A calcium atom differs from a calcium ion in that the atom has a greater

A)
number of electrons

B)
number of protons

C)
atomic number

D)
mass number

Answers

Answer:

A) number of electrons

Explanation:

A calcium atom has 20 electrons while a calcium ion has 18 electrons since it loses 2 electrons to form a stable octet structure. The formula of a calcium ion is Ca2+.

The number of protons does not change, neither do the number of neutrons. Atomic number is the proton number which is equals to the number of protons, hence B and C is wrong. Mass number is the number of protons and neutrons. Hence it doesnt change too and D is wrong.

Only the number of electrons change when an atom forms an ion.

An ion with a -2 charge has? A) one missing protein B) two missing protons c) two missing electrons D) two extra electrons

Answers

Answer:

D.

Explanation:

It would not be gain because it would say +6 instead of -2. Having a -2 charge means it wants to loose 2 electrons so it can form a full shell of 8 electrons. It wants to be inert (stable).

how many moles of solute are present in 50.0 ml of 0.20 m kno3

Answers

Answer: Volume =  50.0 mL in liters : 50.0 / 1000 = 0.05 L

n = M x V

n = 0.20 x 0.05

n = 0.01 moles of solute

Explanation:

The number of moles of solute are present in 50.0 mL of 0.20 M of KNO₃ solution is 0.01 moles.

How do we calculate moles?

Moles will be calculated by using the molarity formula because molarity is define as the no. of moles of solute present in per liter of the solution as:

M = n/V, where

M = molarity of KNO₃ = 0.2 M

V = volume of solution = 50mL = 0.05L

Moles will be calculated as:

n = (0.2)(0.05) = 0.01 moles

Hence required moles are 0.01 moles.

A small magnet will stick to a refrigerator door, but a nail will not stick

because magnets attract certain types of metals.

which was why the magnet stuck to it.

Metals such as aluminium and copper aren't attracted by magnets which is

why the nails weren't attracted as a result of it being made with metals which magnets don't attract.

b. nuclear fission produces less energy than burning coal or oil.

c. nuclear waste must be safely stored for many years

d. nuclear waste must be incinerated

Answers

The biggest disadvantage of using nuclear power to produce electricity is the nuclear waste must be safely stored for many years.

What is nuclear power?

Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from:

Nuclear fission Nuclear decay and Nuclear fusion reactions

Nuclear reactions produces high amount of energy and many waste materials which are non degradable and will stay in the environment for the long time.

Hence, nuclear waste must be safely stored for many years.

What mass of sulfur trioxide is formed from 96g of sulfur dioxide?

2 SO2+O2 –> 2 SO3

Answers

Answer:

120 g SO3

Explanation:

128 g SO2  -> 160 g SO3

 96 g SO2  -> x

x= (96 g SO2 * 160 g SO3)/128 g SO2

x= 120 g SO3

The mass of sulfur trioxide, SO₃, formed is 120 g

The balanced equation for the reaction is given below:

2SO₂ + O₂ —> 2SO₃

Next, we shall determine the mass of SO₂ that reacted and the mass of SO₃ produced from the balanced equation. This can be obtained as follow:

Molar mass of SO₂ = 32 + (16×2)

= 32 + 32

= 64 g /mol

Mass of SO₂ from the balanced equation = 2 × 64 = 128 g

Molar mass of SO₃ = 32 + (16×3)

= 32 + 48

= 80 g /mol

Mass of SO₃ from the balanced equation = 2 × 80 = 160 g

Thus,

From the balanced equation above,

128 g of SO₂ reacted to produce 160 g of SO₃.

Finally, we shall determine the mass of SO₃ by the reaction of 96 g of SO₂. This can be obtained as follow:

From the balanced equation above,

128 g of SO₂ reacted to produce 160 g of SO₃.

Therefore, 96 g of SO₂ will react to produce = [tex]\frac{96 X 160}{128}\\\\[/tex] = 120 g of SO₃.

Therefore, the mass of SO₃ formed is 120 g

Answer: The reaction of one mole of oxygen [tex](O_2)[/tex] releases 445 kJ of energy.

Explanation:

Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and [tex]\Delta H[/tex] for the reaction comes out to be negative.

Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and [tex]\Delta H[/tex] for the reaction comes out to be positive.

[tex]CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(l)[/tex]  [tex]\Delta H=-890kJ[/tex]

on halving the reaction, enthalpy also becomes half

[tex]\frac{1}{2}CH_4(g)+O_2(g)\rightarrow \frac{1}{2}CO_2(g)+H_2O(l)[/tex]  [tex]\Delta H=-445kJ[/tex]

Thus The reaction of one mole of oxygen [tex](O_2)[/tex] releases 445 kJ of energy.

What is Gay Lussac's law?

According to this law at constant volume of gas, pressure is directly proportional to the temperature of the gas and it is represented as:

P ∝ T.

It means that if pressure increases then temperature is also increases or if pressure decreases then temperature will also decreases.

Answers

Answer:

Heat energy (Q) = 1.9925 KJ = 2 KJ (Approx)

Explanation:

Given:

Mass of copper (M) = 45 gram

Change in temperature (ΔT) = 71°C - 12°C = 59°C

Specific heat (c) =0.75 j /g*c

Find:

Heat energy (Q) = ?

Computation:

Heat energy (Q) = Mass(M) × Change in temperature (ΔT) × Specific heat (c)

Heat energy (Q) = 45 gram × 59°C × 0.75 j /g*c

Heat energy (Q) = 1991.25 J

Heat energy (Q) = 1.9925 KJ = 2 KJ (Approx)

Determine the mass of hydrogen in a 2.5 sample of ammonia
show work using dimensional analysis

Answers

Answer:

[tex]\large \boxed{\text{0.44 g}}[/tex]  

Explanation:

1. Calculate the molar mass of ammonia

1  N = 1 × 14.01    g = 14.01    g

3 H = 3 ×  1.008 g =  3.024     

                   TOTAL = 17.03   g

2. Calculate the mass of hydrogen

So, there are 3.024 g of H in17.03 g of NH₃.

The conversion factor is either

[tex]\dfrac{\text{3.024 g H}}{\text{17.03 g NH}_{3}} \text{ or } \dfrac{\text{17.03 g NH}_{3}}{\text{3.024 g H}}[/tex]

We want to find grams of H, so we choose the one with grams of H on top.

[tex]\text{Mass of H} = \text{2.5 g NH}_{3} \times \dfrac{\text{3.024 g H}}{\text{17.03 g NH}_{3}} = \textbf{0.44 g H}\\\\\text{The mass of H is $\large \boxed{\textbf{0.44 g}}$}[/tex]
