You and your roommates have already decided to spend a week volunteering in the relief effort over the winter break, but in orde

r to convince your roommates to write to Congress to demand action on climate change, you want to give them a sense of how much water fell. To do this, you calculate how many gallons of water would be in your dorm room if 52 inches of rain landed in this space. Assume that your dorm room is 228 ft^2 and know that 1 gallon = 231 in^3 and that 1 foot = 12 inches.

Answer:

Gallons of water in the dorm room =7391 gallons

Explanation:

<u>Given:</u>

Amount of rainfall = 52 inches

Area of the room = 228 ft^2

<u>To determine:</u>

The gallons of water in the room

<u>Calculation:</u>

Convert area of room from ft^2 to inches^2

1 foot = 12 inches

Therefore, 1 ft^{2} = (12\  in)^{2} = 144\ in^{2}

Area of room is:

\frac{228ft^{2}*144in^{2}}{1ft^{2} } =32832in^{2}

Volume of water in the room is:

=Area\ of\ room * Amount\ of\ rainfall\\\\= 32832 in^{2} * 52\ in = 1707264\ in^{3}

Convert from in^3 to gallons:

1 gallon = 231 in^3

Therefore:

\frac{1707264in^{3} * 1 gallon}{231in^{3}} =7391 gallons

Answer:

1= Magnesium

2 = Option 3 =  1s² 2s² 2p⁶

Explanation:

An electrically neutral atom consist of equal number of protons and electrons.

The answer for 1st q is magnesium because the electronic configuration showed twelve number of electrons. The atomic number of magnesium is twelve that's why this configuration is of Mg.

Mg₁₂ =  1s² 2s² 2p⁶ 3s²

The second answer is option three because has atomic number ten and third electronic configuration have ten electrons.

Ne₁₀ = 1s² 2s² 2p⁶

It is stable electronic configuration. Neon is inert because of this electronic configuration. The outer most shell is completely filled.

What is the specific heat capacity of an unknown metal if 75.00 g of the metal absorbs 418.6J of heat and the temperature rises
EleoNora [17]

Answer:

The specific heat capacity of the unknown metal is 0.223 \frac{J}{g*C}

Explanation:

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

There is a direct proportional relationship between heat and temperature. The constant of proportionality depends on the substance that constitutes the body as on its mass, and is the product of the specific heat by the mass of the body. So, the equation that allows calculating heat exchanges is:

Q = c * m * ΔT

where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.

In this case, you know:

  • Q= 418.6 J
  • c= ?  
  • m= 75 g
  • ΔT= 25 C

Replacing:

418.6 J= c* 75 g* 25 C

Solving:

c=\frac{418.6 J}{75 g*25 C}

c= 0.223 \frac{J}{g*C}

<u><em>The specific heat capacity of the unknown metal is 0.223 </em></u>\frac{J}{g*C}<u><em></em></u>

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

Does someone know the combustion in a jacket potato???
Leya [2.2K]

Answer:

Some varieties of potato, such as Russet and King Edward, are more suitable for baking than others, owing to their size and consistency. Despite the popular misconception that potatoes are fattening, baked potatoes can be part of a healthy diet.[2]

When I2 and FeCl2 are mixed together, iodine (I) cannot replace chlorine (Cl) in the compound because iodine is lower on the per
andrezito [222]

The given statement is True.


This is single replacement reaction.

As reactivity decreases down the group,

Iodine is less reactive than Chlorine.  

And so Iodine cannot replace chlorine from FeCl2.

I2 + FeCl2 ---> no reaction (Iodine is less reactive than chlorine)
