Write the net ionic equation for the reaction of sodium chloride with magnesium hydroxide. Include the complete ionic equation and label spectator ions. Also be sure to label the reactants and products as solid, liquid, gas, or aqueous solutions.

Answers

Answer 1
Answer: This a long process...
first you write down the equation,in this case:
2NaCl (aq) + Mg(OH)2 (s) ———> MgCl2 (aq) + 2NaOH (aq) .
next you break them up into ions :
(only break up the aqueous solutions)
(2Na+) + (2Cl-) + Mg(OH)2 {leave it together} ———> (Mg2+) + (2Cl-) + (2Na+) + (2OH-).
then look at both sides of equation and cancel the ions that appear twice .
In this case: Cl and Na.
now the remaining is your final net atomic equation:
Mg(OH)2———-> Mg2 + 2OH.

Which fossil fuel is mainly used for heating and cooking? A. electricity

B. coal

C. petroleum

D. natural gas

Answers

Answer: D. natural gas

Explanation:

Fossil fuels are the source of energy that are excavated from the deep layers of the earth crust. They are produced after year long microbial activity over the decayed plant and animal matter. Natural gas is the fossil fuel which is a naturally occurring natural gas which primarily consists of methane, but also contains alkanes, carbon dioxide, hydrogen sulfide, and helium.

It is the most common type of fossil fuel used for heating and cooking purposes. As it is cheapest in price as compared to other fuels and emits less amount of gaseous waste after combustion. Therefore, does not create pollution in house when used for heating and cooking.

Imagine this scenario. All of the trees and plants are removed from a steep mountainside how would the removal of the trees and plants affect the soil on the mountainside

Answers

Answer:

Landslides will occur due to the removal of vegetation

Explanation:

Due to the removal of plants and trees from the slope of the mountain, the soil becomes dry and loses its fertility. This dry soil becomes unstable and when it comes in contact with the water (from precipitation), it causes landslides and the materials are eroded along the slope of the valley. When there is vegetation in the slope it absorbs the water into their roots thereby making the slope stable. So vegetations also is an important factor in controlling slope stability.

The landslide refers to the downward motion of particles including rocks, soils, and debris. It occurs when the shear stress exceeds the shear strength of the material.

So a slope that lacks in the vegetation cover is more likely to experience landslide.

Nothing unless it was dug out from roots if not they would grom back in a long period of time

Consider the following reaction at 25 °C: CaCrO4s)-Ca2*la)+CrO,2(aq) Ko 7.1 104 What are the equilibrium concentrations of Ca2 and CrO42?

Answers

Answer: The equilibrium concentration of are 0.0266 M.

Explanation:

The chemical equation for the ionization of calcium chromate follows:

The expression for equilibrium constant is given as:

We are given:

The concentration of solid substances are taken to be 1. Thus, they do not appear in the equilibrium constant expression.

Let the equilibrium concentration for be 'x'

Putting values in above equation, we get:

Hence, the equilibrium concentration of are 0.0266 M.

Calculate the molarity of a 10.0% (by mass) aqueous solution of hydrochloric acid.

Answers

Molality  is the measure of concentration of solute in 1 kg of solution. The molality of the solution is 3.05 mol/kg.

10% of HCl (by mass) means 10 g of HCl and in 90 g of water.

Molar mass of HCl = 36.5 g/mol

Molality:

It is the measure of concentration of solute in 1 kg of solution. It can be calculated by the formula.

Where,

m- molality

n - number of moles

w - weight of solvent in grams

Number of moles of HCl

put the value in molality formula,

Therefore, the molality of the solution is 3.05 mol/kg.

a) 0.274 m

b) 2.74 m

c) 3.05 m

d) 4.33 m

e) the density of the solution is needed to solve the problem

Answer:

The molality of a 10.0% (by mass) aqueous solution of hydrochloric acid is 3.05 mol/kg.

Explanation:

10.0% (by mass) aqueous solution of hydrochloric acid.

10 grams of HCl is present in 100 g of solution.

Mass of HCl = 10 g

Mass of solution = 100 g

Mass of solution = Mass of solute + Mass of water

Mass of water = 100 g - 10 g = 90 g

Moles of HCl =

Mass of water in kilograms = 0.090 kg

Molality =

The molality of a 10.0% (by mass) aqueous solution of hydrochloric acid is 3.05 mol/kg.

Answer:

Explanation:

The gas law used to solve the problems is Charles's law . It states with no pressure or energy change, the volume of an ideal gas is directly proportional to its temperature in Kelvin.

A gas occupies 547 L at 331K.

So its volume at 376K is

= 547 / 331 * 376

= 621.37 L

The gas law used to solve the problem is Boyle's law . It states with no temperature or energy change, the volume of an ideal gas is inversely proportional to its pressure.

A gas occupies 97 mL at 130 kPa.

So its volume at 225 kPa is

= 97 * 130 / 225

= 56.04 mL

#1

Apply charles law

#2

Apply boyles law
