calcium = 72 gm, carbon = 6 gm, and copper = 201.6 gm.
What is mass?Mass of any substance is the amount of the constituent particle it holds together and can be measured in grams. The mass has been calculated from the moles of the substance and its molar mass.
The mass of sulfur is calculated as,
Mass = moles × molar mass
= 2.50 mol × 32 g/mol
= 80 gms
The mass of calcium is calculated as,
Mass = moles × molar mass
= 1.80 mol × 40 g/mol
= 72 gms
The mass of carbon is calculated as,
Mass = moles × molar mass
= 0.50 mol × 12 g/mol
= 6 gms
The mass of copper is calculated as,
Mass = moles × molar mass
= 3.20 mol × 63 g/mol
= 201.6 gms

What is menstruation?
Menstruation (also known as a period, among other colloquial terms) is the regular discharge of blood and mucosal tissue from the inner lining of the uterus through the vagina. The menstrual cycle is characterized by the rise and fall of hormones. Menstruation is triggered by falling progesterone levels and is a sign that pregnancy has not occurred.
The first period, a point in time known as menarche, usually begins between the ages of 12 and 15.Menstruation starting as young as 8 years would still be considered normal.The average age of the first period is generally later in the developing world, and earlier in the developed world. The typical length of time between the first day of one period and the first day of the next is 21 to 45 days in young women. In adults, the range is between 21 and 31 days with the average being 28 days.

A student drops a 95g object into a graduated cylindor that has 30ml of water in it. After the object is added to the cylinder the water level reads 63ml. What is the density of the object?
Answer:
The answer is 2.88 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
From the question
mass = 95g
volume = final volume of water - initial volume of water
volume = 63 - 30 = 33 mL
We have
[tex]density = \frac{95}{33} \\ = 2.87878787...[/tex]
We have the final answer as
2.88 g/mLHope this helps you

5. The diagram above shows what happened when an irregular solid was immersed in water. This irregular solid has the same mass as a gold block, which is 2 cm wide by 2 cm high by 5 cm long. Using the method described in the passage, compare the density of the unknown with the density of gold.
A. Equal to gold
B. Less than gold
C. Greater than gold
D. Cannot be determined
The density of the unknown will be greater than the density of gold.
An overview will be given since the diagram isn't given. The formula to calculate the density of an irregular shape will be the mass divided by the volume.
The density is the mass per volume. From the information given, since they've the same mass, then it means that the volume of the gold will be more than the volume of the unknown. Therefore, the density of the unknown will be greater than gold.
