Answers

Answer 1

The nucleus of the atom is the heaviest part of the atom.

The nucleus consists of neutrons and protonsBoth neutrons and protons have masses, but only protons have chargesThe nucleus contains all the positive charges of an atomThe mass of an atom is the sum of the numbers of protons and neutrons in a nucleus

When the ratio of neutrons to protons is too high, the nucleus becomes unstable and Beta emission has to take place.

In beta emission, an extra neutron gives rise to a proton and an electronThe electron is ejected from the nucleus

Is CaO a molecular compound?

Answers

Answer:

It's a Ionic compound

Explanation:

To tell if CaO (Calcium oxide) is ionic or covalent (also called molecular) we look at the Periodic Table that and see that Ca is a metal and O is a non-metal. When we have a metal and a non-metal the compound is usually considered ionic.

Because we have a metal and non-metal in CaO there will be a difference in electronegativity between the metal and non-metal. This difference results in an electron(s) being transferred from the metal (lower electronegativity) to the non-metal (higher electronegativity). The results in the metal becoming a postitive ion and the non-metal a negative ion. The two opposite charges are attracted and form the ionic bond between atoms in Calcium oxide.

ZnS (s) + AIP(s) → AI₂S₂(s) + Zn P₂(s)

Answers

Answer:

3 ZnS (s) + 2 AIP(s) ---> AI₂S₃(s) +  Zn₃P₂(s)

Explanation:

I believe you are asking for this reaction to be balanced. However, after looking more closely, those are not the products that would be created from the reactants. Assuming this is a double-displacement reaction, and taking the most common charges of the ions into consideration, the actual products would be AI₂S(s) + ZnP₂(s). I apologize if I assumed incorrectly.

For an equation to be balanced, there needs to be the same amount of each element on both sides of the equation.

The unbalanced equation:

ZnS (s) + AIP(s) ---> AI₂S₃(s) + Zn₃P₂(s)

Reactants: 1 zinc, 1 sulfur, 1 aluminum, 1 phosphorus

Products: 3 zinc, 3 sulfur, 2 aluminum, 2 phosphorus

As you can see, there is an unequal amount of each element on the reactants and products side. To balance the equation, coefficients in front of the compound(s) will be necessary.

If a snail crawls at a rate of 228.16cm/s, what is its speed in miles per hour?

Answers

If a snail crawls at a rate of 228.16cm/s, Its speed in miles per hour will 5.10 miles/hour

What is speed ?

The rate at which someone or something moves or operates or is able to move or operate.

Snail covers distance in 1 seconds = 228.16 cm

It covers in 60 seconds (1 min) = 228.16 cm x 60 = 6mtrs

It covers in 60 minutes (1 hour) = 228.16 cm x 60 x 60 = 821376 cm

Now, lets convert cm to miles :

As,                    1 cm = 6.21371 x 10⁻⁶ miles

Thus,     821376 cm = 5.10 miles

B. The gravitational forces must overcome inertia and friction for the tides to take effect on water.
C. Water is relatively immune to the force of gravity delaying the tidal process.
D. There is no delay because the effects of gravity is constantly acting on bodies of water.

Answers

There is no delay because the effects of gravity are constantly acting on bodies of water. Hence, option D is correct.

What is the gravitational effect?

Gravitation or just gravity is the force of attraction between any two bodies.

The Moon exerts over twice the gravitational pull of the Sun on Earth's tides because of its proximity to Earth. -The lunar tidal bulges are about twice the size of the solar tidal bulges. -The Sun's contribution to the tides is less than that of the Moon.

When the sun and moon are perfectly unaligned (they form a 90-degree angle relative to the earth), there are still tides because the moon's gravitational gradient is stronger than the sun's. The sun's gravitational gradient never completely cancels out the moon's.

Hence, option D is correct.

Concentration =
M
-How many milliliters of 9.36 M perchloric acid solution should be used to prepare 1.50 L of 0.700 M ?

mL

Answers

For all three questions, we will use the fact that

molarity = (moles of solute)/(liters of solution)

1) For 175 mL of solution at 0.203 M, this means that:

0.203 = (moles of solute)/0.175moles of solute = 0.035523 mol

Considering the hydrochloric acid solution, if we have 0.035523 mol, then:

6.00 = 0.035523/(liters of solution)liters of solution = 0.035523/6.00 = 0.0059205 = 5.92 mL (to 3 sf)

2) If there is 20.3 mL = 0.0203 L, then:

8.20 = (moles of solute)/0.0203moles of solute = 0.16646 mol

This means that the molarity of the diluted solution is:

0.16646/(0.200) = 0.832 M (to 3 sf)

3) If we need 1.50 L of 0.700 M solution, then:

0.700 = (moles of solute)/1.50moles of solute = 1.05 mol

Considering the 9.36 M acid solution, from which we need 1.05 mol of perchloric acid from,

9.36 = 1.05/(liters of solution)liters of solution = 1.05/9.36, which is 0.11217948717949 L, or 112 mL (to 3 sf)

2. A solution is made by dissolving 3.88 g of NaCl in enough water to make 67.8 mL of solution. What is the concentration of sodium chloride in units of weight/volume percent?

Answers

The concentration of sodium chloride in the solution is 5.72% (weight/volume percent).

How to calculate the weight/volume percent concentration?

Weight/volume percent concentration (w/v) expresses the amount of solute (in grams) dissolved in a given volume of solution (in milliliters). Specifically, it is defined as the weight of the solute divided by the volume of the solution, multiplied by 100.

To calculate the weight/volume percent concentration, we need to determine the mass of NaCl per volume of the solution.

First, we need to convert the volume of the solution from milliliters (mL) to liters (L):

67.8 mL = 0.0678 L

Next, we calculate the concentration of NaCl in grams per liter (g/L):

Concentration = Mass of solute ÷ Volume of solution

Concentration = 3.88 g ÷ 0.0678 L

Concentration = 57.2 g/L

Finally, we convert the concentration to weight/volume percent by multiplying by 100:

Weight/volume percent = Concentration x 100

Weight/volume percent = 57.2 g/L x 100

Weight/volume percent = 5.72%

Therefore, the concentration of NaCl in the solution is 5.72% (weight/volume percent).
