First we calculate how many moles of MgBr₂ are required to create such a solution, using the definition of molarity and the given volume and concentration:

Now we convert 13.5 moles of MgBr₂ into grams, using its molar mass:

Answer:

Updrafts characterize a storm's early development, during which warm air rises to the level where condensation begins and precipitation starts to develop. In a mature storm, updrafts are present alongside downdrafts caused by cooling and by falling precipitation.

Because Aluminum atoms tend to lose electrons in order to achieve an insert gas configuration. The aluminum atoms need to lose 3 electrons in order to attain the neon configuration , so it forms a trip of positive action

Answer:

Aluminium & Phosphorus (C & D)

Explanation:

Both these elements need to form positive ions with a +3 charge as they need to lose their 3 electrons to form a stable state in their configuration.

Answer:

If it has to do with heat, it's thermal. ... The Greek word therme, meaning “heat,” is the origin of the adjective thermal. Something that is thermal is hot, retains heat, or has a warming effect.

Answer:

B. They travel at the same speed through any one material.

Explanation:

Answer:

Oxygen and sulfur have similar chemical properties because both elements have six electrons in their outermost electron shells. Indeed, both oxygen and sulfur form molecules with two hydrogen atoms: water and hydrogen sulfide

Explanation:

Answer:

Carbohydrates can be divided into two main types: simple and complex. Simple carbohydrates are made up of just one or two sugar units, whereas complex carbohydrates are made up of many sugar units.

Answer:

we find the mass for each element in one mole by multiplying the number of atoms in one molecule with the atomic mass

mC=8Ac=8*12=96g

mH=10AH=10*1=10g

mN=4AN=4*14=56g

mO=2AO=2*16=32g

by adding the masses together we find the molar mass of the molecule

M=mC+nH+mN+mO=96+10+56+32=194g/mole

we apply the rule of threes to find the percentage of each element

194g..96gC..10gH...56gN....32gO

100g....a...........b...........c.............d

a=(100*96)/194=49.48%C

b=(100*10)/194=5.19%H

c=(100*56)/194=28.85%N

d=(100*32)/194=16.48%O

Explanation:

Answer:

Demonstrate familiarity with the pH scale ... body (excluding things like stomach acid) measure around 7.2 and 7.6 on the pH scale (a 7 is neutral on the scale). ... The pH of a solution is a measure of its acidity or alkalinity (base). ... Using a pH meter, you find the pH of an unknown solution to be 8.0.

Explanation:

Answer:

7 is neutral, acids are 1-6, bases are 8-14. Pure water has a pH of 7, where as almost everything else is either an acid or a base.

Answer:

455.4 mmHg

Explanation:

To solve this problem we can use Gay Lussac's Law, which describe the temperature and pressure of a gas, at constant volume and composition:

In this case:

We input the data:

And solve for P₂:

Answer:

2.1 atm

Explanation:

We are given the following variables to work with:

Initial pressure (P1): 2.5 atm

Initial temperature (T1): 320 K

Final temperature (T2): 273 K

Constant volume: 7.0 L

We are asked to find the final pressure (P2). Since volume is constant, we want to choose a gas law equation that relates initial pressure and temperature to final pressure and temperature. Gay-Lussac's law does this:

[tex]\frac{P_{1}}{T_1} =\frac{P_{2}}{T_2} \\[/tex]

We can rearrange the law algebraically to solve for [tex]P_{2}[/tex].

[tex]{P_{2}} =\frac{(T_2)(P_{1} )}{T_1} \\[/tex]

Substitute your known variables and solve:

[tex]P_2 = \frac{273K(2.5atm)}{320K} = 2.1 atm[/tex]

Word Equation

Lead Nitrate + Sodium Chloride --> Lead Chloride + Sodium Nitrate

Balanced Chemical Equation

2 NaCl (aq) + Pb(NO3)2 (aq) → PbCl2 (s) + 2 NaNO3 (aq)

Ionic Equation

In an ionic equation, the aqueous species in the reaction are broken up into ions.

2Na⁺ + 2Cl⁻  + Pb²⁺  + 2NO₃⁻  → PbCl2 (s)  + 2Na⁺ +  2NO₃⁻

Answer:

Uranium is produced by mining deposits of this mineral found in earth's crust

Answer:

You need 8 electrons to make a stable energy level. If you have any less, it won't make it "happy" per say, and with more it will make it happier but its probably safer to use the 8!
