Answer:

D

Explanation:

because it has two or more properties

Answer:

It's a soft metal, reactive and with a low melting point, with a relative density of 0,97 at 20ºC (68ºF). From the commercial point of view, sodium is the most important of all the alkaline metals. Sodium reacts quickly with water, and also with snow and ice, to produce sodium hydroxide and hydrogen.

Step 1: Define

0.41 mol CaO

2.5 M Solution

Step 2: Identify Conversions

1000 g = 1 kg

Molar Mass of Ca - 40.08 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of CaO - 40.08 + 16.00 = 56.08 g/mol

Step 3: Convert

Step 4: Check

Follow sig fig rules and round. We are given 2 sig figs as our lowest.

0.024114 kg CaO ≈ 0.024 kg CaO

Answer:

0.172 Kg

Explanation:

Given data:

Kg of solvent = ?

Moles of solute = 0.43 mol

Molality = 2.5 m

Solution:

Formula:

m = moles / Kg of solvent

by putting values,

2.5 m = 0.43 mol / kg of solvent

Kg of solvent = 0.43 mol / 2.5 m

Kg of solvent = 0.172 Kg

The average speed of the toy car : 0.2 m/s

Given

The motion of a toy car

Required

The average speed

Solution

Average speed = total distance/total amount of time ,

From the graph :

Total distance travelled : 4

Total time : 20 s

The average speed = total distance (d) : total time (s)

The avg speed = 4 : 20

The avg speed = 0.2 m/s

Answer: Salts

Explanation: Salts easily dissolve in water. Salts are always ionic bonds, meaning they dissolve easily.

Ice does not technically dissolve in water since ice is made of water. You can't dissolve a substance in itself.

Metals are obviously not able to dissolve either in water.

Oils do not mix with water, they float on water, meaning they are immiscible.

explanation

EF = C4H5ON2

molar mass= 4 (12.01) + 5 (1.9) +16 + 2 (14.01) = 97.11 glmol

Explanation:

The cell theory states that all biological organisms are composed of cells; cells are the unit of life and all life come from preexisting life. The cell theory is so established today that it forms one of the unifying principles of biology.

Headaches forced onto me. I was forced out of the womb by two women. My mother and my mother's doctor. I was held in adults arms and I hated it. I had to do whatever they said. I had these diapers around my bo.oty and they were so uncomfortable. I got older and I don't know why I listened to country.  The only country song I like now is God Made Girls by Rae Lynn. I got older and started asking what inappropriate words meant. My parents told me the exact meanings and didn't censor. I was disgusted and stayed silent for hours. Now I'm my current age and I need to do about 5 math assignments each day all due at 11:59 pm or else they're missing and I have no excuses. I don't get them at all either there's not explanations.  In conclusion, life is headaches forced onto me.

P₂O₅ is an empirical formula

Given

compounds

Required

an empirical formula

Solution

The empirical formula is the smallest comparison of the atoms forming the compound.

Molecular formulas are formulas that show the number of atomic elements that make up a compound.

(empirical formula) n = molecular formula

1. P₂O₅ : the ratio of compounds cannot be further reduced to whole numbers⇒empirical formula

2. P₄O₆ : molecular formula

(P₂O₃)₂=P₄O₆

P₂O₃ : empirical formula

3.C₂H₄ : molecular formula

(CH₂)₂=C₂H₄

CH₂ : empirical formula

4. C₃H₆ : molecular formula

(CH₂)₃=C₃H₆

CH₂ : empirical formula

Answer:

Acid reacts with water?

Explanation:

Answer:

The radius of an atom can only be found by measuring the distance between the nuclei of two touching atoms, and then halving that distance. The type of atomic radius being measured here is called the metallic radius or the covalent radius depending on the bonding.

Answer:

0.02740 moles ZnCl2

0.8777 moles ZnCl2

Explanation:

a) How many moles of ZnCl, can be made from 1.7g of Zn?

First we need to convert from grams of Zn to moles of Zn, and then from moles of Zn to moles of ZnCl.

We will use the atomic weight of Zn to do this..

Atomic weight is 65.38 g Zn/1 mol Zn, this can also be written as

1 mol Zn/65.38mol Zn... We will now convert:

1.76 g Zn *  [tex]\frac{1 mol Zn}{65.38 g Zn}[/tex] = 0.0273784032 moles Zn

Now we'll use the balanced chemical equation to convert from moles of Zn to moles of ZnCl..

Zn + 2HCl -> ZnCl2 + H2

We can see that for every mol of Zn that reacts, 1 mol of ZnCl2 is produced..

So:

0.0273784032 moles Zn * [tex]\frac{1 mol ZnCl2}{1 mol Zn}[/tex] = 0.0273784032 moles ZnCl2

This can be estimated to 0.0274 moles ZnCl2

__________________________________________________________

b) If 6.4 grams of HCl are used in this reaction, how many moles of ZnCl, are

produced?

First we need to convert form grams of HCl to moles of HCl, and then to moles of ZnCl...

We'll do this using the atomic weight of HCl (36.458 g/mol or 1 mol/36.458 g)

6.4 g HCl * [tex]\frac{1 mol HCl}{36.458 g HCl}[/tex] = 0.1755444621 mol HCl

Now we'll use the balanced chemical equation to convert from moles of HCl to moles of ZnCl..

Zn + 2HCl -> ZnCl2 + H2

We can see that for every 2 moles of HCl that react, 1 mol of ZnCl2 is produced..

So:

0.1755444621 mol HCl * [tex]\frac{1 mol ZnCl2}{2 mol HCl}[/tex] = 0.877722311 moles ZnCl2 are produced.

This can be estimated to 0.8777 moles ZnCl2

Answer: 6m/s

Explanation:

Speed is calculated as distance divided by time. Therefore, the speed of the traveling puck would be calculated as the distance travelled by the hockey puck divided by the time taken. This will be:

= 18m / 3s

= 6m/s

The answer is 6 meters per second
