Serga [27]3 years ago
5 0

<em><u>Metals </u></em>

- have lustre: they appear shiny

- can conduct heat and electricity

- have a very high melting point

- are malleable(this means they can be hammered without bending)

- have a high density

- can be ductile

- mostly opaque

- make sounds when hit

- corrode easily

<em>Non- metals</em>

- look dull

- don't conduct heat and electricity well

- aren't ductile

- can be at any state at room temperature(solid, liquid, gas)

- mostly transparent


Hope it helps :)

A chemical reaction that is expected to form 325.0 gof product only forms 123.8 g of product. What is the percent yield of this
Tasya [4]

Answer:

\boxed {\boxed {\sf A. \ 38.1 \%}}

Explanation:

Percent yield is the ratio of the amount actually produced to how much could theoretically be produced. It is found using this formula:

\% \ yield = \frac{actual \ yield}{theoretical \ yield} *100

For this reaction, the theoretical or expected yield is 325.0 grams. The actual yield is 123.8 grams.

\% \ yield = \frac{ 123.8 \ g }{325.0 \ g }*100

Divide.

\% \ yield = 0.380923077 *100

\% \ yield = 38.0923077

Round to the nearest hundredth. The 9 in the hundredth place tells us to round the 0 to a 1 .

\% \ yield \approx 38.1

The percent yield is about <u>38.1%</u>

How do glaciers cause erosion and deposition
koban [17]
Like flowing water, flowing ice erodes the land and deposits the material elsewhere. Glaciers cause erosion in two main ways: plucking and abrasion.
Plucking is the process by which rocks and other sediments are picked up by a glacier. They freeze to the bottom of the glacier and are carried away by the flowing ice.
The other way you'll need more informations because my Knowledges are limited by here.

Osmotic pressure ____.a. occurs only in ionic solutions.b. is lower with 1 M NaCl than 1 M sucrose.c. is created using detergent
xenn [34]

Answer:

d. is the hydrostatic pressure produced on the surface of a semi-permeable membrane by osmosis.    

Explanation:

Osmosis -

It is the flow of the molecules of solvent from a region of higher concentration towards the region of lower concentration via a semipermeable membrane , is known as osmosis.

Osmotic pressure -

It refers to the minimum amount of pressure , which is required to be applied to the solution in order to avoid the flow of pure solvent via the semipermeable membrane , is referred to as osmotic pressure.

Or in simple terms ,

Osmotic pressure is the pressure applied to resists the process of osmosis.

Hence ,

From the given options in the question,

The correct option regarding osmotic pressure is d.
