What are the main risk and main benefit when a society uses energy from nuclear fission?
BlackZzzverrR [31]

Answer:

D.

Explanation:

Nuclear energy does not have greenhouse gas emissions. The emissions produced by nuclear fission plants are similar to renewable energy sources.The generation of power using nuclear energy does not affect air quality thus providing a clean source of energy.Nuclear energy originates from radioactive material which are harmful to living organisms.

Determine the Kelvin temperature required for 0.0140 mol of gas to fill a balloon to 1.20L under 0.988 atm a pressure.
Art [367]

Answer:

T = 1031.30 K

Explanation:

Given data:

Temperature of gas = ?

Number of moles of gas = 0.014 mol

Volume of balloon = 1.20 L

Pressure of gas = 0.988 atm

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

T = PV/nR

T = 0.988 atm × 1.2 L / 0.014 mol × 0.0821 atm.L/ mol.K  

T = 1.186 atm. L / 0.00115 atm.L/K

T = 1031.30 K

Compare metals to nonmetals. Include where they are located on the periodic table as well as three properties of each.
Genrish500 [490]

Answer:

Difference between metals and non metals.

1) Metals are good conductors of heat and electricity while non metals are poor conductors.

2) Metals are hard while non metals are soft.

3) Metals have shiny surface while non metals have not.

Examples of metals are sodium and iron while non metals are chlorine and oxygen.

Location in the periodic table.

Metals are present on the left side of the table while non metals are present on the right side of periodic table.

Mass in grams of 6.023×1023 atom of Ca​
Mademuasel [1]

Answer:

\boxed {\boxed {\sf 40.08 \ grams}}

Explanation:

First, find the molar mass of calcium (Ca). This can be found on the Periodic Table.

  • 40.08 g/mol

Next, find the number of moles.

Avogadro's Number tells us the number of atoms in one mole.

  • It is 6.023*10²³

Therefore, there are 6.023*10²³ atoms in 1 mole.

We have 6.023*10²³ atoms of calcium, so it must also be 1 mole of calcium.

Finally, find the mass. Set up a proportion using the molar mass of calcium.

1 \ mol \ Ca * \frac{40.09 \ g}{1 \ mol \ Ca}

Multiply. The moles (mol Ca) will cancel.

1 * 40.08 \ g

40.08 \ g

There are <u>40.08 grams </u>in 6.023*10²³ atoms of calcium.
