GEIGER COUNTERS

A device that permits determination of alpha and beta radiation emitted from a substance  

BOTH

Film sensitive to radiation that is removed and developed to measure exposure  

NEITHER

A device used for monitoring individual cumulative exposure to ionizing radiation  

NEITHER

Explanation:

1. Geiger counters and scintillation counters can be described by statements 1 and 2.

2. Statement 3 refers to film-based radiation detectors, not Geiger counters or scintillation counters.

3. Statement 4 refers to dosimeters, not Geiger counters or scintillation counters.

1. An amplifying device that indicates the presence of ionizing particles: This statement describes both Geiger counters and scintillation counters. Both types of counters use amplifying devices to detect and indicate the presence of ionizing particles.

2. A device that permits determination of alpha and beta radiation emitted from a substance: This statement describes both Geiger counters and scintillation counters. Both types of counters are capable of detecting alpha and beta radiation.

3. Film sensitive to radiation that is removed and developed to measure exposure: This statement describes neither Geiger counters nor scintillation counters. Instead, it refers to film-based radiation detectors, such as photographic film or thermoluminescent dosimeters (TLDs), which are used to measure radiation exposure.

4. A device used for monitoring individual cumulative exposure to ionizing radiation: This statement describes neither Geiger counters nor scintillation counters.

Answer:

The answer is 3%

Explanation:

Answer:

This all should be correct:

c

a

c

a

Answer:

C, A, B, B

Explanation:

Question 1: C. inner core

Why? Because the inner core is literally the center of the Earth. Meaning it is the hottest part of the Earth.

Question 2: A. crust

Why? The crust is the outer most layer which is the layer we walk on so to speak. The Earth can be broken up into four layers and as said before the crust is the outer part of it. It is actually amounts to less than 1% of Earth's volume.

Question 3: B. basalt

Why? If we were to average the oceanic crust we would get something around six kilometers and this is the thickness. This is mostly made up of basalt.

Question 4: B. outer core

Why? Due to difference in pressure and temperature the outer core tends to release dense matter which sinks while warm (less dense rises). This causes the Coriolis force, resulting from the Earth's rotations.

The mass of solute required in each case can be obtained form the stoichiometry of the reaction.

We know that the mass of each solution can be obtained from the relation;

mass/molar mass = concentration × volume

mass = concentration × volume × molar mass

a)

mass =  0.125 M  ×  1.00 L ×  174 g/mol = 21.75 g

b) mass = 0.015 M  × 375 /1000 × 42 g/mol = 0.24 g

c) mass = 0.350 M × 500/1000 × 180 g/mol =31.5 g

Answer:

1.1 mol/liter

Explanation:

You would use the M1V1 = M2V2 equation to solve this.

We know M1 is 3.0 M, V1 is 25 milliliters, and V2 is 68 milliliters. We need to find M2.

To find M2, first plug in what you know.

(3.0 M)(25 mL) = M2(68 mL)

Then, divide everything by 68 mL to get M2 by itself

Your answer should be a quite large decimal but I rounded it to 1.1 mol/liter.

Answer:

The concentration of sodium chloride is 1.1 moles/liter.

Explanation:

Answer:

yes

Explanation:gergrgregbfbwerbebw

Answer:

What that means is that when pressure and number of moles are kept constant, increasing the temperature will result in an increase in volume. Likewise, a decrease in temperature will result in a decrease in volume. In your case, the volume of the gas decreased by a factor of about 3, from "140.0 mL" to "50.0 mL".

Answer:

2MnO2 + H2O => Mn2O3 + 2OH is the correct balanced equation.

When manganese oxide reacts with water to form a different manganese oxide and hydroxide, the correct balanced equation for this is 2MnO₂ + H₂O ⇾ Mn₂O₃ + 2OH.

The term balance chemical equation is define as the equation which satisfy the law of conservation of mass, i.e., “Total mass of the products is equal to the total mass of all the reactants”.

If a chemical equation is not balanced, it will break the law of conservation of mass. It will indicate that either mass is created or destroyed, which is impossible.

Balanced chemical equations have the equal number and type of each atom on both sides of the equation.  

