Several atoms bonded together is called a

Which would melt first, the element

balandron [24]

Explanation:

First, get both values into the same units

To covert from Kelvin to degrees C, subtract 273.15

1210 - 273.15 =936.85

Melting point of germanium=936.85 degrees C

Melting point of gold= 1064 degrees C

Therefore germanium would melt first because it has the lower melting point.

How do i make homemade cookies without a mix

OLga [1]

<h2>ingredients:</h2>

2 ¾ cups all-purpose flour

1 teaspoon baking soda

½ teaspoon baking powder

1 cup butter, softened

1 ½ cups white sugar

1 egg

1 teaspoon vanilla extract

Explanation:

Step 1

Preheat oven to 375 degrees F (190 degrees C). In a small bowl, stir together flour, baking soda, and baking powder. Set aside.

Step 2

In a large bowl, cream together the butter and sugar until smooth. Beat in egg and vanilla. Gradually blend in the dry ingredients. Roll rounded teaspoonfuls of dough into balls, and place onto ungreased cookie sheets.

Step 3

Bake 8 to 10 minutes in the preheated oven, or until golden. Let stand on cookie sheet two minutes before removing to cool on wire racks.

Partner Tip

Reynolds® Aluminum foil can be used to keep food moist, cook it evenly, and make clean-up easier.

Why is CF4 a non polar molecule, even though it contains polar bonds?

adell [148]

The molecule is symmetric, a tetrahedron. Thus, the 4 polar bonds cancel each other out. (It is easier to see with a one dimensional molecule like CO2, which is linear with the C in the middle. The 2 polar bonds cancel each other.

A noble gas is placed in a 10.0 liter container. the noble gas has a mass of 25.25 g, the pressure is 3.05 atm, and the temperat

valina [46]

The problem can be solved using Ideal Gas Equation.

The equation is given below.

$PV= nRT$

Step 1 : Calculate moles of the gas (n)

Where P = pressure of the gas in atm = 3.05 atm

V = Volume of the gas in Liters = 10.0 L

n = number of moles of the gas

R = Gas constant = 0.08206 L-atm/mol-K

T = Temperature of the gas in Kelvin

To convert T from Celsius to Kelvin unit, we add 273

Hence we have T = 24 + 273 = 297 K

Let us plug in the above values in ideal gas equation

$(3.05 atm) ( 10.0 L) = n (0.08206 L.atm/mol.K) ( 297 K)$

$n = \frac{(3.05atm) (10.0L)}{(0.08206 L-atm/mol) (297)}$ ... Unit K gets cancelled

$n = 1.25 mol$

Number of moles of gas are 1.25

Step 2 : Find molar mass using mol value

Mole and molar mass can be related to each other by the following expression

$Mole = \frac{Mass (grams)}{Molar mass}$

The mass of the gas is given as 25.25 g

moles (n) = 1.25 mol

After plugging the values we get,

$1.25 mol = \frac{25.25g}{Molar mass}$

Molar mass = $\frac{25.25g}{1.25mol}$

Molar mass = $20.2g/mol$

Molar mass of the gas is 20.2 /mol

Step 3 : Find identity of the gas using periodic table

From the periodic table , we can see that noble gas Neon has molar mass 20.18g/mol .

Hence the given gas is Neon which is represented by the symbol is "Ne"

30 POINTS !!!!!!

Katen [24]

I know it's only 5 points but heres the answer
<span>1. It depends what type of method you are using. if it is Height x Width x Length then it will not work for an irregular shape because it has extra pieces that would not be included.

2. The second method would work for both regular and irregular shapes because you would have to know or find out the volume of the regular shape to get the volume for the irregular shape.

3. It also depends on what you are doing, if you are doing a regular shape then use the first method, if it's an irregular shape then use the second method, if you do the maths correctly both should give you an accurate answer for what you want to achieve.

4. No, because the sugar would dissolve.

5. No, on this case the displacement method would not work because of the weight difference

I hope this helps you a bit.</span>
