a. 2.50 mol of sulfur, S
b. 1.80 mol of calcium, Ca
c. 0.50 mol of carbon, C
d. 3.20 mol of copper, Cu

Answers

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

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? ​

Answers

Answer:

The answer is 2.88 g/mL

Explanation:

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/mL

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.

The answer is going to be C hope this helps please make me a Brainly

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.

Not all protists use flagella or cilia to move. Give an example of another way protists move and identify the type of protist that uses that mode of movement.​

Answers

Answer: One of the most striking features of many protist species is the presence of some type of locomotory organelle, easily visible under a light microscope. A few forms can move by gliding or floating, although the vast majority move by means of “whips” or small “hairs” known as flagella or cilia, respectively. (Those organelles give their names to informal groups—flagellates and ciliates—of protists.) A lesser number of protists employ pseudopodia. Those same organelles may be used in feeding as well.

What is the volume of kristas rock

Answers

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.

How are electrically neutral atoms different than they form

Answers

A normal atom has a neutral charge with equal numbers of positive and negative particles. That means an atom with a neutral charge is one where the number of electrons is equal to the atomic number. Ions are atoms with extra electrons or missing electrons.

An atom is said to be electrically neutral if it has an equal amount of protons and electrons. On the other hand, an atom is electrically charged if its protons and electrons are not distributed evenly.

What are neutral atoms?

Neutral atoms are defined as when an atom has an equal amount of protons and electrons, it also has an equal number of electric charges, both positive and negative. As a result, every element in the periodic table has a neutral atomic structure.

Normal atoms have an equal amount of positive and negative particles and a neutral charge. Accordingly, an atom with a neutral charge is one in which the atomic number is matched by the number of electrons.

Thus, an atom is said to be electrically neutral if it has an equal amount of protons and electrons. On the other hand, an atom is electrically charged if its protons and electrons are not distributed evenly.

'B' are mixed at 25°C and the volume of
solution was measured to be 44.8 cm3
then correct reaction is
(A) A Hmix = 0, solution shows
ideal

Answers

Answer:

The correct option is;

(B) [tex]\Delta H_{mix} < 0[/tex], solution shows negative deviation

Explanation:

The given parameters are;

The available volume of liquid A = 25 cm³

The available volume of liquid B = 20 cm³

The volume of the solution (mixture) = 44.8 cm³

Therefore, we have;

[tex]\Delta _{mix} V < 0[/tex]

Which is one of the prerequisite for the formation of negative deviation

When a non-ideal solution shows negative deviation according to Raoult's Law, we have;

[tex]\Delta _{mix} H < 0[/tex], we have more heat released due to new molecular interactions.

how many picoliters are in 3.16 mL

Answers

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
