Answer:

increase thickness of insulation

Explanation:

don't increase amount of heating because that's difficult and not efficient.

don't increase surface area of walls because that makes heat be lost quicker.

don't increase windows because windows lose heat worse than walls.

increase thickness of insulation because it's the most effiecient and effective method of keeping heat.

Answer:

There are 0.311 moles of  gas in the tank

Explanation:

Complete question

A 4.00g sample of gas is found to exert a pressure of 1.71 atm when confined in 3.60L container at a temperature of 241 K. Find the number of moles of the gas

Solution

As we know

[tex]PV = nRT[/tex]

where P is the pressure of the gas in atm

V is the volume in liters

n is the number of moles

R is the gas constant = 0.08206 L·atm/K·mol

and T is the temperature in Kelvin

Substituting the given values in above equation, we get -

[tex]1.71 * 3.60 = n * 0.08206 * 241\\n = 0.311[/tex]

There are 0.311 moles of  gas in the tank

Answer:

3.25 M

Explanation:

Number of moles = mass/ molar mass

mass of  NaOH = 65 g

Molar mass of NaOH = 40 g/mol

Number of moles of NaOH = 65g/40 g/mol = 1.625 moles

Let us recall that;

n = CV

n = number of moles of solute

C = concentration of solution

V = volume of solution

C = n/V

n = 1.625 moles

V = 500/1000 L = 0.5 L

C = 1.625 moles/0.5

C = 3.25 M

Answer:

a) 18

b)288g

Explanation:

a) 1:4

4.5mol TiCl4 so HCl is 4(4.5mol)

b) mm of HCl is 36

because 1:4 we multiply 2.0 mol by 4

8mol of HCl

we multiply 8mol by 36 (molar mass of HCl) and we get 288g because mol×molar mass= grams

Answer:

[tex]m_{CO_2}=0.88g[/tex]

Explanation:

Hello there!

In this case, since we are talking about a decomposition reaction whereby calcium carbonate is decomposed to calcium oxide and carbon dioxide according to the following chemical equation:

[tex]CaCO_3\rightarrow CaO+CO_2[/tex]

Next, we must recall the law of conservation of mass which states that matter cannot be neither created nor destroyed so the mass of calcium carbonate equal the addition of the mass of both calcium oxide and carbon dioxide:

[tex]m_{CaCO_3}=m_{CaO}+m_{CO_2}[/tex]

Which must be solved for the mass of carbon dioxide as we are given those of calcium carbonate and calcium oxide:

[tex]m_{CO_2}=m_{CaCO_3}-m_{CaO}\\\\m_{CO_2}=2.00g-1.12g\\\\m_{CO_2}=0.88g[/tex]

Answer:

1. NaCl .

Explanation:

Hello there!

In this case, it is necessary to keep in mind that just ionic compounds are able to conduct electricity and therefore, the more ionic the compound is, the more electricity it conducts. In such a way, we may be able to predict how ionic these compounds are, considering that the electronegativity increases from bottom to top and from left to right.

1. NaCl: this is the most ionic compound since it is at the leftmost group and bonded with chlorine, so this is the most conductive one.

2. Mg(CIO3)2: Mg is bonded to O, not to Cl, which makes the compound ionic but not as ionic as NaCl.

3. NiCl: Ni is more electronegative than Na and Mg, so even when this is ionic, it is not as ionic as NaCl.

4. CaCl2: This is similar to NaCl but since Ca is in group 2A, it is more electronegative than Na, which makes CaCl2 conductive but not as much as NaCl.

Answer:The video shows the electric circuit inside a flashlight. The battery provides power to the circuit. A metal strip is connected to the negative end of the battery. When the flashlight’s switch is pressed, the metal strip moves forward. It touches the metal connected to the bulb near the front. This motion closes the circuit, which creates a path for the electricity and causes the bulb to glow.

Answer:

27.22 dm³

Explanation:

Given parameters:

number of moles = 1 mole

temperature= 50°C, in K gives 50+ 273 = 323K

Pressure= 98.6kpa in ATM, gives 0.973 ATM

Solution:

Since the unknown is the volume of gas, applying the ideal gas law will be appropriate in solving this problem.

The ideal gas law is mathematically expressed as,

Pv=nRT

where P is the pressure of the gas

V is the volume

n is the number of moles

R is the gas constant

T is the temperature

Input the parameters and solve for V,

0.973 x V = 1 x 0.082 x 323

V= 27.22 dm³

Answer is: at lower temperatures the reaction rate would decrease. The lower is the temperature, the slower the reaction becomes. ... Because this is exothermic reaction (enthalpy is less than zero), at lower temperatures, the equilibrium is in favor of ammonia, but the reaction doesn't proceed at a detectable rate.

Hi,

let us go through the question again

N2 + 3H2 ⇌ 2NH3 + energy  

Explain the problem surrounding the ammonia-making process in terms of chemical equilibrium.

So I would approach this question on the basis of effect of each of the reactants and products concentration on the equilibrium synthesis of ammonia.

If the concentration of any reactant is increased, the yield of ammonia is increased.

If the concentration of ammonia is reduced by removing it as it forms, the yield will as well be increased.

This reaction also yields heat meaning it is an exothermic reaction, so when we increase the temperature, the yield will be reduced. Hence it is favored by low temperature.

Answer:

Explanation:

The first thing that you need to do here is to calculate the theoretical yield of the reaction, i.e. what you get if the reaction has a

%

yield.

tells you that every

1

mole of nitrogen gas that takes part in the reaction will consume

3

moles of hydrogen gas and produce

1

mole of ammonia.

In your case, you know that

1

mole of nitrogen gas reacts with

1

mole of hydrogen gas. Since you don't have enough hydrogen gas to ensure that all the moles of nitrogen gas can react

what you need

3 moles H (sub 2)

>

what you have

1 mole H (sub2)

you can say that hydrogen gas will act as a limiting reagent, i.e. it will be completely consumed before all the moles of nitrogen gas will get the chance to take part in the reaction.

So, the reaction will consume

1

Now, you know that the reaction produced

0.50

moles of ammonia. This represents the reaction's actual yield.

In order to find the percent yield, you need to figure out how many moles of ammonia are actually produced for every

100

moles of ammonia that could theoretically be produced.

You know that

0.667

0.50

Explanation:

Convection is a mode of heat transfer in which the particles of a substance actually move from place to place.

During convection, warmer and less dense air rises while colder and denser air sinks downwards under gravity.

Hence; when hot air balloon rises because the fire warms up the air and the air circulates to fill the balloon and lift it at the same time, convection has taken place.

22.9 Liters CO(g) needed

Explanation:

2CO(g)     +   O₂(g)    =>    2CO₂(g)

? Liters          32.65g

                 = 32.65g/32g/mol

                 =   1.02 moles O₂

Rxn ratio for CO to O₂ = 2 mole CO(g) to 1 mole O₂(g)

∴moles CO(g) needed = 2 x 1.02 moles CO(g) = 2.04 moles CO(g)

Conditions of standard equation* is STP (0°C & 1atm) => 1 mole any gas occupies 22.4 Liters.

∴Volume of CO(g) = 1.02mole x 22.4Liters/mole = 22.9 Liters CO(g) needed
