what volume of liquid is in the graduated cylinder
​

Answer:

I will need  six (6) bags of potting soil

Explanation:

Since you plan on planting in 10 pots and need 15 cups of potting soil per pot, the total amount of potting soil you need (in cups) is 10 X 15 = 150 cups of potting soil.

We have that a bag contains 25 sups. to get the number of bags needed, we have to divide 150 by 25. This will give us 150 / 25 = 6 bags.

Therefore, I will need  six (6) bags of potting soil

Answer: science is the systematic way of gaining knowledge about nature

Answer:

-32 Fahrenheit converts to 237.594 Kelvin

The day is the independent variable and the mileage is the dependent variable. Thus option B is correct.

Variables are the measurable parameter can be manipulated and controlled in research. For example person's eye color, its value can be changed from brown to blue depend on different factors.

An independent variable is a single character where Age is an example of an independent variable and dependent variable depend on other variable like it can be changed by other components.

Control variable remain constant and show no effect on other variables. It is used to prevent bias in an experiment. An intervening variable or mediator variable  is another variable can modify the relationship between dependent and independent variables.

Thus option B is correct.

Answer:

The answer is below

Explanation:

When estimating significant numbers, the following applies:

i) All non zero digits are significant

ii) Zeros before non zero digits are not significant

iii) Zeros placed between non zero digits are significant

iv) Trailing zeros to the right of decimals or trailing zeros in whole number are significant.

When estimating, we use the number with the highest number of significant figure.

a)  97.381 ÷ 4.2502 + 0.99195

=22.912098 + 0.99195 = 23.90405 to 5 s.f

b)  171.5 + 72.915 – 8.23    (72.915 has 5 s.f)

= 236.185 to 3 s.f

c)  1.00914 ÷ 0.87104 + 1.2012        (1.00914 has 6 s.f)

= 2.35975 to 6 s.f

d) 21.901 – 13.21 – 4.0215     (21.901 has 5 s.f)

= 4.4895 to 5 s.f

i WOULD LIKE Nanopesticides

Nano-formulated pesticides can deliver active ingredients where they are needed without polluting the environment or – like neonicotinoids have been accused to do – indiscriminately kill essential wildlife. And more efficient agrochemicals are urgently needed to support a global population that will reach 10 billion by 2050.

So far, only a few studies have shown that nanoagrochemicals are actually more efficient than their traditional counterparts, and none of them have been tested in the field yet.

Answer:

We can calculate the energy of a photon in two ways. If you already know the frequency, f, of the photon in Hz, then use E = hf. Another form of Planck's equation uses the simple relationship that c = λ f, where λ is the wavelength of the photon

hope this helped good luck!

Answer:

Explanation:

the energy of photon can be determined by the formula that is

E=hf where h is plancks constant and its value is 6.63*10^-34 j.s and f is the frequency of photon to find out the frequency we have to divide the energy of photon by plancks constant

f=E/h

Answer:

54.21 mL.

Explanation:

We'll begin by calculating the number of mole in 0.242 g calcium carbonate, CaCO3.

This is illustrated below:

Mass of CaCO3 = 0.242 g

Molar mass of CaCO3 = 40 + 12 +(16x3) = 40+ 12 + 48 = 100 g/mol

Mole of CaCO3 =?

Mole = mass /Molar mass

Mole of CaCO3 = 0.242/100

Mole of CaCO3 = 2.42×10¯³ mole.

Next, we shall write the balanced equation for the reaction. This is given below:

CaCO3 —> CaO + CO2

From the balanced equation above,

1 mole of CaCO3 decomposed to produce 1 mole CaO and 1 mole of CO2.

Next, we shall determine the number of mole of CO2 produced from the reaction.

This can be obtained as follow:

From the balanced equation above,

1 mole of CaCO3 decomposed to produce 1 mole of CO2.

Therefore,

2.42×10¯³ mole of CaCO3 will also decompose to produce 2.42×10¯³ mole of CO2.

Therefore, 2.42×10¯³ mole of CO2 were obtained from the reaction.

Finally, we shall determine volume occupied by 2.42×10¯³ mole of CO2.

This can be obtained as follow:

1 mole of CO2 occupies 22400 mL at STP.

Therefore, 2.42×10¯³ mole of CO2 will occupy = 2.42×10¯³ x 22400 = 54.21 mL

Therefore, 54.21 mL of CO2 were obtained from the reaction.

Answer: 5390 cg/mm³.

Explanation:

To convert: 539 dag/dm³ to cg/mm³.

Since 1 dag = 1000 cg  ( where dag= Dekagram and cg = Centrigram)

and 1 dm = 100 mm  (where dm = decimetre , mm= millimetre)

Then,

[tex]539\text{ dag/dm}^3=\dfrac{539\times1000}{100}\text{ cg/mm}^3\\\\=5390\text{ cg/mm}^3[/tex]

Hence,  539 dag/dm³ = 5390 cg/mm³.

Answer:

395.84cm³

Explanation:

V= π r² h

V= 3.14 6² 3.5

V= 3.14 36 3.5

V= 395.84

The volume of the air inside the cylinder is 395.64 cubic centimeters.

Given:

A cylinder container is filled with air. Its radius is 6.00 cm and its height is 3.50 cm.

To find:

The volume of the air inside the cylinder.

Solution:

The radius of cylinder = r = 6.00 cm

The height of the cylinder = h = 3.50 cm

The volume of the cylinder = V

The volume of the cylinder is given :

[tex]V=\pi r^2 h\\\\V=3.14\times (6.00 cm)^2\times 3.50 cm\\\\V=395.64 cm^3[/tex]

The volume of the air in cylinder = V = [tex]395.64 cm^3[/tex]

The volume of the air inside the cylinder is 395.64 cubic centimeters.

The chemical property of combustion.

Explanation:

Combustion is a chemical reaction that occurs between a combustible material, a substance that causes or favors the combustion of other substances that is oxidizer and oxygen, all this accompanied by outgoing energy in the form of heat (exothermic energy) and incandescent energy.

In this case, wood is the combustible material, and combustion is generated by separate energy, fire, phosphors, sparks.
