c.fusion, because the reaction formed lighter nuclei

d.fission,because the reaction formed heavier nuclei

PLEASE HELP :)which Type Of Reaction Is Shown In The Diagrama. Fusion, Because The Reaction Released

Answers

Answer 1

Answer:

b.fission, because the reaction absorbed energy

Explanation:

Answer 2

The reaction is shown in the diagram is fission. because the reaction absorbed energy. Therefore, option B is correct.

What is fission ?

The process of nuclear fission involves the splitting of an atom's nucleus into two or more smaller nuclei. Even by the energetic standards of radioactive decay, the fission process releases a very high quantity of energy and frequently results in gamma photons.

By dissolving large, heavy atoms, like uranium, into smaller ones, like iodine, caesium, strontium, xenon, and barium, to name just a few, fission produces energy. However, fusion involves joining light atoms, such as the deuterium and tritium isotopes of hydrogen, to create the heavier helium.

Nuclear fission is used by all nuclear power plants, and uranium atoms are typically used in nuclear power plants. A neutron splits a uranium atom when it collides with it during nuclear fission, releasing a significant quantity of energy.

Thus, option B is correct.

Answers

When CuSO​4​​⋅​ 5H​2​O is heated in a crucible, there is a loss of water. Subtract the mass of the CuSO​4​⋅ 5H​2​O from the mass of CuSO​4 to determine the amount of water lost. Therefore, option B is correct.

What do you mean by the compound ?

A substance made up of two or more components is called a compound. Table salt, water, and carbon dioxide are a few examples of compounds.

Chemical substances have no electrical charge. In most cases, ionic compounds are created when a metal interacts with a nonmetal. The reaction between two nonmetals produces covalent compounds.

Elements are unadulterated substances made up of only one kind of atom. Compounds are substances that are created when two or more different types of elements are chemically combined in predetermined ratios.

To determine the amount of water lost subtract the mass of the CuSO​4​⋅ 5H​2​O from the mass of CuSO​4.

This group of fungi has reproductive cells with flagella so that they can swim

Answers

Answer:

The answer would be chytrids.

Chytridiomycota (chytrids) is a group of fungi that has reproductive cells with flagella so that they can swim.

What is Chytridiomycota?

The fungus known as the amphibian chytrid fungus only infects frogs. A frog uses its skin to maintain homeostasis. The chytrid fungus ruins the frog's ability to swallow, exchange ions, and function normally when it affects its skin.

The fungus targets the keratin-containing areas of a frog's skin. Frogs have trouble breathing because they use their skin for respiration.

As a class of fungi, chytrids are regarded as the most basic. They are primarily aquatic, and the only fungus cells known to contain flagella are those of the gametes. They can reproduce asexually or sexually; the latter method produces zoospores.

Therefore, a class of fungi known as chytrids possesses reproductive cells with flagella that allow them to swim.

if the volume and Kelvin temperature are reduced by one-half what will happen to the pressure???

Answers

Answer:

Explanation:

Ideal gas law is valid only for ideal gas not for vanderwaal gas. The pressure will remain same as the initial pressure on decreasing volume and temperature by half.

What is ideal gas equation?

Ideal gas equation is the mathematical expression that relates pressure volume and temperature. real gas can become ideal gas at low pressure and high temperature.

Mathematically the relation between Pressure, volume and temperature can be given as

PV=nRT

where,

P = pressure of  gas

V= volume of  gas =1/2V

n =number of moles of  gas

T =temperature of  gas =T/2

R = Gas constant = 0.0821 L.atm/K.mol

Substituting all the given values we get

P×(V/2)=nR(T/2)

(PV)/2=(nRT)/2

PV=nRT

Therefore, the pressure will remain same as the initial pressure  on decreasing volume and temperature by half.

155.0-ml of a solution of 0.75 M HNO3 is combined with 270 g of magnesium. What
volume of hydrogen gas will be produced at STP?

