Answer:

Metals are shiny and lustrous with a high density.

They have very high melting and boiling points because metallic bonding is very strong, so the atoms are reluctant to break apart into a liquid or gas.

How many grams of Na2SO4 can be produced from 423.67 g of NaCl?
san4es73 [151]

Mass of  Na2SO4= 514.18 grams

<h3>Further explanation</h3>

Given

423.67 g of NaCl

Required

mass of  Na2SO4

Solution

Reaction

2NaCl + H2SO4 → Na2SO4 + 2HCl

mol NaCl :

= 423.67 g : 58.5 g/mol

= 7.24

From the equation, mol Na2SO4 :

= 1/2 x mol NaCl

= 1/2 x 7.24

= 3.62

Mass  Na2SO4 :

= 3.62 mol x 142,04 g/mol

= 514.18 grams

If I contain 1.86g of krypton gas in a container with a volume of 17.5 liters and at a temperature of 190F, what is the pressure
butalik [34]

Answer:

P = 0.0373 atm

Explanation:

Given data:

Mass of krypton = 1.86 g

Volume of krypton = 17.5 L

Temperature of krypton = 190 F

Pressure of krypton = ?

Solution:

First of all we will calculate the number of moles.

Number of moles = mass/ molar mass

Number of moles = 1.86 g/ 83.9 g/mol

Number of moles = 0.022 mol

Formula:

PV = nRT

P = nRT / V

P =  0.022 mol × 0.0821 atm. L. mol⁻¹. K⁻¹ × 360.928 K /  17.5 L

P = 0.652 atm. L /17.5 L

P = 0.0373 atm

Mobile water supply operations, such as water shuttles or relay pumping, must be performed:_____.
ZanzabumX [31]

Mobile water supply operations, such as water shuttles or relay pumping, must be performed<u> In rural areas without public water </u><u>distribution systems</u>

What operation is the pumping station started at the fire scene to return the water line to the water source? Reverse position. Water extinguishes the fire by absorbing heat and cooling the burning material.

Dry Barrel Hydrant

This type of hydrant is very common in areas with sub-zero weather. In these areas, the hydrant barrel must be dried to prevent the water in the hydrant barrel from freezing.

When should firefighters stop the flow of water from an automatic sprinkler system in a building? After the fire is under control.

If you are involved in a car or vehicle accident, the first thing you should do is call the police. If contacted, police can verify the identity, insurance, and driver's license status of anyone involved with the vehicle. This may seem like a simple step, but it is very important.
