Answer:

they grow, reproduce and die.

Explanation:

Microorganisms are a way of life that cannot be visualized without the aid of a microscope. These tiny beings can be found in the air, on the ground, and even in man. These tiny beings are not all the same, they can be very different in size and way of life. However, they all have in common a very simple structure and the impossibility of being seen without the use of a microscope. In addition, microorganisms can represent some characteristics of life, since as well as living beings in gereal they grow, reproduce and die.

I'm looking at the barometer in my lab as I type this question. It says the pressure is 968 torr. What is this pressure expresse

Ksenya-84 [330]

Answer:

1.27 atm.

Explanation:

The following data were obtained from the question:

Pressure (P) in torr = 968 torr

Pressure (P) in atm =...?

Thus, we can convert from torr to atm by doing the following:

Recall:

760 torr = 1 atm

Therefore,

968 torr = 968/760 = 1.27 atm

Therefore, 968 torr is equivalent to 1.27 atm.

A reaction occurs when one compound reacts and is broken down into different elements or simpler compounds.

Inessa [10]

Answer:

Decomposition Reaction

Explanation:

If you are referring to what type of reaction that occurred then the answer would be decomposition reaction.

This is a chemical reaction where one reactant is broken down into two or more products.

REACTANT → PRODUCT

AB → A + B

The products can be two or more elements or two or more compounds, depending on what was decomposed.

A copper cylinder, 12.0 cm in radius, is 44.0 cm long. If the density of commoner is 8.90 g/cm3, calculate the mass in grams of

inna [77]

The mass of the copper cylinder is 177065.856g

Given:

Radius of the copper cylinder R=12cm

Height of the copper cylinder H=44cm

Density of the cylinder=8.90 $\frac{g}{c m^{3}}$

To find:

Mass of the copper cylinder

<u>Step by Step by explanation:</u>

Solution:

According to the formula, Mass can be calculated as

$\rho=\frac{m}{v}$ and from this

$m=\rho \times v$

Where, m=mass of the cylinder

$\rho$ =density of the cylinder

v=volume of the cylinder

And also cylinder is provided with radius and height value.

So volume of the cylinder is calculated as

$v=\pi r^{2} h$

Where $\pi$ =3.14

r=radius of the cylinder=12cm

h=height of the cylinder=44cm

Thus, $v=3.14 \times 12^{2} \times 44$

v=3.14 \times 144 \times 44

$v=19895.04 \mathrm{cm}^{3}$

And we know that, $m=\rho \times v$

Substitute the known values in the above equation we get

$m=8.90 \times 19895.04$

m=177065.856g or 177.065kg

Result:

Thus the mass of the copper cylinder is 177065.856g