Answers

Answer:

The volume occupied by the gas is 1.302 × 10⁻³ m³

Explanation:

2HNO₃(aq) + Mg(s) → Mg(NO₃)₂ + H₂(g)

From the above reaction, we have that 2 moles of HNO₃ combine with 1 mole of Mg to produce 1 mole of Mg(NO₃)₂ and 1 mole of H₂

In the question, we have 155.0 mL of a solution of 0.75 M HNO₃ combining with 270 g of magnesium

Therefore, number of moles of HNO₃ = 0.75×155.0/1000 = 0.11625 moles

[tex]Number \, of \, moles \ of \ magnesium = \frac{Mass \ of \, magnesium}{Molar \, mass \ of \, magnesius} = \frac{270}{24.305} = 11.11 \ moles[/tex]

Therefore, HNO₃ is the limiting reaction, hence;

0.11625 moles of HNO₃ will react with 1/2×0.11625 moles or 0.058125 moles of Mg to produce 0.058125 moles of H₂

Hence since we now know the volume of H₂ produce, we can find the volume occupied at STP by the following universal gas equation relationship;

PV = nRT

Therefore;

[tex]V = \frac{n \times R \times T}{P}[/tex]

Where:

V = Volume of occupied by the gas = Required quantity

n = Number of moles = 0.058125 moles

R = Universal gas constant = 8.3145 J/(mol·K)

T = Temperature of the gas at STP = 273.15 K

P = Pressure of the gas at STP = 1 atm = 101325 Pa

[tex]V = \frac{0.058125 \times 8.3145 \times 273.15}{101325} = 1.302 \times 10^{-3} m^3[/tex]

Calcium reacts with a polyatomic ion to form a compound with the general formula Ca(X). What would be the most likely formula for the compound formed between potassium and the polyatomic ion X?

A) K X
B) K2X
C) KX2
D) K2X3
E) K3X2

Answers

Answer:

B) K2X

Explanation:

In an uncharged compound, the total oxidation state must be zero. The oxidation state of the calcium is +2, thus we get the following formula, where x is the oxidation state of the polyatomic ion X:

[tex]x + 2 = 0 \\ x = 0 - 2 \\ x = - 2[/tex]

Also, it is known that potassium has an oxidation state of +1. Since the new compound also has a total oxidation state equal to zero, we get the following equation, where k is the number of K atoms:

[tex]k \times 1 + ( - 2) = 0 \\ k - 2 = 0 \\ k = - ( - 2) \\ k = 2[/tex]

That's how it is found that the compumd consists of 2 K+ ions and one X ion.

An exothermic reaction releases 13,450J of heat. How many calories of energy are released? A) 5 56,274 calories B)1,244 caloriesC) 134,500 caloriesD) 3,215 calories

Answers

Answer:

The correct option is;

D) 3,215 calories

Explanation:

Here we are to convert the units of energy

The given units is in Joules, J, while the required units is in calories, where the calorie is defined as the amount of heat required to raise the temperature of 1 gram of water by 1°C

The conversion formula therefore is 1 calorie = 4.1868 J

Hence, 1 J = 1/4.1868 calories

13,450 J = 13,450 × 1/4.1868 calories = 13,450 /4.1868 calories = 3212.477 calories

∴ 13,450 J ≈ 3,215 calories.

What is the molarity of an HCl solution if 125 mL is neutralized in a titration by 76.0 mL of 1.22 M KOH?

Answers

Answer:

0.74176 M HCl

Explanation:

1) Write out a balanced equation.

  KOH + HCl --> KCl + H2O

2) Calculate #mol KOH in 76.0mL needed for the titration.

 1.22 mol KOH in 1000mL

 x mol KOH in 76.0mL

 x = 0.09272 mol KOH

3) Use the balanced equation ratio (from step 1), 1 mol KOH : 1 mol HCl.

0.09272 mol KOH = 0.09272 mol HCl

4) 125mL of the HCl solution was used for the titration, so find the molarity.

0.09272 mol HCl is in 125mL

x mol HCl in 1000mL

x = 0.74176 mol HCL / 1 L

SO... 0.74176 M HCl is the answer.