Thus, When manganese oxide reacts with water to produce a different manganese oxide and hydroxide, the correct balanced equation for this reaction is 2MnO₂ + H₂O ⇾ Mn₂O₃ + 2OH.

deforestation i hope this helps

Answer:

Deforestation and Cultivation

Explanation:

First I am going to give the definition of deforestation:

Deforestation is basically the removal of trees.

The removal of trees leaves leaves very little vegetative cover to hold heavy rain fall. This is why mudslides and things happen. When the land is clear and flat, the water keeps on going instead of going into the soil. That water that keeps on going is called runoff water. If we planted trees by the rivers, that could take down the height of the floods in towns by 20%

At first I was going to say widening rivers, but that is a way to manage river water. When we lengthen the river, it is so that the water can take more time to reach the river canal.

Definition of Cultivation: The production of food by preparing the land to grow crops (especially on a large scale) animal husbandry - breeding and caring for farm animals. agriculture, tree farming - the cultivation of tree for the production of timber.

I was also going to say Cultivation. Over-cultivation is the excessive use of farmland to the point where productivity falls due to soil exhaustion or land degradation. Now this is actually why we have floods in the USA. The soil cannot soak up any water, therefore the water over flows and that is when a flood starts to happen.

I know this took some time but hope I could help :)

Answer:

Ba²⁺ + CO₃²⁻ → BaCO₃

Explanation:

A net ionic equation is a way to write a chemical reaction in which you list only the species that are participating in the reaction.

For the reaction:

Ba²⁺ + 2NO₃ + 2Na⁺ + CO₃²⁻ → BaCO₃ + 2Na⁺ + 2NO₃

As you can see, NO₃ and Na⁺ are not participating in the reaction. Thus, net ionic equaation is:

Ba²⁺ + CO₃²⁻ → BaCO₃

Complete Question

Consider the total ionic equation below.

[tex]Ba^{2+} + 2NaO_3^{1 -} + 2Na^{+} + CO_3^{2-} ----> BaCO_3 + 2Na^{+} + 2NO_3^{1-}[/tex]

Which is the net ionic equation for the reaction?

A [tex]Ba^{2+} _{(aq)} + CO_3 ^{2-} _{(aq)} ----> BaCO_3_{(s)}[/tex]

B [tex]2Na^+ + CO_2 ----> Na2CO3[/tex]

C [tex]NO3 + Na ^ + ----> NaNO3[/tex]

D   [tex]Ba_2^+ + 2NO3 ----> Ba(NO3)2[/tex]

Answer:

Option A is the correct option

Explanation:

The given ionic equation is

       [tex]Ba^{2+} + 2NaO_3^{1 -} + 2Na^{+} + CO_3^{2-} ----> BaCO_3 + 2Na^{+} + 2NO_3^{1-}[/tex]

Looking at this complete ionic equation we see that [tex]Na^{+1} \ and \ NO_3^{1-}[/tex] did not change in the reaction so they will not be included in the net ionic equation so the net ionic equation becomes

         [tex]Ba^{2+} _{(aq)} + CO_3 ^{2-} _{(aq)} ----> BaCO_3_{(s)}[/tex]

red car will travel a much farther distance and at a faster speed as opposed to the blue car

Explanation:

Based on the information provided within the question Jenna can expect to observe that the red car will travel a much farther distance and at a faster speed as opposed to the blue car which will travel a shorter distance and at a lower speed. This is mainly because Jenna is applying an increased amount of force on the red car thus creating more acceleration and ultimately increasing the distance.

See answer below

Explanation:

I have to answer this question in english because is the rule here. I hope you can understand this.

Now, in order to answer this, is really easy. We already have the quantity of SO₂ in the air of a city. This concentration is 14 mg/m³, so we want to know the quantity in 1 L. This quantity can be expressed in mass.

If concentration according to the units is: mg/m³ This means that we have units of mass and volume. So, in order to know the quantity of SO₂ in mass, we need to convert the units of volume m³ to liter.

1 m³ is covered in 1000 L, therefore:

14 mg/m³ * 1 m³/1000 L = 0.014 mg/L

Then, the mass will be:

m = 0.014 mg/L * 1 L

m = 0.014 mg of SO₂

This is the quantity of SO₂ in 1 L.
