If a block has the mass of 15.00 grams and measurements of 5.00cm by 3.00cm by 2.00cm what is the volume of the block?

Chemistry

Answer:

Volume = 30cm³

Explanation:

A block is a geometrical figure and its volume, -look at the figure-, follows the equation:

Volume = Width*Length*Height

As the measurements of the block are 5.00cm, 3.00cm and 2.00cm, the volume is:

Volume = 5.00cm*2.00cm*3.00cm

<h3>Volume = 30cm³</h3>

Explain why can two nonmetals bond together, but two metals cannot? A) Metals will only form covalent bonds. B) Nonmetals can sh
erma4kov [3.2K]

Answer: C) Non-metals can share pairs of electrons and form covalent bonds

Explanation: The principal reason why it is non-metals that can form covalent bonds is because of their electronegativities. Electronegativity is the tendency of an atom to attract electrons towards itself.

The participating atoms in a covalent bond have to be able to hold the shared electron in place & it is this attraction towards the centre of each participating atom that holds the electrons in place. Metals aren't electronegative, they don't attract electrons towards each other, they'd rather even push the electrons away from themselves (electropositive) to be stable. The closest concept of metals to shared electrons is in metallic bonding, where metals push and donate their valence electrons to an electron cloud which is free to move around the bulk of the metallic structure. But this is nowhere near the type of bonding that exist in covalent bonds.

For a different reaction, the plot of the reciprocal of concentration versus time in seconds was linear with a slope of 0.056 M-
Bond [772]

Answer:

C_t=0.165M

Explanation:

From the question we are told that:

Slope K=0.056 M-1 s -1

initial Concentration C_1=2.2M

Time t=100

Generally the equation for Raw law is mathematically given by

\frac{1}{C}_t=kt+\frac{1}{C}_0

\frac{1}{C}_t=0.056*100+\frac{1}{2.2}_0

C_t=0.165M

Match each statement with a layer of the atmosphere. There will be two statements for each layer.
LuckyWell [14K]

<u>The troposphere: </u>

H. This layer can have thunderstorms or clear, sunny skies.

A. The biosphere interacts most with this layer. 

<u>The stratosphere:</u>

B. It is the second layer from Earth's surface. 

G. Winds are strong and steady in this layer. 

<u>The mesosphere:</u>

E. It is heated by the ozone layer beneath it. 

D. This layer is where most meteor showers occur. 

<u>The thermosphere :</u>

F. It contains the ionosphere and exosphere. 

C. It contains layers of single, unmixed gas. 

<u>Explanation:</u>

Depending on the Earth's  temperature the atmosphere can be separated into layers. The troposphere, the stratosphere, the mesosphere and the thermosphere are those layers. The lowest layer is named as Troposphere (0-10 km from the Earth outer surface), it comprises about 75% of the atmosphere's total air and nearly most the water vapor.

Stratosphere (10-30) includes much of the surface ozone. The change in height temperature arises as this ozone absorbs ultraviolet (UV) radiation from the sun. The temperature in Mesosphere (30-50 Km) declines again with height, hitting a minimum of about -90 ° C at the "mesopause." Above this thermosphere (50-400 Km) is settled which is a area where temperatures rise with height once again. The penetration of intense  UV and X-ray radiation from the sun induces this temperature rise.
